Do ACL braces work?

Posted on | by Matthew Blackwell

Anterior cruciate ligament (ACL) injuries are a common concern in sports and physical activities, often requiring extensive rehabilitation and sometimes even surgery. Knee braces are one of the most prescribed devices in the orthotic industry, with medical device companies such as Enovis™ supplying a range of knee bracing solutions for ACL protection and injury prevention. But despite their widespread use, the question remains: Do ACL braces really work?

This article explores the world of ACL braces, examining their purported benefits and the scientific evidence behind their effectiveness, before presenting a new product for people looking to safeguard their knee health.

ACL injury: definition and causes

The anterior cruciate ligament (ACL) serves as an essential stabilizer within the knee joint, preventing the tibia (shine bone) from shifting forward in relation to the femur (thigh bone) and ensuring rotational stability.

While an ACL tear can occur due to excessive external force applied to the knee, it’s distinctive in that it can also happen without direct contact, which accounts for 70% of reported ACL injuries1.

In sports like football and other field/court activities, non-contact ACL injuries usually occur during abrupt stops, sudden changes in direction, or when landing from a jump with insufficient knee and hip flexion (at or near full extension)2. The typical scenario involves a combination of deceleration, directional change while the foot is planted, and the knee being near or fully extended. This action can put excessive twisting force on the ACL, leading to strain or rupture.

Evidence that wearing a knee brace can help prevent ACL injury

Clinical studies have demonstrated that wearing a knee brace during activity can help prevent ACL injury as well as protect against reinjury3,4,5.

In a systematic review of current evidence carried out in 2023, Tuang et al. found that protective knee braces were able to control forwards and backwards and sideways knee motion and decrease ACL load/strain during high-risk maneuvers, which may in turn decrease the risk for non-contact ACL injuries3.

With around half of ACL injuries occurring in 15–25-year-olds6, knee bracing effectiveness for young people is a key concern for many. Perrone et al.’s 2019 study involved prescribing knee braces to a group of adolescents post-ACL surgery. The results showed that post-operative use of functional bracing can result in reduced reinjury following ACL reconstruction4.

Bodendorfer et al.’s 2013 study also recommended knee bracing for ACL patients. It found that people with ACL-deficient knees can benefit from the control and proprioception functional bracing can offer. And for highly active athletes participating in high-impact sports, knee bracing further offers protection to the knee ligaments and meniscus during impact from the side5.

How DonJoy® knee braces help prevent ACL injury

DonJoy® is a name synonymous with knee bracing. A key brand of Enovis, it has been manufacturing and supplying braces for knee ligament protection since the late 1970s, using patented technology that reduces ACL strain.

The Four-Points-of-Leverage™ system featured in DonJoy knee braces consists of a rigid cuff and strap configuration. Through this, a posterior force is applied to the tibia, which prevents anterior movement and reduces the strain on the ACL7.

The second key technology in DonJoy knee braces is the FourcePoint® hinge. This complements the Four-Points-of-Leverage design by damping knee joint extension, which improves the mechanical performance of the brace and reduces shear forces at the knee. The hinge resistance kicks in during the last 25 degrees of knee extension, targeting the vulnerable “at-risk” position.

When combined, the FourcePoint hinge and the Four-Points-of-Leverage design create a more comfortable brace that diminishes anterior shear forces on the knee. This stability is particularly advantageous for people wanting to prevent ACL injuries during activity and those recovering from ACL injuries, as it eases strain on the deficient or healing ACL graft8,9.

Defiance® PRO: custom knee ligament bracing from DonJoy

When it comes to ligament knee bracing, few product names stand out more than Defiance®. Alongside off-the-shelf alternatives, DonJoy’s flagship custom brace has been protecting knees for decades. Now with the Defiance® PRO taking the design to the next level, those looking to prevent ACL injuries have a new name to trust in.

Featuring the proven Four-Points-of-Leverage and FourcePoint technologies, Defiance PRO also provides a range of customizable elements to offer patients an enhanced wearing experience.

Every Defiance PRO order begins with the patient receiving a precise measurement of their leg from an Enovis representative. These measurements are then used to build a brace exactly matched to the customer’s leg for an even closer and more comfortable fit.

10 reasons why skiers and snowboarders should wear a DonJoy® knee brace

Posted on | by Matthew Blackwell

As winter sports enthusiasts hit the slopes, the importance of protecting vulnerable joints cannot be overstated. For skiers and snowboarders, the rigors of downhill adventures can take a toll on the knees. Thankfully DonJoy® knee braces are clinically proven to protect the knee and safeguard against ligament injuries.1 Here are ten compelling reasons why skiers and snowboarders should consider wearing a DonJoy rigid knee ligament brace.

1. Dynamic Stability

The unpredictable terrain of snowy slopes demands dynamic stability. DonJoy knee braces feature the Four-Points-of-Leverage™ system, a combination of a rigid cuff and straps that provides a constant dynamic load and is clinically proven to reduce anterior cruciate ligament (ACL) strain.2

Four points of leverage

2. Prevent Ligament Injuries

The lateral movements and sudden stops inherent in skiing and snowboarding can put stress on knee ligaments, and when it comes to ligament injuries, prevention is better than any cure. DonJoy’s patented FourcePoint® Hinge keeps the knee out of the “at risk” position, helps prevent anterior tibial translation, and dampens knee joint extension, helping to protect the knee from injury.3

3. Post-Injury Protection

With a re-injury rate of 5-10% for people who have suffered an ACL injury, protecting the knee is essential.4 The Four-Points-of-Leverage technology featured on DonJoy knee braces effectively reduces ACL strain, which can be crucial during rehabilitation while the graft is remodelling.2

4. Enhance confidence

The protection offered by a DonJoy brace can give skiers and snowboarders the confidence to push their limits with greater assurance.

5. Important for women and young people

Of those who suffer ligament injuries, women and young people are the most susceptible. With 50% of ACL injuries occurring in 15-25 year olds,5 and women 8x more likely to injure an ACL,6 it is even more essential for them to wear a knee brace while skiing or snowboarding.

6. Unique braces made to measure

Every Defiance and A22® knee brace is made to the specific measurements of the customer’s leg for an even closer and more comfortable fit.

7. Off-the-shelf options for a fast fix

Introducing DonJoy ActyLight®: fit-and-forget ankle support

Posted on | by Matthew Blackwell

Lateral ankle sprains are one of the most common sports-related injuries1; in the United States alone, more than 23,000 people suffer a lateral ankle sprain every day.2 To help address this situation, DonJoy® introduces the new DonJoy ActyLight®, an ankle support so comfortable and easy to fit, you’ll forget you’re even wearing it.

What is an ankle sprain, and why do they happen?

When the ligaments of the ankle are damaged, this is called a sprain. If the foot suddenly rolls inward during activity, the subsequent forceful ankle plantarflexion and inversion can result in stretching and tearing of the ankle ligament fibers. As well as causing swelling and bruising, sprains are usually painful, especially when the person attempts to put weight on the foot.

Ankle sprains are categorized into three grades of severity:

  • Grade I (Mild): This involves minor stretching and tiny tears in the ligament fibers, leading to mild tenderness and swelling around the ankle.
  • Grade II (Moderate): In this grade, there is partial tearing of the ligament, resulting in moderate tenderness and swelling around the ankle. Certain movements can cause some abnormal looseness in the ankle joint.
  • Grade III (Severe): This is the most severe grade, where the ligament is completely torn. It leads to significant tenderness and swelling around the ankle, and certain movements can cause substantial instability in the ankle joint.

What is chronic ankle instability?

Approximately 40% of individuals who suffer an ankle sprain later develop chronic ankle instability (CAI) and report persistent symptoms.3,4 This condition is marked by sensations or instances of the ankle unexpectedly giving way.5

People with CAI commonly experience ongoing symptoms such as persistent swelling, pain, weakness, restricted ankle movement, instability, reduced self-reported functionality, and recurrent ankle sprains.5,6

CAI has been recognized as a precursor to ankle osteoarthritis (OA), with its onset typically happening a decade earlier than knee or hip OA.7

Chronic ankle sprains might necessitate surgical intervention through arthroscopic ligament reconstruction. Individuals with CAI are noted to exhibit both mechanical instability, related to structural changes around the ankle, and functional instability, which is associated with decreased sensorimotor and neuromuscular control.8

Bracing for chronic ankle instability

An ankle brace is worn to support and stabilize the ankle, either as a preventive measure or after an injury has occurred. These braces come in soft or semi-rigid varieties and are intended for one or more of the following purposes:

  • Improve ankle stiffness and thus mechanical stability9
  • Improve neuromuscular control10
  • Improve grounding of the foot10
  • Decrease excessive range of motion (ROM)9
  • Enhance proprioceptive acuity (the body’s ability to sense its own location, movement, and actions)11

Numerous clinical studies have been conducted to assess the effectiveness of ankle bracing in these areas.

In 1998, Vaes et al. discovered that the Aircast® Air-Stirrup® brace significantly reduced talar tilt in unstable ankles during static and dynamic tests, and it slowed down the simulated sprain speed.12

In a study from 2000, Hals et al. demonstrated a significant enhancement in shuttle-run performance among subjects with post-acute, mechanically stable yet functionally unstable ankle sprains when using the Aircast Sport Stirrup® brace.13

A randomized controlled trial conducted by Janssen et al. in 2014, involving 384 athletes who had experienced a lateral ankle sprain, revealed that using an Aircast A60™ brace was more effective than neuromuscular training in reducing the recurrence of ankle sprains.14

Habadi et al. (2014) showed the advantages of soft and semi-rigid ankle orthoses in improving the dynamic balance of individuals with functional ankle instability.15

And a 2020 systematic review by Reyburn and Powden concluded that the current body of research strongly supports the positive impact of ankle braces on the dynamic balance of individuals with CAI.16

Introducing ActyLight by DonJoy®: fit-and-forget ankle support

The convenience and comfort of the DonJoy ActyLight® ankle support means patients will forget they’re even wearing it.

Designed to deliver stability and protection for mild to moderate lateral ankle sprains, thanks to its removable bilateral stays, quick lace-locking mechanism, and step-in design, this modular brace can also be used for the prevention of ankle injuries.

All of this means that patients can rely on ActyLight throughout their journey of activity, from healthy, active use, to support following injury, and to prevention of reinjury in the future.

Why are there more ACL injuries in women’s football?

Posted on | by Matthew Blackwell

With the World Cup kicking off in Australia and New Zealand this year, the popularity of women’s football (soccer) is at an all-time high, with more women and girls getting involved every day. However, female football players are at a higher risk of anterior cruciate ligament (ACL) injuries compared to their male counterparts.1 Why are there more ACL injuries in women’s football, and how can knee bracing help in prevention and protection?

What is an ACL injury and how do they happen?

The anterior cruciate ligament (ACL) is one of the major stabilizing ligaments in the knee joint. Running diagonally in the middle of the knee, it prevents the tibia from sliding out in front of the femur and provides rotational stability to the knee.

ACL injury

Although the ACL can be torn when the knee receives excessive external force, unlike most other ligaments it can also be injured in non-contact situations, with the latter accounting for 70% of all reported ACL injuries.2

In football and other field/court sports, non‐contact ACL injury typically involves a sharp stop, a sudden change of direction, or landing from a jump with inadequate knee and hip flexion (at or near full extension).1 The most common occurrence is from a combination of a deceleration manoeuvre with a change of direction while the foot is planted and the knee is nearly or fully extended; the excessive torsional force that results from the player trying to change direction can potentially strain or rupture the ACL.

Why ACL injuries are more common in female footballers

Studies have shown that female athletes are two- to ten-times more likely to suffer an ACL injury than male athletes.1 The phenomenon has had a noticeable impact on the 2023 Women’s World Cup, with several high-profile players missing out on the tournament as a result. There are a number of factors involved.

Differences in anatomy

The anatomy of female players predisposes them to an increased incidence of ACL injuries. Women generally have slimmer muscles, and a more considerable pelvic angle than men. The Q-angle, which refers to the angle formed between the hip and the knee, is higher in females, leading to more exertion placed on the ACL. The variance in the anatomy of the knee joint and surrounding bones results in lower overall knee stability, amplified by repetitive jumps or twists.

Hormonal predisposition

Research has suggested that the menstrual cycle poses a higher risk for ACL injuries during ovulation.3 Estrogen levels are higher during ovulation; high estrogen levels alter the collagen production, resulting in increased ligament laxity which can lead to decreased levels of overall knee stability.

Biomechanical Aspects

Studies have revealed distinct differences in landing techniques between men and women following a jump or leap.4 Females have landing mechanisms which increase the pressure placed on their knees. Furthermore, females are more likely than males to land with knee valgus position, making it harder to control the forces and positions during motions leading to tearing of the ACL.

How a knee brace can help reduce ACL injuries

Clinical studies have demonstrated that wearing a knee brace during activity can help prevent ACL injury as well as protect against reinjury.5,6,7 DonJoy® knee braces utilize patented technology that reduces ACL strain.

The Four-Points-of-Leverage™ system featured in DonJoy knee braces consists of a rigid cuff and strap configuration. Through this, a posterior force is applied to the tibia, which prevents anterior movement and reduces the strain on the ACL.8

Four points of leverage

FourcePoint® hinge technology works to enhance DonJoy’s Four-Points-of-Leverage design by damping knee joint extension, which improves the mechanical performance of the brace and reduces shear forces at the knee. Addressing the “at-risk” position, the hinge resistance engages in the last 25 degrees of knee extension.

FourcePoint hinge

The FourcePoint hinge combined with the Four-Points-of-Leverage cuff and strapping design provides a more comfortable brace that reduces anterior shear forces at the knee. The stability this provides is beneficial for both female football players looking to avoid ACL injuries during training, and those who are recovering from an existing injury, as it reduces strain on the healing ACL graft.9,10

How a soft brace can help improve proprioception

Posted on | by Matthew Blackwell

Proprioception is an important part of our everyday lives. It influences our balance, stability, and posture, and is essential for the motor coordination of our bodies. But what happens when proprioception is impaired, and how can wearing a soft brace help improve it?

What is proprioception?

Proprioception, also known as kinesthesia, is the body’s ability to sense its own position and movement, as well as force and heaviness.

Sensory neurons throughout the body—collectively known as proprioceptors—process stimuli and provide feedback that the body uses to coordinate its movements.

For instance, if receptors in and around a limb’s muscles and tendons sense risky levels of continuous deformation, they will “tell” the body to initiate reflexes to help stabilize and protect the limb from excessive movements.

How can injury affect proprioception?

Though proprioception is a difficult sensation for an individual to identify, its impairment or loss is far more keenly felt.

In extreme cases, such as an autoimmune response to an infection that attacks the body’s sensory neurons, the sense of position, movement, and touch can be completely lost. Without the ability to coordinate their movements, patients who experience this kind of condition can find themselves unable to stand, walk, or physically interact with their surroundings.1

In more common conditions, such as knee osteoarthritis, the proprioceptors in and around the knee joint can be negatively impacted, and the consequent reduced sensory input can compromise normal knee movement and impair postural and protective reflexes.2 This in turn can cause loss of stability and balance, leading to falling.

Acute injuries, such as sprains and strains, can damage soft tissue containing proprioceptors, thereby impairing proprioception and increasing the chance of risky movements.

How can a soft brace improve proprioception?

Studies have shown that wearing a soft brace can contribute to improvements in proprioception.2,3

Although the exact details of how this process works are unknown, researchers hypothesize that wearing a soft brace increases stimuli on proprioceptors in the skin, as well as pressure on the underlying muscles and joint capsule that it covers.4,5

The benefits of this can include improvement in physical function, better control of the involved joint, and a reduction in pain.2,3

Introducing a new range of proprioceptive soft braces from DonJoy®

Sometimes staying active means staying supported. DonJoy’s® new range of soft braces aids proprioception to help people continue their everyday activities.

The range covers all the major joints, comprising two knee supports, two ankle supports, an elbow support, and a wrist support, all of which are available in a wide range of sizes to accommodate different body types.

Each brace is made from soft 3D elastic compression fabric that stretches with the wearer’s movements while providing support and proprioceptive feedback. This means patients get the stability and control they need to help prevent injury while remaining comfortable, making these products well-suited to all kinds of activities, from tennis and jogging, to walking and gardening.

These braces also include a number of individual features to provide enhanced function. For instance, the GenuForce® Xpert knee brace’s semi-rigid polycentric hinges provide greater lateral support and stability, while ManuForce®’s adjustable strapping and malleable hand stay help offer adaptable compression, stabilization, and relief for the wrist.

Low back pain relief, from DonJoy®

Posted on | by Matthew Blackwell

As one of the most common health problems, low back pain is a significant problem not just for individuals, but also their families and communities.1 The condition is defined as “activity-limiting low back pain (+/- pain referred into 1 or both lower limbs) that lasts for at least 1 day”.1

As the population ages, the number of people around the world suffering from low back pain is only going to increase.1 Thankfully, back supports such as Lumbostrap 35 and Dorsostrap 55 from DonJoy® can help relieve low back pain.

What are the causes of lower back pain?

There are many potential causes of low back pain:

  • Muscle or ligament strain from over-stretching (pulling), heavy lifting, twisting the spine while lifting, vigorous exercise at the gym, or a sudden awkward movement
  • Sciatica happens when a weakened and bulging disc is pressed against the sciatic nerve. This can cause intense pain which goes down one leg. This cause can be confirmed through imaging techniques
  • Spinal stenosis happens when the space around the spinal cord narrows and puts pressure on the spinal nerves
  • Prolonged periods of time incorrectly sitting at your desk (poor posture) can also cause lower back pain
  • A herniated disc occurs when an intervertebral disc slides out of position, and spondylolisthesis is when a vertebra slides out of position

Bracing for low back pain relief

A conservative treatment option for low back pain is to wear a back brace. As well as improving postural control,2 the support these devices provide can help to alleviate symptoms associated with low back pain through mechanisms such as activation of the trunk muscles and stabilizing the spine.3,4 They can also help to reduce the use of medication for the condition.5

In patients with low-back pain, walking with abdominal bracing activates the trunk muscles more than walking without an abdominal brace, particularly at slower speeds.3 This means patients incapable of walking faster might possibly benefit from abdominal bracing during walking exercise.3

Patients suffering from low back pain may find that the process of sitting down or standing up can be painful. A study by Im et al. (2021) found that wearing an extensible or a non-extensible lumbar brace has beneficial effects on the biomechanical factors of the sit-to-stand movement in office workers with low back pain.6 It also resulted in immediate reduction of pain intensity and pain-related anxiety.6

Do lumbar braces cause muscle weakness?

One concern about using bracing for low back pain is that it can weaken the trunk muscles. This comes from the assumption that the brace partly replaces the stabilizing function of the trunk muscles.

However, a number of contemporary studies show that back braces do not cause weakness in trunk muscles.7 There is no evidence to the contrary.7

Get low back pain relief with Lumbostrap 35 and Dorsostrap 55 back supports from DonJoy

Lumbostrap 35 and Dorsostrap 55 are two new back supports from DonJoy. These semi-rigid unisex corsets are designed for support and stabilization of the spine and relief of low back pain.

With a height of 35 cm, Lumbostrap 35 provides support and stability for the lumbar spine from S1-T10. At 55 cm high, Dorsostrap 55 covers the dorsal-lumbar spine from S1-T4.

Lumbostrap 35 is anatomically contoured to help provide a comfortable fit and improved patient compliance. Application is made easy through the use of a front closure with a hand loop.

The support’s double bilateral elastic straps are configured in a pulley system, providing independent superior and inferior adjustment of compression level. Conveniently placed within reach, they are easily affixed using hook-and-loop closures.

And four semi-rigid pre-shaped dorsal stays help provide adjustable back support. Two of the stays can be removed and replaced with a more rigid pair for additional stability, and all of them can be reshaped by hand to achieve optimal comfort and fit.

Dorsostrap 55 includes all of the above features, as well as a pair of reverse shoulder straps. Using a traction pulley system, these straps provide adjustable tension to pull the shoulders back and straighten the back, thereby helping to improve kyphotic posture.

Both supports are lightweight, low profile, and breathable, allowing them to be worn comfortably for extended periods, and to fit more easily under clothing. To aid hygiene, they are made from odor-resistant materials which do not include natural rubber latex and are easy to clean.

Does a back brace help with kyphosis?

Posted on | by Matthew Blackwell

In some people, kyphosis can be a debilitating spine condition that left untreated can have a severe impact on people’s lives. For older people in particular, if severe, the consequences can be life-threatening. However, evidence suggests that wearing a back brace can help address the symptoms of kyphosis.

What is kyphosis?

Kyphosis is defined as excessive curvature of the spine in the sagittal (front to back) plane. Normally there is 20° to 45° of curvature in the upper back, but anything in excess of 45° is called kyphosis (Website Source).

The condition gives the top of the back a more rounded appearance. The back may be painful, flexibility of the spine is reduced, and tiredness may also be experienced (Website Source).

What causes kyphosis?

In addition to spinal injuries, there are a number of different ways in which the upper back can become overly curved (Website Source):

  • Postural kyphosis—bad posture from slouching or carrying heavy bags can affect the muscles and ligaments supporting the spine and increase spinal curvature
  • Scheuermann’s kyphosis—vertebrae that do not develop properly can become abnormally shaped and out of position
  • Congenital kyphosis—when a child’s spine does not develop correctly in the womb, the vertebrae can become fused together
  • Age-related kyphosis—as people grow older, the spine can become increasingly curved

Why is kyphosis a problem for older people?

Among the elderly population, the most commonly reported symptoms are weak back extensor muscle strength, loss of spinal mobility, and pain, along with the general degenerative components such as disc dehydration and changes in vertebral shape/wedging1.

For older people, kyphosis can have significant impact on function, quality of life, and mortality. Because it has a negative effect on gait and balance, older kyphosis sufferers are at increased risk of falls and fractures. Furthermore, severe kyphosis reduces the amount of space in the chest, mobility of the rib cage, and expansion of the lungs, which may lead to breathing problems, particularly in women2.

Older women with kyphosis are 70% more likely to suffer a fracture, regardless of age or prior fracture, and this risk increases as the condition progresses3.

How is kyphosis treated?

According to the NHS, it is usually only severe cases of kyphosis that require surgical treatment (Website Source). The condition can usually be improved by correcting posture through exercise and physiotherapy, while over-the-counter analgesics can be used to manage pain.

For children with mild to moderate kyphosis, bracing is recommended to minimize the progression of the curve whilst the spine is still growing (Website Source). In adolescents, bracing using an orthosis has been seen to reduce kyphosis ranging from 55 to 80°1.

In patients over the age of 60, bracing improves the balance score, and reduces spinal deformity and pain. If there is lumbar spine involvement, bracing and exercises should be prescribed for patients with kyphosis. Bracing becomes more of an attractive option for elderly patients when considering that the high risk of surgery for this age group means that surgical intervention is less likely to be recommended1.

What is a TLSO brace?

A thoracolumbosacral orthosis (TLSO) is a brace worn over the whole or part of the thoracic, lumbar, and sacral portions of the spinal column. TLSOs are prescribed to control motion, correct deformity, and/or compensate for weakness3.

Get customizable back support for kyphosis with IsoFORM™ TLSO

The IsoFORM™ TLSO back brace from DonJoy® is designed to provide motion restriction, creating a dynamic environment for healing within the thoracolumbar and lumbar spine.

It is intended for acute pain relief by thoracic postural extension alignment, compression fractures of the thoracic spine, osteoporosis, thoracic mechanical back pain, and kyphosis.

IsoFORM TLSO’s customizable lumbar belt encompasses the torso and restricts flexion and rotation, thereby providing stability for the trunk. Along with the posterior extending straps, this promotes postural correction for the upper spine, helping to relieve the symptoms of kyphosis.

The brace’s many customizable features allow it to be modified to suit the patient and achieve the optimum performance. The malleable telescoping sternal bar can be shaped for a custom fit, while the straps can be positioned in over-the-shoulder or underarm configurations to aid comfort.

Targeted compression and support are provided by a dual pulley system and an overlapping panel system consisting of anterior, posterior, and lateral extension panels.

Comfortable to wear and easy to don and doff, IsoFORM TLSO is available in two sizes (Small/medium and large/extra-large), and fits hips from 71 to 152 cm in circumference.

Supplemental aid is available in the form of a reusable hot/cold pack accessory sold separately for use with the brace. Simply warm up or freeze the pack before placing it into the brace’s purpose-built pocket to deliver heat or cooling therapy. It can be used for common aches, pains, swelling, and bruising, and provides fast relief for sore and stiff joints, muscle aches and pain, and muscle tension and cramps.

As well as kyphosis, IsoFORM TLSO is suitable for people with compression fractures of the thoracic spine, osteoporosis, and thoracic mechanical back pain.

The experts striving to improve anterior knee pain treatment

Posted on | by Matthew Blackwell

One in three patients of sports medicine clinics seek treatment for anterior knee pain1,2. The pain caused by this condition can prevent exercise or participation in sports, and can even lead to chronic disability and inability to work.

But a group of world experts is on a mission to improve the understanding and treatment of anterior knee pain. Along with knee brace manufacturers like DonJoy, their goal is to get people moving again.

What is anterior knee pain?

Anterior knee pain is another name for Patellofemoral Pain Syndrome (PFPS), a term used to refer to pain originating from the patellofemoral joint or its surrounding soft tissues. Due to the pain being felt in all parts of the knee, anterior knee pain is actually a misleading name, though its use remains popular.

This chronic condition usually worsens with activities such as running, squatting, and climbing stairs, as well as sitting. 

What is The Patellofemoral Foundation?

Founded in 2003 by Dr John Fulkerson, The Patellofemoral Foundation is a non-profit organization dedicated to improving the care of individuals with anterior knee problems through targeted education and research.

The author of many articles and books on patellofemoral pain, Dr Fulkerson is Professor of Orthopedic Surgery at Yale University. As well as sitting on the boards of a range of orthopedic associations, he has also been team doctor for the U.S. Olympic Ice Hockey team, the NHL Hartford Whalers, and the AHL Hartford Wolfpack.

Over the past two decades, The Patellofemoral Foundation has made progress in the understanding of anterior knee pain. Anatomic and clinical studies funded by it or carried out by its members have revealed previously unrecognized sources of pain leading to specific pain treatments around the front of the knee3.

During this time, technological advancements in radiology such as computerized tomography and MRI have also allowed greater understanding of the mechanical behavior of the patella.

The Patellofemoral Foundation

Yet despite this progress, much remains to be done to improve things for patients suffering from anterior knee pain. Among the objectives the foundation still seeks to achieve are to refine the indications for anterior knee pain management and surgery, improve bracing and non-operative measures, standardize operative approaches, and develop an educational network that reaches deep into the sports medicine and orthopedic communities.

One of the companies supporting the foundation in its efforts is Enovis. With its DonJoy brand offering a full range of patellofemoral knee braces, the orthopedics manufacturer has an important role to play in the conservative management of patients with anterior knee pain.

Tru-Pull® and the role of bracing in anterior knee pain treatment

A conservative aspect of anterior knee pain treatment is knee bracing. Wearing a patellofemoral knee brace can increase stability of the patella to reduce anterior knee pain4.

Developed in partnership with Dr Fulkerson, DonJoy’s Tru-Pull Advanced® knee brace is designed to place a dynamic pull on the patella during knee extension to improve alignment and reduce anterior pain.

Available in sleeve or hinged versions, the Tru-Pull Advanced provides support for patients with patellofemoral malalignment, subluxation, and dislocations.

Also available is the Tru-Pull Lite™, a shorter, more slimline version for enhanced comfort and ease of use. It is recommended for acute mild to moderate anterior knee pain, support for patella instability, lateral subluxation, and maltracking.

How wearing a soft brace can help jumper’s knee pain

Posted on | by Matthew Blackwell

One of the risks of regular participation in sports and physical activity is the potential for incurring overuse injuries such as jumper’s knee or Osgood-Schlatter disease. Painful conditions like these can be a barrier to further participation, but evidence shows that wearing a soft brace can help prevent or reduce knee pain,1,2 and a new elastic knee support from DonJoy could offer just the solution.

What is jumper’s knee?

The tendon which connects the kneecap (patella) to the shin bone (tibia) is called the patellar tendon. Inflammation of this tendon is called patellar tendonitis – more commonly known as “jumper’s knee.”

Jumper’s knee is an overuse injury often sustained from sporting activities involving repeated jumping on hard surfaces. The repetitive stress placed on the patella tendon from jumping and landing puts strain on the tendon which can leave it inflamed.

As well as causing swelling, jumper’s knee also causes pain below the patella, which can be felt more acutely when jumping, running, walking, or when bending and straightening the leg.

What is Osgood-Schlatter disease?

Another potential source of knee pain is Osgood-Schlatter disease. This condition causes painful swelling where the patella tendon connects to the top of the tibia. The most common sufferers of Osgood-Schlatter disease are young athletes – particularly boys aged 10-15 – who take part in sports or activities involving lots of running and/or jumping.

While they are still growing, the ends of children’s bones have not yet hardened, making them more susceptible to stress. Activities that put stress on the knee, such as running, bending, or squatting, can irritate these areas of cartilage and lead to painful swelling.

How to help jumper’s knee pain or Osgood-Schlatter disease

There are a number of ways to help prevent or reduce jumper’s knee pain or Osgood-Schlatter disease:

  • Follow the RICE protocol. REST the knee where possible. Apply an ICE pack to the knee for up to 30 minutes. Wear an elastic support on the knee for COMPRESSION. And use a pillow for ELEVATION to raise the foot and reduce swelling
  • Anti-inflammatories can help with the pain and swelling
  • Wear a soft brace. The support that soft braces provide can help to prevent jumpers’s knee, or aid recovery

Try DonJoy PateLax™ – flexible support for the patella

DonJoy PateLax™ is a new knitted elastic support designed to protect and support the patella, as well as provide relief at the patellar tendon insertion. It can be used to address overuse injuries such as jumper’s knee and Osgood-Schlatter disease.
