Knee osteoarthritis (OA) is one of the most widespread musculoskeletal conditions in the world \u2014 and its impact on daily life can be profound. Whether you are a patient struggling to walk to the local shops, or a clinician searching for effective conservative management options, understanding the role of knee OA bracing is increasingly important. The evidence is compelling: the right brace, fitted correctly, can reduce pain, improve mobility, and in some cases delay or even prevent the need for surgery.<\/p>\n\n\n\n
Knee OA affects an estimated 22.9% of people aged 40 and over \u2014 that is 654 million people globally in this age group alone.1<\/sup> Radiographic evidence of knee OA is even more prevalent, detected in 28.7% of the population across all ages, though not all cases are symptomatic.1<\/sup> The World Health Organization estimates that 344 million people living with osteoarthritis (across all joints) experience moderate or severe levels that could benefit from rehabilitation.2<\/sup><\/p>\n\n\n\n For many patients, the journey from early symptoms to the operating theatre is a long one. Research by London et al. calculated that approximately 20% of American patients with symptomatic knee OA linger in what is known as the “treatment gap” \u2014 the period after conservative treatments have been exhausted but before surgical intervention \u2014 for up to 10 years. For younger patients, this gap can stretch to 20 years, a significant period of pain, reduced activity, and diminishing quality of life.3<\/sup><\/p>\n\n\n\n Knee OA does not progress in a straight line. It is driven by a self-reinforcing cycle of interconnected problems. Malalignment of the knee \u2014 where the joint is not tracking correctly \u2014 leads to aberrant biomechanics and increased compartment loading, which in turn causes pain. Pain leads to decreased activity, which contributes to weight gain and muscle weakness, which further destabilizes the joint, and so the cycle continues.<\/p>\n\n\n\n Conventional pharmacological approaches such as analgesics and Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) can reduce pain and improve quality of life, but they do not address the underlying biomechanical causes of OA. There is also evidence that increased pain-free activity or walking speed following medication use may actually lead to increased joint loading4<\/sup> and accelerated disease progression5<\/sup> \u2014 a counterintuitive but important consideration for clinicians. <\/p>\n\n\n\n This is where off-loading knee bracing offers something fundamentally different.<\/p>\n\n\n\n A well-designed knee OA brace works by physically altering the forces acting on the knee during movement. The clinical evidence supporting this mechanism is substantial.<\/p>\n\n\n\n Research using highly accurate biplane radiography demonstrated in patients with medial knee OA that wearing a DonJoy OA Defiance brace can induce a significant increase of 0.3 mm in medial compartment dynamic joint space during gait \u2014 roughly a 10% increase during the impact phase of walking. This improvement was consistent from heel strike to terminal stance, meaning the joint is protected throughout the most demanding part of each step.6<\/sup><\/p>\n\n\n\n OA braces have been shown to shift the knee into a more corrected position in patients with varus (bow-legged) knees7,8<\/sup> with the greatest corrective effect occurring at approximately 10% of the gait cycle \u2014 precisely the point of greatest loading.8,9<\/sup> A biomechanical study using the OA Adjuster brace found a difference of 4\u00b0 in varus angle between braced and unbraced conditions, a clinically meaningful correction.9<\/sup><\/p>\n\n\n\n The knee adduction moment \u2014 the force that drives compression on the medial side of the joint \u2014 is a key driver of medial compartment OA progression. OA braces have been shown to reduce peak knee adduction moment by up to 32% during gait,7,9,10<\/sup> with greater reductions achieved when the brace hinge is dialled in further.10<\/sup> The adduction impulse, which accounts for both load and loading time, can be reduced by up to 37%.10<\/sup><\/p>\n\n\n\n Muscle weakness and decreased stability contribute to reduced patient confidence in movement. OA bracing has been shown to improve both perceived and objective knee stability,11,12,13<\/sup> which encourages patients to move more \u2014 breaking the inactivity cycle rather than perpetuating it.<\/p>\n\n\n\n The clinical outcomes for pain relief are striking. In a systematic review by Feehan et al. that included 15 clinical studies, 98.6% of 567 patients with medial knee OA experienced pain relief when fitted with an off-loading brace.14<\/sup> In another study, both custom and off-the-shelf brace options produced significant reductions in pain and stiffness, with custom bracing also showing meaningful improvements in function.7<\/sup> <\/p>\n\n\n\n The effect on daily mobility is equally significant. A patient feedback study by Dries et al. (2022) found that wearing an OA Defiance brace considerably expanded mobility across all patient groups.15<\/sup> The proportion of patients confined to their home environment reduced by 74%, while 42% of brace wearers reported being able to take a long walk or visit a local shop \u2014 activities that had previously been out of reach. This is not a minor quality-of-life improvement; for many patients, it represents a return to independence.<\/p>\n\n\n\n One of the most important questions for both patients and healthcare systems is whether bracing can delay or reduce the need for surgical intervention. The evidence here is encouraging.<\/p>\n\n\n\n A study by Lee et al. (2017) found that patients who wore an off-loading knee brace for two years or more did not require surgery at eight-year follow-up.16<\/sup> Given that the off-loading knee brace is a cost-effective treatment option, its potential as a bridging therapy \u2014 reducing the burden of the treatment gap on both patients and healthcare systems \u2014 is considerable.16,17<\/sup><\/p>\n\n\n\n Modern OA bracing is not a one-size-fits-all solution. Braces are now designed to address a spectrum of OA severity, from early-stage support through to moderate and severe disease. This means clinicians can tailor brace selection to the individual patient’s needs, activity level, and degree of joint involvement.<\/p>\n\n\n\n For patients, the message is equally clear: living with knee OA does not have to mean accepting a steady decline in mobility and independence. For healthcare professionals, the evidence supports placing OA bracing earlier and more consistently in the conservative management pathway \u2014 not as a last resort before surgery, but as an active intervention that can protect the joint, relieve pain, and keep patients moving.<\/p>\n\n\n\n Under the DonJoy\u00ae brand, Enovis\u2122 offers a full portfolio of braces for all severities of knee OA and levels of patient activity.<\/p>\n\n\n\n DonJoy OA GO\u00ae<\/a> helps provide relief from pain and mobility issues caused by mild to moderate knee osteoarthritis.17<\/sup> With a simple twist of a dial, this innovative soft knee brace\u2019s three-point offloading system quickly offloads the affected compartment to help relieve pain and ease movement.<\/p>\n\n\n\n ROAM\u2122 OA<\/a> helps patients say goodbye to knee pain.
