To investigate whether the use of valgus knee brace is useful for patients with medial knee osteoarthritis.
Osteoarthritis of the knee is the commonest type of arthritis affecting both the middle age and geriatric population, which poses a huge burden to our in-patient and out-patient orthopaedic services. Conservative treatment like physiotherapy and analgesic provide temporary symptomatic relief. Surgical treatment like high tibial osteotomy and knee arthroplasty are not without major potential surgical risks and implant-related complications. Orthotic treatment can theoretically alter the loading to the knee joint and help to reduce the symptoms and disease progression. Small scale biomechanical studies have demonstrated such effects with the use of valgus knee brace (2-4). Though prospective clinical outcome studies on Chinese patients in our locality are lacking. Valgus knee brace is a non-pharmaceutical, non-invasive option for knee pain. Using a three-point leverage the unloader brace is to shift the stress away from the arthritic area to the normal portion of the knee, maintains good alignment and stability and thus provides significant pain relief during daily activities. It has been commonly used as a first line management option in other countries. Our aim is to perform a prospective randomized study to look at the difference in outcome measures in osteoarthritic patients with the use of valgus knee brace, on top of the usual regime of conservative treatment.
