Orthoses for osteoarthritis represent splints, taping, sleeves, unloading knee braces and insoles. This review of the effectiveness of these orthoses involved a search for articles published up to 2015 in MEDLINE via PubMed, with a focus on Osteoarthritis Research Society International, American College of Rheumatology and European League Against Rheumatology international recommendations. Evidence for splinting effectiveness in patients with thumb-base osteoarthritis is now provided. Splints for thumb-base osteoarthritis decrease pain and functional disability. Weaker evidence was found for knee bracing, including taping, sleeves and unloading braces. Low rate of observance and safety results should be considered before using current unloading knee braces for knee osteoarthritis. For insoles, data remain controversial. Orthoses for interphalangeal or hip osteoarthritis have not been investigated in a randomized trial. Regardless, if indicated in daily clinical practice, bracing must be checked by a healthcare professional to insure the suitability of the device. Patients using bracing must be educated. Patient education should include knowledge of the aims and modalities of the treatment as well as knowledge of potential side effects. Patients should be encouraged to contact the therapist if adjustment is needed, with poor tolerance or with questions about the device.
