Unloader Braces for Medial Compartment Knee Osteoarthritis

BACKGROUND For persons with unicompartment knee osteoarthritis (OA), off-unloader braces are a mechanical intervention designed to reduce pain, improve physical function, and possibly slow disease progression. Pain relief is thought to be mediated by distracting the involved compartment via external varus or valgus forces applied to the knee. In so doing, tibiofemoral alignment is improved, and...

A randomised trial of a brace for patellofemoral osteoarthritis targeting knee pain and bone marrow lesions

OBJECTIVE Braces used to treat (PF) osteoarthritis (OA) may reduce contact stress across the PF joint. We hypothesised that in PF OA, braces would decrease knee pain and shrink PF bone marrow lesions (BMLs). METHODS Eligible subjects had painful PF OA. Subjects were randomly allocated to brace or no brace for 6 weeks. Knee MRIs were acquired at baseline and 6 weeks. We measured BMLs on post-c...

Long-term results of an unloader brace in patients with unicompartmental knee osteoarthritis.

Previously, we reported a prospective study of 30 patients with unicompartmental osteoarthritis of the knee treated nonoperatively with an unloader brace and average follow-up of 2.7 years. Although the initial study suggested short-term benefit according to pain and function measures, the objective of the current study was to evaluate these same patients via telephone questionnaire to determin...

The effects of a brace for patellofemoral osteoarthritis targeting knee pain and bone marrow lesions

We read with deep interest the article by Callaghan et al related to the efficacy of patellar brace in patients with patellofemoral (PF) osteoarthritis (OA) targeting knee pain and bone marrow lesions (BMLs). To our best knowledge, patellar brace in the management of PF disorders, including PF arthritis, was first introduced in 1981. Since then only a few studies have examined the effects of pa...

Analysis of biomechanical effectiveness of valgus-inducing knee brace for osteoarthritis of knee.

The biomechanical effectiveness of a valgus-inducing knee brace was investigated for 16 patients with knee osteoarthritis (mean +/- standard deviation age 56 +/- 10 yr, height 172 +/- 9 cm, mass 83 +/- 7 kg, body mass index 27.6 +/- 4.5 kg/m(2)). At the time of investigation, all subjects had been wearing the brace for at least 4 weeks. In addition to conducting standard gait analysis, we calcu...
