Abstract
ObjectiveBraces 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...
Highlights
We studied one control structural outcome we hypothesised would not change with treatment, tibiofemoral bone marrow lesions (BMLs) volume, which we determined by taking the whole knee’s BML volume and subtracting the PF BML volume
In this trial, we found that a PF brace reduced pain in patients with PF OA over a 6-week period
This brace was associated with a reduced volume of PF BMLs compared with the control
Summary
The use of MRI in knee OA studies has revealed structural features that may be treatment targets. We performed a 6-week randomised controlled trial testing the efficacy of a patellar brace on knee pain and BML volumes as tracked by serial knee MRIs. Because there is no evidence that PF braces affect tibiofemoral joint BMLs which are caused by varus/valgus malalignment, we hypothesised that tibiofemoral BMLs would not change with PF brace use. METHODS Overview We carried out a 6-week randomised trial of treatment with a patellar brace for patients with painful PF OA.
