Exercise for treating patellofemoral pain syndrome (PFPS)
31 heterogeneous trials including 1690 participants with PFPS were included in this review Seven outcome measures were chosen to summaridse the available evidence: pain during activity (short-term: ≤ 3 months); usual pain (short-term); pain during activity (long-term: > 3 months); usual pain (long-term); functional ability (short-term); functional ability (long-term); and recovery (long-term). Litterature until June 2014 was included in the review.
The evidence of exercise therapy versus control was in favour of exercise therapy being clinically important in reducing pain during activity and usual pain,improvement in functional abilityin the short term and long term and greater numbers reporting recovery from their symptoms in the long term.Evidence of hip plus knee exercises may provide a clinically important reduction in pain during activity and usual pain in the short term and pain during activity in the long term, when compared with knee exercises only.
Due to the low quaility of studies the authors conclude that further randomised trials are warranted, including research aiming at identifing priority questions and attaining agreement and, where practical, standardisation regarding diagnostic criteria and measurement of outcome.
