Manojlovic D, et al. - A systematic review and meta-analysis were conducted to compare the effects of Hip&Knee, Hip-only, and Knee-only exercise programs on pain relief, muscle strength, and functional performance in patients with patellofemoral pain (PFP). Researchers carried out literature searches of PubMed, PEDro and CINAHL databases including 21 studies in the final descriptive review, thirteen of which were included in the meta-analysis. The results showed that in patients with PFP, Hip&Knee exercise programs seem to decrease pain and improve function more than other exercise programs and could be used as a primary rehabilitation approach. Nevertheless, the difference between the subgroups in most outcome measures implies that Hip&Knee exercise programs are no more effective than Hip-only exercise programs.
