Supervised exercise therapy is more effective at reducing pain and improving function than usual care for patients with severe knee pain,according to a new study. The study has been published online in the ‘British Medical Journal’. Patellofemoral pain syndrome is a condition in which pain occurs at the front of the knee during or after exercise and is a common reason to visit the doctor. Women are more likely to be affected than men,and symptoms usually start during adolescence when participation in sporting activities is high. To reach the conclusion,researchers based in the Netherlands investigated the effectiveness of supervised exercise therapy compared with usual care in 131 patients aged between 14 and 40 years with patellofemoral pain syndrome. After analyses,the boffins found that a higher proportion of patients in the exercise group than in the control group reported recovery.
