Patellofemoral pain syndromes: a comprehensive and conservative approach.

Among 7,785 patients examined with knee problems, 370 were diagnosed with patellofemoral pain syndromes. Examination and treatment were performed using a systematic approach. The patients were placed on a conservative program consisting of a four-stage progression, with the goal of relieving symptoms and returning to full activity. The results of this approach showed that 77% recovered. to a satisfactory level and 23% were unsatisfactory and underwent surgical procedures. J Orthop Sports Phys Ther 1981;2(3):108-116.
