Abstract

[Indexed for MEDLINE] 11. Orthopade. 2005 Jul;34(7):668-76. doi: 10.1007/s00132-005-0818-5. [Patellofemoral pain syndrome]. [Article in German] Bohnsack M(1), Börner C, Rühmann O, Wirth CJ. Author information: (1)Orthopädische Klinik der Medizinischen Hochschule Hannover, Klinik II im Annastift. bohnsack@annastift.de The patellofemoral pain syndrome is of high socioeconomic relevance as it most frequently occurs in young working patients. As its etiology is often unknown there is no standard treatment protocol. Several studies analyzed the different causes of patellofemoral pain and their different therapies. Static problems (pes planovalgus, instabilities, leg length differences) or chronic overuse of the knee extensor mechanism have to be identified and treated. After exclusion of intra-articular pathologies, the treatment of patellofemoral pain syndrome begins with conservative management. Stretching of the flexor and extensor muscles and training of the quadriceps muscle are the main approaches. If conservative treatment fails and patellofemoral pain persists, there are several surgical procedures for realignment of the patella in the trochlear groove and reduction of the patellofemoral pressure. Overweight patients exhibit chronic mechanical overuse of the patellofemoral joint. This leads to a higher rate of cartilage degeneration and problems at the inserting tendons and stabilizing tissues. DOI: 10.1007/s00132-005-0818-5
