Das femoropatelläre Schmerzsyndrom.Konservative und operative Therapie im Longzeitvergleich (10-20 Jahre) und ihre therapeutischen Konsequenzen.

Long term results in conservative and operative treatment (10-20 years) and their therapeutical consequences. There are many factors involved in the aetiology and pathogenesis of the patellofemoral pain syndrome. Increased pressure over the lateral facet with or without reduced pressure over the medial of the patella resulting from lateral positioning of the patella and different anatomical variants not of the patella, but of the condyles must be considered as well functional variants in the muscular and ligamentous system. Overviewing the literature we compare the long term results of operative versus conservative treatment. 75 patients, treated by the method of Maquet-Roux, and 150 patients, treated conservatively, showed satisfactory results in 72%, a Lysholm Score of 90.8 in the "Maquet"-group, but 89.9 points in the "conservative"-group with a follow-up of 23 years. In the "conservative"-group 52% had no signs of arthrosis, in the "Maquet"-group there are only 30% without signs of arthrosis. The X-ray examination had mostly shown a further stage of arthrosis not only in the femoropatellar, but also in the femorotibial compartment, especially in the "Maquet"-group.
