[Determination of contact surfaces of the femoropatellar joint with reference to the localization of chondromalacia].

At 13 post-mortem-knees we investigated the patello-femoral contact area in different degrees of function, referring to the localization of chondromalacia. We found that the localization of chondromalacia didn't accord to the contact area in 50% of all cases. Possible other causes are discussed.
