Influence of femur condylus dysplasia on development of mediopatellar synovial fold hypertrophy

Abstract

Among all anatomic folds of the knee joint, mediopatellar synovial fold has the highest rate of pathological changes that also have influence on adjacent anatomical structures. Presence rate of mediopatellar fold is 4650% according to cadaveric data and 1880% according to data acquired in an arthroscopic way. In this work, we studied the possible link between femur condylus dysplasia and forming of the mediopatellar fold. The MRI study was done to 116 patients divided into two equal groups (58 patients in each). The main group (group I) included patients with detected femur condylus dysplasia, the control group (group II) patients without detected femur condylus dysplasia. Our results suggest that in the main group the mediopatellar fold is detected in 53 patients (91,4% of all cases), in the control group in 4 patients (6,9% of all cases). The results support our hypothesis that while performing the arthroscopic treatment of the patologically thickened mediopatellar synovial fold, the dysplasia of femur condylus must be taken into account.
