Patellar tracking patterns were studied in 20 cadaver knees. The predominant pattern (Type 1) found in 17 knees included medial shift and medial tilt of the patella with respect to the tibial tubercle during extension of the knee. The remaining three knees (Type 2) showed a tendency toward lateral shift and tilt. Release of the lateral retinaculum had no effect on patellar tracking in most knees, while release of the medial retinaculum produced abnormal tracking in many Type 1 knees and all Type 2 knees. The "proximal realignment" (medial imbrication-lateral release) procedure increased the tendency of the patella to tilt and shift medially during extension.
对20具尸体膝关节的髌股轨迹模式进行了研究。在17个膝关节中发现的主要模式（1型）包括在膝关节伸展过程中髌骨相对于胫骨结节的内侧移位和内侧倾斜。其余3个膝关节（2型）表现出外侧移位和倾斜的趋势。在大多数膝关节中，外侧支持带松解对髌股轨迹没有影响，而内侧支持带松解在许多1型膝关节和所有2型膝关节中产生了异常轨迹。“近端重新排列”（内侧重叠-外侧松解）手术增加了髌骨在伸展过程中向内侧倾斜和移位的趋势。
