Reconstruction by biceps tendon rerouting for posterolateral rotatory instability of the knee: Modification of the...

We present a biceps rerouting technique for posterolateral rotatory instability using a modification of the biceps femoris tendon tenodesis of Clancy. The distinguishing features of this technique are the approach to the lateral femoral epicondyle through the interval between the iliotibial band and biceps femoris muscle, and fixation of the transferred biceps tendon at the isometric point. Reconstruction for posterolateral rotatory instability by modified biceps tendon rerouting can result in objectively and functionally acceptable knee function.
