ABSTRACT
Objective To introduce the method of knee posterolateral complex reconstruction with the long head of biceps femoris tendon, and to evaluate the short-term outcomes. Methods Anatomic reconstruction of the chronic posterolateral complex injury of knee joint in 23 cases, were performed with the long head of the biceps femoris tendon from February 2001 to November 2002. All of the patients complained of knee instability with abnormal gait, all of which were associated with other knee ligament injury. With retention of the distal attachment or insertion of the long head of the biceps femoris tendon, a distally pedicled tendon slip was made 8-10 mm of width and 16-18 cm of length. Then the tendon slip was divided longitudinally into halves. The posterior half was folded to reconstruct the popliteofibular ligament and popliteal tendon, with the femoral insertion at the anatomical attachment site of the popliteal tendon, the free end fixed into the tunnel at the posterolateral corner of the tibial plateau. The anterior half was folded to reconstruct the lateral collateral ligament, with the femoral insertion at the anatomical attachment site of the lateral collateral ligament, and the free end fixed into the tunnel or sutured to the fibular head. Results The posterolateral stability of the knee was evaluated in more than 6 months follow-up, mainly through examination of knee varus instability and leg external rotation range. 6 months after operation, there was no varus knee instability in full extension. At 30? flexion, one-grade varus instability was found in 2, but with firm endpoint, no varus instability was found in other cases; external rotation increased in 2, remained the same in 16, and decreased in 5 compared with the healthy side. One year after operation, the stability of the posterolateral corner of the knee had no change compared with that of the 6 months examination. Conclusion Simultaneous reconstruction of knee lateral collateral ligament, popliteofibular ligament, and popliteal tendon with the long head of biceps femoris tendon is effective to restore posterolateral stability of the knee joint.
