Arthroscopically assisted combined posterior cruciate ligament/posterior lateral complex reconstruction.

Abstract

This article presents the minimum 2-year results (range, 24 to 54 months) of 21 arthroscopically assisted posterior cruciate ligament/posterior lateral complex (PCL/PLC) reconstructions, evaluated preoperatively and postoperatively using the Tegner, Lysholm, and Hospital for Special Surgery knee ligament rating scales, and the KT 1000 knee ligament arthrometer (Medmetric Corp., San Diego, CA, U.S.A.). There were 15 male and 6 female patients; 6 right and 15 left; and 10 acute and 11 chronic knee injuries. All injuries were PCL/PLC knee ligament injuries. PCLs were reconstructed using allograft Achilles tendon, or autograft patellar tendon. Posterior lateral instability was successfully treated with long head of biceps femoris tendon tenodesis. Tegner, Lysholm, and Hospital for Special Surgery knee ligament rating scales significantly improved preoperatively to postoperatively (P = .0001). PCL screen and corrected posterior KT 1,000 measurements improved from preoperative to postoperative status (P = .0009, and P = .0096, respectively).
