Percutaneous MCL reconstruction technique in acute anterior medial knee instability using cadaveric grafts

PURPOSE: There are several alternatives described for the treatment of acute injuries of the anterior cruciate ligament (ACL ) and the medial collateral ligament (MCL) of the knee. We present the result of the combined ACL reconstruction and MCL in the same surgical procedure using only percutaneous cadaveric graft in the reconstruction of the MCL ligament. METHODS: We retrospectively analyzed 30 patients with acute anterior and medial knee instability surgically treated between August 2007 and September 2013. 27 men and 3 women , mean age 30.53 years (range 18-46 ) The level of pre and post surgical activity was determined by the Tegner score , while the function was evaluated using the Lysholm score and IKDC grade RESULTS: The average follow-up was 43 months (range 12-84 months). The mean Lysholm score was 91 (R, 61-100 ) . Only 19 of 30 (63.3 %) patients returned and kept the pre -injury level sports ; 26 patients IKDC : A (normal knee ), 3 patients IKDC : B (slightly abnormal knee ) and 1 patient IKDC C ( Knee abnormal) with limitation of 15 degrees of extension that had to be reoperated. CONCLUSION: The use of cadaveric tendons for reconstruction of MCL in combination with ACL reconstruction surgeries resulted in less postoperative pain, good functional results, and a high rate of return to competitive sport. The result of this study shows that the percutaneous reconstruction of LCM cadaveric graft is a viable option.
