Abstract
Objective To observe the effectiveness of tendon allograft in the treatment of old knee medial collateral ligament in‐jury .Methods Thirty‐two cases of old knee medial collateral ligament injury were treated .Tendon allograft was used to reconstruct old injury of knee medial collateral ligament and was fixed in bone with absorbable screws in operation .Results All incisions were healed by first intention .No infection ,deep vein thrombosis ,or other postoperative complications occurred .Thirty two cases were followed up fro 12 to 58 months with an average of 30 months .At 3 months after operation ,the knee X ray films of valgus stress position showed the medial joint space differences between both knees were less than 1 mm .According to the Lysholm Scale score average (92 .3 ± 4 .2) ,the results were excellent in 20 cases ,good in 11 cases ,and fair in 1 case with excellent rate of 97% at last follow up ,the knee scores were (42 .5 ± 5 .3) before operation and (92 .3 ± 4 .2) after operation ,showed significant difference(P<0 .05) .Conclusion Anatomical reconstruction of old injury of knee medial collateral ligament with tendon allograft is all‐sided and the fixation method was solid .The operation is easy to operate and achieves better effectiveness .关键词
