Abstract：Objective To evaluate clinical outcomes of arthroscopic ending reconstruction of posterior root tear of the lateral meniscus in the knee.Methods From March 2010 to March 2014, 18 cases of posterior root tear of the lateral meniscus in the knee underwent arthroscopic ending reconstruction. Seven cases were of simple tear of the root, 11 were of combined radial tear of the posterior lateral complex. Fifteen cases combined with anterior cruciate ligament ( ACL ) injury and 3 cases with multiple ligaments injury underwent one-stage reconstruction. Lysholm score, IKDC score and visual analog scale ( VAS ) were applied to evaluate knee functions preoperatively and postoperatively. MRI and arthroscopic exploration of patients with follow-up were used to evaluate the healing of the lateral meniscus tear.Results The mean follow-up period was 20.2 months ( range: 6-41 months ). Postoperatively, the Lysholm knee score was 90.0±4.5, IKDC knee score was 84.6±3.2, VAS knee score was 0.7±0.9. Differences were statistically significant (P<0.001 ). Eighteen cases received MRI examination 1 year postoperatively: 17 cases ( healing rate: 94.4% ) showed completely healing of the meniscus and 18 cases ( healing rate: 100% ) with cruciate ligaments injury were conifrmed completely healing of the lateral meniscus by arthroscopic exploration.Conclusions Arthroscopic ending reconstruction is a good option in the treatment of posterior root tears of the lateral meniscus in the knee with the advantage of complete internal suture and reconstruction. It can receive satisfactory knee functions.
