Objective To evaluate the clinical outcomes of repairing medial meniscus tears using pie-crusting of the superficial medial collateral ligament(MCL)under the arthroscopy. Methods From March2014 to October 2014,37 consecutive cases were included in this study. Among all of the patients,23 were male,14 were female,with an average age of 36.7±9.2 years. Six of the 37 patients were only ofmedial meniscus tears,while the other 31 were combined with anterior cruciate ligament(ACL)injuries.Pie-crusting technique of MCL was used and the suturing of meniscus tears was performed from the in-side to outside. All patients were followed up about their subjective symptoms,MCL stability and wheth-er they had joint interlocking,pain in the medial joint space and pressing pain. MRI was conducted toevaluate the healing status of the meniscus. Results The mean follow-up period was 26.1±4.4 months.For all of the patients,there was no instability in the medial compartment of the knee joints. For 31 patients receiving ACL reconstruction and medial meniscus repair,the Lachman test of the injured kneeafter the surgeries indicated a mean side to side difference of 1.3±0.7 mm,with significant improve-ment compared with preoperative results(7.1±2.2 mm)(P0.01). Three patients complained tendernessat the medial side of the knee without locking. It was found from MRI the healing rate of the menis-cus was 81.1%. Conclusion The healing rate after arthroscopic repair of the medial meniscus tears was 81.1% with a mean follow-up period of 26.1 months. Pie-crusting in superficial MCL helped toenlarge the medial compartment of the knee and promote operative efficiency during the surgeries.There was no unstable medial compartment of the knee joints after the surgeries.
