Operative and nonoperative treatments of medial collateral ligament rupture were not different in combined medial collateral and anterior cruciate ligament rupture.

Intervention: All patients had ACL reconstruction within 4 to 23 days. On the day of surgery, patients were allocated to operative (n = 23) or nonoperative (n = 24) treatment of MCL injuries. ACL reconstruction was done with use of the single-incision transtibial technique and a bone-patellar tendonbone autograft. MCL structures were repaired with suture anchors or were sutured through bone tunnels and completed with direct suturing. The posterior oblique ligament or superficial MCL were not reefed, and the range of motion was checked before closing.
