title: Surgical technique for treatment of concomitant grade II MCL lesion in patients with ACL rupture.
abstract: Combined lesions of anterior cruciate ligament (ACL) and medial collateral ligament (MCL) are frequent in athletes. While surgical treatment of ACL injury is mandatory treatment regime of concomitant grade II MCL lesions remains unclear with tendency to surgical intervention. Standardized surgical technique is lacking. Present study wants to introduce surgical technique for treatment of concomitant grade II MCL lesion and report short term outcome results. 5 Patients with acute ACL rupture and grade II MCL-lesion were included. All patients received surgical treatment of concomitant MCL lesion by distinct surgical technique and ACL reconstruction. We evaluated valgus instability, anterior instability and range of motion (ROM) according to international knee documentation commitee (IKDC) and Lysholm‑Score both preoperative and after 6, 16 weeks and 9 months postoperative. All Patients showed excellent clinical results at final follow-up. Valgus and anterior stability could be restored in all patients. 1 patient (20%) lost 15° in flexion of ROM at final follow up. However in all 5 patients (100%) the findings were graded as normal or nearly nor-mal according to IKDC knee examination form. Lysholm-Score averaged 94,6. Therefore presented surgical technique improved both, valgus and anterior stability, and led to excellent short term results at final follow up.
