Introduction: In cases of multiple ligament injury or severe medial collateral ligament (MCL) lesion, nonoperative treatment of the MCL lesion may lead to chronic valgus instability or rotatory instability.
Methods: From May 2012 to December 2014, 16 patients with grade 3 or 4 medial instability were treated with MCL reconstruction. Median age was 36 years. Three patients underwent isolated MCL reconstructions, 14 had combined MCL and anterior cruciate ligament (ACL) reconstruction. All patients had reconstruction of the medial collateral using ipsilateral semitendinosus autografts. All patients were available for follow-up more than 12 months postoperatively and were examined by an independent observer using objective International Knee Documentation Committee (IKDC) measures.
Results: At follow-up, medial stability according to the IKDC score showed 98% normal or nearly normal (grade A or B), and for overall IKDC score, patients improved from 5% with grade A or B preoperatively to 79% with grade A or B at follow-up. There were 91% who were satisfied or very satisfied with the result.
Conclusion: Acceptable clinical results with the MCL reconstruction technique were achieved in patients suffering from chronic valgus instability.
