Simultaneous surgical management of chronic grade-2 valgus instability of the knee and anterior cruciate ligament deficiency in athletes.

We report on 22 patients with chronic grade-2 valgus laxity of the knee combined with chronic anterior cruciate ligament (ACL) insufficiency, in whom the two lesions were addressed at the same surgical setting. At a minimum follow-up of 24 months, clinical and functional variables had improved significantly (P < 0.001), and 20 of the 22 patients (91%) had returned to sport at pre-injury level. There were no operative complications in this series. In selected athletes with chronic symptomatic valgus laxity of the knee combined with ACL insufficiency, surgical repair of the MCL in association with ACL reconstruction is a suitable and reliable option to restore knee stability and allow return to pre-injury activity level
