Role of surgery in the management of lesions of the medial collateral ligament of the ankle

Orthop Traumatol Surg Res. 2020 Dec;106(8S):S195-S199. doi: 10.1016/j.otsr.2020.08.005. Epub 2020 Sep 6.


Medial ankle instability is likely underestimated. Three types of medial collateral ligament (MCL) lesion exist: isolated lesions, in case of valgus sprain in external rotation; lesions associated with chronic lateral instability, in case of rotational instability; and lesions associated with medial insufficiency and valgus flat-foot. Diagnostic confirmation and treatment of MCL lesions, isolated or associated with chronic lateral instability, by ligament suture is at present largely arthroscopic. Chronic MCL lesions with valgus flat-foot are probably irreversible: ligament reconstruction is unreliable, and bone surgery (osteotomy, fusion) is required.
