Medial collateral ligament reconstruction during TKA: a new approach and surgical technique.

Medial collateral ligament (MCL) injuries during total knee arthroplasty are rare but severe complications. They can be treated conservatively, by increasing prosthetic constraint, by using a thicker polyethylene insert, or by directly suturing the ligament. A prosthesis is successful to the extent that it ensures long-term knee stability. We describe our surgical approach to the restoration of knee joint stability in MCL deficiency: a reconstructive technique using the semitendinosus tendon.
