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.
