Medial Collateral Ligament Reconstruction for Valgus Instability After Total Knee Arthroplasty

CASE: Medial collateral ligament (MCL) injuries after total knee arthroplasty (TKA) are a rare occurrence. Traditional treatment options include repair and revision to a constrained prosthesis. We present a case of an 80-year-old man who opted for MCL reconstruction in the setting of previous TKA due to late MCL injury from a skiing accident. The presentation, operative techniques, and outcomes of this treatment option are presented. CONCLUSIONS: MCL reconstruction in the setting of TKA can lead to a successful and satisfactory outcome without the need for revision TKA.
