Medial Patellofemoral Ligament Reconstruction Following Total Knee Arthroplasty: A Case Report

This is the authors' abstract. We don't add key points for this paper.

Patella instability is a rare but serious complication seen following total knee arthroplasty. The typical cause of patella instability in this setting is malpositioned components. While the mainstay of treatment is recognizing and correcting any malpositioning of the components, continued instability can remain and be a difficult problem to treat. Medial patellofemoral ligament (MPFL) reconstruction can be a helpful adjunct for the surgeon when faced with cases of continued instability. In this case report, we describe the successful use of MPFL reconstruction in conjunction with component revision for the treatment of postarthroplasty patella instability.
