Patellar Instability

Key Concepts

  • Patellar instability is a common cause of anterior knee pain and stiffness following total knee arthroplasty (TKA).

  • The most common underlying etiology is malrotation of the femoral, tibial, or both components.

  • Revision surgery to address patellar instability should address all malpositioned components and often requires both femoral and tibial revision.

Sterile Instruments and Implants

  • Revision TKA instrumentation and implants.
