Spontaneous late dislocation of the high flexion tibial insert after Genesis II total knee arthroplasty. A case report.
We present the first case of late spontaneous dislocation of a high flexion polyethylene insert after Genesis II total knee arthroplasty. Dislocation of the fixed insert occurred at 14 months post surgery while walking down a steep aircraft staircase. The total knee arthroplasty had been uneventful till that moment. The clinical presentation, possible causes and management are discussed. A surgical error, failure to remove a posterior femoral osteophyte, seems the most probable cause for the late insert dislocation in our case.
