Atraumatic Fracture of the Medial Femoral Condyle of a Total Knee Arthroplasty.

The fracture of the femoral component is a rare complication of a total knee arthroplasty (TKA). This article presents a case in which a 70-year-old man underwent a left press-fit Advance Medial-Pivot Knee System TKA (MicroPort Orthopedics, Arlington, TN) in 2000. Twenty years later, he experienced a nontraumatic onset of knee pain after standing up from a lunge position.
