Breakage of the patellar component of a kinematic total knee arthroplasty. A case report.
Most complications of total knee arthroplasty have been of a general nature (ie, infection, pulmonary embolus, nerve palsy), or have involved either the tibial or femoral components. Occasionally, problems involving the patellar implant have been described including subluxation/dislocation, soft tissue impingement and patellar fractures. This article provides the first description of a new complication, fracture of the patellar implant at the stem-button interface.
