Abstract

Common complications after unicompartmental knee arthroplasty include infection, aseptic loosening, polyethylene wear, and progression of another compartmental arthritis. Complications caused by extruded cement and loose cement body are very rare, and have not been reported in Korea. This paper reports a case of femoral cartilage injury of the lateral compartment caused by a loose cement body after unicompartmental knee arthroplasty. The loose cement body was removed successfully by arthroscopic surgery.
