The press-fit condylar total knee system: 8- to 10-year results with a posterior cruciate-retaining design.

A total of 108 consecutive Press-Fit Condylar total knee arthroplasties were performed in 94 patients. All patients had implantation with a cemented posterior cruciate-retaining design, which included resurfacing of the patella. Mean age at surgery was 70 years (range, 35-87 years). Patients were followed for a mean of 9 years (range, 8-10 years) with follow-up for all surviving patients. The average postoperative functional knee score was 96 points. Nonprogressive radiolucent lines were present in 59%. One patellar component was radiographically loose. Five knees underwent revision procedures, none for aseptic loosening. Survivorship was 93.4% at 9 years with revision for any reason as the endpoint and 98.7% with aseptic loosening as the endpoint. This knee arthroplasty shows excellent results at 8 to 10 years with no patients lost to follow-up.
