The patellofemoral joint in total condylar knee arthroplasty. Pros and cons based on five- to ten-year follow-up observations.
In this report, 100 knees in 77 patients, with an average age of 65, were followed for a period between five and 10 years. Rheumatoid arthritis was the diagnosis in 43 patients and osteoarthritis in 34 patients. The majority had varus, valgus, and biplane deformities. ⋯ No dislocations occurred, but 14 patellae showed tilt on skyline view roentgenograms, indicating a tight lateral retinaculum. In view of the good to excellent results achieved in the majority of patients, and the low morbidity associated with replacement, it is recommended that the patellofemoral joint be replaced in the course of total knee arthroplasty. When careful attention is paid to technical details, this procedure improves the quality of the arthroplasty.
