Abstract
Aims: We report the clinical and radiologic outcome after cemented PFC®- TKA at mean follow-up of 9,1 years. Methods: Consecutively all patients with PFC®-TKA between 1989–1993 were investigated. Implant survival was estimated using the method of Kaplan-Meier. Radiologic evaluation was done using the criteria of the American Knee Society. Knee and Function Score of the American Knee Society were used to assess clinical outcome. Hannover Functional Ability Questionaire for Osteoarthritis (FFbH-O) measured limitations in activities of daily living. Visual analogue scale divided pain sensation and a 6-graded scale estimated patient satisfaction. Results: 140 TKA were performed on 122 patients (female:male ratio 3:1, average age 67 years, BMI 27,5). Follow-up rate was 100%. 5-year and 10-year survival was 97% and 92,7%. Radiologic measurements, diagnosis and BMI did not influence survival rate. Clinical results revealed 83 points for knee and 50 points for function score. 88% had a decreased FFbH-O. 57% had no and 33% slight-moderate pain. 72% were extremely or very satisfied. Patient satisfaction correlated well with the knee score, but poorly with the function score. Primary diagnosis (OA/RA) did not influence outcome. Conclusion: PFC®-TKA showed very good survival rates at 5 and 10 years. Knee score was mainly excellent-good, but function score was poor, mainly due to high patient age and associated diseases. Radiologic alignment did not influence outcome.
