Long-term results of cemented, posterior cruciate ligament-retaining total knee arthroplasty in osteoarthritis.
Two hundred fifty-four total knee arthroplasties (TKAs) in 223 patients (82 men and 141 women) with osteoarthritis were reviewed. Average patient age at surgery was 68 years (range: 37-90 years). No patient was lost to follow-up. Average follow-up was 16.8 years (range: 15.2-23.2 years). Preoperatively, 175 (69%) knees had a varus deformity. The posterior cruciate ligament (PCL) was retained in all 254 knees, and all prostheses were cemented. Clinically, 91% of knees were rated as excellent; however, functionally, only 23% of knees were rated as excellent. There were 13 (5%) complications. Revision was performed in 10 (4%) knees. Survivorship analysis showed average implant survival for all revisions was 96.3% (range: 91.9%-98.3%) at 15 years and 82% (range: 60%-92.6%) at 23 years. Long-term results of cemented, PCL-retaining TKA for osteoarthritis are excellent in terms of improved clinical function and pain relief.
