dc.description.abstractObjective: The aim of this study was to evaluate the long-term results of porous-coated, cementless total knee arthroplasty with screw fixation. Methods: This study included 68 knees of 54 patients (43 female, 11 male; mean age: 56.9 years, range 46 to 70 years). Cruciate-retaining cementless total knee prostheses were implanted in all patients diagnosed with primary osteoarthritis. Clinical, functional and radiological evaluations were performed according to the Knee Society's Knee Scoring System (KSS). Prosthesis survival was analyzed using Kaplan-Meier curves. Mean follow-up time was 9.2 (range: 8 to 12) years. Results: Preoperative mean knee and function scores were 42.3 (range: 32 to 61) and 39.1 (range: 35 to 66), respectively, while they were 88.6 (range: 54 to 96) and 82.8 (range: 50 to 100), respectively at the final follow-up (p<0.05). Mean preoperative knee flexion was 98 degrees (range: 80 degrees to 110 degrees) and 112 degrees (range: 85 degrees to 130 degrees) at the final follow-up (p<0.05). Preoperative and postoperative mean alignments were 9.2 degrees varus and 5.4 degrees valgus, respectively. Revisions were performed due to aseptic loosening of the tibial component in one patient, periprosthetic fracture in one and dislocation of the patella in one. Two superficial infections (3%) were observed. There was no osteolysis around the screws during the follow-up period. The overall rate of implant survival was 95.6% (range: 91.56% to 99.60%; 95% CI) at 12 years. Conclusion: Long-term outcomes of porous-coated, cementless total knee arthroplasty with screw fixation were successful in terms of clinical and radiological evaluation and yielded a high survival rate.en_US
