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\u2019s Knee Scoring System (KSS). Prosthesis survival was analyzed using Kaplan-Meier curves. Mean follow-up time was 9.2 (range: 8 to 12) years. \\r\\nResults: 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&lt;0.05). Mean preoperative knee flexion was 98\u00b0 (range: 80\u00b0 to 110\u00b0) and 112\u00b0 (range: 85\u00b0 to 130\u00b0) at the final follow-up (p&lt;0.05). Preoperative and postoperative mean alignments were 9.2\u00b0 varus and 5.4\u00b0 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. \\r\\nConclusion: 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.\n\n\n\u00d6zet\n\nAma\u00e7: \u00c7al\u0131\u015fmam\u0131zda poroz kapl\u0131, vidal\u0131 \u00e7imentosuz total diz artroplastisi (TDA) uygulamalar\u0131n\u0131n uzun d\u00f6nem sonu\u00e7lar\u0131n\u0131 de\u011ferlendirmeyi ama\u00e7lad\u0131k. \\r\\n\u00c7al\u0131\u015fma plan\u0131: \u00c7al\u0131\u015fma 54 hastan\u0131n (43 kad\u0131n, 11 erkek; ortalama ya\u015f: 56.9, da\u011f\u0131l\u0131m: 46-70) 68 dizi ile yap\u0131ld\u0131.
