Özet:

 This study aimed to evaluate the clinical, functional, and prosthesis survival outcomes of patients who underwent cruciate-retaining total knee arthroplasty TKA at a single center by a single surgeon, with a minimum follow-up of 13 months. Additionally, the influence of comorbidities and cold sensitivity on mid-term outcomes was investigated. A total of 41 patients 50 knees who underwent TKA for varus-aligned gonarthrosis were retrospectively analyzed. Clinical and functional outcomes were assessed using WOMAC, Clinical and Functional American Knee Society Scores C-AKSS, F-AKSS, SF-12 MCS and PCS, and radiological evaluation was performed using the KSRES scoring system. Patients were grouped based on surgery type unilateral vs. bilateral, etiology, prosthesis brand, total valgus angle TVA, and presence of cold sensitivity. Comparative statistical analyses were conducted among subgroups. Bilateral TKA was associated with significantly higher erythrocyte transfusion requirements p  0.003, worse WOMAC p  0.032, SF-12 MCS p  0.045, and KSRES scores p  0.029 compared to unilateral TKA. No significant differences were found between implant brands in terms of clinical or radiological outcomes p  0.05. Subgroup comparisons based on TVA categories showed no statistically significant differences p  0.05. Patients with cold sensitivity had significantly worse WOMAC p  0.041 and SF-12 MCS p  0.048 scores. Diabetes mellitus or coronary artery disease did not significantly affect KSRES or functional scores p  0.05. Cruciate-retaining TKA is a safe and effective procedure. However, simultaneous bilateral TKA may lead to inferior mid-term outcomes and increased transfusion needs. Based on our findings, unilateral TKA may be more favorable in routine practice, particularly in patients without strong bilateral indications.
