Abstract

Purpose: The aim of this study is to investigate retrospectively the midterm clinical and radiological outcomes of total knee arthroplasty (TKA) which were performed in our clinic.
Method: Thirty-one (27 women, 4 men) of 54 patients were included in the study. At midterm, a minimum of 4 years (49-135 months) after surgery, Knee Society scores (KSSs), Knee Society Functional scores (KSFSs), range of motion (ROM), and radiographic results of 36 knees of 31 patients were assessed and reported in this study.
Results: The preoperative mean knee score was 60.8 (37-78), while after the surgery it was 89.7 (56-100), respectively. In terms of knee score, 30 knees (83.3%) had excellent, 5 (13.8%) had good and 1 (2.7%) had poor results. The average preoperative functional score was 35.6 (15-60), while average postoperative score was 71.5 (45-95), respectively. In terms of functional knee scores, 9 (25%) were excellent, 11 (30.5%) were good, 11 (30.5%) were moderate, and 5 (13.9%) were poor. The range of motion (ROM) of the knees and stability were significantly increased.
Conclusion: Osteoarthritis is a disease that limits severely the quality of life and daily functioning of patients. With the appropriate patient selection, adequate preoperative preparation, appropriate prosthesis selection and careful surgical technique, the treatment of knee osteoarthritis in patients with total knee arthroplasty (TKA) constitutes a highly effective treatment option.
