| Background Fixed-bearing primary total knee replacement is a well-established method of treatment for advanced arthritic knee joint. Aim of the study This study evaluated the clinical, functional, and radiological outcomes after the use of fixedbearing total knee arthroplasty in cases of primary total knee replacement. Patients and method This prospective study was conducted on 14 patients (six male and eight female) who attended Suez Canal University Hospitals between January 2012 and January 2013, and the mean age was 60 years (range 50–72 years) at the time of surgery. The patients included in the study had advanced unilateral knee osteoarthritis with severe pain and functional disability with failure of conservative measures. Preoperative clinical and radiological evaluation was carried out and the knee society clinical and functional rating system (KSS) was used to evaluate the patients preoperatively and postoperatively at 1-year follow-up. The scoring system combines a relatively objective knee score that is based on the clinical parameters and a functional score based on how patients perceive their knee function in relation to specific activities. Radiological evaluation was carried out to determine the alignment of the knee and the femoral and tibial component positions. Results There was significant difference between preoperative and postoperative clinical and functional scores. The mean postoperative clinical assessment score for pain was 44.9, for range of motion it was 115.9, and for stability it was 23.5. Postoperative mean knee society clinical assessment score was 90.7 and the mean functional assessment score for knee function was 87.5. According to the knee society clinical and functional score, 85% of patients had excellent results and 15% of patients had good results. As regards radiological results, all knees were well-aligned at 1 year postoperatively and no periprosthetic loosening or radiolucent line around either component was found. Conclusion Primary total knee arthroplasty using fixed-bearing prosthesis is an effective procedure with good clinical and functional results and early mobilization. | ||||
