Radiological and clinical effect of prosthesis design in varus knees?

Purpose: The aim of the study is to investigate the efficacy of the prosthesis design used in total knee arthroplasty in patients with varus malalignment. Methods: After exclusion criteria we classified 90 patients underwent total knee arthroplasty according to prosthesis used into two groups: posterior cruciate ligament substituting and retaining. Mean follow up period was 25-98 months. We evaluated pre-operative and postoperative radiological and as well as clinical parameters such as pain, knee function, flexion deformity. Results: We found statistically significant difference in both groups in terms of deformity correction (p = 0.000). Conclusion: Prosthesis design affects radiological outcomes in varus knees.
