Radiological and clinical effect of prosthesis design in varus knees?

PurposeThe aim of the study is to investigate the efficacy of the prosthesis design used in total knee arthroplasty in patients with varus malalignment.MethodsAfter 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 preoperative and postoperative radiological and as well as clinical parameters such as pain, knee function, flexion deformity.ResultsWe found statistically significant difference in both groups in terms of deformity correction (p = 0.000).ConclusionProsthesis design affects radiological outcomes in varus knees.
