title: Radiological and clinical effect of prosthesis design in varus knees?
abstract: OBJECTIVE
  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 preoperative 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).
  
  
  CONCLUSIONS
  Prosthesis design affects radiological outcomes in varus knees.
