title: Clinical comparison of valgus and varus deformities in primary total knee arthroplasty following midvastus approach.
abstract: The purpose of this retrospective study was to compare clinical parameters in preoperative, perioperative, and postoperative categories between valgus and varus deformities in primary total knee arthroplasty (TKA) following midvastus approach. We compared 83 patients (83 TKAs in valgus) with 949 patients (1084 TKAs in varus), with a mean follow-up of 72 months. In valgus deformity, mean age and body mass index at TKA were younger and smaller with more percentage of patellar subluxation. Cutting thickness from distal femur, tibial plateau, and lateral aspect of posterior femur were significantly different. The incidence of lateral release was 10.8% in valgus and 2.1% in varus. Although several significant differences were observed in preoperative and perioperative categories, the postoperative functional results were similarly evaluated by Knee Society knee and function scores.
