Preoperative Valgus Alignment Does Not Predict Inferior Outcome of Total Knee Arthroplasty.

ABSTRACT:

Background

Preoperative valgus deformity is present in an estimated 10-20% of patients undergoing total knee replacement (TKR).

Questions/purposes

The objective of this study was to compare the Western Ontario and McMaster Universities Arthritis Index (WOMAC) scores after TKR in a matched cohort of patients with preoperative valgus and varus deformities.

Methods

This is a matched cohort study of 162 patients with varus native knees and 162 patients with valgus native knees who underwent TKR and were prospectively followed in our institutional registry. Patients matched were based on age, BMI, sex, and severity of preoperative knee deformity, which was classified as mild, moderate, severe varus or valgus, or no deformity. Outcomes were evaluated using the WOMAC preoper
