Results of Supracondylar "V" Osteotomy for the Correction of Genu Valgum Deformity.

Abstract

Medial close wedge, lateral open wedge, dome and "V" osteotomies are the commonly to correct the genu valgum (GV) deformity. However, the ideal method for the correction of coronal plane deformity is controversial. This prospective study is to evaluate the functional and radiological result of supracodylar "V" osteotomy to correct GV deformity. "V" osteotomy was done in all patients with clinically significant GV deformity and was fixed with crossed K-wires. Weight-bearing mobilization was started after radiological union. Patients were evaluated for correction in different clinical and radiological parameters. The function of the knee was assessed by Bostman's score. The subjective score was used to assess the parent's satisfaction after the procedure. 187 limbs with genu valgum deformity (47 males and 71 females) were included in this study. We observed a significant improvement in the mean intermalleolar distance, clinical and radiological tibiofemoral angle and lateral distal femoral angle, from 17.3 to 3.9 cm, 23.8°to-4.5°, 25.6° to 6.1°, 76.6° to 88.4°, respectively. The mean Bostman score improved from 20.6 to 28.1. The parent's satisfaction assessed subjectively was 95.3 points. This osteotomy along with the fixation with K-wires is a safe, effective, reproducible technique with a short learning curve and a procedure requiring no repeat surgery for implant removal, with good functional results, and without major complications.
