ABSTRACT

Objective: To know the number of good and bad results with correction of angular deformities of the knee with hemiepiphysiodesis. To know if hemiepiphysiodesis is adequate for correcting angular deformities. Material and methods: Fourteen patients with 18 deformities were reviewed in Shriners Hospital for Children Mexico City, treated with proximal tibial hemiepiphysiodesis, between January of 1995 and December 2003, with a minimal follow-up of 24 months. We measured the femoro-tibial angle before surgery and at the follow-up visit. Results were classified as excellent when normality was achieved, good when they were within 5° of normality and poor when they were within more than 5°. Normal range was considered to be between 6 and 12°. Results: 56% of patients (10) were male and 44% (8) female, 67% (12) had valgus of the knee, 33% (6) had varus, there were no changes in the range of movement of the knee before and after surgery. There were no infections. All surgeries were done percutaneously with a drill bit. Average correction was 11° (2-20°). Average age was 11.5 years (10-13 years). Results were excellent in 11 patients (61%), good in 4 (22%) and poor in 3 (17%). Discussion: Hemiepiphysiodesis has lower morbidity than an osteotomy and has a shorter rehabilitation period, since it requires no immobilization. There are less complications. The moment of surgery must be properly determined. Conclusions: Excellent results were obtained in 61% of patients. Hemiepiphysiodesis is an alternative for treatment of angular deformities of the knee.
