Forty-seven patients (50 hips) with osteoarthrosis were treated with valgus osteotomy. The mean follow-up period was 4 years and 10 months. According to the JOA score, the preoperative scores (mean, 53.3 points) improved postoperatively (mean, 84 points). For the best result it is necessary that the incongruity be improved by a valgus osteotomy and the weight-bearing area be enlarged by a shelf operation.
