Proximal tibial valgusing open-wedge osteotomy union fixated with Anthony® "support" plate

OBJECTIVE: This paper aims to check the proximal tibial valgusing open-wedge osteotomy union with Anthony® plate for the treatment of bowleg with medial osteoarthrosis, final correction of the deformity and clinical improvement. METHODS: Twenty patients (twenty knees) with medial osteoarthrosis of the knee, with mean age of 48.4 years, were evaluated for one year. The patients were submitted to the Lysholm's score, and also to X-ray studies before and after surgery. RESULTS: The osteotomy union occurred after 12 weeks in all cases without complications. The Lysholm's score was regarded as excellent or good in 80% of the cases. The postoperative mechanical alignment was 3.4 ± 3.3 valgus. CONCLUSION: We conclude that the union happened within 3 months with the use of bone grafting and the Anthony® plate to fix the open wedge osteotomy. The open wedge osteotomy is effective in fixing the deformity of the knee providing a significant improvement to patients' lives.
