| Background: Coronal plane knee deformities are common in daily orthopedic practice. It is more prevalent in adolescents. The treatment aim is to restore normal mechanical axis, permitting avoidance of stress on ligaments, articular surface and development of early arthritis. Aim and objectives: This study aimed to evaluate the correction degree and outcomes after surgical correction of genu valgum deformity in adolescents by distal femoral dome osteotomy. Subjects and methods: This prospective study involves 25 patients with genu valgum coming to outpatient clinic of the Damietta Faculty of Medicine, Al-Azhar University. All were submitted to preoperative evaluation (history, examination, radiological and lab investigation). Then underwent distal femoral dome osteotomy and followed up for at least 6 months, with outcome assessment on the clinical, radiological and functional basis. Results: All patients showed full correction except in one case, where undercorrection was recorded. There was a significant reduction of mechanical axis deviation (MAD) and intermalleolar distances (IMDs) postoperatively when compared to preoperative values (18.8±6.2, 14.8±2.5 vs 2.3±1.5 and 1.3±2.2, respectively). In addition, the postoperative measurements showed significant reduction of tibiofemoral angle (TFA), while mechanical lateral distal femoral angle (mLDFA) showed significant increase after intervention than preoperative values (89.2±1.2 vs 75.0±3.7). The post-operative complications were in the form of foot edema, limited extension of the knee, superficial wound infection and undercorrection in 12.0%, 8.0%, 4.0% and 4.0% respectively. No complications were reported among 18 subjects (72.0%). Conclusion: Distal femoral dome osteotomy is a viable and safe treatment option for genu valgum correction with early restoration of knee motion and function, early union with no leg length discrepancy. | ||
