Abstract
Objective To explore the early clinical effectiveness of proximal fibular osteotomy and surface replacement of the knee joint in the treatment of knee osteoarthritis accompanied by genu varus deformity for elderly patients. Methods From November 2014 to February 2015, a prospective self-controlled study was conducted in the Department of Orthopaedics of the First Affiliated Hospital of Bengbu Medical College to observe the early effectiveness of proximal fibular osteotomy of the knee joint on one side (in the group who received osteotomy) and surface replacement of the knee joint on the other side (in the group who received replacement) in the treatment for 10 elderly patients with osteoarthritis accompanied by genu varus deformity in the knees on both sides. Of the 10 patients, 2 were males, and 8 were females. Their ages ranged from 55 to 75 years. During preoperative and postoperative follow-ups, the patients' pain and function were evaluated by using the visual analog scale (VAS), the Hospital for Special Surgery (HSS) knee rating scale and the American Knee Society Score (KSS) scale. SPSS 21.0 software was used to perform a statistical analysis as well. Results All the patients experienced smooth surgery and postoperative follow-ups for 6-9 months. Before surgery, the differences of both the pain and function status in the osteotomy group and replacement group were not statistically significant (all P values>0.05). After surgery, both the pain and function status were improved markedly in the osteotomy group and replacement group. When the patients were conducted the final follow-up, their VAS scores, HSS scores as well as KSS clinical scores and function scores on both sides improved markedly than those before surgery, and the differences were statistically significant (all P values 0.05). Conclusions Proximal fibular osteotomy can remarkably alleviate the pain and improve the function in patients with knee osteoarthritis accompanied by genu varus deformity, and therefore, it is a safe and effective minimally invasive surgical technique.
