To Study the Functional Outcomes of Proximal Fibular Osteotomy in Osteoarthritis Kee

Abstract

Introduction: Knee osteoarthritis (OA), also known as degenerative joint disease, is typically the result of wear and tear and progressive loss of articular cartilage leading to radiologically decreased joint space. Proximal fibular osteotomy (PFO) is an alternative treatment to high tibial osteotomy (HTO). Hence; under the light of above mentioned data, the present study was undertaken for assessing the functional outcomes of proximal fibular osteotomy in osteoarthritis knee. Material and methods:A total of 10 patients with OA of knee were enrolled in the present study. The patients were placed in the supine position after administration of spinal anaesthesia. An approximately 5-cm longitudinal incision was made over the lateral aspect of the proximal fibula, and the fibula exposed between the peroneus muscle and soleus muscle. PFO was performed under the hands of skilled and experienced orthopaedic surgeon. Knee pain was assessed using a Visual analogue scale. Knee ambulation activities were recorded using the knee and function subscores of the American Knee Society score (KSS). All the results were recorded in Microsoft excel sheet and were analyzed by SPSS software. Chi-square test and Mann Whitney U test were used for assessment of level of significance. Results:Mean KSS score at pre-operative, postoperative, postoperative 6 weeks and postoperative 9 months were found to be 44.03, 53.50, 58.60 and 68.14 respectively. Significant results were obtained while comparing the mean KSS at different postoperative time intervals. In the present study, mean VAS score at pre-operative, postoperative, postoperative 6 weeks and postoperative 9 months were found to be 8.77, 6.96, 4.36 and 2.52 respectively. Significant results were obtained while comparing the mean VAS at different postoperative time intervals.Conclusion: PFO is a novel alternative method in the management of medial compartment arthritis of the knee.
