To evaluate the functional outcomes of proximal fibular osteotomy in osteoarthritis knee: A study of 30 cases

Abstract

Background: Osteoarthritis (OA) is the most common form of arthritis in the world. Proximal fibular osteotomy (PFO) is an alternative treatment to high tibial osteotomy (HTO). It is a surgical procedure for medial compartment knee osteoarthritis (KOA). Hence; the present study was undertaken for assessing the functional outcomes of proximal fibular osteotomy in osteoarthritis knee. Materials & Methods: A total of 30 patients were assessed. 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. Knee pain was assessed using a Visual analogue scale. Medical joint space and the hip knee-ankle angle was measured. based on the whole lower extremity radiograph Results: Significant improvement was observed in the mean VAS improved from preoperative value of 8.23 to 2.1 at 9 months postoperative follow-up. Significant improvement was observed in the Mean knee joint space from preoperative value of 0.35 to 0.58 at 9 months postoperative follow-up. Significant improvement was observed in the mean hip knee ankle angle from preoperative value of 184.2 to 177.3 at 9 months postoperative follow-up.Conclusion: PFO is a novel alternative method in the management of medial compartment arthritis of the knee.
