Background: Knee osteoarthritis is a significant cause of functional restriction among the Indian population. In the initial stages when patients present with isolated medial compartment changes, the surgical options in the inventory are few. The scarcity of a simple yet cost-effective procedure has contributed to the growing popularity of isolated proximal fibular osteotomy (PFO) since its inception. This study aims to evaluate the outcome among patients who underwent PFO for symptomatic knee osteoarthritis. Materials and Methods: Fifty patients with medial unicompartmental osteoarthritis of the knee were treated with PFO from December 2017 to December 2020. Patient particulars and intra-operative parameters were recorded. The postintervention functional outcome was evaluated by comparing the preoperative Oxford Knee Score (OKS) with that reported postoperatively. Results: The mean age of the patients included in the study was 48.20 years, with a male: Female ratio of 1.8:1. Sixty-eight percent cases presented with Kellgren–Lawrence Stage III. The patients were followed for a mean of 18.18 months after the procedure. The preoperative, 1-month, 2-month, and 6-month OKS were 24.76 ± 2.63, 33.34 ± 3.84, 39.36 ± 4.65, and 43.02 ± 4.66, respectively. At 6 months postsurgery, 82% of patients were in the satisfactory functional score range (40–48). The most commonly observed complication was superficial peroneal nerve palsy. Conclusion: Despite the simple technique, PFO has been associated with good outcomes and lesser complications. Selection of patients and placement of the osteotomy site are crucial for the success of the procedure. The present study revealed that patients irrespective of their age, gender, or stage of the disease would benefit from the procedure.
