Abstract :
Introduction: Knee osteoarthritis (OA) is a chronic, progressive degenerative disease with joint pain, stiffness, and deformity. Knee OA is a common joint disease, with an incidence of 30% of the population older than 60 years. High tibial osteotomy and total knee arthroplasty are the 2 commonly used methods for treating knee OA. Total knee Arthroplasty (TKA), which aims to relieve pain and improve joint function and mobility, primal fibular osteotomy (PFO) is the main surgical alternative in this patient population.
Materials and Methods: From September 2017 to September 2019, the PFO was performed for patients presenting with medial compartment osteoarthritis. Preoperative and postoperative weight-bearing whole lower extremity radiographs were obtained to analyze the alignment of the lower extremity and the ratio of the knee joint spaces (medial/lateral compartment) were ascertained. Knee pain was assessed using a visual analog scale (VAS), and knee ambulation activities were evaluated using the Knee Society Score (KSS).
Results: A total of 20 patients and 26 knees were followed-up for a minimum period of one year. Of these, 7 were male and 13 were female patient. The average age was 57 years. According to Kellgren Lawrence grading, there were 18 knees of grade 2 and 2 knees of grade 3. The average preoperational VAS score and KSS were 6.3 and 33.5 respectively. The average postoperative VAS score and KSS improved significantly to 2.8 (P
Conclusion: PFO is a promising alternative procedure in the management of medial compartment osteoarthritis of the knee being a simple and cost-effective alternative to the traditional total knee or unicondylar knee replacements. A longer period of follow-up is necessary to evaluate whether the beneficial effects of PFO are sustained over a period of time.
