Abstract: Objective: To evaluate the functional and radiological outcome in medial compartment osteoarthritic knee treated with proximal fibular osteotomy as a new modality of treatment.
Materials and Methods: Fifteen patients (10 men and 5 women, age range between 50-68 years) from May 2016 to May 2018 who had undergone proximal fibular osteotomy for medial compartment osteoarthritis knee were followed prospectively. Pre-operative and post-operative weight bearing scan gram obtained to analyse the alignment of lower limb (Femoro tibial angle) and ratio of joint space (medial/lateral joint space). Functional Outcome was assessed with American Knee Society Score (KSS) and Knee pain was assessed with Visual analogue scale.
Results: At final followup the mean Femoro-Tibial angle and joint space ratio were 180.4 and 0.54 respectively. The limb alignment is corrected in few cases and joint space ratio is increased postoperatively. Mean Knee Society Score at final follow up was 75.13 which was higher than the mean preoperative score 52.5.Mean Vas score is reduced significantly up to 4(preoperative mean Vas score was 8).
Conclusion: The present study demonstrates the proximal fibular osteotomy effectively relieves the pain and improves the joint function in the patients with medial compartment osteoarthritis of knee by shifting the mechanical axis. Conversion to total knee replacement or unicompartmental arthroplasty is also less complicated.
