Background: Osteoarthritis (OA) commonly known as wear and tear arthritis. While it can occur even in
young people, the chance of developing osteoarthritis rises after age 45. Proximal bular osteotomy
(PFO) for young patients of OA knee joint is turning out to be an emerging concept with promising results. The aim of our study
was to evaluate clinical, radiological and functional outcomes of PFO in young patients of primary medial compartment
osteoarthritis of knee joint. Total 13 patients (20 knees) with moderate to severe pr Method: imary osteoarthritis of knee joint, who
underwent PFO, were enrolled. Clinical data, Visual Analogue Scale score (VAS), Knee Society Score (KSS), Medial Knee Joint
Space (MJS) and Femorotibial Angle measurements (FTA) were recorded. Patients were followed up at one, three, six months
and yearly, postoperatively. 20 knee joints PFO. The mean VAS scores signicantly decreased from Results: 8.25 preoperatively
to 2.21 at 12 months postoperatively. In most of patients, signicant medial pain relief was observed after PFO. Mean KSS at
preoperative stage was 44.15, which was improved to 77 at 12 months postoperatively, which further suggests improvement in
knee joint functions. There was noteworthy increase in Mean joint space postoperatively (1.17) as compared to preoperative
stage (0.34). Mean FTA reduced from 182.64 degrees preoperatively to 178.61 at nal follow up. Our study shows Conclusion:
that PFO remarkably causes pain relief and improves knee functions with increase in MJS and slight correction of varus
deformity in young patients with primary osteoarthritis of knee joint.
