Preoperative and postoperative knee society score (KSS) and visual simple scale (VAS) were acquired to survey knee capacities and torment Results: Median knee society score (KSS) show improvement postoperatively from46 to 82 and visual simple scale (VAS) diminished postoperatively from 7 to 1.4. Ends: This investigation shows that proximal fibular osteotomy (PFO), another medical procedure, can adequately diminishes torment and improves knee work in patients with average compartment osteoarthritis.
