Objective: Main aim of this study was to observe the outcomes of proximal fibular osteotomy in unicompartmental (Medial) osteoarthiritis  of knee joint.

Patients & Method: A prospective clinical study was undertaken from May 2019 to October 2020 on total 32 patients. Preoperative and postoperative weight bearing and whole lower extremity Radiographs were obtained to analyze the alignment of the lower extremity and ratio of the knee joint space (Medial / lateral Compartment).

Both preoperative and postoperative knee pain was assessed by using a VAS (Visual Analogue scale) and knee Ambulation activities by American knee society score.

Results: After PFO

1. Pain- Relief of Medial Compartment pain was observed in almost all patients.
2. Knee ambulation- In most of the patient’s knee ambulation improved post-operetively.

• Medial / Lateral compartment  space ratio improved

1. Lower extremity radiographs- correction of alignment observed in 9 patients out of 30 patients.

Conclusion: This prospective study demonstrates that PFO effectively reliefs pain and improves  joint functions in  patients with  medial compartment osteoarthirits of knee at a mean of 10.4 months post operatively.
