The functional outcome of medial compartment osteoarthritis of the knee treated with proximal fibular osteotomy: A Prospective Cohort Study

Abstract

Background: Osteoarthritis (OA) is a polyarticular chronic degenerative disease of multifactorial aetiology, and the most common joint to be afflicted is the knee. Objectives: To evaluate the clinical and functional outcomes of medial compartment OA of the knee treated
with PFO with respect to pain, disability, and range of movements. Materials and Methods: The present prospective cohort study consists of 60 patients with medial compartment knee OA treated by PFO of both genders who attended OPD and emergency in the orthopaedic department. The institutional ethical committee approved the study, and written informed consent was obtained from all the participants in the study.
Results: There were 36 (60%) females and 24 (40%) males with an M: F ratio of 1:1.5. The mean age of patients was found to be 58.72±8.29 years (P value = 0.26). Patients were followed up for range of motion at 3 months and 6 months. At the time of 3-month follow-up, 9 (15%) patients had a range of motion <80, whereas 21 (35%) patients had a range of motion between 80 and 90. 19 (31.67%) patients had ROM between 90 and 100. 11 (18.33%) patients were found to have ROM greater than 100. At the time of final follow-up at 6 months, 05 (8.33%) patients had a range of motion <80, whereas 21 (35%) patients had a range of motion between 80
and 90. 23 (38.33%) patients had ROM between 90 and 100. 11 (18.33%) patients were found to have ROM greater than 100.
Conclusion: PFO is a relatively easy, safe, fast, and effective procedure for the management of medial joint OA of the knee. It does not respond to conservative measures and results in improved functional and clinical outcomes, decreased knee joint pain, and an increased ML ratio.
