Randomized controlled study of proximal fibular osteotomy (PFO) with or without trabeculotomy in early osteoarthritis (OA) knee

Abstract

This study was conducted to evaluate and compare the clinical and functional outcome of OA knee patients treated with proximal fibular osteotomy with or without trabeculotomy.This was a randomized controlled study amongst patients of osteoarthritis knee for a period of 1 year on patients with early osteoarthritis of knee. All patients were randomly allocated into two groups; group 1 patients were managed using PFO with trabeculotomy whereas group 2 patients were managed with proximal fibular osteotomy alone. All the patients were followed up post operatively at 15 days and at 2, 6 and 12 months post operatively. At each follow up patients were assessed for presence of Pain using Visual analogue scale. Also functional outcome was assessed using WOMAC.In present study, patients of two groups were comparable in their base line characters (p>0.05). Post operatively, mean VAS score and WOMAC score improved significantly in both the groups, the improvement was significantly higher in group 1 as compared to group 2 at all the follow up (p<0.05).Proximal fibular osteotomy with or without trabeculotomy can be used effectively as a promising tool for management of cases with early osteoarthritis of knee. It is safe, effective, and cost effective surgical technique for pain relief and improving functional outcome. PFO with trabeculotomy yields better results in terms of clinical as well as functional outcome as compared to PFO without trabeculotomy.
