Evaluation of the short-term Clinical Outcomes of Proximal Fibular Osteotomy for Medial Compartment Knee Osteoarthritis A Case Series study

Abstract

Background & Aim: Osteoarthritis of knee is one of the important causes of knee pain in elderly patients and is a debilitating disease. It often leads to varus deformity of knee. Many treatment options are available for this progressive knee joint disorder. Proximal fibular osteotomy (PFO) is a novel yet simple procedure used to alleviate the symptoms of medial compartment knee osteoarthritis. In Low Income Countries (LIC), it could be an alternative surgical procedure for mild and moderate degrees of knee osteoarthritis

Materials and Methods: a Case Series study, We analyzed 30 patients who underwent PFO in Almouassat university hospital during the period from February to October 2019. Inclusion criteria are patient with grade 2 and 3 knee OA on radiographs. Visual Analogue Scale score (VAS score) and Oxford Knee Score were recorded. Patients were followed up 6 months postoperatively.

Results: 30 patients were enrolled in the study; 8 (26.7%) were men, and 22 (73.3%)
were women. The mean age of patients was 51.8 ± 4.1 years. The recorded mean preoperative Oxford knee score was 20.82 ± 1.97 and the mean postoperative was 35.92 ± 3.509. Mean recorded levels of VAS for pain postoperatively were 2.32 ± 0.792, which improved significantly from 7.90 ± 0.79.

Conclusions: The study highlights that the VAS and Oxford Knee scores were significantly improved after surgery. We can conclude that proximal fibular osteotomy may provide short-term relief in patients of medial compartment knee osteoarthritis. The PFO is a promising surgical option in countries that lack financial and medical resources.
