CLINICAL AND FUNCTIONAL OUTCOME OF PROXIMAL FIBULAR OSTEOTOMY AND ARTHROSCOPIC DEBRIDEMENT FOR MEDIAL COMPARTMENT OSTEOARTHRITIS OF KNEE

Abstract

OBJECTIVE: To explore the effects of proximal fibular osteotomy and Arthroscopic debridement for pain relief and improvement of medial joint space and function in patients with knee osteoarthritis. METHODS: From January 2018 to December 2019, 22 patients who underwent proximal fibular osteotomy and arthroscopic debridement for medial compartment osteoarthritis were retrospectively followed up. To analyse the alignment of the lower extremity and ratio of the knee joint space (medial/lateral compartment preoperative and postoperative weight-bearing and whole lower extremity radiographs were obtained. Preoperatively and postoperatively at 6wks, 3 months, 6 months and 1 yr using a visual analogue scale,knee pain was assessed and knee ambulation activities were evaluated using the American Knee Society score RESULTS: Medial pain relief was observed in 20/22 patients after this procedure. Most patients exhibited improved walking postoperatively. An average increase in the postoperative medial knee joint space was seen in weight-bearing lower extremity radiographs. Additionally, obvious correction of alignment was observed in the whole lower extremity radiographs in 2 of 22 patients. But 25 % of patients had common peroneal nerve neuro-praxia which got improved over the period of average 6 months.
 CONCLUSIONS This study demonstrates that proximal fibular osteotomy and arthroscopic debridement in patients with medial compartment osteoarthritis effectively relieves pain and improves joint function at a mean of 15 months postoperative.
