To Study The Incidental Intraoperative Finding Of Unilateral Synovial Lipomatosis In A Patient Undergoing Total Knee Replacement

Abstract

INTRODUCTION: Synovial lipomatosis is an uncommon condition that affects the synovium, often occurring in the knee joint, particularly in the suprapatellar pouch. It leads to symptoms such as joint pain, swelling, and fluid buildup. This disorder requires further investigation because of its distinct features and clinical significance.
AIM AND OBJECTIVE: This study aims to examine the unexpected intraoperative finding of unilateral synovial lipomatosis in a patient being operated with total knee replacement, exploring its presentation and treatment.
MATERIAL AND METHODS: This study collected clinical data of a patient with complaints of bilateral knee pain and tri-compartmental osteoarthritic changes observed over both knee joints on pre-operative radiographs, planned for total knee replacement.
RESULT: Synovial lipoma is an uncommon intra-articular lesion usually located in the knee joint. MRI is the imaging technique of choice for diagnosis. A key differential diagnosis is lipoma arborescens, which has a different macroscopic appearance. Treatment typically consists of resection, often done arthroscopically..
CONCLUSION: We present an intraoperative case of synovial lipomatosis in a patient who underwent unilateral primary total knee replacement due to advanced osteoarthritis. This condition is part of the differential diagnosis for progressively swollen knees with chronic pain, often linked to synovial proliferative disorders, whether or not osteoarthritis is involved. Synovial lipomatosis is an uncommon cause of knee discomfort and swelling, with treatment options varying based on specific presentation.
