The Presence Of Sarcopenia In Patients With Knee Osteoarthritis

Multi-Dimensional Evaluation Of The Presence Of Sarcopenia In Patients With Knee Osteoarthritis

Osteoarthritis (OA) is one of the most common joint disorders worldwide . The knee is the most common symptomatic joint in osteoarthritis. In this study, we evaluated the presence of sarcopenia multidimensionally in patients with knee osteoarthritis (OA) using clinical, ultrasonographic and biochemical parameters, and in this respect, it was aimed to investigate the relation between OA and sarcopenia and to identify the most practical, easily accessible and inexpensive method for investigating sarcopenia.

102 patients with clinical and radiological diagnosis of knee osteoarthritis and 33 healthy control subjects were included in the study. A total of 135 subjects were evaluated using the European Working Group on Sarcopenia in Older People (EWGSOP) diagnostic criteria of sarcopenia. The first group consists of (OA) patients with sarcopenia, the second group consist of OA patients without sarcopenia and the third group is controls subjects. The detailed musculoskeletal system examination of the patients included in the study was carried out by a single physician, and complete blood count, renal function tests, electrolytes, total protein, albumin, 25 (OH) vitamin D, serum leptin, serum adiponectin, PTH, TSH and vitamin B12 values were recorded using the venous blood samples taken from the study group.Dual-X-ray absorptiometry (DEXA) is used to measure Body composition parameters and muscle mass measurements, isometric muscle strength evaluations, handgrip strength and gait speeds for diagnosis of sarcopenia. Short-form -36 (SF-36) The Nutritional Assessment-short form (MNA), the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), the International Physical Assessment Questionnaire Short Form (IPAQ-SF) and the Center for Epidemiologic Studies Depression Scale (CES-D scale) were administered to every patient as outcome measures.
