The longitudinal relationship between changes in body weight and changes in medial tibial cartilage, and pain among community-based adults with and without meniscal tears

Abstract

Introduction: Meniscal tears are commonly found on MRI and increase the risk for radiographic knee osteoarthritis (OA). While meniscectomy is recommended when knee pain is severe or functionally disabling, it is unclear how to best treat meniscal tears without these symptoms. The aim of this longitudinal study was to examine the effect of weight change on knee cartilage and pain in a cohort of community-based adults with and without meniscal tears detected by MRI. Methods: 250 adults with no history of knee OA or knee injury were recruited from the general community and weight-loss clinics. MRI of the knee, Western Ontario and McMaster University Osteoarthritis Index (WOMAC), weight and heig..
