The association between obesity and osteoarthritis (OA) is nowadays well-accepted. This association is present both in weight-bearing and non-weight-bearing joints, indicating that next to local effects, systemic effects associated with obesity could play a role in disease. The relative contribution of local and systemic effects could be different in each joint. In this presentation, I will summarize the current knowledge about the contribution of local and systemic adipose tissues to osteoarthritis in different joints, with emphasis on knee OA. Moreover, obesity-associated changes and their role in OA will be highlighted.
The key messages I would like to convey are:
Mechanical stress is a major contributor to knee OA
The infrapatellar fat pad (IFP), an intra-articular adipose tissue in the knee, is dostinct from other adipose tissues and could play a role in knee OA
Only few obesity-related features have been described in IFP in OA
