Biomechanical Loading As A Driver Of Synovial Neovascularization And Microvascular Dysfunction In Knee Osteoarthritis, Mckenzie Carter Mar 2022

Biomechanical Loading As A Driver Of Synovial Neovascularization And Microvascular Dysfunction In Knee Osteoarthritis, Mckenzie Carter

Electronic Thesis and Dissertation Repository

Synovial inflammation and biomechanical loading are independent risk factors for knee osteoarthritis (OA). However, the relationship between inflammatory and biomechanical factors, specifically if increased biomechanical loading causes synovial inflammation in OA (mechanoinflammation), is not well understood. The purpose of this thesis was to explore the associations of knee load during walking with features of synovial inflammation in knee OA. The knee adduction moment magnitude was associated with increased synovial vascularization and perivascular edema. Synovial fluid from OA patients with high knee adduction moments promoted endothelial cell migration in vitro. Late-stage knee OA synovial fluid caused endothelial monolayer hyperpermeability in …
