Metabolic processes are intricately linked to the resolution of innate inflammation and tissue repair, two critical steps for treating post-traumatic osteoarthritis (PTOA). Based on lipolytic and immunoregulatory actions of norepinephrine, we hypothesized that intra-articular β-adrenergic receptor (βAR) stimulation would suppress PTOA-associated inflammation in the infrapatellar fat pad (IFP) and synovium.
