J Exp Orthop. 2016 Dec;3(1):18. doi: 10.1186/s40634-016-0054-4. Epub 2016 Aug 19.

BACKGROUND: Interleukin-1 receptor antagonist (IL-1 ra) can be disease-modifying in posttraumatic osteoarthritis (PTOA). One limitation is its short joint residence time. We hypothesized that IL-1 ra encapsulation in poly (lactide-co-glycolide) (PLGA) microspheres reduces IL-1 ra systemic absorption and provides...
