Summary
Injectable hydrogels offer a promising new approach to osteoarthritis (OA) treatment by targeting its complex mechanisms. These advanced therapies provide superior advantages over traditional methods for managing OA progression.
Area of Science:
- Biomaterials Science
- Regenerative Medicine
- Orthopedics
Background:
- Osteoarthritis (OA) is a degenerative joint disease driven by complex interactions within the cartilage, bone, and synovium.
- Current OA treatments are palliative and do not fully address the disease's underlying pathophysiology.
- Microenvironmental dysregulation is a key factor in OA progression.
Purpose of the Study:
- To review recent advancements in injectable hydrogel-based therapies for osteoarthritis.
