Osteoarthritis (OA), the most prevalent form of arthropathy, is characterized by progressive degradation of cartilage, synovial inflammation, and other pathological changes that gradually affect the entire joint. Once regarded as a purely degenerativ...
Background/Objectives: Osteonecrosis of the femoral head is a progressive disease that frequently leads to femoral head collapse and secondary osteoarthritis. Although total hip arthroplasty provides reliable outcomes, its use in younger patients is...
Background: High tibial osteotomy (HTO) was generally not indicated in patients with rheumatoid arthritis (RA) because synovial inflammation may exacerbate joint damage postoperatively. Recently, joint destruction in RA has dramatically changed with...
Traumatic joint injuries are common, leading to progressive tissue degeneration and the development of osteoarthritis. The post-traumatic joint experiences a pro-inflammatory milieu, initiating a subtle but deteriorative process in cartilage tissue....
