Synovitis in orthopedics
Synovitis is an inflammation of the synovial membrane, which lines the joints and produces synovial fluid that lubricates them. In orthopedics, synovitis often presents as joint pain, swelling, and stiffness, commonly affecting weight-bearing joints like the knees, hips, and ankles. It can result from various conditions, including rheumatoid arthritis, osteoarthritis, and acute injuries.
