Knee synovitis is inflammation of the synovial membrane, the thin tissue lining the inside of your knee joint capsule. Normally, this membrane produces synovial fluid—a lubricating substance that helps your knee move smoothly and nourishes the cartilage. When the synovium becomes inflamed, it produces excess fluid and thickens, leading to swelling, pain, and restricted movement.
The condition can affect one or both knees and may develop suddenly or gradually. Acute synovitis often results from injury or infection. Chronic synovitis typically accompanies conditions like:
- Rheumatoid arthritis (an autoimmune disease where the body’s immune system attacks the joints)
- Osteoarthritis (wear-and-tear damage to joint cartilage)
The inflammation triggers a cycle where the swollen synovium produces more fluid, which further irritates the joint and perpetuates discomfort.
Knee synovitis treatment in Singapore focuses on reducing inflammation, managing pain, and addressing the root cause to help prevent recurrence. Left untreated, persistent synovitis can damage the cartilage and other joint structures, potentially leading to long-term joint problems. Early intervention may support better outcomes and preservation of knee function.
