Synovitis is the swelling or inflammation of the synovial membrane (joint-lining) and it is usually painful when the joint is moved.


Synovitis is disease (commonly found in rheumatoid arthritis) or any injury that causes white blood cells to move from blood stream into synovium. These synovium cells grow and divide abnormally and forms a synovial fluid and releases enzymes which may eventually destroy joint cartilage and bone.


The joint appears swollen and hard lumps called nodules and it is the better indication than tenderness. It may also include hip pain (on one side only), thigh pain (in front or towards the middle of thigh) and low-grade fever (less than 101°Fahrenheit). The release of enzymes from the cell into the joints may cause further pain and irritation. The joints get degenerated if the disease persists for a longer period.


The series of tests used to diagnose synovitis includes

  • Ultrasound of the joint
  • X-ray of the joint
  • Erythrocyte Sedimentation Rate (ESR)
  • C-Reactive protein(CRP)
  • Complete Blood Count (CBC)
  • Bone scan
  • Magnetic Resonance Imaging (MRI)


NSAIDS (Nonsteroidal Anti-inflammatory Medications) can be used to reduce the pain. There are specific treatments based upon the patient’s response and level of tolerance of any medications. But normal activities can be performed without any danger.


Synovitis heals much faster to conventional treatments. The duration depends upon the synovitis, if it is acute or chronic that causes inflammation or the number of joints involved. If the affected joint is rested properly it may improve within 7-10 days but it may take up to 8 weeks to recover completely. The chronic synovitis medication course will determine the outcome.


Synovitis commonly occurs to athletes who change their direction quickly or run on uneven surface, which are at higher risk for ankle injuries. The fluid in the synovial membrane will provide cushioning effect to large forces that acts on the ankles and the fluid also helps lubricating the joints which allow free movement. This can be reduced by adding a few stretches to your fitness program.

Treatment cost

Depending on treatment it ranges from $1000-$38000
