Synovium is the joint lining membrane of the body. Any injury or inflammation caused in this part is known as synovitis. Synovitis is usually indicated by severe pain, redness and swelling. At times, synovitis can spread to the other joint also. Boys, mainly preschool to early school-aged kids, are more affected than girls.


The main cause of synovitis is seen to be arthritis especially rheumatoid arthritis. It is also associated in people suffering from tuberculosis, rheumatic fever, gout or trauma.


Hip pain is the most common symptom noticed in people. Other symptoms include:

  • Limp
  • Low-grade fever
  • Severe pain in front and middle portion of thigh
  • Pain in knee
  • Difficulty in walking


Prior to treatment, the proper diagnosis of disease is essential. Synovial fluid analysis is the main test done in diagnosis. It detects the presence of arthritis in the affected patient. In moderate cases, non-surgical methods are used. In case of persisting symptoms, surgery is required.

  • Non-surgical Treatments:

The commonly used non-surgical methods are:

  • Medications

Medications are widely used to give temporary relief from inflammation. Ibuprofen and naproxen are the commonly used counter medications.

  • Rest

The affected part should be kept in rest for its faster healing. Walking exercise is usually recommended, however, aggressive exercises should be avoided. Avoid putting heavy weight on the injured part.

  • Surgical Treatments:

When the symptoms persist for a long-term period, surgery is chosen as the treatment procedure. The different types of surgery used are:

  • Arthroscopy

In arthroscopic surgery, a tiny cut is made at the site to be operated. A camera along with specialized surgical instruments is inserted through the incision. The camera is used to get the inside view of the affected part in the television screen. This helps to properly guide the instruments to the appropriate place. These instruments are used to partially remove the affected joint lining along with complete mass. The advantage of this surgery is that recurrence rate of this problem is lowered.

  • Open surgery

In people with diffused synovitis, open surgery is recommended. In such cases, both front and back of the knee is affected. During surgery, the entire joint lining along with mass is surgically removed. The recovery time in open surgery is normally longer than arthroscopic surgery.


In post-operative period, specific exercise therapy is prescribed to patient. This therapy is useful in regaining the functionality of the body. For arthroscopic surgery, a short-term recovery process is sufficient. In open surgery, a controlled and extensive therapy is required. It may sometimes take a few months for the entire recover process.


The commonly noticed risks include:

  • Severe inflammation and pain at the operated area
  • Bleeding
  • Blood-clots
  • Limited range of motion
  • Infection
