1. What is Hip Joint Synovial Osteochondromatosis?
This condition is seen in young patients between the ages of 20-45 years. The inner lining of the hip joint starts to abnormally produce excess cartilage and bone like tissue. Normally this lining produces a lubricating fluid. These cartilage-like loose bodies within the hip joint initially irritate and then abrade the cartilage of the joint. Cartilage is the protective covering over the joint surface. Loss of this protective covering leads to arthritis and damage of the hip joint.
2. What are the symptoms?
Patients have pain in the hip, difficulty in walking, stairs, sitting cross-legged, squatting and other activities of daily living. In early cases patients are apparently normal but cannot walk long distances and complain of a particular heaviness of the hip joint.
3. What is the treatment?
Hip arthroscopy i.e surgery through small puncture wounds around the hip is needed. All the loose bodies and the joint lining is removed. This surgery avoids the traditional method where a big incision was taken, splitting the muscles and doing the surgery.
4. What is the hospital stay and the recovery period?
The stay in hospital is 2-3 days and patients can start walking with walker as soon as pain is tolerable. Usually patients are able to get back to office within 2-3 weeks.
5. Is there a chance of recurrence?
Yes, rarely this condition may recur but there it can be treated.
6. Why does this condition occur?
The cause of this condition is not known. Many researchers have tried to find a cause but could not.
7. What are loose bodies?
These are free pieces of bone or cartilage, which lie within the hip joint. They are like pebbles in a flowing river. They move within the joint with joint movement. A foreign body in the eye irritates the eye and the eye turns red and painful. Similarly a loose body in a joint irritates and over a long period of time causes destruction and arthritis of the joint.
8. How does a loose body come in the hip joint?
Usually a loose body enters the hip joint after a significant hip joint injury like road accident or fall from height, which causes a fracture of either bone of the hip joint. The other cause is synovial osteochondromatosis.
9. What are the symptoms and treatment for loose bodies?
The symptoms, treatment and recovery are similar to what has been given for synovial osteochondromatosis.
