Arthroscopic joint debridement
What is arthroscopic joint debridement?
This is minimally invasive surgery to the lining of the ankle joint (the area predominantly effected by arthritis).
Go to the "Ankle Arthroscopy Section" for a full description of the operative technique, reasons for minimally invasive surgery to the ankle and the post-operative course.
In principle how does it work?
It works by removing areas of loose, mechanically redundant cartilage (joint lining) and inflamed tissue (synovitis) from the joint.
Occasionally there may be "spurs" of bone (osteophytes) at the front of the joint which "dig" at the front of the ankle when walking. These can also be removed as can loose fragments of bone within the joint, which can cause the joint to jar or "give way".
What does the inside of a "salvageable" joint look like?
When/in whom is arthroscopic joint debridement likely to be of use?
This is a procedure really likely to be of use only in mild to moderate arthritic cases. It is not a precise science advising when one is in this category. The typical patient has symptoms which are not too severe, probably limited to pain when putting weight through the joint, and there is some reasonable joint space left on weight bearing x-rays.

How likely is this procedure to improve my pain?
Approximately 75% chance of improving pain. It is important to be clear that the operation is unlikely to leave the patient free of all pain, but is likely to improve things significantly.
It is also important to realise that there is a risk, of the order of 15%, that arthritic symptoms can be worsened to the extent that a fusion is required.
