Arthroscopic synovectomy in haemophilia: indications, technique and results.

Recurrent spontaneous haemarthrosis are commonly seen in patients affected by haemophilia. The knee and the elbow are most commonly affected and both are amenable to arthroscopic treatment. Arthroscopic synovectomy is indicated after failure of appropriate medical management with recurrent bleeding. Many patients also demonstrate motion loss and functional deterioration. The benefits of arthroscopic synovectomy include the ability to perform adequate synovial debridement, but also concomitant lysis of adhesion and capsular release to regain range of motion. Results of arthroscopic synovectomy demonstrate a significant decrease in episodes of haemarthrosis, and significant improvement in pain, range of motion and function. The primary predictor of outcome is degree of pre-existing degenerative changes within the joint. In more severe cases, the results of arthroscopic synovectomy are unpredictable and serious consideration should be given to primary arthroplasty.
