Stiff Knee (Arthrofibrosis) Surgical Treatment

What are the surgical treatment options for knee arthrofibrosis?

When range of motion of the knee continues to be significantly limited and affects overall function despite conservative treatment, surgical intervention is reasonable. The surgery recommended for a stiff knee is a knee arthroscopy, lysis of adhesions (LOA), and manipulation under anesthesia (MUA). During this procedure, Dr. Chahla will use a minimally invasive arthroscopic technique to remove the excessive scar tissue through 2-3 small incisions. Following the debridement of the excessive scar tissue, Dr. Chahla will then work the knee through extensive range of motion, further breaking up additional scar tissue. This is called a manipulation under anesthesia. In some cases when patients cannot achieve full extension (get their knees straight) a capsulotomy can be performed. This means releasing some of the attachments on the back of the knee that may be contractured to allow for better motion.

Following surgery, Dr. Chahla will prescribe a medication called Losartan to help prevent the formation of post-operative scar tissue. Dr. Chahla will also recommend aggressive physical therapy right from the start of your post-operative recovery in order to optimize your outcome.

What are the success rates of surgery for knee arthrofibrosis?

The success rates of surgery for knee arthrofibrosis can vary depending on several factors, such as the severity of the condition and the underlying cause. Generally, the success rates are quite high, especially when surgery is combined with post-operative physical therapy. It is critical that one attends aggressive physical therapy immediately following surgery for knee arthrofibrosis. Studies have shown that approximately 80-90% of patients experience improved range of motion and reduced pain after surgical intervention.
