Tenolysis is surgery to release a tendon affected by adhesions. A tendon is a type of tissue that connects muscle to bone. An adhesion happens when scar tissue forms and binds tendons to surrounding tissue. This can make it difficult for the affected body part to work correctly. For example, adhesion in the fingers can cause the tendons to become stuck. This prevents the fingers from being able to move properly.
This surgery is often done on hands and wrists.
Reasons for Procedure TOP
You may have tendon adhesions if you had an injury to the area or if you had surgery that affected the tendon. Tenolysis is done when other therapies, like physical therapy, are unsuccessful.
In addition to tenolysis, other procedures may need to be done. The goal is to have full movement of the affected body part.
Possible Complications TOP
Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:

Description of the Procedure TOP
A tourniquet will be tied near the area where the surgery will occur. This will prevent blood flow to that area. An incision will be made in the skin to expose the tendon and surrounding tissue. The tissue will be cut to release the tendon. During surgery, your ability to move the affected body part will be checked. Based on the movement, the doctor can assess if the procedure is working or if additional procedures need to be done. This may include reconstructing the tendon. The incision will be closed with stitches.
How Long Will It Take? TOP
This depends on which tendon is affected and to what extent. For example, if you injured the flexor tendon in your finger, it can take 45-60 minutes to repair.
How Much Will It Hurt? TOP
Anesthesia will block pain during the procedure. You will have pain after the procedure. Ask your doctor about medication to help manage pain.
