Arthroscopy is a surgery done to examine a joint visually. Most of the time, it is done on larger joints, like the knee or shoulder. A special tool called an arthroscope is used. It is an instrument that looks like a long tube with a miniature camera on the end. Repairs or corrections to the joint may be done by using the arthroscope and other tools.

It is used to see, diagnose, and treat problems inside your joint. The procedure is most often performed for the following reasons:
- Diagnose an injury or disease inside a joint
- Remove bone or cartilage
- Repair tendons or ligaments
Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:
- Blood clots
- Swelling or bleeding
- Damage to blood vessels, nerves, or other tissue
- The need to have another surgery or more extensive surgery
Factors that may increase the risk of complications include:
Your doctor will likely do the following to evaluate the joint:
- Arrange for a ride to and from the procedure.
- The night before, do not eat or drink anything after midnight.
- You may be asked to use a special soap the morning of the procedure.
The type of anesthesia will depend on the joint your doctor is looking at. You may receive one of the following:
The doctor will make tiny incisions in the skin along the joint. Special tools will be inserted through the incisions. The tools include the arthroscope. The picture from the arthroscope will show up on a screen so that the doctor can see the inside of your joint. The doctor may use the images to move around other tools that can cut and repair tissue in your joint.
in the knee will be repaired by cutting out some of the cartilage.
- Carpal tunnel syndrome
in the wrist may be treated by loosening the ligament that puts pressure on the nerves.
Once the examination or surgery is done, the tools will be removed. The skin may be closed with stitches or clips. The incisions will be covered with a dressing. The fluid or tissue that was removed may be sent to a lab for examination.
Usually less than one hour, but this may be longer if repairs are being done.
Anesthesia will prevent pain during surgery. Pain and discomfort after the procedure can be managed with medications.
The dressings can sometimes be removed as early as the next morning. When you return home after the procedure, do the following to help ensure a smooth recovery:
It takes 4-6 weeks for the joint to recover. You can probably go back to work or resume daily activities within a few days, as long your doctor approves.
You may be instructed to
or a cane for the first few days if the surgery was done on a joint in your legs.
A specific activity and rehabilitation program may be suggested. This will help speed your recovery and protect future joint function.
Athletes often return to athletic competition within a few weeks.
Repair of the anterior cruciate ligament (ACL) by arthroscope may require a recovery time of 4-6 months and a more specialized rehabilitation program.
It is important to monitor your recovery. Alert your doctor to any problems. If any of the following occur, call your doctor:
- Signs of infection, including fever and chills
- Redness, swelling, increasing pain, excessive bleeding, or any discharge from the incision site
- Persistent nausea and/or vomiting
- Pain that you cannot control with the medications you've been given
- Cough, shortness of breath, or chest pain
- Joint pain, fatigue, stiffness, rash, or other new symptoms
- Swelling, tingling, pain, or numbness in your toes that is not relieved by elevating your knee above heart level for one hour
If you think you have an emergency, call for medical help right away.
