Arthroscopy is a minimally-invasive procedure used for the diagnosis and treatment of conditions affecting joints. The doctor can directly view the internal structures of a joint using an instrument called an arthroscope.
Orthopedic surgeons use arthroscopy to diagnose and treat joint problems. An arthroscope is a small, tube shaped instrument that is used to look inside a joint.
It consists of a system of lenses, a small video camera, and a light for viewing. The camera is connected to a monitoring system that allows the doctor to view a joint through a very small incision. The arthroscope is often used in conjunction with other tools that are inserted through another incision.
The joint most frequently examined using arthroscopy is the knee. However, arthroscopy can be used to examine other joints, including the following:
Joints are formed where bones meet. Most joints are mobile, allowing the bones to move. Basically, the knee is two long leg bones held together by muscles, ligaments, and tendons. Each bone end is covered with a layer of cartilage that absorbs shock and protects the knee.
There are two groups of muscles involved in the knee, including the quadriceps muscles (located on the front of the thighs), which straighten the legs, and the hamstring muscles (located on the back of the thighs), which bend the leg at the knee.
Tendons are tough cords of tissue that connect muscles to bones. Ligaments are elastic bands of tissue that connect bone to bone. Some ligaments of the knee provide stability and protection of the joints, while other ligaments limit forward and backward movement of the tibia (shin bone).
The knee consists of the following:
An arthroscopic procedure may be used to diagnose and assist in the treatment of the following conditions:
Corrective surgery or a biopsy may be performed using arthroscopy. For example, torn ligaments can be repaired or reconstructed. Arthroscopic surgery may eliminate the need for an open surgical procedure.
There may be other reasons for your doctor to recommend an arthroscopy.
As with any surgical procedure, complications can occur. Some possible complications may include, but are not limited to, the following:
There may be other risks depending on your specific medical condition. Be sure to discuss any concerns with your doctor prior to the procedure.
Arthroscopy may be performed on an outpatient basis or as part of your stay in a hospital. Procedures may vary depending on your condition and your doctor’s practices.
Arthroscopy may be performed while you are asleep under general anesthesia, or while you are awake under localized anesthesia. The type of anesthesia will depend upon the specific procedure being performed. Your anesthesiologist will discuss this with you in advance.
Generally, an arthroscopic procedure follows this process:
After surgery, you will be taken to the recovery room for observation. Your recovery process will vary depending on the type of anesthesia that is given. The circulation and sensation of the affected extremity will be monitored. Once your blood pressure, pulse, and breathing are stable and you are alert, you will be taken to your hospital room or discharged to your home. Arthroscopic surgery is usually done on an outpatient basis.
Once you are home, it is important to keep the incision site clean and dry. Your doctor will give you specific bathing instructions. If stitches are used, they will be removed during a follow-up office visit. If adhesive strips are used, they should be kept dry and generally will fall off within a few days.
Take a pain reliever for soreness as recommended by your doctor. Aspirin or certain other pain medications may increase the chance of bleeding. Be sure to take only recommended medications.
Activity and the use of the joint may be limited for 24 to 48 hours after a diagnostic arthroscopy. If other procedures are performed, such as a ligament repair, your activity and use of your joint may be limited for a longer period of time. Your doctor will give you specific instructions. For knee surgery, you may be given an immobilizer to wear. Your doctor may also instruct you to apply ice to the surgical site and to elevate the knee when sitting. Specific instructions will depend on the exact procedure performed.
Notify your doctor to report any of the following:
You may resume your normal diet unless your doctor advises you differently.
Your doctor may give you additional or alternate instructions after the procedure, depending on your particular situation.
