Elbow Arthroscopy

Arthroscopy is a procedure that orthopaedic surgeons use to visualize and treat problems inside a joint.

The word arthroscopy comes from two Greek words, "arthro" (joint) and "skopein" (to look). The term literally means "to look within the joint." During elbow arthroscopy, your surgeon inserts a small camera, called an arthroscope, into your elbow joint. The camera displays pictures on a monitor, and your surgeon uses these images to guide miniature surgical instruments.

Because the arthroscope and surgical instruments are thin, your surgeon can use very small incisions (cuts), rather than the larger incision needed for open surgery. This results in less pain for patients, less joint stiffness, and often shortens the time it takes to recover and return to favorite activities.

Elbow arthroscopy has been performed since the 1980s. There are many nerves around the elbow which make elbow arthroscopy challenging. However, in conditions that are safe to treat with arthroscopic surgery, the procedure has made diagnosis, treatment, and recovery from surgery easier and faster than was once thought possible. Improvements to elbow arthroscopy occur every year as new instruments and techniques are developed.

Anatomy

The elbow is a complex joint formed by the joining of three bones:

  • The humerus (upper arm bone)
  • The ulna (forearm bone on the pinky finger side)
  • The radius (forearm bone on the thumb side)

The surfaces of the bones where they meet to form the elbow joint are covered with articular cartilage, a smooth substance that protects the bones and acts as a natural cushion to absorb forces across the joint. A thin, smooth tissue called synovial membrane covers all remaining surfaces inside the elbow joint. In a healthy elbow, this membrane makes a small amount of fluid that lubricates the cartilage and eliminates almost any friction as you bend and rotate your arm.

On the inner and outer sides of the elbow, ligaments (collateral ligaments) hold the elbow joint together and prevent dislocation.

The elbow joint is surrounded by muscles on the front and back sides. In addition, the three major nerves that cross the elbow joint are located close to the joint surfaces and capsule and must be protected during arthroscopic surgery.

Bones of the elbow joint include the humerus (upper arm bone) and the ulna and radius of the forearm. Ligaments hold the elbow joint together and prevent dislocation.

The elbow joint allows two basic movements:

  • Bending and straightening (flexion and extension). Normal bending and straightening motions occur at the joint between the humerus and ulna bones.
  • Forearm rotation (pronation — palm down, and supination — palm up). Forearm rotation occurs at the joint between the ulna and radius. It is also influenced by muscles and ligaments further down the forearm and at the wrist joint.

When Is Elbow Arthroscopy Recommended?

Your doctor may recommend elbow arthroscopy if you have a painful condition that does not respond to nonsurgical treatment. Nonsurgical treatment includes:

  • Rest.
  • Physical therapy.
  • Medications or injections that can reduce inflammation. Inflammation is one of your body's normal reactions to injury or disease. In an injured or diseased elbow joint, inflammation causes swelling, pain, and stiffness.

Most elbow problems are due to either:

  • Injury
  • Overuse
  • Inflammatory conditions, like rheumatoid arthritis
  • Age-related wear and tear

Elbow arthroscopy may relieve painful symptoms of many problems that damage the cartilage surfaces and other soft tissues surrounding the joint. Elbow arthroscopy may be recommended to:

x-ray of elbow osteoarthritis

This X-ray of an elbow taken from the side shows severe osteoarthritis. Note the large bone spurs that have formed around the joint. During an arthroscopic procedure, these bone spurs can be removed, along with any loose fragments of cartilage.

There are several elbow surgical treatments that are currently still most effective when done as an open, traditional procedure. These include surgeries to:

Some advanced surgeries combine arthroscopic and open procedures in the same setting. For example, in a severe case of osteochondritis dissecans, a loose piece of bone may be removed arthroscopically, and the damaged area of the humerus may be treated with a bone graft using an open surgical technique.

Planning For Surgery

Evaluations and Tests

Your orthopaedic surgeon may ask you to see your primary doctor to make sure that you do not have any medical problems that need to be addressed before your surgery. Blood tests, an electrocardiogram, or chest X-ray may be needed to safely perform your surgery.

If you have certain health risks, a more extensive evaluation may be necessary before your surgery. Be sure to inform your orthopaedic surgeon of any medications or supplements that you take. You may need to stop taking some of these prior to surgery.

If you are generally healthy, your arthroscopy will most likely be performed as an outpatient procedure, meaning you will not need to stay overnight at the hospital. However, there are some procedures that have better results when patients stay in the hospital afterward for close monitoring, physical or occupational therapy, and/or pain control. Your surgeon will discuss a hospital stay with you if necessary.

Anesthesia

Elbow arthroscopy may be performed with:

  • General anesthesia, meaning you are put to sleep with a breathing tube
  • A regional nerve block that numbs your arm
  • A combination of both types of anesthesia

Sometimes, the regional nerve block is placed after your procedure, while you are in the recovery room, so your surgeon can make sure your nerves are functioning well after surgery and that there has not been any injury.

Surgical Procedure

Positioning

Once in the operating room, you will most likely be given general anesthesia (see Anesthesia section above), as well as intravenous antibiotics. Antibiotics are typically given before surgery to lessen the risk of infection after surgery.

You will then be positioned so that your surgeon can easily adjust the arthroscope to have a clear view of the inside of your elbow. The two most common positions for elbow arthroscopy are:

  • Lateral decubitus (lying on your side)
  • Prone (lying on your stomach)

Some surgeons may also choose to perform this procedure supine (with you lying on your back). The decision is often based on surgeon preference.

Care is taken to ensure that your spine and other pressure points in your arms and legs are protected and padded after positioning.

Next, a tourniquet is applied to your upper arm which is then placed in an arm holder to keep it in position during the procedure. A compressive dressing may be applied to your lower arm and hand to limit swelling. The surgical team will clean your skin with antiseptic and cover your shoulder and upper body with sterile surgical drapes.

Surgeons typically draw lines on the elbow to indicate specific structures (such as the ulnar nerve and olecranon bone), as well as incision placements and portals for the arthroscope. This is done to minimize the risk of injury to the vital structures, like nerves, around the elbow.

Procedure

  • Your surgeon will first fill the elbow joint with fluid. The fluid helps your surgeon more clearly see the structures of your elbow through the camera on the arthroscope. This lessens the risk of injury to the blood vessels and nerves surrounding your elbow joint.
  • Your surgeon will make several small incisions to introduce the arthroscope and small instruments into the joint. Fluid flows through the arthroscope to keep the view clear and control any bleeding. Images from the arthroscope are projected on the video screen showing your surgeon the inside of your elbow and any problems.
  • Your surgeon will evaluate the joint before beginning any specific treatments. If necessary, the entire joint will be evaluated, which may require a total of 5 or 7 more very small arthroscopy incisions (cuts). 
  • Specialized instruments, inserted through the small cuts, are used for tasks like shaving, cutting, grasping, suture passing, and knot tying. In many cases, special devices are used to anchor stitches into bone.

  • The arthroscopy incisions are usually stitched or covered with skin tapes at the end of the surgery. An absorbent dressing is applied to the elbow. Depending on the procedure, your surgeon will place either an additional soft dressing that will allow movement or a plaster splint that will restrict movement and better protect the elbow.

Recovery

Postoperative

After surgery, you may stay in the recovery room for several hours before being discharged home (if you are having outpatient, or same-day, surgery). For some complex arthroscopic procedures, patients may be admitted to the hospital overnight.

Nurses will monitor your responsiveness and provide pain medication, if needed.

You will be provided discharge instructions that cover medications, need for ice and elevation, as well dressing care.

You will need someone to drive you home and stay with you for at least the first night.

At Home

Although recovery from arthroscopy is often faster than recovery from open surgery, it may still take weeks to months for your elbow joint to completely recover.

Medications

You can expect some pain and discomfort for several weeks after surgery. If you have had a more extensive surgery, however, it may take longer before your pain subsides.

Your doctor will likely prescribe pain medicine to be taken regularly for the first few days after surgery. In addition, other medicines such as stool softeners or anti-inflammatory medicines may be prescribed.

Icing and Elevation

It is important to ice and elevate your elbow regularly for 48 hours after surgery. This will reduce the risk of severe swelling and help to relieve pain. Icing can sometimes be difficult if you have a bulky dressing.

When elevating your arm, whether you lie flat or recline, make sure your elbow is resting higher than your heart and your hand is positioned higher than your elbow. Depending on the type of surgery performed, your doctor may have specific instructions for longer periods of ice and elevation.

Movement and Exercises

You will most likely be encouraged to move your fingers and wrist frequently to help stimulate circulation and minimize swelling.

Your doctor may recommend early range-of-motion exercises to prevent joint stiffness. When you can start these gentle exercises, as well as return to daily activities, will depend on the type of surgery performed.

Dressing Care

Dressing care will also depend on the type of surgery performed and the preferences of your doctor.

In most cases, the operative dressing and/or splint is removed 2 to 3 days after surgery. While you are wearing the dressing, it must be left intact and kept dry. In some instances, you may be instructed to keep the dressing in place until your first postoperative clinic visit with your doctor.

Rehabilitation

Rehabilitation plays an important role in getting you back to your daily activities. An exercise program will help you regain elbow and forearm motion and strength. Your surgeon will develop a rehabilitation plan based on the surgical procedures you required.

  • In some cases, your doctor will provide you with basic exercises to begin at home — with the help of a family member, friend, or caregiver — a few days following surgery.
  • In more advanced surgeries, physical therapy is often prescribed after the first postoperative visit to enable motion and restore strength and function to the elbow. The type and duration of therapy will depend on the type of problem you have and the type of surgery that was performed.

Return to driving, basic activities of daily living, and return to work will also depend on the type of surgery you had and should be discussed with your doctor.

Complications

Most patients do not experience significant complications from elbow arthroscopy. As with any surgery, however, there are some risks. These are usually minor and treatable and not likely to affect your final outcome.

Potential problems with elbow arthroscopy include:

  • Infection
  • Excessive bleeding
  • Blood clots
  • Damage to blood vessels or nerves; when they occur, nerve injuries are significant and are due to the proximity (closeness) of nerves to the elbow joint capsule

Most studies do report a slightly higher risk of infection and nerve irritation/injury following elbow arthroscopy as compared to arthroscopy of the shoulder and knee joints.

Your doctor will discuss the potential risks and benefits of elbow arthroscopy with you prior to surgery. These risks depend somewhat on the specific type of surgery you will be having.

Long-Term Outcomes

Because patients have varied elbow conditions, complete recovery time is different for everyone.

  • If you have had a minor repair, you may not need a splint and your range of motion and function may return after a short period of rehabilitation. You may be able to return to work or school within a few days of your procedure.
  • If you had a more complicated procedure, recovery may take longer. Although the incisions are small in arthroscopy, extensive damage within the joint may have required extensive work. Full recovery may take several months. Although it can be a slow process, following your surgeon's guidelines and rehabilitation plan is vital to a successful outcome.
