Hip Arthroscopy

Arthroscopy is a surgical procedure used to visualize, diagnose, and treat problems inside a joint. The procedure involves making a small incision in the skin and inserting a pencil-sized camera into an injured or damaged joint. The arthroscope’s tiny camera and instrumentation allow Dr. Samimi to see inside the joint in a magnified and illuminated manner to accurately diagnose and effectively treat the condition. Dr. Samimi specializes in the treatment of complex and routine hip problems that may be treated with arthroscopic techniques.

Arthroscopy is almost always performed as outpatient surgery and offers such benefits as reduced risk, fewer complications, less postoperative pain, less recovery time, and far less scarring. Using this minimally invasive procedure we can perform various hip procedures such as labral repair, cartilage restoration, loose body excision, and treatment of FAI (Femoral-Acetabular-Impingement).

Hip arthroscopy has been performed for many years, but is not as common as knee or shoulder arthroscopy.

During hip arthroscopy, your orthopedic surgeon can see the structures of your hip in great detail. Small instruments are used to repair torn cartilage.

Anatomy
The hip is a ball-and-socket joint. The socket is formed by the acetabulum, which is part of the large pelvis bone. The ball is the femoral head, which is the upper end of the femur (thighbone).

A slippery tissue called articular cartilage covers the surface of the ball and the socket. It creates a smooth, frictionless surface that helps the bones glide easily across each other.

The acetabulum is ringed by strong fibrocartilage called the labrum. The labrum forms a gasket around the socket.

The joint is surrounded by bands of tissue called ligaments. They form a capsule that holds the joint together. The undersurface of the capsule is lined by a thin membrane called the synovium. It produces synovial fluid that lubricates the hip joint.

In a healthy hip, the femoral head fits perfectly into the acetabulum.

When Hip Arthroscopy Is Recommended

Your orthopedic doctor may recommend hip arthroscopy if you have a painful condition that does not respond to nonsurgical treatment. Nonsurgical treatment includes rest, physical therapy, and 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 hip joint, inflammation causes swelling, pain, and stiffness.

Hip arthroscopy may relieve painful symptoms of many problems that damage the labrum, articular cartilage, or other soft tissues surrounding the joint. Although this damage can result from an injury, other orthopaedic conditions can lead to these problems, such as:

• Femoroacetabular impingement (FAI) is a disorder where bone spurs (bone overgrowth) around the socket or the femoral head cause damage.
• Dysplasia is a condition where the socket is abnormally shallow and makes the labrum more susceptible to tearing.
• Snapping hip syndromes cause a tendon to rub across the outside of the joint. This type of snapping or popping is often harmless and does not need treatment. In some cases, however, the tendon is damaged from the repeated rubbing.
• Synovitis causes the tissues that surround the joint to become inflamed.
• Loose bodies are fragments of bone or cartilage that become loose and move around within the joint.

Surgical Procedure
Before the operation, you will also be evaluated by a member of the anesthesia team. Hip arthroscopy is most commonly performed under general anesthesia, where you go to sleep for the operation. Regional anesthesia, such as spinal or epidural, can also be used. With regional anesthesia, you are awake but your body is numb from the waist down. Your orthopedic surgeon and your anesthesiologist will talk to you about which method is best for you. The length of the procedure will depend on what your surgeon finds and the amount of work to be done.

At the start of the procedure, your leg will be put in traction. This means that your hip will be pulled away from the socket enough for your surgeon to insert instruments, see the entire joint, and perform the treatments needed.

After traction is applied, your surgeon will make a small puncture in your hip (about the size of a buttonhole) for the arthroscope. Through the arthroscope, he can view the inside of your hip and identify damage.

Your surgeon will insert other instruments through separate incisions to treat the problem. A range of procedures can be done, depending on your needs. For example, your surgeon can:

• Smooth off torn cartilage or repair it
• Trim bone spurs caused by FAI
• Remove inflamed synovial tissue

Complications
Complications from hip arthroscopy are uncommon. Any surgery in the hip joint carries a small risk of injury to the surrounding nerves or vessels, or the joint itself. The traction needed for the procedure can stretch nerves and cause numbness, but this is usually temporary.

Sometimes, the damage in the hip can be severe enough that it cannot be completely reversed and the procedure may not be successful. There are also small risks of infection, as well as blood clots forming in the legs (deep vein thrombosis).

Recovery
After hip surgery, you will stay in the recovery room for 1 to 2 hours before being discharged home. You will need someone to drive you home and stay with you at least the first night. You can also expect to be on crutches, or a walker, for some period of time.

Rehabilitation
Your surgeon will develop a rehabilitation plan based on the surgical procedures you required. In some cases, crutches are necessary, but only until any limping has stopped. If you required a more extensive procedure, however, you may need crutches for 1 to 2 months.

In most cases, physical therapy is necessary to achieve the best recovery. Specific exercises to restore your strength and mobility are important. Your therapist can also guide you with additional do's and dont's during your rehabilitation after hip arthroscopy surgery.
