Arthroscopy is a surgical procedure during which the internal structure of a joint is examined for diagnosis and treatment of problems inside the joint. In arthroscopic examination, a small incision is made in the patient’s skin through which pencil-sized instruments that have a small lens and lighting system (arthroscope) are passed. Arthroscope magnifies and illuminates the structures of the joint with the light that is transmitted through fiber optics. It is attached to a television camera and the interior of the joint is seen on the television monitor.
Arthroscopic examination of joints is helpful in diagnosis and treatment of the following conditions:
Inflammation: Synovitis, the inflammation of the lining of the knee, shoulder, elbow, wrist, or ankle
Acute or chronic injury: Injuries to the shoulder, knee and wrist joint such as cartilage tears, tendon tears, carpal tunnel syndrome
Osteoarthritis: A type of arthritis caused by cartilage loss in a joint
Removal of loose bodies: bone or cartilage that becomes logged within the joint
During arthroscopic surgery, either general, spinal, or local anesthesia will be given depending on the condition. These options can be discussed with the Anesthesiologist the day of surgery. A small incision, the size of a buttonhole, is made through which the arthroscope is inserted. Other accessory incisions will be made through which specially designed instruments are inserted. After the procedure is completed, the arthroscope is removed and the incisions are closed. You will be given instructions about incision care, activities to be avoided, and exercises to be performed for optimal recovery. Some of the possible complications after arthroscopy include infection, phlebitis (clotting of blood in vein), excessive swelling, bleeding, blood vessel or nerve damage, and instrument breakage.
It may take several weeks for the puncture wounds to heal and the joint to recover completely. A rehabilitation program may be advised to recover normal joint function. Normal activities may be resumed within a few days after you’re cleared by Dr. DiFelice.
What is Knee Arthroscopy?
Knee Arthroscopy is a common surgical procedure performed using an arthroscope, a viewing instrument, to diagnose or treat a knee problem. It is a relatively safe procedure and most of the patients are discharged from the hospital on the same day of surgery.
Risks & Complications
Indications for Knee Arthroscopy
The knee joint is vulnerable to a variety of injuries. The most common knee problems where knee arthroscopy may be recommended for diagnosis and treatment are:
Torn or damaged cruciate ligament
Torn pieces of articular cartilage
Inflamed synovial tissue
Misalignment of patella
Baker’s cyst: a fluid- filled cyst that develops at the back of the knee due to the accumulation of synovial fluid. It commonly occurs with knee conditions such as meniscal tear, knee arthritis and rheumatoid arthritis.
Certain fractures of the knee bones
Knee Arthroscopy Procedure
Knee arthroscopy is performed under local, spinal or general anesthesia. Your anesthesiologist will decide the best method for you depending on your age and health condition.
The surgeon makes two or three small incisions around the knee.
Next, a sterile saline solution is injected into the knee to push apart the various internal structures. This provides a clear view and more room for the surgeon to work.
An arthroscope, a narrow tube with a tiny video camera on the end, is inserted through one of the incisions to view the knee joint. The structures inside the knee are visible to the surgeon on a video monitor in the operating room.
The surgeon first examines the structures inside the knee joint to assess the cause of the problem.
Once a diagnosis is made, surgical instruments such as scissors, motorized shavers, or lasers are inserted through another small incision, and the repair is performed based on the diagnosis.
The repair procedure may include any of the following:
Removal or repair of a torn meniscus
Reconstruction or repair of a torn cruciate ligament
Removal of small torn pieces of articular cartilage
Removal of loose fragments of bones
Removal of inflamed synovial tissue
Removal of Baker’s cyst
Realignment of the patella
Making small holes or microfractures near the damaged cartilage to stimulate cartilage growth
After the repair, the knee joint is carefully examined for bleeding or any other damage.
The saline is then drained from the knee joint.
Finally, the incisions are closed with sutures or steri-strips, and the knee is covered with a sterile dressing.
Postoperative Care Following Knee Arthroscopy
Most patients are discharged the same day after knee arthroscopy. Recovery after the surgery depends on the type of repair procedure performed. Recovery from simple procedures is often fast. However, recovery from complicated procedures takes a little longer. Recovery from knee arthroscopy is much faster than that from an open knee surgery.
Pain medicines are prescribed to manage pain. Crutches or a knee brace may be recommended for several weeks. A rehabilitation program may also be advised for a successful recovery. Therapeutic exercises aim to restore motion and strengthen the muscles of the leg and knee.
Risks & Complications
Risks and Complications of Knee Arthroscopy
Knee arthroscopy is a safe procedure and complications are very rare. Complications specific to knee arthroscopy include bleeding in the knee joint, infection, knee stiffness, blood clots or continuing knee problems.
What is Shoulder Arthroscopy?
Arthroscopy is a minimally invasive diagnostic and surgical procedure performed for joint problems. Shoulder arthroscopy is performed using a pencil-sized instrument called an arthroscope. The arthroscope consists of a light system and camera to project images onto a computer screen for your surgeon to view the surgical site. Arthroscopy is used to treat disease conditions and injuries involving the bones, cartilage, tendons, ligaments, and muscles of the shoulder joint.
Risks & Complications
Indications of Shoulder Arthroscopy
Shoulder arthroscopy is indicated to treat the following shoulder conditions when conservative treatment, such as medication and therapy, fails to relieve pain and disability:
Shoulder Impingement: this occurs when the shoulder blade applies pressure on the underlying soft tissues when the arm is lifted
Rotator cuff tear
Frozen shoulder or stiffness of the shoulder joint
Shoulder Instability: this occurs when the head of the upper arm bone slips out of the socket of the shoulder blade’s glenoid cavity either due to injury or overuse
Biceps rupture occurs when the tendons attaching the bicep muscle to the shoulder or elbow tears
Damaged cartilage or ligaments
Bone spurs or bony projections
Arthritis of the collarbone
Shoulder Arthroscopy Procedure
Your surgeon performs shoulder arthroscopy under general or regional anesthesia. You may be positioned lying down on your side with your arm propped up or sitting in a semi-seated position. Sterile fluid is injected into the shoulder joint to expand the surgical area so your surgeon has a clear view of the damage and room to work. A button-sized hole is made in the shoulder and the arthroscope is inserted. Your surgeon can view images captured by the camera in the arthroscope on a large monitor. Surgical instruments are introduced into the joint through separate small holes to remove and repair the damage to the joint. After surgery, the instruments are removed and the incisions are closed with stitches or small sterile bandage strips.
Postoperative Care for Shoulder Arthroscopy
After the surgery, the small surgical wounds take a few days to heal and simple adhesive bandages replace the surgical dressing. The recovery time depends on the type and extent of problem for which the procedure was performed. Pain medications are prescribed to keep you comfortable. The arm of the affected shoulder is placed in a sling for a short period as recommended by your doctor. Physical therapy is advised to improve shoulder mobility and strength after the surgery.
Advantages of Shoulder Arthroscopy
The advantages of arthroscopy compared to open surgery with a large incision include:
Shorter hospital stay
Risks & Complications
Risks and complications of Shoulder Arthroscopy
Complications of shoulder arthroscopy include infection, bleeding, damage to nearby nerves or blood vessels, or delayed healing after the surgery. In certain cases, stiffness of the shoulder joint may occur after the surgery. It is important to participate actively in your physical therapy to prevent this from occurring.
