Overview
Arthroscopic debridement is a surgical procedure that uses a small camera and specialised instruments to remove damaged tissue from a joint. The procedure is typically performed on the knee but can also be done on the shoulder, elbow, ankle, or hip. A minimally invasive procedure, arthroscopic debridement can be performed on an outpatient basis under general or regional anaesthesia. The procedure uses a tiny camera called an arthroscope; it is inserted into the joint through a small incision. The camera projects images of the joint inside on a monitor, allowing the surgeon to see and remove the damaged tissue.
Types of Arthroscopic Debridement
Depending on the joint and the type of damage being treated, there are several different types of arthroscopic debridement. These include the following:
- Arthroscopic Meniscectomy: This procedure removes a damaged meniscus and a cartilage pad cushioning the knee joint. A damaged meniscus can cause pain, swelling, and difficulty with knee movement. Small instruments are used to remove the meniscus's damaged portion.
- Arthroscopic Chondroplasty: This procedure is used to smooth rough surfaces of cartilage and remove loose fragments in the knee joint. Cartilage is a smooth, slippery tissue that covers the ends of bones in a joint. Damage to this tissue can cause pain and difficulty with movement.
- Arthroscopic Synovectomy: This procedure removes inflamed synovial tissue, the lining of the joint capsule, in conditions such as rheumatoid arthritis. The arthroscope is inserted through small incisions in the joint, and the surgeon uses tiny instruments to remove the inflamed synovial tissue. This procedure helps reduce pain and improves joint movement.
- Arthroscopic Subacromial Decompression: This procedure removes bone spurs and other debris from the shoulder joint to relieve pain and improve range of motion.
Why is surgery needed?
Arthroscopic debridement relieves pain and improves joint function in patients with osteoarthritis, rheumatoid arthritis, and other degenerative joint conditions. Some reasons why arthroscopic debridement is needed include the following:
- Osteoarthritis: This degenerative joint disease causes the cartilage in the joint to wear down with time. As cartilage wears away, bone rubs against bone, causing pain and stiffness. Arthroscopic debridement can remove damaged cartilage, and bone spurs from the joint to relieve pain and improve joint function.
- Rheumatoid Arthritis: This autoimmune condition causes inflammation in the joint lining and leads to pain and stiffness. Arthroscopic debridement can remove inflamed synovial tissue and other debris from the joint.
- Trauma: Injuries such as fractures, dislocations, and ligament tears can cause damage to the joint and surrounding tissue. The procedure can remove damaged or loose tissue and repair or replace damaged structures.
- Tendinitis: Inflamed tendons can cause pain and difficulty with movement. Arthroscopic debridement can be used to remove damaged or inflamed tissue and repair any tears in the tendons.
- Bursitis: Refers to the inflammation of the bursae (fluid-filled sacs that cushion the joint), which can cause pain to the patient. Arthroscopic debridement can remove any inflamed or damaged tissue from the bursa.
- Chondromalacia Patella: Knee cartilage damage, often caused by overuse, can also be treated by arthroscopic debridement.
Indications of Arthroscopic Debridement
The indications for arthroscopic debridement are as follows:
- Acute effusion
- Localised joint line tenderness.
- Locking or catching sensation in the knee.
- History of a specific injury that caused these symptoms.
- Imaging studies confirm the presence of loose bodies in the joint.
- Earlier stages of degenerative joint disease.
- A realistic understanding of the goal of arthroscopy, which is to diminish pain and improve function, not to cure arthritis.
It is essential to note that patient selection criteria are crucial to determining the suitability of arthroscopic debridement for each patient. A thorough evaluation and assessment by an experienced orthopaedic surgeon are necessary to determine the candidacy of a patient.
Who is Not an Ideal Candidate for Arthroscopic Debridement?
This procedure may not be ideal for individuals with the following conditions:
- Advanced Joint Degeneration: If the joint has significant damage and the patient has already reached an advanced stage of osteoarthritis, arthroscopic debridement may not provide significant benefit.
- Previous Joint Replacement: Individuals who have already had joint replacement surgery are not ideal candidates for arthroscopic debridement as it can damage the implant.
- Significant Medical Conditions: Individuals with significant medical conditions, such as heart or lung disease, may not be able to undergo the procedure safely.
- Obesity: Obesity can increase the risk of complications during and after the surgery.
- Smoking: Smoking decreases blood flow to the joint and increases the risk of complications after the surgery.
Surgery Preparation
- Inform the doctor of any prescription drugs, over-the-counter medications, or herbal medicines that the patient is taking.
- Stop taking nonsteroidal anti-inflammatory drugs before surgery.
- The day before the surgery, do not consume any solids or liquids after midnight.
- If the surgeon or doctor has prescribed pain medication after surgery, fill it out the day before.
Surgery Procedure
A step-by-step explanation of the arthroscopic debridement surgery procedure:
- Anesthesia: The patient will be given local, regional, or general anaesthesia. This will depend on the overall complexity of the case and the patient's overall health. This is done to ensure that the patient is comfortable and pain-free during the procedure.
- Incision and Arthroscope Insertion: Once the anaesthesia has taken effect, the orthopaedic surgeon will make a small incision near the joint that needs to be treated. Through this incision, the arthroscope is inserted into the joint. The arthroscope is connected to a monitor, which allows the surgeon to have a clear view of the joint interior.
- Joint Inspection and Fluid Injection: Sterile fluid is injected into the joint to expand the joint space and improve visibility. The arthroscope is then used to inspect the joint, including the cartilage, ligaments, tendons, and other structures. The surgeon carefully examines the joint to identify abnormalities, such as loose bodies, damaged tissue, or inflammation.
- Debridement: Once the surgeon has identified the areas that require treatment, small surgical instruments are inserted through additional small incisions around the joint. These instruments are used to remove or repair damaged tissue or structures. Debridement may involve removing loose bodies, smoothing rough or damaged cartilage, trimming torn or frayed ligaments, or removing inflamed synovial tissue.
- Rinse and Visualisation: Throughout the procedure, the joint is continuously rinsed with sterile fluid to remove debris and provide a clear view. The arthroscope is used to visualise the joint structures and ensure that all the necessary repairs or removals have been completed.
- Closure: Once the debridement is complete, the surgeon will remove the arthroscope and close the incisions with either sutures or adhesive strips. A compression bandage may be applied to the joint to help reduce swelling and provide support.
- Postoperative Care: The patient can usually go home on the same day after the surgery. However, a caregiver may be needed for the first day to assist with mobility and activities of daily living. The patient will be instructed to elevate and ice the operated joint to reduce swelling and manage pain. Dressings over the incision sites may need to be changed regularly.
The patient must follow their surgeon's instructions for physical therapy and exercise to improve muscle strength and range of motion around the joint.
Techniques of Arthroscopic Debridement
Several techniques can be employed during arthroscopic debridement, depending on the condition being treated and the surgeon's preferences.
- Lavage and Irrigation: One of the initial steps in arthroscopic debridement is to flush the joint with sterile fluid to create a clear visual field. This process, known as lavage and irrigation, involves using a specialised fluid pump and irrigation system to remove debris, loose bodies, and inflammatory substances from the joint. Lavage and irrigation can help improve the surgeon's visualisation of the joint and facilitate subsequent surgical steps.
- Mechanical Debridement: Mechanical debridement involves using specialised arthroscopic instruments to remove diseased or damaged tissue from the joint. These instruments may include shavers, burrs, or abraders, which shave or abrade damaged cartilage, synovium, or bone. Mechanical debridement can smooth rough joint surfaces, remove unstable or detached cartilage, or address osteoarthritis, synovitis, or chondromalacia.
- Thermal Debridement: Thermal debridement involves using heat energy to remove or shrink abnormal tissue within the joint. This technique can be achieved using specialised arthroscopic devices such as radiofrequency probes or lasers. Thermal debridement can remove hypertrophic synovium, shrink unstable cartilage, or address conditions such as synovial chondromatosis or plica syndrome.
- Debridement of Loose Bodies: Loose bodies, fragments of cartilage or bone that may float freely within the joint, can cause pain, inflammation, and mechanical symptoms such as catching or locking. Arthroscopic debridement can remove these loose bodies using specialised instruments such as graspers or forceps. The surgeon can visualise the loose bodies using the arthroscope and then use the instruments to safely remove them, alleviating the symptoms caused by their presence.
- Microfracture: Microfracture is used during arthroscopic debridement to address small areas of articular cartilage damage. It involves creating small perforations or "microfractures" in the underlying bone using a specialised awl or pick. This creates a bleeding response, stimulating the formation of a fibrocartilage-like tissue to fill the defect. Microfracture can treat minor cartilage defects and promote healing in areas where the cartilage is damaged or missing.
- Other Techniques: Other techniques may be used during arthroscopic debridement depending on the specific joint condition being treated. For example, the surgeon may use specialised instruments to repair or remove the damaged tissue in ligament or meniscal tears. In cases of infection, the joint may be thoroughly irrigated and debrided to remove infected tissue. The techniques used during arthroscopic debridement will vary depending on the patient's condition and the surgeon's expertise.
Complications of Arthroscopic Debridement
The risk of complications with arthroscopic debridement include:
- Infection: There is a small risk of infection at the surgical site or in the wound.
- Bleeding: There may be some bleeding during or after the procedure.
- Nerve or Blood Vessel Injury: A small risk of injury to nerves or blood vessels near the joint.
- Stiffness: The joint may be stiff and take some time to regain full range of motion.
- Failure to Relieve Symptoms: In some cases, the procedure may not relieve pain or improve joint function.
After Care of Arthroscopic Debridement
After arthroscopic debridement surgery, specific steps that need to be taken to ensure proper healing and recovery are:
- Rest and Elevation: The joint should be kept elevated to reduce swelling and promote healing.
- Physical Therapy: Physical therapy helps improve the range of motion and muscle strength and reduces pain and stiffness.
- Ice and Heat Therapy: Ice packs can be applied to the joint to reduce swelling, while heat therapy can help to alleviate stiffness and soreness.
- Wear a Brace or Splint: Depending on the area of surgery, wearing a brace or splint to immobilise the joint and protect it during the healing process may be necessary.
- Avoid Certain Activities: Activities that stress the joint, such as running and jumping, should be avoided until the joint has fully healed.
- Weight Management: Maintaining a healthy weight can help reduce the pressure on the joint and promote healing.
Recovery time varies depending on the patient's overall health, the type of procedure performed and the extent of the damage.
Outlook of Arthroscopic Debridement
The outlook for patients undergoing arthroscopic debridement is generally positive. The procedure is minimally invasive, and most patients may return to normal activities within a few weeks.
Recovery time and success depend on the severity of the joint damage and the patient's adherence to postoperative instructions and physical therapy. However, some patients may still experience pain or limited mobility after surgery.
