Quick Facts about Knee Arthroscopy

• Type of Procedure: Minimally invasive surgical procedure.
• Duration: Typically takes about 30 minutes to 1 hour.
• Anesthesia Used: Usually general anesthesia, spinal anesthesia, or local anesthesia with sedation.
• Recovery Time: Most people return to light activities within 1-3 weeks; full recovery may take around 6-8 weeks depending on the procedure done.

Indications for Knee Arthroscopy

It is used to diagnose and treat a range of knee joint conditions, including:

• Meniscus Tears: Tears in the meniscus, the cartilage that cushions the knee joint, often cause pain, swelling, and limited mobility.
• Anterior Cruciate Ligament (ACL) Tears: A common knee injury involving a tear in the ACL, a ligament that stabilizes the knee joint.
• Posterior Cruciate Ligament (PCL) Tears: Tears in the PCL, another ligament that helps stabilize the knee.
• Cartilage Injuries: Damage or defects in the articular cartilage that covers the ends of bones in the knee joint, causing pain and joint dysfunction.
• Synovitis: Inflammation of the synovial membrane lining the knee joint, causing pain, swelling, and stiffness.
• Loose Bodies: Small fragments of bone or cartilage that become dislodged within the joint, causing pain and limited movement.
• Patellar (Kneecap) Disorders: Conditions like patellar chondromalacia (softening of cartilage), which leads to pain behind the kneecap.
• Tendon Injuries: Torn or damaged tendons, such as the patellar tendon or quadriceps tendon.
• Ligament Sprains: Mild to moderate sprains of various knee ligaments.
• Removal of Scar Tissue: After previous knee surgeries or injuries, scar tissue (also known as adhesions) can develop, limiting joint movement.

Preparing for a knee arthroscopy procedure

Getting ready for knee arthroscopy involves a few important steps to ensure a smooth surgery and recovery. Here's what you can expect before the procedure:

• Consultation and Information Gathering: Meet your orthopedic surgeon to discuss the procedure, its benefits, potential risks, and recovery. Ask any questions you may have.
• Medical Evaluation: Your surgeon will likely order various medical tests, such as blood work and possibly imaging tests (X-rays or MRI), to assess your overall health and the condition of your knee joint.
• Preoperative Exercises: Strengthen your knee muscles with the recommended exercises to aid in recovery.
• Arrangements for After Surgery: Arrange for someone to drive you home after the procedure, as the effects of anesthesia might temporarily impair your ability to drive.
• Comfortable Clothing: Wear comfortable, loose-fitting clothing on the day of the procedure. This will make it easier to change into a hospital gown and will be more comfortable afterward.
• Follow Fasting Guidelines: Avoid eating and drinking for a specific time before surgery as instructed.
• Anesthesia Discussion: If you have concerns or questions about anesthesia, discuss them with the anesthesia team during the preoperative visit.
• Follow Instructions: Your surgeon may provide specific instructions regarding medications, dietary restrictions, and other guidelines. Make sure to follow these instructions diligently.
• Mental Preparation: Take a moment to mentally prepare for the procedure. Stay positive and focus on the benefits of the surgery for your long-term knee health.

Who will perform the knee arthroscopy procedure?

A knee arthroscopy is performed by an orthopedic surgeon who specializes in treating musculoskeletal conditions.

• Orthopedic Surgeons: Experts in bone, joint, ligament, and tendon-related conditions.
• Knee Specialists: Some orthopedic surgeons specialize in treating knee injuries and disorders.

These specialists ensure precise treatment for knee conditions, improving recovery and mobility.

Risks and Complications of Knee Arthroscopy

Knee arthroscopy is generally a safe procedure, but like any surgery, it carries some risks. Possible complications include:

• Infection: Although rare, infections can occur at the incision sites or inside the knee joint.
• Bleeding or Blood Clots: Small amounts of bleeding are normal, but serious bleeding or clots can happen in rare cases.
• Swelling and Stiffness: Some swelling and stiffness are common after surgery, but if severe, it may slow down recovery.
• Nerve or Blood Vessel Damage: There's a small risk of injury to nerves or blood vessels near the knee.
• Ongoing Knee Problems: Some people may continue to have knee pain, stiffness, or weakness even after the procedure.
• Reaction to Anesthesia: Some patients may experience minor side effects or, in rare cases, serious reactions to anesthesia.
• Scar Tissue Formation: Excess scar tissue inside the knee can cause stiffness or limit movement.

Steps Involved in Knee Arthroscopy Procedure

Knee arthroscopy is a minimally invasive surgical procedure that allows orthopedic surgeons to diagnose and treat various knee-related conditions. Here are the general steps involved in a knee arthroscopy procedure

• Preparation: Before the procedure, the patient is typically given anesthesia. Depending on the case, this could be local anesthesia (numbing only the knee area) or general anesthesia (making the patient unconscious).
• Small Incisions: The surgeon makes small incisions around the knee to insert the arthroscope and surgical instruments. These incisions are usually less than half an inch in size.
• Arthroscope Insertion: The arthroscope, a thin and flexible fiber-optic camera, is inserted through one of the incisions. This allows the surgeon to view the inside of the knee joint on a monitor.
• Inspection: A saline solution is used to expand the knee for a better view of the cartilage, ligaments, and other structures.
• Diagnosis: The surgeon examines the knee joint to identify any issues, such as torn ligaments, damaged cartilage, inflamed synovium, or loose fragments.
• Treatment: Depending on the findings, the surgeon may perform various procedures to address the issues. Some common procedures include:
• Ligament Repair or Reconstruction: If a ligament (such as the anterior cruciate ligament, ACL) is torn, it may be repaired or reconstructed using sutures or grafts.
• Meniscus Repair or Trimming: Torn sections of the meniscus (c-shaped cartilage) may be repaired using sutures or removed through a procedure called meniscectomy.
• Cartilage Repair: Techniques such as microfracture, drilling, or cartilage transplantation might stimulate the growth of new cartilage in damaged areas.
• Synovial Tissue Removal: If the synovium is inflamed (synovitis), it may be removed to alleviate symptoms.
• Loose Body Removal: Any loose bone fragments or cartilage that could cause pain or interfere with joint movement are removed.
• Post-operative Care: After the procedure, you will receive guidelines for resting, icing, compressing, and elevating your knee (RICE method), along with a rehabilitation plan.
