Knee Arthroscopy

Knee arthroscopy is a minimally invasive surgical procedure that involves the use of a small camera, called an arthroscope, to examine and treat various conditions affecting the knee joint. This procedure allows orthopedic surgeons to visualize the inside of the knee and perform certain surgical interventions through small incisions, rather than the larger incisions required in traditional open surgery. Knee arthroscopy is commonly used for diagnostic purposes as well as the treatment of various knee issues. Here are key aspects of knee arthroscopy:

Diagnostic Arthroscopy:

  • Visualization: The arthroscope is inserted through a small incision, providing a clear view of the structures inside the knee, including the ligaments, cartilage, and menisci.
  • Diagnosis: The surgeon can identify and diagnose conditions such as ligament tears, meniscal injuries, cartilage damage, and inflammation.

Therapeutic Arthroscopy:

  • Treatment: In addition to diagnosis, knee arthroscopy allows for the performance of various surgical procedures to treat specific conditions.
  • Tissue Removal: Damaged or torn tissues, such as torn meniscal fragments, may be removed or trimmed during the procedure.
  • Ligament Repair or Reconstruction: Arthroscopy can be used for repairing or reconstructing torn ligaments, such as the anterior cruciate ligament (ACL).
  • Cartilage Repair: Techniques such as microfracture or cartilage debridement can be performed to address cartilage injuries.

Procedure Details:

  • Anesthesia: Knee arthroscopy is typically performed under regional or general anesthesia, depending on the specific procedure and patient preference.
  • Incisions: Small incisions, known as portals, are made around the knee to insert the arthroscope and specialized surgical instruments.
  • Fluid Irrigation: A sterile saline solution is used to expand the joint space, providing a clearer view and facilitating surgical maneuvers.

Advantages of Knee Arthroscopy:

  • Minimally Invasive: Compared to open surgery, arthroscopy involves smaller incisions, resulting in less tissue damage and potentially quicker recovery.
  • Faster Healing Time: Patients may experience less postoperative pain and a faster return to normal activities.
  • Reduced Scarring: Smaller incisions generally lead to less noticeable scars.

Recovery and Rehabilitation:

  • Postoperative Care: After knee arthroscopy, patients are given specific instructions for postoperative care, including pain management and wound care.
  • Physical Therapy: Rehabilitation and physical therapy are often recommended to restore strength, flexibility, and functionality of the knee.
  • Return to Activities: The timeline for returning to regular activities varies depending on the type of procedure performed and individual factors.

While knee arthroscopy is a common and generally safe procedure, potential risks and complications, such as infection or blood clots, should be discussed with the surgeon. The decision to undergo knee arthroscopy is based on the specific diagnosis, the severity of the condition, and the patient's overall health.

Knee arthroscopy is a surgical procedure that involves the use of a small camera, called an arthroscope, to examine and treat various problems within the knee joint. It is a minimally invasive technique that allows surgeons to visualize the interior of the knee without making large incisions. Knee arthroscopy may be done for several reasons:

Diagnostic Evaluation:

  • Unexplained Knee Pain: When a patient experiences persistent knee pain without a clear diagnosis, knee arthroscopy allows the surgeon to directly visualize the structures inside the joint to identify the cause of pain.

  • Unexplained Swelling: If the knee is swollen, and the cause is not apparent through non-invasive methods, arthroscopy can provide a direct view of the joint's interior to identify the source of swelling.

  • Joint Locking or Catching: Arthroscopy is used to investigate the cause of symptoms such as joint locking or catching, which may be indicative of a mechanical issue within the knee.

Treatment of Specific Conditions:

  • Cartilage Damage: Arthroscopy can be used to address various cartilage issues, including tears, defects, or general wear and tear. Procedures such as microfracture or cartilage debridement can be performed.

  • Meniscus Tears: Tears in the meniscus, the C-shaped cartilage that cushions the knee joint, can be repaired or trimmed using arthroscopy.

  • Ligament Injuries: Some ligament injuries, such as anterior cruciate ligament (ACL) tears, can be treated through arthroscopic procedures. ACL reconstruction involves replacing the torn ligament with a graft.

  • Synovitis and Inflammation: Arthroscopy can be used to remove inflamed synovial tissue or to address conditions like synovitis.

Removal of Loose Bodies:

Sometimes, fragments of bone or cartilage, known as loose bodies, can break off within the joint and cause pain or interference with movement. Arthroscopy allows for the removal of these loose bodies.

Joint Washout (Lavage):

To remove debris or inflammatory substances from the joint, a surgeon may perform joint lavage during arthroscopy.

Treatment of Knee Infections:

Arthroscopy can be used to drain and wash out the knee joint in cases of infection.

Knee arthroscopy is generally less invasive than traditional open surgery, resulting in smaller incisions, less postoperative pain, and quicker recovery times. However, the decision to undergo knee arthroscopy is based on the specific condition of the patient and the findings of diagnostic evaluations. It's important for individuals considering knee arthroscopy to have a thorough discussion with their orthopedic surgeon to understand the potential benefits, risks, and expected outcomes based on their unique circumstances.

Knee arthroscopy is a common surgical procedure that involves using a small camera (arthroscope) to visualize and treat various conditions within the knee joint. While knee arthroscopy is generally considered safe and has a lower risk profile compared to traditional open surgery, like any medical procedure, it is not without potential risks and complications. Here are some of the risks associated with knee arthroscopy:

  • Infection: Infections can occur at the incision sites or within the joint. The risk is relatively low, but it is still a potential complication. Precautions are taken to minimize the risk of infection, such as using sterile techniques during surgery.
  • Bleeding: Bleeding can occur during or after the surgery, leading to swelling and bruising. Excessive bleeding is rare but may require further medical attention.
  • Blood Clots: There is a small risk of developing blood clots (deep vein thrombosis) following knee arthroscopy. Patients are often encouraged to move their legs and feet after surgery to help prevent clot formation.
  • Nerve or Blood Vessel Damage: While uncommon, there is a risk of injury to nerves or blood vessels around the knee during the surgery, which could lead to numbness, weakness, or other complications.
  • Stiffness or Loss of Range of Motion: Some patients may experience stiffness or a temporary loss of range of motion in the knee following arthroscopy. This is usually addressed through postoperative rehabilitation and physical therapy.
  • Persistent Pain or Swelling: In some cases, patients may continue to experience pain or swelling in the knee after the surgery, which may require further evaluation and intervention.
  • Allergic Reactions: Rarely, individuals may have allergic reactions to medications or materials used during the procedure.
  • Failure to Relieve Symptoms: While knee arthroscopy can be successful in addressing certain conditions, it may not always provide complete relief of symptoms, especially in cases of advanced joint degeneration or complex issues.
  • Instrument Breakage: There is a very low risk of instruments used during the procedure breaking, which could potentially require additional measures to address.
  • Inadequate Diagnosis or Treatment: In some cases, the arthroscopic procedure may not fully reveal the extent of a problem or may not successfully address the issue. Additional surgery may be needed.

It's important for individuals considering knee arthroscopy to have a thorough discussion with their orthopedic surgeon about the potential risks and benefits, as well as alternative treatment options. The decision to undergo knee arthroscopy is made based on the specific condition, the patient's health, and the goals of treatment. Most individuals experience positive outcomes with knee arthroscopy, and the procedure is often associated with a faster recovery compared to traditional open surgery.


Knee arthroscopy is a minimally invasive surgical procedure that allows a surgeon to visualize, diagnose, and treat problems inside the knee joint. It involves the use of a specialized instrument called an arthroscope, which is a thin, flexible tube with a camera attached to it. The arthroscope is inserted into the knee through small incisions, allowing the surgeon to view the interior of the joint on a monitor and perform various procedures. Here is an overview of the knee arthroscopy procedure:


  • Before the surgery, the patient is typically administered either general anesthesia, which puts the patient to sleep, or regional anesthesia, such as a spinal or epidural block, which numbs the lower part of the body.

Incision Placement:

  • The surgeon makes small incisions, usually ranging from ¼ to ½ inch, around the knee. These incisions serve as entry points for the arthroscope and other instruments.

Arthroscopic Inspection:

  • The arthroscope is inserted through one of the incisions into the knee joint. The camera at the end of the arthroscope transmits high-definition images to a monitor in the operating room.

Joint Examination:

  • The surgeon examines various structures within the knee joint, including the cartilage, ligaments, menisci, and synovium. This visual inspection helps diagnose any issues and determine the appropriate course of action.

Treatment or Repair:

  • Depending on the findings, the surgeon may perform various procedures using specialized arthroscopic instruments. Common procedures include:
    • Meniscus Repair or Trimming: Repairing or trimming torn meniscal cartilage.
    • Ligament Reconstruction: Reconstructing torn ligaments, such as the anterior cruciate ligament (ACL).
    • Cartilage Repair: Treating damaged articular cartilage.
    • Removal of Loose Bodies: Extracting loose bone or cartilage fragments.
    • Synovectomy: Removing inflamed synovial tissue.


  • After the necessary procedures are completed, the surgeon removes the arthroscope and other instruments. The small incisions are closed with stitches or adhesive strips.

Recovery and Rehabilitation:

  • The patient is taken to the recovery room, where vital signs are monitored.
  • Physical therapy is typically initiated shortly after the procedure to aid in the recovery process.
  • Most patients can go home on the same day of the surgery, although some may require an overnight stay.

Postoperative Care:

  • Patients are given instructions for postoperative care, including wound care, pain management, and activity restrictions.
  • Follow-up appointments are scheduled to monitor the progress of the knee's healing and address any concerns.

Knee arthroscopy is known for its shorter recovery times and reduced postoperative pain compared to traditional open surgery. However, individual recovery experiences can vary based on the specific procedures performed and the patient's overall health. It's essential for patients to follow their surgeon's postoperative instructions and engage in rehabilitation to optimize recovery and regain full function in the knee.
