What is Knee Arthroscopic Surgery?

Knee arthroscopic surgery is a minimally invasive surgical technique used to diagnose and treat problems within the knee joint. It involves the use of a small camera, called an arthroscope, which is inserted into the knee through small incisions, often referred to as keyholes. This allows the surgeon to visualize the interior of the knee joint on a monitor and perform necessary surgical procedures with precision.

Indications for Knee Arthroscopy

Knee arthroscopy is utilized for a variety of knee joint issues, including:

  1. ACL (Anterior Cruciate Ligament) Tear : Repair or reconstruction of a torn ACL, which is crucial for stabilizing the knee.
  2. PCL (Posterior Cruciate Ligament) Tear : Addressing injuries to the PCL, another important stabilizing ligament.
  3. Meniscus Tear : Repairing or removing damaged meniscal cartilage, which acts as a cushion between the thigh bone (femur) and shin bone (tibia).
  4. Cartilage Damage : Treating areas of cartilage loss, which can lead to arthritis if left untreated.
  5. Fracture Fixation : Assisting in the repair of fractures within the knee joint.
  6. Synovitis : Removing inflamed synovial tissue, which can cause pain and swelling.

Procedure Overview

The knee arthroscopy procedure typically involves the following steps:

    • Anesthesia : The patient is administered either local, regional, or general anesthesia.
    • Incisions : Small incisions, usually about 1 centimeter each, are made around the knee.
    • Insertion of Arthroscope : The arthroscope is inserted through one of the incisions, providing a clear view of the inside of the knee.
    • Surgical Instruments : Additional small instruments are inserted through other incisions to perform the necessary repairs or removals.
    • Closure : Once the procedure is complete, the instruments are removed, and the incisions are closed with sutures or steri-strips.

Benefits of Knee Arthroscopy

Knee arthroscopy offers several advantages over traditional open knee surgery:

    • Minimally Invasive : Smaller incisions mean less tissue damage and minimal scarring.
    • Reduced Blood Loss : The small incisions and precise nature of the surgery result in less bleeding.
    • Faster Recovery : Patients generally experience quicker recovery times compared to open surgery.
    • Less Pain : The minimally invasive approach usually leads to less postoperative pain.
    • Lower Risk of Infection : Smaller incisions reduce the risk of infection.
    • Outpatient Procedure : Many arthroscopic surgeries are performed on an outpatient basis, allowing patients to go home the same day.

Postoperative Care and Recovery

After knee arthroscopic surgery, patients are typically advised to:

  • Rest and Elevate : Keep the leg elevated to reduce swelling.
  • Ice the Knee : Apply ice packs to control swelling and pain.
  • Physical Therapy : Engage in physical therapy to restore knee function and strength.
  • Follow-Up Visits : Attend follow-up appointments to monitor healing and progress.

Most patients can resume normal activities within a few weeks, although full recovery may take several months, depending on the specific procedure and individual patient factors.

In summary, knee arthroscopic surgery is a valuable technique for addressing a variety of knee joint problems with minimal invasiveness, leading to quicker recovery and a faster return to daily activities.
