Knee Arthroscopy Treatment

Knee arthroscopy has become a commonly performed procedure in orthopedic surgery due to its advantages over traditional open surgery. It allows for smaller incisions, reduced trauma to surrounding tissues, faster recovery times, and potentially less postoperative pain.

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 causing 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 (adhesions) can develop and limit joint 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. It involves using a small camera, called an arthroscope, along with specialized surgical instruments to visualize and address issues within the knee joint. 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).
  • 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: Saline solution is pumped into the knee joint to expand it, creating more space for the surgeon to work. The arthroscope provides a clear view of the various structures within the knee, including the cartilage, ligaments, menisci, and synovial lining
  • 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 be used to 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.
  • Closure: After completing the necessary procedures, the surgeon removes the arthroscope and other instruments. The saline solution is drained from the knee joint, and the incisions are typically closed with stitches or surgical tape.
  • Recovery: The patient is taken to a recovery area, where they are monitored as they wake up from anesthesia. Depending on the complexity of the procedure and the patient's condition, they might be allowed to go home the same day or need to stay in the hospital overnight.
  • Postoperative Care: Patients are provided with instructions on how to care for their knee after the procedure. This often includes guidelines on rest, ice, compression, and elevation (RICE), as well as specific exercises and rehabilitation to aid in recovery and regain strength and mobility.

Who will Treat the knee arthroscopy procedure

Orthopedic surgeon:

A knee arthroscopy procedure is typically performed by an Orthopedic Surgeon who specializes in the treatment of musculoskeletal conditions and injuries, particularly those related to the bones, joints, ligaments, and tendons of the knee. Orthopedic surgeons are medical doctors who have received specialized training in orthopedic surgery and have expertise in performing a variety of surgical procedures, including arthroscopic surgeries.Within the field of orthopedic surgery, there are subspecialists who focus specifically on knee-related issues. These specialists are often referred to as knee surgeons or knee orthopedic surgeons. They have extensive experience in diagnosing and treating a wide range of knee conditions and injuries, and they are well-equipped to perform knee arthroscopy procedures.

Preparing for a knee arthroscopy procedure

  • Consultation and Information Gathering: Attend a preoperative consultation with your orthopedic surgeon. During this visit, you'll discuss the procedure, its benefits, potential risks, and what to expect during the recovery period.
