Arthroscopic Meniscus Surgery


Arthroscopic meniscus surgery is a minimally invasive procedure used to diagnose and treat injuries to the meniscus, the C-shaped cartilage that cushions and stabilizes the knee joint. The surgery involves the use of an arthroscope, a small camera that allows the surgeon to view the inside of the knee on a monitor and perform the necessary repairs through tiny incisions.

Procedure Of Arthroscopic Meniscus Surgery

Preoperative Preparation

  • Evaluation: The patient undergoes a thorough clinical evaluation, including physical examination and imaging studies like MRI, to confirm the diagnosis and plan the surgery.
  • Preparation: Patients are given specific preoperative instructions, such as fasting and medication adjustments, to ensure safety during surgery.


  • The procedure is usually performed under regional or general anesthesia, depending on the patient’s condition and preference.

Surgical Steps

  • Incisions: Small incisions, typically less than an inch, are made around the knee.
  • Arthroscope Insertion: The arthroscope is inserted through one of the incisions, providing a clear view of the knee joint on a monitor.
  • Repair or Removal: Depending on the type and extent of the meniscus injury, the surgeon will either repair the torn meniscus using sutures or remove the damaged portion (partial meniscectomy).
  • Closure: The incisions are closed with sutures or surgical tape and covered with a sterile dressing.

Postoperative Care

  • Recovery: Patients typically go home the same day. Postoperative care includes rest, ice application, compression, and elevation (RICE protocol) to reduce swelling and pain.
  • Rehabilitation: A structured physical therapy program is initiated to restore knee function, strength, and mobility.
  • Follow-Up: Regular follow-up visits with the surgeon are essential to monitor healing and progress.

Advantages of Meniscus Repair Surgery

Meniscus repair surgery offers several benefits over meniscectomy (removal of the meniscus), particularly for younger patients and those with tears that are repairable. Here are the key advantages:

  • Preservation of Knee Function

Natural Shock Absorption: The meniscus acts as a shock absorber in the knee joint, distributing load and reducing stress on the articular cartilage. Repairing rather than removing the meniscus helps maintain its natural function.

  • Reduced Risk of Osteoarthritis

Joint Protection: By preserving the meniscus, the risk of developing osteoarthritis later in life is significantly reduced. The meniscus plays a crucial role in protecting the articular cartilage from wear and tear.

  • Better Long-Term Outcomes

Sustained Knee Health: Patients who undergo meniscus repair tend to have better long-term outcomes, including sustained knee stability and function, compared to those who have the meniscus removed.

  • Faster Recovery and Rehabilitation

Minimally Invasive: Arthroscopic meniscus repair is minimally invasive, resulting in smaller incisions, less postoperative pain, and quicker recovery compared to open surgery.

  • Enhanced Athletic Performance

Return to Sports: Athletes and active individuals benefit from meniscus repair as it allows for a quicker and more effective return to sports and physical activities without compromising knee integrity.

Why Preserve the Meniscus of the Knee Joint

Preserving the meniscus is crucial for maintaining knee joint health and function. Here are the main reasons why preserving the meniscus is important:
  • Maintaining Joint Stability: The meniscus provides essential structural support to the knee joint, helping to stabilize the knee during movement and reducing the risk of further injury.
  • Improving Biomechanics: The meniscus evenly distributes the load across the knee joint, ensuring smooth and efficient movement. Preserving the meniscus maintains optimal knee biomechanics.
  • Protecting Cartilage: The meniscus protects the articular cartilage by reducing friction and wear within the joint. Preservation helps prevent cartilage degradation and the onset of arthritis.
  • Enhancing Knee Function: A healthy meniscus contributes to a full range of motion in the knee. Preserving the meniscus ensures better flexibility and functional performance of the joint.
  • Preventing Degenerative Changes: Removing the meniscus can lead to degenerative changes in the knee, including osteoarthritis. Preservation reduces the likelihood of these long-term issues, promoting overall joint health.
  • Optimizing Recovery: Meniscus repair promotes natural healing and regeneration of the tissue, leading to a more sustainable recovery and better outcomes compared to removal.


Arthroscopic meniscus surgery, particularly meniscus repair, offers significant benefits for maintaining knee health, functionality, and long-term joint integrity. Preserving the meniscus is vital for protecting the knee from degenerative changes and ensuring optimal performance in daily activities and sports. If you have a meniscus injury, consult with a specialized orthopedic surgeon to explore the best treatment options for preserving and restoring your knee joint.
