Meniscus Repair
Meniscus repair is a minimally invasive procedure used to fix tears in the knee’s cushioning cartilage (meniscus). A small camera (arthroscope) and specialised surgical tools are inserted through small incisions to view and repair the tear. This method is preferred over removing the damaged cartilage, as it helps preserve knee function and reduces the risk of arthritis. Meniscus repair is most effective for tears in areas with good blood supply, such as the outer edge of the meniscus (the ‘red zone’), which promotes better healing.

Indications for Meniscus Repair
Meniscus repair is recommended for individuals with specific types of meniscal injuries that cannot be effectively treated through conservative methods. Common indications include:
- Traumatic Meniscus Tears: These can result from injuries caused by sudden trauma, which are frequently associated with sports or accidents. These tears are typically located in the outer region of the meniscus.
- Degenerative Meniscus Tears: These occur due to gradual wear and tear, typically in older adults. Surgery may be indicated if the tear causes persistent pain, swelling, or functional limitations.
- Unstable or Displaced Tears: When a meniscus tear, such as a bucket-handle tear, causes knee instability or leads to the displacement of a meniscus fragment, surgery may be necessary to repair and reattach the torn tissue.
Benefits of Meniscus Repair
Meniscus repair offers multiple advantages that enhance knee health and support an active lifestyle.
Preservation of Knee Function
Repairing the meniscus helps maintain its natural structure, which is necessary for proper knee function. This preservation supports the knee’s ability to absorb shock and stabilise the joint during movement.
Reduced Risk of Arthritis
By preserving the meniscus, the procedure reduces the risk of knee osteoarthritis. Removing the meniscus can lead to increased stress on the knee joint, accelerating degenerative changes over time.
Improved Healing Potential
Meniscus repair, especially in the vascular (red zone), has a higher chance of healing effectively due to the blood supply in that area. This results in better long-term outcomes than meniscectomy (meniscus removal).
Preparing for Meniscus Repair
Proper preparation is required for a smooth and successful meniscus repair. Key steps include:
- Medical Evaluation
A thorough health assessment is performed to ensure that you are fit for surgery. This includes reviewing medical history and any existing medical conditions that may affect the surgery or recovery. - Imaging Tests
Imaging tests are required to diagnose the extent of a meniscal tear. X-rays help rule out fractures, while MRI provides detailed images of the meniscus and surrounding tissues to assess the tear’s size and location. Ultrasound may also be used for real-time imaging of the knee joint. - Medication Adjustments
You may need to adjust or temporarily discontinue certain medications, especially blood thinners and anti-inflammatory drugs, to minimise the risk of bleeding during and after the procedure. - Fasting
Fasting is typically required for 8 to 12 hours before surgery to ensure an empty stomach for anaesthesia and to minimise complications such as aspiration.
Step-by-Step Procedure
Here’s what to expect during meniscus repair surgery, highlighting each key phase of the process.
Administration of Anaesthesia
General anaesthesia will be used to keep you unconscious during the procedure. In some cases, regional anaesthesia is an option, where the lower body is numbed but the patient remains awake.
Making Incisions
The surgeon will make several small incisions around the knee, typically 0.5 to 1 cm in length, to insert the arthroscope and specialised surgical tools. The number and placement of these incisions depend on the complexity of the repair.
Surgical Procedure
The arthroscope provides a magnified view of the knee joint on a monitor, allowing the surgeon to accurately assess and locate the tear. Specialised tools are used to repair the meniscus, typically by suturing the torn edges together. The exact technique depends on the location and type of tear.
Completion and Incision Closure
After the repair, the instruments and arthroscope are removed. The incisions are closed with sutures or surgical tape, and a bandage is applied to protect the area.
Post-Surgical Care and Recovery
Proper post-operative care is necessary for a smooth recovery and optimal healing after meniscus repair, with recovery times varying based on the severity of the tear.
Immediate Care
After surgery, patients are monitored in a recovery area while waking from anaesthesia. Vital signs (blood pressure, heart rate, and oxygen levels) are closely checked. Mild discomfort, pain, or swelling around the knee is common and can be managed with prescribed pain medication. Nausea from anaesthesia may occur but typically subsides as its effects wear off.
Recovery Process
Most patients are discharged the same day or within 24 hours, depending on the complexity of the surgery and their health. Light activities like walking are encouraged within a few days to promote circulation and prevent stiffness. The first week should focus on rest and avoiding strenuous activity. Gradual resumption of daily tasks usually begins during weeks 2 to 4, with restrictions on heavy lifting and high-impact activities for at least 4 to 6 weeks. Most patients can resume normal activity 4 to 6 months after surgery, though individual recovery times may vary.
Potential Risks and Complications
Meniscus repair is generally safe, but risks include infection (leading to redness, swelling, or pain), minor bleeding, and rare severe bleeding that may require treatment. Blood clots, particularly deep vein thrombosis, can occur but are usually prevented through early mobilisation or anticoagulant medications. Rarely, nerve or blood vessel damage may result in numbness or circulation issues. The meniscus may not heal properly or could tear again, potentially necessitating further surgery.

Frequently Asked Questions (FAQs)
Can I kneel or squat after the meniscus repair?
While you can eventually kneel and squat after meniscus repair, it is important to avoid them during the initial recovery period. These actions place significant strain on the knee, which can compromise healing. Your physical therapist will guide you on when to safely reintroduce these movements, usually after several months of rehabilitation.
Can a meniscus tear heal on its own without surgery?
Some small meniscus tears, particularly those in the outer part (the ‘red zone’) with good blood supply, may heal on their own with rest, physical therapy, and non-surgical treatments. However, larger or more severe tears often require surgical intervention, especially if they cause pain, instability, or limit mobility.
Are there activities I should avoid permanently after meniscus repair?
While many patients return to their normal activities, some high-impact sports or activities that put excessive strain on the knee may need to be limited long term. Consult with your surgeon about any specific restrictions based on your recovery.
