What Is Meniscal Repair?

Meniscal repair is knee surgery that sutures or anchors a torn meniscus so the tissue can heal rather than being removed. The medial and lateral menisci are crescent-shaped fibrocartilage structures that distribute load, absorb shock, and contribute to knee stability. Repair preserves more meniscal tissue than partial meniscectomy and can reduce the long-term loss of joint protection associated with tissue removal. The procedure is most commonly performed arthroscopically through small incisions around the knee.

Why Is Meniscal Repair Performed?

The procedure is used for meniscal tears that have a reasonable chance of healing and cause persistent pain, locking, instability, or functional limitation. Tears in the more vascular outer portion of the meniscus, acute longitudinal tears, and selected radial or root tears are more likely to be considered for repair. Surgeons also consider age, tear pattern, tissue quality, knee alignment, cartilage health, activity goals, and associated ligament injuries. Degenerative or poorly vascularized tears that cannot hold sutures can require trimming rather than repair.

How Is Meniscal Repair Performed?

The surgeon inserts an arthroscope into the knee and examines the tear pattern, location, tissue quality, and surrounding cartilage. Repairable tissue is prepared to stimulate healing and is secured with sutures using all-inside, inside-out, or outside-in techniques depending on tear location. Meniscal root tears can require bone tunnels through the tibia so the root can be anchored back near its normal attachment. Associated anterior cruciate ligament reconstruction or other knee procedures can be performed during the same operation when indicated.

What Is Recovery Like After Meniscal Repair?

Recovery is slower than after partial meniscectomy because the repaired meniscus needs time to heal. Crutches, a brace, protected weight-bearing, or limits on knee flexion can be required depending on the tear and repair technique. Range of motion and strengthening are progressed gradually through physical therapy, with root repairs generally requiring more protection. Many patients return to normal activity around six months, while return to higher-level sports can take longer.

What Are the Risks and Complications?

Possible complications include infection, blood clots, knee stiffness, muscle weakness, nerve or blood-vessel injury, and persistent pain. The repaired meniscus can fail to heal or can tear again after a new injury. Failed repair can require repeat meniscal repair or partial meniscectomy. Long-term outcome also depends on knee alignment, cartilage health, ligament stability, rehabilitation, and the original tear pattern.

Frequently Asked Questions About Meniscal Repair

Why repair a meniscus instead of removing the torn part?

Repair preserves more meniscal tissue, which helps maintain load distribution and joint protection and can reduce the risk of early osteoarthritis compared with removing repairable tissue.

Which meniscus tears can be repaired?

Repair is most successful for selected tears with good tissue quality and healing potential, including many peripheral longitudinal tears and some radial or root tears.

How long does recovery take after meniscal repair?

Rehabilitation commonly lasts several months. The American Academy of Orthopaedic Surgeons notes that return to normal activity is often around six months after repair.

Can a repaired meniscus tear again?

Yes. The tissue can fail to heal or can be reinjured later. Additional arthroscopy can be needed when pain, locking, or recurrent tearing persists.
