Arthroscopic Medial Meniscal Repair

The medial meniscus is a C-shaped cartilage structure on the inner side of the knee that cushions the joint, distributes weight, and provides stability between the thighbone (femur) and shinbone (tibia). When torn, the meniscus loses its ability to protect the knee, leading to pain, swelling, locking, and reduced mobility. These injuries often occur during sports activities, twisting motions, or as part of age-related degeneration.

Rather than removing the damaged tissue, arthroscopic medial meniscal repair focuses on restoring the meniscus to its natural form. Preserving the meniscus is crucial—it reduces the risk of arthritis, maintains joint biomechanics, and prolongs long-term knee health.

When Arthroscopic Meniscal Repair Is Recommended

Not every meniscal tear requires surgery. However, arthroscopic repair is often chosen when:

The tear occurs in the outer vascular zone, where blood supply supports healing.
The patient is young, active, or athletic and needs a strong, stable knee.
The tear is large, unstable, or symptomatic despite non-surgical treatments.
The meniscus injury is combined with an ACL tear or ligament damage, allowing simultaneous repair.

Arthroscopic Surgical Procedure

Evaluation and Diagnosis
A detailed clinical exam and MRI scan confirm the tear’s size, type, and location.
Anesthesia and Preparation
The patient receives anesthesia, and the knee is painted and positioned for precise arthroscopic access.
Arthroscopic Repair
Through tiny incisions, a camera (arthroscope) and specialized instruments are introduced. The torn edges of the meniscus are repositioned and secured with sutures or anchors. Techniques such as inside-out, outside-in, or all-inside repair are selected depending on the tear’s pattern and position.
Concurrent Repairs (if needed)
If other injuries, such as ACL tears, are present, they are repaired during the same arthroscopic session.
Closure and Dressing
The small keyhole incisions are closed, and the knee is protected with a sterile bandage and brace.

Recovery and Rehabilitation

Rehabilitation after arthroscopic medial meniscal repair is structured to protect healing and restore strength:

Immobilization: A knee brace limits excessive movement during the early healing stage.
Weight-Bearing Control: Crutches are typically required for several weeks until the repair is stable. Non weight bearing walk uptill 4 weeks.
Physiotherapy: Gradual progression from gentle range-of-motion exercises to strengthening of the quadriceps, hamstrings, and hip muscles.
Return to Sports: Most patients safely resume sports within 4–6 months, depending on healing progress and adherence to therapy.

Benefits of Arthroscopic Meniscal Preservation

Maintains the knee’s natural cushioning and stability.
Reduces the likelihood of early osteoarthritis.
Improves long-term function and mobility.
Lowers the risk of requiring future knee replacement surgery.

Risks and Considerations

Although generally safe, arthroscopic meniscal repair carries some risks, including stiffness, incomplete healing, infection, or re-tear of the repaired tissue. Success rates are highest in patients who carefully follow rehabilitation protocols and allow sufficient healing time before returning to strenuous activity.

Summary

arthroscopic medial meniscal repair is a minimally invasive and highly effective procedure that restores stability, preserves joint function, and protects long-term knee health. By saving the meniscus instead of removing it, patients enjoy better mobility, reduced risk of arthritis, and a stronger foundation for an active lifestyle.

Frequently Asked Questions

Common questions about Arthroscopic Medial Meniscal Repair and our services

Arthroscopic repair of the medial meniscus is a minimally invasive surgical procedure used to fix tears in the inner cartilage of the knee. Small incisions allow the surgeon to insert a tiny camera and surgical instruments to remove damaged tissue or suture the torn meniscus. This technique preserves healthy cartilage, reduces post-operative pain, and speeds up recovery. Patients typically experience improved knee stability, reduced pain, and better mobility while minimizing risks compared to traditional open surgery.

The recovery time for arthroscopic medial meniscus repair generally ranges from 4 to 6 weeks for basic activities, with full recovery taking 3 to 6 months. Early post-operative care includes rest, ice, and limited weight-bearing to protect the repair. Physiotherapy begins soon after surgery to restore motion, strengthen surrounding muscles, and improve stability. Following the surgeon’s guidance and rehabilitation plan ensures safe healing and allows patients to return to sports or daily activities with minimal risk of re-injury

Yes, most patients can walk after arthroscopic meniscus surgery, often with the help of crutches or a walker initially. Weight-bearing is gradually increased as recommended by the surgeon, depending on the type and extent of the repair. Early gentle movement promotes healing, reduces stiffness, and prevents muscle weakening. Physiotherapy plays a vital role in restoring knee strength, flexibility, and balance. Within a few weeks, many patients are able to walk comfortably and resume light daily activities safely.
