Meniscus Repair Surgery

How Effective is the Treatment?

The success of meniscus repair surgery depends on several factors, including the type and location of the tear, patient characteristics, and adherence to post-operative care. Here's a detailed look at the effectiveness of this treatment:

Success Rates

• General Success: Meniscus repair has a success rate of 70% to 90%, depending on the tear type and location.
• Higher Success in the Red Zone: Tears in the outer third of the meniscus, known as the "red zone," have a better healing potential due to good blood supply.
• Lower Success in the White Zone: Tears in the inner, poorly vascularized part of the meniscus (the "white zone") are less likely to heal, making these less suitable for repair.

Long-Term Outcomes

Preservation of Knee Function:

• Meniscus repair preserves the natural cartilage, which helps maintain joint stability and function over time.
• Patients who undergo repair instead of removal have a reduced risk of developing arthritis.

Return to Activities:

• Many patients can return to normal activities or sports within 4–6 months, provided they follow their rehabilitation program.

Prevention of Degeneration:

• Retaining as much of the meniscus as possible decreases the likelihood of knee osteoarthritis, especially in younger, active patients.

Factors Influencing Effectiveness

Type of Tear:

• Longitudinal or bucket-handle tears typically heal well after repair.
• Complex or radial tears may have a lower healing potential.

Patient Age:

• Younger patients (under 40) tend to have better healing outcomes due to higher biological activity and repair capacity.
• Older patients may experience slower recovery and lower success rates.

Concurrent Injuries:

• Combining meniscus repair with ACL reconstruction often leads to better outcomes, as the reconstructed ACL stabilizes the knee, promoting healing.

Adherence to Rehabilitation:

• Following a structured physical therapy plan and avoiding premature return to activities are critical for optimal healing.

Possible Complications of Surgery

• Infection
• Stiffness or loss of motion
• Nerve injury (rare)
• Blood clots

Post-Surgery Recovery

• Crutches for 4–6 weeks to limit weight-bearing on the knee.
• Physiotherapy for several months to restore knee strength and mobility.
• Gradual return to activities as recommended by Dr. Khoo.
• Full recovery expected in 6–12 months, depending on the complexity of the tear and adherence to rehabilitation.

What Does Surgery Involve for Me?

• Small incisions are made to access the meniscus.
• The torn meniscus is repaired with sutures or anchors.
• Post-operative pain management includes medication and icing.
• Physiotherapy starts soon after surgery to regain knee function and strength.
• Follow-up visits ensure the repair is healing properly and no complications arise.
