Meniscus Repair vs Meniscectomy

Should you repair or remove a torn meniscus? Compare recovery, long-term joint health, and candidacy.

Meniscus Repair (Sutures)

Meniscus repair stitches the torn meniscus back together using arthroscopic sutures. The goal is to preserve the meniscus and its shock-absorbing function. Best for: Tears in the outer third (red zone, good blood supply), vertical/longitudinal tears, younger patients, tears concurrent with ACL reconstruction. Recovery: 3-6 months, restricted weight-bearing for 4-6 weeks, brace required, limited squatting/kneeling for 4-6 months.

Meniscectomy (Partial Removal)

Partial meniscectomy trims away the damaged portion of the meniscus, leaving as much healthy tissue as possible. This is the most common meniscus surgery. Best for: Complex tears, tears in the inner third (white zone, poor blood supply), degenerative tears in older patients, flap tears. Recovery: 3-6 weeks, weight bearing immediately, most patients return to normal activities in 4-6 weeks.

Why Repair Matters for Long-Term Health

The meniscus absorbs 50-70% of the load across your spine. Removing meniscus tissue increases stress on cartilage and accelerates arthritis. Studies show patients who undergo meniscectomy have a 5-10x higher risk of knee arthritis within 15-20 years compared to those who have a successful repair. For younger patients especially, surgeons strongly prefer repair when the tear pattern allows it.

Frequently Asked Questions

Can all meniscus tears be repaired?
No. Only about 20-30% of meniscus tears are repairable. Tears in the outer third with good blood supply are best candidates. Complex, degenerative, or inner-zone tears typically require partial meniscectomy.
What happens if a meniscus repair fails?
If a repair fails (10-20% chance), it is usually converted to a partial meniscectomy. This is a shorter recovery but means losing the meniscus tissue.
Can you play sports after meniscectomy?
Yes. Most athletes return to sports 6-8 weeks after partial meniscectomy. However, long-term high-impact activity on a meniscus-deficient knee may accelerate wear on the joint.
How do I know if my tear is repairable?
Your surgeon determines repairability based on MRI and arthroscopic visualization. Tear location (red zone vs white zone), tear pattern, tissue quality, and timing all factor into the decision.
