Can a torn meniscus heal on its own?
Some meniscus tears can heal without surgery — small tears in the outer third of the meniscus, the "red zone" that has blood supply. Tears in the inner two-thirds can't truly heal because no blood reaches them — but "won't heal" doesn't automatically mean "needs surgery": many stable tears become painless with rehab even though the tear remains.
The decision tree, honestly
- Mechanical symptoms — locking, catching, a knee that won't straighten? A displaced fragment is involved; these usually need arthroscopic surgery.
- Pain without locking? Six weeks of proper rehab is the evidence-backed first move — a large share of these knees quiet down and stay quiet.
- Young athlete with a repairable tear? Repair over removal, almost always. Saving meniscus is saving the knee's shock absorber — the arthritis math decades out depends on it.
Repair vs. removal — the recovery trade nobody explains
A meniscectomy (trimming the torn piece) recovers in weeks; a repair (stitching it) takes months protected — and is still the better long-game call when the tear is repairable, especially under 40. If a surgeon quotes you one recovery time without explaining which operation, ask which one. It's the whole ballgame.
