What it is
Each knee has two menisci that cushion and stabilize the joint. Tears can come from a twisting injury or from gradual wear (“degenerative” tears). Reports often describe the location and pattern of the tear.
How common is it?
Common, both from sports injuries and from age-related wear. Degenerative meniscus tears are frequently seen on MRIs of people with little or no knee pain.
What's usually next
Many tears improve with time, activity changes, and physical therapy. Surgery is considered mainly for specific tears, locking, or symptoms that do not settle — guided by how the knee actually feels and functions.
When it usually isn't — and when it might be — worrying
Usually reassuring
- Described as “degenerative” or age-related
- No knee locking or giving way
- Symptoms improving with rest and therapy
Worth discussing with your doctor
- Knee that locks, catches, or gives way
- A large or “bucket-handle” tear
- Significant swelling or instability after an injury
Questions to ask your doctor
- 1Is this an injury-related or a degenerative tear?
- 2Does it explain my symptoms?

- 4Which activities should I avoid for now?
