A torn meniscus is one of the most common knee injuries, in athletes and in adults over 40. The good news: not every tear needs surgery. Here’s how Dr. Zarur decides.
What is the meniscus?
Each knee has two menisci, C-shaped cushions that absorb impact and help keep the joint stable. When they tear, the knee can hurt, swell or catch.
Common symptoms
- Pain on the inside or outside of the knee
- Swelling during the first days
- A knee that catches, locks or won’t fully straighten
When rehab is enough
Small, stable tears, and many tears related to age, often improve with physical therapy, activity changes and time.
When surgery makes sense
Surgery is usually recommended when the knee locks, when the tear is large or unstable, or when it happens together with an ACL injury. Whenever possible, Dr. Zarur repairs the meniscus instead of removing it, to protect the knee in the long term.
The bottom line
An accurate diagnosis, with an exam and often an MRI, is what decides the treatment. If your knee keeps catching or swelling, it’s time to get it checked.
