A meniscal tear is defined as a tear of the meniscus inside the knee joint. There are other types of knee cartilage that can also be injured.

You've all seen the footballer on the telly - one moment he's running full pelt, the next he's tripped over another player and is clutching his knee in agony. There's a good chance an injury to his knee cartilage is at least part of the problem. There are two types of cartilage injuries that you can get in your knee:

  • Meniscal tears
  • Articular cartilage injuries

Meniscal tears are usually caused by landing suddenly on your knee at the same time as twisting it. They are common in:

  • Rugby
  • Football
  • Tennis
  • Basketball
  • Squash
  • Ski-ing

Having said all that, you can also get a torn meniscus that just develops gradually as you get older - these are called degenerative tears.

Articular cartilage injuries can also be caused by a sports injury but don't happen on their own as often. More often you get an articular cartilage injury when you have had a particularly bad injury to the knee and damaged other parts of the knee too.

Read more about who gets meniscal tears and articular cartilage injuries and what causes them.

The common symptoms of a meniscal tear are:

  • Pain
  • Swelling
  • Stiffness

These symptoms usually come on soon after an injury but will come on more gradually if the tear is one that has developed as a result of getting older (a degenerative tear). Articular cartilage damage causes similar symptoms but articular cartilage is more often injured alongside other knee injuries, so it may be those other injuries that cause most of your symptoms.

It's hard to say exactly when you should see a doctor as it depends largely on how bad your knee is and how it is affecting you. Certainly if you have had a painful, swollen, stiff knee for more than a month or so, it would be worth getting medical advice.

If you have injured your knee and it has swelled up immediately, especially if you can't put weight on it, you should get urgent medical advice as you may have a fracture or torn a ligament. For further details see separate leaflet called Knee Ligament Injuries.

It is usually possible for a doctor to diagnose your injury once they have heard how you injured your knee and have had a chance to examine your knee. Sometimes they will arrange for you to have an MRI scan, particularly if it has been going on long enough for them to think that it won't get better with time and physiotherapy and that you might need an operation. X-rays aren't helpful in diagnosing meniscal and cartilage injuries.

Find out more about the tests used.

For the first couple of days or so, you need to take it easy so you don't injure your knee any further - putting your leg up and using ice and a compression bandage and taking painkillers if you need to.

After the initial really bad pain has begun to ease, it's important to get your knee moving. An appointment with a physiotherapist or a sports therapist at this stage can be very helpful. 

Find out more about physiotherapy.

Further treatment will then depend on how your injured knee is affecting you. If it is stopping you from being able to work, for example, you may need to see an orthopaedic surgeon and consider an operation.
