Meniscus tear (knee cartilage damage)
A meniscus tear is a common type of damage to cartilage in the knee. The cartilage is found between the bones in the knee joint and protects them when you move. It usually gets damaged because of an injury.
Check if you have a meniscus tear
A meniscus tear usually happens when you twist your knee while playing sport. But it can also happen from more minor injuries such as twisting when standing up.
Symptoms of a meniscus tear include:
- knee pain or tenderness
- stiffness or swelling around your knee – the swelling may not start for a few hours or days
- difficulty bending, straightening or moving your knee
- your knee giving way when you try to stand
- a crunching or clicking feeling when you move your knee
The symptoms can be similar to sprains.
How to ease symptoms of a meniscus tear
There are some things you can do to ease symptoms of a meniscus tear.
stop any exercise or activities and rest your knee when you can during the first few days
put an ice pack (or bag of frozen peas) wrapped in a towel on your knee for up to 20 minutes every 2 to 3 hours
wrap a bandage around your knee or wear a knee support – remove it when you sleep
keep your leg raised on a pillow as much as possible
take paracetamol to ease pain
do not use heat packs and avoid hot baths
do not drink alcohol
do not massage your knee
do not carry anything heavy
do not completely stop moving your knee – after a few days of resting, try to do some gentle movements
A pharmacist can help with a meniscus tear
You can ask a pharmacist about painkillers and the types of knee supports you can get.

Treatments for a meniscus tear
A meniscus tear can get better on its own without treatment, but it can take a while to heal.
Sometimes, physiotherapy may be recommended to help reduce pain and improve movement and strength in the knee.
If the damage is severe, you may need arthroscopy surgery to repair or remove the damaged cartilage.
