Cartilage is a tough, flexible tissue found throughout the body. It covers the surface of joints, acting as a shock absorber and allowing bones to slide over one another.
It can become damaged as a result of:
Symptoms of cartilage damage
Symptoms of cartilage damage in a joint include:
- joint pain – this may continue even when resting and worsen when you put weight on the joint
- swelling – this may not develop for a few hours or days
- a clicking or grinding sensation
- the joint locking, catching, or giving way
It can sometimes be difficult to tell a cartilage injury apart from other common joint injuries, such as sprains, as the symptoms are similar.
When to get medical advice
If you've injured your joint, it's a good idea to try self-care measures first. Sprains and minor cartilage damage may get better on their own within a few days or weeks.
More severe cartilage damage probably won't improve on its own. If left untreated, it can eventually wear down the joint.
- you can't move the joint properly
- you can't control the pain with ordinary painkillers
- you can't put any weight on the injured limb or it gives way when you try to use it
- the injured area looks crooked or has unusual lumps or bumps (other than swelling)
- you have numbness, discolouration, or coldness in any part of the injured area
- your symptoms haven't started to improve within a few days of self-treatment
Treatments for cartilage damage
Self-care measures are usually recommended as the first treatment for minor joint injuries.
For the first few days:
- protect the affected area from further injury by using a support, such as a knee brace
- rest the affected joint
- elevate the affected limb and apply an ice pack to the joint regularly
- take ordinary painkillers, such as paracetamol or non-steroidal anti-inflammatory drugs (NSAIDs) You shouldn’t take ibuprofen for 48 hours after your injury as it may slow down healing.
Get medical advice if your symptoms are severe or don't improve after a few days. You may need professional treatment, such as physiotherapy, or possibly surgery. The health professional treating you will discuss with you the best treatment option for you.
