About meniscal tears
The knee joint is cushioned by thick pads of rubbery cartilage called menisci. The meniscal cartilage can be torn in a number of ways such as a sharp twisting movement or a direct blow to the knee.
Meniscal tears can happen when playing sports that require sudden changes of direction, such as football, squash or skiing.
Your knee cartilage can also be damaged as a result of bone conditions such as arthritis.
Most meniscal tears that cause symptoms don’t heal by themselves and will need some form of treatment.
You’ll usually need to go to A&E with this kind of injury, and will likely be referred to an orthopaedic surgeon for diagnosis and a treatment plan.
What is meniscal cartilage?
Meniscal cartilage provides cushioning and reduces friction in the joint. If the cartilage is torn, the jagged edges affects smooth movement in the joint, causing inflammation and trapped tissue.
Damaged cartilage can also lead to bone damage and arthritis as the knee bones catch against each other.
Symptoms of MCL injury
When the meniscus tears, you have the following symptoms:
- pain in your knee – some people only have mild pain, and for others, the pain may come and go
- swelling, usually several hours after the injury
- feeling as though your knee is catching or locking, usually when your knee is bent
- your knee feeling ‘loose’, as though it’s going to give way
- being unable to bend and extend your knee fully
- your knee may feel tender along the line of the joint
Treatment of a meniscus tear
The treatment you’re offered will depend on where the tear is, how big it is, how severe your injury is and your age.
Initially, you can control your pain and swelling by resting, icing and elevating your knee. You can mange pain and swelling with over the counter anti-inflammatory medicines.
If you have a minor tear in your cartilage, it is possible to strengthen the muscles around your knee to compensate for the damage and reduce the symptoms. Our team of physiotherapists may give you a programme of exercises to help your knee recover.
Your consultant may recommend surgery for your torn meniscus if the symptoms have not improved with physiotherapy. Surgery may involve resection of the torn fragment or repair of the tear.
Meniscal repair is usually carried out through keyhole surgery (arthroscopy), using a small video camera and monitor and small surgical instruments.
Your surgeon might stitch the tear together, or smooth the jagged piece of cartilage by trimming or shaving the edges.
