What are the structures inside the knee?
How does the meniscus get injured?
Usually this is caused by a twisting type injury. Sometimes it results from a more complex injury where other structures are damaged.
How can you tell if I have sustained a tear?
The mechanism of injury may suggest a tear. You may experience sharp pain on either side of the knee, feel clicking or catching and sometimes the knee can lock. Clinical examination may reproduce this, but in some cases a MRI scan is needed to confirm the diagnosis.
How is it treated?
When your symptoms fail to settle with other measures (e.g. physiotherapy) then key-hole surgery (arthroscopy) is performed. At surgery the meniscus is examined and where a tear is found, it will be treated by either trimming the torn portion or by suture repair.
Can all tears be repaired?
The meniscus has poor healing qualities and so therefore only tears close to the blood supply can be repaired.
How is a tear repaired?
Through the keyhole incisions made in your knee, very fine sutures are passed across the tear and a knot tied.
