Anatomy of the Knee Joint
The knee is one of the most complex and largest joints in the body and is very susceptible to injury. The meniscus is a small, C-shaped piece of cartilage in the knee. Each knee has two menisci, the medial meniscus on the inner aspect of the knee and the lateral meniscus on the outer aspect of the knee. The medial and lateral menisci act as a cushion between the thighbone (femur) and shinbone (tibia).
Meniscal tears are among the commonest injuries to the knee joint. It can occur at any age but are more common in athletes involved in contact sports. The meniscus has no direct blood supply and for that reason, when there is an injury to the meniscus, healing is difficult.
Causes of Meniscal Injuries
Meniscal tears often occur during sports. These tears are usually caused by twisting motion or over-flexing of the knee joint. Sports such as football, tennis, and basketball involve a high risk of developing meniscal tears. They often occur along with injuries to the anterior cruciate ligament, a ligament that crosses from the femur (thighbone) to the tibia (shinbone).
Symptoms of Meniscal Injuries
Meniscal tears can be characterized into longitudinal, bucket handle, flap, parrot -beak and mixed or complex tears.
The symptoms of a meniscal tear include:
- Knee pain when walking
- A popping or clicking that may be felt at the time of injury
- Tenderness when pressing on the meniscus
- Swelling of the knee
- Limited motion of the knee joint
- Joint locking, if the torn cartilage gets caught between the femur and tibia, preventing straightening of the knee.
Diagnosis of Meniscal Injuries
A thorough medical history and a physical examination can help diagnose meniscal injuries.
In addition, Mr Ghosh may order imaging tests such as X-ray and MRI to help confirm the diagnosis.
Treatment of Meniscal Injuries
The treatment depends on the pattern and location of the tear. If the meniscal tear is not severe, Mr Ghosh may begin with non-surgical treatments that may include:
- Rest: Avoid activities that may cause injury. You may need to temporarily use crutches to limit weight-bearing.
- Ice: Ice application to reduce swelling
- Pain medications: Non-steroidal anti-inflammatory drugs (NSAIDs) to help reduce swelling and pain
- Physical therapy: Physical therapy for muscle and joint strengthening
If the symptoms persist and conservative treatment fails, you may need surgery to repair or remove the torn meniscus.
