Medial Cartilage Meniscus Injury
Each knee joint has two crescent-shaped cartilage menisci. These lie on the medial (inner) and lateral (outer) edges of the upper surface of the tibia (shin) bone. They are essential components, acting as shock absorbers for the knee as well as allowing for the proper interaction and weight distribution between the tibia and the femur (thigh bone). As a result, injuries to either meniscus can lead to critical impairment of the knee itself.
What is a medial meniscus injury?
The medial meniscus is more prone to injury than the lateral meniscus as it is connected to the medial collateral ligament and the joint capsule and so is less mobile. Hence, any forces impacting from the outer surface of the knee, such as a rugby tackle, can severly damage the medial meniscus. In addition, medial meniscal injuries are often also associted with injuries to the anterior cruciate ligament. Other mechanisms of injury may be twisting of the knee or degenerative changes that are associated with age. Any of these circumstances may lead to tearing of the medial meniscus, which in serious cases may require surgical intervention.
Symptoms of medial meniscus tear
A history of trauma or twisting of the knee
Pain on the inner surface of the knee joint
Swelling of the knee within 24-48 hours of injury
Inability to bend knee fully- this may be associated with pain or a clicking noise
A positive sign (pain and/or clicking noise) during a "McMurrays test"
Pain when rotating and pressing down on the knee in prone position (video).
"Locking" of the knee
Inability to weight bear on the affected side
Types of meniscal injuries:
Degenerative Changes: This may lead to edges of the menisci becoming frayed and jagged
Longitudical Tears: This is a tear that occurs along the length of the meniscus
Bucket- Handle Tears: This is an exaggerated form of a longitudical tear where a portion of the meniscus becomes detached from the tibia forming a flap that looks like a bucket handle
Treatment of medial cartilage meniscus injury
What can the athlete do:
1. Apply RICE to the injured knee.
2. Wear a heat retainer or support.
3. Gentle exercises to maintain quadriceps strength, although care should be taken not to aggravate the symptoms.
4. Take a glucosamine / joint healing supplement.
5. Consult a Sports Injury Specialist.
