Sports Related Knee Pain and Treatment

Knee pain is the most common of all sports injuries – and not only for those athletes whose activities involve running flat out and changing direction at speed. Indeed, virtually every sport has its share of knee injuries and related problem

Cartilage Problems: What can you do to avoid, or recover from, this all-too-common injury?

Cartilage tears in the knee are ten a penny among sports people. Some of us remain blissfully untroubled by them, while others experience discomfort, pain and even disability. Happily this is one area where science is moving forward briskly.

Knee Pain: Prevention & Treatment deals with the menisci – what are more commonly known as the 'shock absorbing cartilage' in the knee joint. These two crescent-shaped pads of cartilage are present in both knees. The pad on the inner side of the knee is the 'medial meniscus', while the outer one is the 'lateral meniscus'.

Together they act in four different ways to improve knee function:

1. They spread load across the joint. In standing, this is up to 50% of the supported load; in flexion (bending at the knee) it increases to 90%

2. They improve joint congruency or stability

3. They increase the contact surface area of the main leg bones, helping to spread the weight of the body across a greater area of articular cartilage

4. They help to circulate synovial (joint) fluid around the knee.

Crucially, the menisci have limited healing potential as their blood supply only reaches the outermost 10% to 30% of each meniscus. Within this region tears may heal. But more centrally-located tears have very little chance of healing.
