Within the knee joint, the cartilage – the joint surface covering the ends of the bones – acts as a shock absorber that cushions the bones, allowing them to move smoothly. It can become damaged through arthritis or by an accident where the meniscus is torn during sports such as tennis, hockey, football or skiing.

Causes

  • Trauma or Impact: Direct blows to the knee, such as during sports or accidents, can damage the cartilage, leading to tears or wear.
  • Overuse or Repetitive Motion: High-impact activities or repeated stress on the knee, like running or jumping, can gradually wear down the cartilage.
  • Sudden Twisting Movements: Abrupt changes in direction or twisting of the knee, common in sports like basketball or soccer, can cause cartilage tears.
  • Ageing and Degeneration: As we age, the cartilage in the knee naturally wears down, making it more susceptible to injury and degeneration.
  • Underlying Conditions: Conditions like osteoarthritis can weaken knee cartilage, increasing the likelihood of injury even with minor stress or impact.
