Sports injuries of the knee
What's going on
A knee sports injury is a condition in which the knee joint is damaged due to excessive movement or incorrect posture. This injury can involve a variety of structures in the knee joint, including anterior and posterior cruciate ligaments, medial and lateral collateral ligaments, meniscus, etc.
Causes of sports injuries in the knee joint
Poor exercise patterns: Wearing inappropriate shoes, using sports equipment inappropriately, not warming up adequately before exercising, and exercising on slippery surfaces can increase the risk of knee injuries.
Long-term weight-bearing of the knee: Long-term weight-bearing squats or a large body weight base may put excessive pressure on the meniscus of the knee joint, which can lead to injury.
Sudden change in speed of movement: Sudden deceleration or cessation during exercise can cause torsional injury to the knee joint due to rotational forces.
