The ligaments in the knee joint are quite complex, often resulting from trauma, strain injuries, or lateral impacts. Symptoms such as reluctance to move the knee, pain, and worsened pain after movement usually necessitate a hospital examination. Lateral stress tests examine the medial and lateral collateral ligaments, drawer tests check the anterior and posterior cruciate ligaments, and pivot shift tests or squat walking tests assess the meniscus. If necessary, an MRI is performed for diagnosis. Early detection and treatment are crucial. If trauma is frequent, or instability after injury occurs, one should seek hospital examination. Ligament damage often heals slowly, typically taking around a month to fully recover.
