Mild meniscus injuries have the potential to heal on their own, usually within 1-3 months. However, severe meniscal injuries require surgery to heal. The meniscus is a half-moon shaped cartilage structure in the knee joint that supports knee movement. The meniscus becomes progressively more damaged by trauma and chronic strain, causing knee pain, popping after activity, etc. Severe meniscal injuries can lead to knee strangulation. Mild meniscus injury can be gradually recovered within 1-3 months through conservative treatment, avoiding strenuous sports such as running and jumping during the recovery period. Oral medications such as glucosamine, aminochondroitin sulfate, and ibuprofen can promote inflammation and pain relief and meniscus repair. Severe meniscus injuries require surgery. Different types and severity of meniscus injury require different treatment methods. Patients should go to the hospital for magnetic resonance examination to make a clear diagnosis and then undergo regular treatment.
