What does torn ligament mean?

A torn ligament is a complete or partial tear of a ligament, a band of tissue that connects bones together. Ligaments provide stability to joints and help to resist excessive movement. A torn ligament can be caused by a sudden forceful event, such as a sports injury, or it can occur over time due to wear and tear. Torn ligaments can cause pain, swelling, bruising, and instability in the affected joint. Treatment for a torn ligament may include rest, ice, compression, elevation, medication, and physiotherapy. In some cases, surgery may be necessary to repair a torn ligament.
