What is indicated by a Grade III sprain?

A Grade III sprain indicates a complete tear of the ligament involved. In sports medicine, sprains are classified into three grades based on the severity of the injury. A Grade I sprain involves minor stretching of the ligament with minimal effect on its integrity, while a Grade II sprain indicates a partial tear, causing some instability in the joint. In the case of a Grade III sprain, the ligament is entirely torn, leading to significant instability in the joint and potentially requiring surgical intervention for proper healing. This complete rupture means that the joint may not function properly without the support of the ligament, making it essential to seek appropriate medical treatment.
