Sprain classification

Sprain classification assesses the severity of ligament injuries caused by overstretching or tearing. Grade 1 sprains involve mild stretching with little or no ligament damage, resulting in some pain and swelling. Grade 2 sprains are moderate, with partial tearing, more significant pain, swelling, and some joint instability. Grade 3 sprains are severe, featuring complete ligament rupture, significant pain, swelling, and often noticeable joint instability or looseness. Proper assessment helps determine appropriate treatment, ranging from rest and ice for minor sprains to immobilization or surgery for severe injuries.
