Grade III muscle strain is characterized by which description?

Muscle strain grading relates to how completely the muscle fibers are torn and how much function remains. In a Grade III injury, the muscle is torn through to the core, breaking its continuity entirely. This causes a severe loss of strength and function, often with swelling and sometimes a palpable gap where the muscle is ruptured. That description—complete tear across the muscle fibers with loss of continuity and function—is exactly what Grade III represents. The other ideas fit less severe injuries: a partial tear with preserved continuity describes a Grade II injury, a minor tear aligns with Grade I, and a contusion with bruising is a direct blunt injury to the muscle that causes bleeding without fiber rupture.
