Which of the following characterizes a torn tendon?

A torn tendon is characterized by a partial or complete rupture of the tendon fibers. When a tendon is torn, it signifies that the structural integrity of the tendon has been compromised, either partially, where some fibers remain intact, or completely, where the tendon has entirely separated. This distinction is essential because it impacts treatment options and recovery prognosis.

In contrast, a mild sprain refers to the overstretching or slight tearing of ligaments, not tendons. An inflammatory response, while it may occur following a tendon injury, is not a defining characteristic of a torn tendon itself; inflammation is the body's reaction to any form of injury. Cartilage degradation pertains to the breakdown of cartilage tissue, which is a separate issue not directly related to tendon tears. Understanding these distinctions helps to clarify the specific nature of tendon injuries and their implications for treatment and rehabilitation.
