What is a Pellegrini-Stieda Lesion?
A Pellegrini-Stieda lesion is a serious injury of the knee that often follows a traumatic accident. There are multiple types of knee injuries ranging from a straightforward sprain to a fracture, a dislocation, or even a tear of the ligament. Some of the ligaments that people might tear include the anterior cruciate ligament (ACL), the meniscus, or the medial collateral ligaments (MCL). If someone sustains a tear of their MCL, this injury might be followed by the development of a Pellegrini-Stieda lesion.
