Quadriceps Tendon Tear
A quadriceps tendon tear occurs when a tendon that attaches one of the four quadriceps muscles (the rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius) to the kneecap suffers an injury. Usually, this condition affects middle-aged individuals who participate in sports, with men being 8 times more likely than women to sustain this type of injury.
