Abstract
Patella fractures can be caused by excessive tension through the extensor mechanism or a direct impact. Non-displaced fractures with an intact extensor mechanism can be treated nonoperatively. Surgical treatment is recommended for fractures that either disrupt the extensor mechanism or have greater than 2 to 3 mm of step-off and greater than 1 to 4 mm of displacement. Tension band fixation is the most commonly employed surgical technique; however, this can be technically demanding, especially in multifragmentary fractures. Symptomatic hardware is the most common complication following operative treatment. Functional impairment remains common after treatment of patella fractures. The purpose of this article is to review current treatment strategies to help optimize the management of patients with such patella fractures.
