Patellar fractures: contemporary approach to operative treatment, using different types of the tension band principles

Summary Patellar fractures are relatively common accounting to approximately 1% of all skeletal injuries. The subcutaneous anterior location of the patella makes it prone to injury, and fractures may occur as a result of direct or indirect trauma. Traffic accidents and falls are the most common causes. Patellar fractures are a diverse group of injuries, and fracture types vary considerably. The method of treatment is chosen on the basis of patients factors {age, bone quality, activity level and compliance} and fracture type. The surgical goals are anatomic reduction of the articular surface and stable fixation. Contemporary methods of treatment include screws, the tension band and a combination of the two. Frequently these injuries associated with concomitants injuries as fracture of the femur, subtrochanteric fracture, traumatic dislocation of the hip and lesions of the knee ligaments.
