Ruptures Of The Quadriceps And Patellar Tendons Of The Extensor Mechanism: A Review, Judd R. Fitzgerald
Ruptures Of The Quadriceps And Patellar Tendons Of The Extensor Mechanism: A Review, Judd R. Fitzgerald
UNM Orthopaedic Research Journal
Damage to the quadriceps and patellar tendons of the extensor mechanism can be devastating and often life-changing injuries that require prompt diagnosis and treatment. A sound understanding of anatomy, biomechanics, and degenerative changes of both tendons and the extensor mechanism of the knee can help guide surgical repair and postoperative rehabilitation of patients. Immediate primary repair has often resulted in improved postoperative results compared with delayed reconstruction, and the avoidance of gap formation by use of careful techniques and augmentation has been critical for successful treatment. Additionally, patients with extensor mechanism injuries frequently have medical comorbidities or notable tendon degeneration; …

Background: Stainless steel wires are commonly used to close the sternum after cardiac-related operative procedures. However, complications have been reported associated with fracture of wires and subsequent migration into the chest cavity. The objective of this study was to biomechanically evaluate the role of surgeons in contributing to wire failure. We hypothesized that surgeons may impose damage to the sternal wire, which may be exacerbated by postoperative wire degradation and patient movement.
Methods: A biomimetic sternal model and custom test fixture simulated a median sternotomy. The sternum was closed by a fellowship-trained cardiothoracic surgeon using figure-of-eight and simple closure techniques. …
