Posterolateral corner and arcuate fractures can cause significant disruption to the stability and kinematics of the knee. This study aimed to determine the biomechanical performance of a novel spiked washer (SW) and intramedullary screw technique compared with a tension slide technique (TST) for the repair of arcuate fractures. Sixteen matched fresh-frozen cadaver knees underwent repair. Each specimen underwent transection of the posterolateral corner and lateral capsule along with a proximal fibula osteotomy to simulate an arcuate fracture. Eight specimens underwent repair with a SW technique and 8 underwent repair with a TST. Each specimen underwent cyclic loading followed by load to failure. Gap formation, ultimate load to failure, energy to failure, and stiffness were assessed. The SW technique had significantly less gap formation and higher load to failure. Furthermore, the SW technique had significantly higher stiffness and energy to failure. A SW and screw technique provided a significantly stronger construct with less gap formation when compared with a TST. [Orthopedics. 2024;47(5):e277–e281.] [ABSTRACT FROM AUTHOR] |
