Metal Fatigue Fracture After Revision Total Knee Arthroplasty: A Retrieval Analysis
decreased (p < 0.0001) after 20 min of sputter time. Fatigue cracks propagated through equiaxed Ti-6Al-4V and wrought CoCrMo grains. These data support a hypothesized mechanism where insufficient implant fixation with bone or cement promotes localized damage accumulation within the modular junction, fatigue crack initiation and subsequent fracture.
