Patient-Specific Cutting Blocks

摘要

The numbers and costs of revision total knee arthroplasties are increasing and are projected to represent a significant burden to the health care system (Fig. I).1 Moreover, the epidemiology of the revisions being performed is troublesome. A significant proportion of revisions are performed within the first 5 years of the index primary arthroplasty, and an estimated 70% of revisions performed within the first 2 years of the index arthroplasty are related to surgical technique.2 There is, therefore, a compelling need to assure that primary TKA procedures performed by orthopedic surgeons of all ranges of experience are carried out accurately and reproducibly.
