Patient-specific computed tomography based instrumentation in total knee arthroplasty: a prospective randomized controlled study.

摘要

Our study did not reveal superiority of the CT-based PSI system over conventional instrumentation. Further high-quality investigations of patient-specific systems are absolutely indispensable to assess their utility for TKA. In our opinion, the surgeon applying PSI technology is required to have advanced knowledge and considerable experience with the conventional method.
