International Journal of Orthopedics and Rehabilitation
The aim of this study was to compare the need for blood transfusion and other outcomes when using patientspecific instrumentation (PSI) versus traditional instrumentation. 45 patients underwent TKA with either PSI (12 unilateral/9 bilateral) or traditional instrumentation (19 unilateral/5 bilateral) using the same final implants.
