Patient specific instrumentation influences hemoglobin decrease after total knee replacement.

5 pagesPublished: June 13, 2017

Abstract

Patient Specific Instrumentation (PSI) may contribute to reduce blood loss after total knee replacement (TKR) by avoiding violation of the medullary canal. The purpose of the study was to compare the hemoglobin (Hb) decrease in two groups of patients undergoing TKR with PSI and conventional instrumentation.
Pre- and post-operative blood samples were collected for twenty-two patients randomly assigned to receive a PSI-assisted or conventional TKR. Post- to preoperative Hb difference was calculated.
A significant difference in Hb reduction in favor of the PSI group was registered on the last day of stay but not on the previous post-operative days: these promising results suggest a beneficial effect of PSI in blood loss reduction. PSI may hence be considered among the strategies available to control and reduce blood loss related to TKR.
