Material and methodsRetrospective analysis of the duration of 243 interventions (skin-to-skin time and ischaemia time) performed by the same surgeon. 72 cases operated with conventional instruments (CI), 68 operated with computer assisted surgery (CAS) and 103 with personalized instrumentation system (PSI). ResultsCI skin-to-skin 87.85 min (SD 11.86). CI ischaemia 94.44 min (SD 11.49). CAS skin-to-skin 123.46 min (SD 11.27). CAS ischaemia 129.63 min (SD 11.37). PSI skin-to-skin 78.69 min (SD 13.06). PSI ischaemia 84.63 (DE 12.06). There is a significant difference between PSI and the other instrumentation systems (p 0.000). ConclusionsIn our study, the time taken for TKA was significantly lower when we used customized cutting blocks rather than other systems. ER -
