The goal of this meta-analysis was to compare PSI with conventional instrumentation (CI) in patients undergoing TKA. Methods: A literature search was performed in PubMed, Embase, Springer, Ovid, China National Knowledge Infrastructure, and the Cochrane Library. A total of 10 randomized controlled studies involving 837 knees comparing outcomes of PSI TKAs with CI TKAs were included in the present analysis. Outcomes of interest included component alignment, surgical time, blood loss, and hospital stay. Results: The results presented no significant differences between the two instrumentations in terms of restoring a neutral mechanical axis and femoral component placement. However, their differences have been noted regarding the alignment of the tibial component in coronal and sagittal planes. Also, 3min less surgical time was used in PSI patients. Conclusions: Based on these findings, PSI appeared not to be superior to CI in terms of the post-operative mechanical axis of the limb or femoral component placement. Despite a statistical difference for operative duration, the benefit of a small reduction in surgical time with PSI is clinically irrelevant. Level of evidence: Therapeutic study (systematic review and meta-analysis), Level I.
