Abstract
Background
An intramedullary guide is an instrument that surgeons use to align the distal femoral cut. The opening may become a channel that drains intramedullary blood to the knee joint after surgery if left open during surgery. The authors aimed to evaluate the effects of an intramedullary bone plug with respect to postoperative blood loss from a meta-analysis.
Methods
The authors performed a systematic review and meta-analysis to compare a sealed opening using an intramedullary bone plug with no bone plug. PubMed, Ovid, Embase, and Cochrane Library were used to identify all publications before May 2018. All of the included studies were evaluated for bias and heterogeneity.
Results
Six hundred and thirty-six patients from four randomized controlled trials were included in this meta-analysis. The pooled results demonstrated that patients with intramedullary plug had lower rates of blood transfusion and lower level of reduced postoperative hemoglobin than patients in whom the intramedullary canal was not plugged.
Discussion
This meta-analysis demonstrated the benefit of intramedullary sealing with a bone plug in total knee arthroplasty with respect to decreased postoperative blood loss.
