Purpose: To assess blood loss and transfusion between Navigation assisted minimally invasive total knee arthroplasty (TKA) performed with immediate release of drain and 1-hour - delayed release of drain.
Materials and Method : We carried out a prospective randomised study to evaluate the blood loss in 100 knees having a Navigation-assisted minimally invasive TKA by dividing into two groups, one having a immediate release of drain (group A) and the other having a 1 hour-delayed release of drain(group B). All patients had a unilateral primary TKA using cemented type.
Results : The mean drainage of blood was 464.9 ml in a immediate release of drain group and 409.1ml in 1 hour-delayed release of drain group. This difference was not statistically significant (p=0.117). The pre- and postoperative hemoglobin were mean 13.36g/dl and 10.77 g/dl in group A, mean 12.8 g/dl and 10.37 g/dl in group B. All patients were not transfused in intra- and post operation.
Conclusion : There was no significant difference in total blood loss of drain and pre- and postoperative hemoglobin between the two groups by the Navigation-assisted minimally invasive TKA. All patients were not transfused in intra- and post operation.
