Application of Iced Normal Saline Combined with Cocktail Perfusion in Total Knee Arthroplasty:Randomized Controlled Trialrandomized Controlled Trial

Abstract Background: The present study was designed to investigate the safety and effectiveness of iced normal saline combined with cocktail perfusion during total knee arthroplasty (TKA).Method: Sixty patients undergoing TKA were divided into three groups, then three different intro-operative articular cavity perfusion treatment was given according to the randomized, double-blind and controlled rule. One way ANOVA analysis on visual analogue scale (VAS) score, functional recovery, drainage, and edema of the affected limb were performed to assess the efficiency of the treatment in the following three days after the operation.Results: Postoperative drainage in group A and B reduced significantly (P<0.05). The IHC scores of the surgical limbs were markedly lower comparing with the control group (P<0.05). No differential postoperative edema was observed and the patient acquired better rehabilitation in group A and B than control group. Compared with group A, no differential postoperative drainage and edema was seen in group B (P>0.05). The VAS score of group B was significantly lower than in group A(P<0.05). Postoperative recovery of the surgical limb function in group B was better than in group A (P<0.05), and PGE2 in the postoperative drainage volume of group B was significantly decreased (P<0.05).Conclusions: Intra-operation articular cavity perfusion therapy with iced normal saline combined with cocktail perfusion therapy can greatly reduce the early inflammation, contributing to the better rehabilitation of TKA.
