BACKGROUND Bilateral one-stage total knee arthroplasty(BTKA)is now in greater use as an alternative option for patients with bilateral end-stage knee arthropathy.However,postoperative pain and disablement during convalescence from BTKA,and procedure-related complications have been concerning issues for patients and surgeons.Although some studies reported that BTKA in selected patients is as safe as the staged procedure,well-defined guidelines for patient screening,and perioperative care and monitoring to avoid procedure-related complications are still controversial.AIM To compare the perioperative outcomes including perioperative blood loss(PBL),cardiac biomarkers,pain intensity,functional recovery,and complications between unilateral total knee arthroplasty(UTKA)and BTKA performed with a similar perioperative protocol.METHODS We conducted a retrospective study on consecutive patients undergoing UTKA and BTKA that had been performed by a single surgeon with identical perioperative protocols.The exclusion criteria of this study included patients with an American Society of Anesthesiologists score>3,and known cardiopulmonary comorbidity or high-sensitivity Troponin-T(hs-TnT)>14 ng/L.Outcome measures included visual analogue scale(VAS)score of postoperative pain,morphine consumption,range of knee motion,straight leg raise(SLR),length of stay(LOS),and serum hemoglobin(Hb)and hs-TnT monitored during hospitalization.RESULTS Of 210 UTKA and 137 BTKA patients,those in the BTKA group were younger and more predominately female.The PBL of the UTKA vs BTKA group was 646.45±272.26 mL vs 1012.40±391.95 mL(P<0.01),and blood transfusion rates were 10.48%and 40.88%(P<0.01),respectively.Preoperative Hb and body mass index were predictive factors for blood transfusion in BTKA,whereas preoperative Hb was only a determinant in UTKA patients.The BTKA group had significantly higher VAS scores than the UTKA group at 48,72,and 96 h after surgery,and also had a significantly lower degree of SLR at 72 h.The BTKA group also had a significantly longer LOS than the UTKA group.Of the patients who had undergone the procedure,5.71%of the UTKA patients and 12.41%of the BTKA patients(P=0.04)had hs-TnT>14 ng/L during the first 72 h postoperatively.However,there was no difference in other outcome measures and complications.CONCLUSION Following similar perioperative management,the blood transfusion rate in BTKA is 4-fold that required in UTKA.Also,BTKA is associated with higher pain intensity at 48 h postoperatively and prolonged LOS when compared to the UTKA.Hence,BTKA patients may require more extensive perioperative management for blood loss and pain,even if having no higher risk of complications than UTKA. 展开更多
