ABSTRACT
Objective To evaluate the effect of fast-track TKA upon the recovery time and degree of satisfaction of the patients.Methods 208 patients with primary osteoarthritis between 2013 and March 2015 were randomly divided into 2 groups.In fast-track TKA group was established in peri-operative analgesia,blood management,postoperative anticoagulation,surgical skill and mitigation of perioperative stress.In TKA group,conventional surgical management mode was followed.Identical discharge standards were established for patients in 2 groups to evaluate the recovery time.The patients' degree of satisfaction at postoperative 2 weeks was assessed by numerical rating scale (NRS).The degree of satisfaction about acquisition of preoperative information,degree of satisfaction about postoperative analgesia and postoperative function were statistically compared between 2 groups.Postoperative complication,blood transfusion rate,infectious events within postoperative 3 months,thrombosis-related events,re-operation and death were recorded.Results In fast-track TKA group,the mean discharge time was (2.3±1.2) d,significantly shorter compared with (4.7±5.1) d in TKA group.The mean NRS score in fast-track TKA group was 9.8±0.5 and 9.1±1.4 in TKA group.In fast-track TKA group,the mean scores of the degree of satisfaction about acquisition of preoperative information,degree of satisfaction about postoperative analgesia and postoperative function were 27.7±7.3,9.8± 1.7 and 9.6± 1.3,significantly higher than 15.5±10.1,9.2±2.2 and 8.7±1.8 in the TKA group.In fast-track TKA group,postoperative blood transfusion rate was 3.9％,considerably lower than 11.4％ in TKA group.Conclusion Fast-track TKA can shorten the length of hospital stay,not increase the mortality rate and postoperative complication,accelerate the recovery of daily activity and effectively enhance the degree of satisfaction of the patients.
