微创DAA行全髋关节置换术对患者恢复及预后的影响

目的 探讨微创直接前侧入路（DAA）行全髋关节置换术（THA）对患者术后功能恢复及预后的影响。方法 选择2018年3月~2019年2月我院行THA患者112例，采用随机数字表法分为对照组和观察组，每组56例。对照组选取PLA，观察组选取DAA，比较两组围术期指标、Harris评分及并发症发生率。结果 观察组手术时间长于对照组[（112.34±12.81）min vs（98.56±10.13）min]，术中出血量少于对照组[（236.26±28.54）ml vs（382.64±40.17）ml]，住院时间短于对照组[（7.40±1.86）d vs（9.37±2.29）d]，Harris评分高于对照组[（88.97±3.01）分vs（81.10±2.45）分]，差异均有统计学意义（P＜0.05）。两组并发症发生率比较，差异无统计学意义（P＞0.05）。结论 微创DAA入路行THA有助于减少术中出血量、缩短住院时间，加快髋关节功能恢复，且不增加术后并发症。

Minimally Invasive DAA Approach for Total Hip Arthroplasty for Postoperative Functional Recovery and Prognosis

Objective To investigate the effect of minimally invasive direct anterior approach (DAA) total hip arthroplasty (THA) on postoperative functional recovery and prognosis. Methods From March 2018 to February 2019, 112 patients with THA were enrolled in our hospital. They were randomly divided into control group and observation group, with 56 cases in each group. PLA was selected in the control group and DAA was selected in the observation group. Perioperative index, Harris score and complication rate were compared between the two groups.Results The operation time of the observation group was longer than that of the control group [(112.34±12.81) min vs (98.56±10.13) min], the intraoperative blood loss was less than that of the control group [(236.26±28.54) ml vs (382.64±40.17) ml],the hospital stay was shorter than the control group [(7.40±1.86) d vs (9.37±2.29) d], and the Harris score was higher than the control group [(88.97±3.01) points vs (81.10±2.45) points],the difference was statistically significant(P<0.05). There was no significant difference in the incidence of complications between the two groups (P>0.05).Conclusion Minimally invasive DAA approach to THA can help reduce intraoperative blood loss, shorten hospital stay, and accelerate hip function recovery without increasing postoperative complications.
