目的:本研究的目的是报告在多个机构进行机器人辅助全膝关节置换术(RA-TKA)后的患者和临床结果,并进行至少两年的随访。
方法:这是一项2016年10月至2021年6月的多中心注册研究,包括861名原发性RA-TKA患者,他们完成了至少一份患者报告的术前和术后结果测量(PROM)问卷。包括被遗忘的联合评分(FJS),关节置换的膝关节损伤和骨关节炎结果评分(KOOSJR),疼痛100分。平均年龄为67岁(35至86岁),452人是男性(53%),平均BMI为31.5kg/m2(19至58),553(64%)骨水泥和308(36%)非骨水泥植入物。
结果:术前之间随着时间的推移,PROM有显著改善,一到两年,和>两年的随访,平均FJS为17.5(SD18.2),70.2(标准差27.8),和76.7(SD25.8;p<0.001);平均KOOSJR为51.6(SD11.5),85.1(标准差13.8),和87.9(SD13.0;p<0.001);平均疼痛评分为65.7(SD20.4),13.0(标准差19.1),和11.3(SD19.9;p<0.001),分别。有8例浅表感染(0.9%)和4例修订(0.5%)。
结论:RA-TKA在多个机构中表现出一致的临床结果,具有出色的PROM,并且随着时间的推移持续改善。具有在日冕中实现目标对准的能力,轴向,和矢状面,并提供术中实时数据以获得平衡的间隙,RA-TKA在该患者群体中表现出优异的临床结果和PROM。引用这篇文章:BoneJtOpen2022;3(7):589-595。
OBJECTIVE: The aim of this
study was to report patient and clinical outcomes following robotic-assisted total knee arthroplasty (RA-TKA) at multiple institutions with a minimum two-year follow-up.
METHODS: This was a multicentre registry
study from October 2016 to June 2021 that included 861 primary RA-TKA patients who completed at least one pre- and postoperative patient-reported outcome measure (PROM) questionnaire, including Forgotten Joint Score (FJS), Knee Injury and Osteoarthritis Outcomes Score for Joint Replacement (KOOS JR), and pain out of 100 points. The mean age was 67 years (35 to 86), 452 were male (53%), mean BMI was 31.5 kg/m2 (19 to 58), and 553 (64%) cemented and 308 (36%) cementless implants.
RESULTS: There were significant improvements in PROMs over time between preoperative, one- to two-year, and > two-year follow-up, with a mean FJS of 17.5 (SD 18.2), 70.2 (SD 27.8), and 76.7 (SD 25.8; p < 0.001); mean KOOS JR of 51.6 (SD 11.5), 85.1 (SD 13.8), and 87.9 (SD 13.0; p < 0.001); and mean pain scores of 65.7 (SD 20.4), 13.0 (SD 19.1), and 11.3 (SD 19.9; p < 0.001), respectively. There were eight superficial infections (0.9%) and four revisions (0.5%).
CONCLUSIONS: RA-TKA demonstrated consistent clinical results across multiple institutions with excellent PROMs that continued to improve over time. With the ability to achieve target alignment in the coronal, axial, and sagittal planes and provide intraoperative real-time data to obtain balanced gaps, RA-TKA demonstrated excellent clinical outcomes and PROMs in this patient population.Cite this article: Bone Jt Open 2022;3(7):589-595.
