摘要

新的TKA旨在优化患者的治疗效果,提高植入物的使用寿命,如Attune TKA。对于胫骨假体-骨水泥界面早期脱粘的潜在高速率的担忧已经被提出。我们的研究旨在前瞻性地评估连续一系列接受Attune TKA或另一种现代TKA治疗OA的患者的临床结果和x线片,以确定失败率并比较放射学异常由我们当地中心三名外科医生进行的tune TKA与2015年至2017年期间进行的96例对照TKA (PFC/Vanguard)相匹配。术后第一天、一年和两年的x线片由两位独立的盲法评估者进行分析。使用牛津膝关节评分评估临床结果并记录植入物的存活时间。手术后两年内与患者联系,由相同的独立评估人员对93例tune患者和92例对照tka患者进行临床和放射学评估。两组均未修改TKA。两组均未见骨水泥-骨或种植体-骨水泥界面处明显的辐射率(≥2mm)。两组间两个界面的辐射率(2mm)发生率相似,不影响临床结果。两组随访两年的放射率、进展和程度与随访一年相比无显著差异。在这项前瞻性队列研究中,没有发现临床相关的不良影像学特征,将连续的一系列Attune TKA与匹配的一组已建立的现代TKA设计进行比较。

Attune total knee arthroplasty: is there evidence of early tibial component de-bonding? A prospective cohort study with a minimum two year follow-up

New TKA are designed to optimize patient outcomes and improve implant longevity such as the Attune TKA. Concerns have been raised regarding a potentially high rate of early de-bonding at the implant–cement interface of the tibial component. Our study aimed to prospectively assess the clinical outcomes and radiographs of a consecutive series of patients undergoing either Attune TKA or another modern TKA for OA to establish failure rates and compare radiological abnormalities.

96 Attune TKA performed by three surgeons at our local center were matched to 96 control TKA (PFC/Vanguard) performed between 2015 and 2017. Day one, one year and two year post surgery radiographs were analyzed by two independent, blinded assessors. Clinical outcome was assessed using the Oxford Knee Score and survival of the implant recorded. Patients were contacted two years from surgery, 93 Attune and 92 control TKAs attended for clinical and radiological assessment by the same independent assessors.

No TKA in either group were revised. No significant radiolucencies (≥2 mm) at the cement-bone or implant-cement interfaces were encountered in either group. The incidence of radiolucencies (<2 mm) across both interfaces was similar between both groups and did not affect clinical outcome. There was no significant difference between the incidence, progression and extent of radiolucencies at two years follow-up in either of the groups as compared with one year. No clinically relevant adverse radiographic features were found in this prospective cohort study comparing a consecutive series of Attune TKA with a matched group of established, modern TKA designs.

期刊介绍: Journal of Arthroscopy and Joint Surgery (JAJS) is committed to bring forth scientific manuscripts in the form of original research articles, current concept reviews, meta-analyses, case reports and letters to the editor. The focus of the Journal is to present wide-ranging, multi-disciplinary perspectives on the problems of the joints that are amenable with Arthroscopy and Arthroplasty. Though Arthroscopy and Arthroplasty entail surgical procedures, the Journal shall not restrict itself to these purely surgical procedures and will also encompass pharmacological, rehabilitative and physical measures that can prevent or postpone the execution of a surgical procedure. The Journal will also publish scientific research related to tissues other than joints that would ultimately have an effect on the joint function.
