Since the early 2000s, oxidized zirconium implants have emerged as a valuable option in total hip and knee arthroplasty due to their wear resistance and suitability for patients with metal hypersensitivity. The surface of these components is created through a heating and oxidation process of a zirconium alloy, resulting in a thin layer with favorable wear properties. However, there have been few reports of severe metallosis resulting from inadvertent wear of oxidized zirconium components through various mechanisms, including dissociation of the polyethylene liner and joint instability. We present a case involving a dramatic failure of an oxidized zirconium total knee arthroplasty, necessitating a staged revision arthroplasty.
自 21 世纪初以来,氧化锆植入物因其耐磨性和对金属过敏患者的适用性,已成为全髋关节和膝关节置换术中的重要选择。这些组件的表面是通过对锆合金进行加热和氧化处理而形成的,形成的薄层具有良好的耐磨性能。然而,关于氧化锆组件因意外磨损而导致严重金属中毒的报道并不多,其机制多种多样,包括聚乙烯衬垫解离和关节不稳定。我们介绍了一例氧化锆全膝关节置换术的严重失败病例,患者不得不进行分期翻修关节置换术。

Osteolysis due to polyethylene wear is a well-known complication associated with total knee arthroplasty (TKA). Here, we present the case of one failure that has been rarely reported. We report the case of a 51-year-old male who fractured through a large osteolytic lesion in his femur after a previous TKA. The patient presented 4 years after revision TKA after a fall and was found to have fractured through the large lesion. After a diagnostic workup, he was treated with open reduction and internal fixation (ORIF) of the distal femur fracture, and the fixation was augmented with a morselized femoral head allograft and ViviGen (LifeNet Health, Virginia Beach, VA). Osteolysis secondary to polyethylene wear and reactions to arthroplasty components continues to be an ever-present complication of TKAs.
聚乙烯磨损导致的骨溶解是众所周知的全膝关节置换术(TKA)并发症。在此,我们介绍一例鲜有报道的失败病例。我们报告了一名 51 岁男性的病例,他在接受过一次 TKA 后,因股骨大面积溶骨病变而骨折。患者在翻修 TKA 4 年后因摔倒而就诊,发现骨折是通过大的病灶造成的。经过诊断检查后,他接受了股骨远端骨折切开复位内固定术(ORIF)治疗,并用骨化股骨头同种异体移植物和ViviGen(弗吉尼亚州弗吉尼亚海滩的LifeNet Health公司)增强了固定。聚乙烯磨损引起的骨溶解和对关节成形组件的反应一直是全膝关节置换术的并发症。

The use of dual-mobility systems in both primary and revision total hip arthroplasty for patients with concern for instability has become increasingly popular. While these systems are an effective means for combating instability, they are not without unique complications, such as liner malseating. We describe an intraoperative technique to evaluate for malseating via fluoroscopy, allowing a surgeon to identify and correct malseating intraoperatively. Reducing the incidence of liner malseating in dual-mobility total hip replacement systems could reduce overall complication rates postoperatively and presumably improve their efficacy.
在初次和翻修全髋关节置换术中使用双活动度系统治疗存在不稳定性问题的患者越来越受欢迎。虽然这些系统是对抗不稳定性的有效手段,但也并非没有独特的并发症,例如衬垫错位。我们介绍了一种通过透视评估内衬脱落的术中技术,使外科医生能够在术中识别并纠正内衬脱落。在双活动度全髋关节置换系统中减少衬垫错位的发生率可以降低术后的总体并发症发生率,从而提高疗效。

Background

Relationships between industry and physicians are critical for innovation in the field of arthroplasty surgery. However, these relationships can present a conflict of interest (COI) for medical research and are required to be disclosed by most journals. The rate of accurate disclosures by physicians has not been studied in arthroplasty surgery.

Methods

The names of all authors publishing in The Journal of Arthroplasty and Arthroplasty Today between 2014 and 2018 were obtained from MEDLINE. Financial disclosure statements were obtained from the journal websites and manually compared against Open Payments. Statistical comparisons were made using chi-square testing with significance defined as P < .05.

Results

From 2014-2018, 3147 articles were published with 4038 authors meeting inclusion criteria. Of authors with financial disclosures, 2298 (57%) authors correctly disclosed. The total value of disclosed COI equaled $1.71 billion. The total value of undisclosed conflicts of interest equaled $334 million. For payments >$1,000,000 physicians disclosed accurately 86% of the time. For payments between $100 and $9999 physicians accurately disclosed 26% of the time. Senior authors disclosed correctly 72% of the time, which was significantly higher compared to middle and first authors.

Conclusions

There is a high prevalence of inaccurate disclosures in the field of arthroplasty surgery. This suggests a need to further educate early-career physicians on what constitutes a COI. Standardization of disclosure forms and verifications with the Open Payments Database can help increase the rate of accurate disclosures.
背景工业界与医生之间的关系对于关节置换手术领域的创新至关重要。然而,这些关系会给医学研究带来利益冲突(COI),大多数期刊都要求披露这些关系。方法从 MEDLINE 获取 2014 年至 2018 年期间在《关节成形术杂志》和《今日关节成形术》上发表文章的所有作者姓名。财务披露声明来自期刊网站,并与 Open Payments 进行人工比对。统计比较采用卡方检验,显著性定义为 P < .05.Results2014-2018年间,共发表了3147篇文章,4038位作者符合纳入标准。在披露财务信息的作者中,2298 位(57%)作者正确披露了财务信息。已披露的利益冲突总价值为 17.1 亿美元。未披露的利益冲突总价值为 3.34 亿美元。对于 100 万美元的付款,86% 的医生都准确披露了。对于 100 美元至 9999 美元的付款,医生有 26% 的时间准确披露。高级作者正确披露的比例为 72%,明显高于中级作者和第一作者。结论在关节置换手术领域,披露不准确的情况非常普遍,这表明有必要进一步教育早期职业医师什么是COI。披露表格的标准化和与公开支付数据库的验证有助于提高披露的准确率。

Background

This systematic review aims to evaluate the effectiveness and safety of custom femoral stems in primary total hip arthroplasty (THA) for patients with secondary osteoarthritis with abnormal hip anatomy.

Methods

Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, databases were systematically searched for studies published on primary THA utilizing custom femoral stems. Inclusion criteria were studies on patients with secondary osteoarthritis receiving custom stems, with outcomes including implant survival, revision rates, and functional scores. Data were extracted from eligible studies, with a focus on overall and cause-specific revision rates.

Results

A total of 689 studies were screened, 13 met the inclusion criteria, encompassing 806 patients and 951 custom THA procedures. The collective follow-up period averaged 11.6 years, with a mean age of 44.6 years. The mean reoperation and revision rates were 6.9% (95% confidence interval [CI]: 3.24-10.13) and 8.25% (95% CI: 4.02-12.47), respectively. The mean intraoperative fracture rate was 3.23% (95% CI: 1.35-5.11), and the mean postoperative leg length discrepancy was 4.25 mm (95% CI: 1.57-6.93). The mean improvement of postoperative Harris Hip Score was 40.32 (range 30-56).

Conclusions

Custom femoral stems in primary THA demonstrate promising results in terms of implant survival and functional outcomes for patients with complex hip anatomy due to secondary osteoarthritis. These findings support the consideration of custom implants as a viable option for this patient demographic, although further research is warranted for long-term outcomes and direct comparisons with standard prostheses.
背景本系统性综述旨在评估定制股骨柄在髋关节解剖结构异常的继发性骨关节炎患者的初次全髋关节置换术(THA)中的有效性和安全性。方法根据系统性综述和荟萃分析首选报告项目(PRISMA)指南,系统地检索了数据库中已发表的关于使用定制股骨柄的初次全髋关节置换术的研究。纳入标准是关于接受定制股骨柄的继发性骨关节炎患者的研究,研究结果包括植入物存活率、翻修率和功能评分。从符合条件的研究中提取数据,重点关注总体翻修率和特定病因翻修率。结果 共筛选出 689 项研究,13 项符合纳入标准,涉及 806 名患者和 951 例定制 THA 手术。随访时间平均为 11.6 年,平均年龄为 44.6 岁。平均再手术率和翻修率分别为 6.9%(95% 置信区间 [CI]:3.24-10.13)和 8.25%(95% 置信区间 [CI]:4.02-12.47)。术中平均骨折率为3.23%(95% CI:1.35-5.11),术后平均腿长差异为4.25毫米(95% CI:1.57-6.93)。结论:对于因继发性骨关节炎导致髋关节解剖结构复杂的患者,定制股骨柄在初次 THA 中的植入物存活率和功能结果方面显示出良好的前景。这些研究结果支持将定制假体作为这类患者的一种可行选择,但还需要进一步研究长期疗效,并与标准假体进行直接比较。

Prosthetic joint infections (PJIs) following total joint arthroplasties are relatively rare but devastating complications. To date, no cases of Mycobacterium fortuitum PJIs associated with contaminated water supplies have been reported in the literature. Our report details 5 patients with Mycobacterium fortuitum PJIs related to a contaminated water supply at an ambulatory surgical center. These patients were identified by referral to our academic center. All underwent at least 1 revision surgery prior to referral and required prolonged broad-spectrum antibiotics. All had extensive wound complications, and 4 of 5 patients have received at least stage 1 of a 2-stage revision. All will require further surgery, but long-term outcomes remain relatively uncertain.
全关节置换术后的人工关节感染(PJI)是一种相对罕见但却具有破坏性的并发症。迄今为止,还没有文献报道过与供水污染有关的拟杆菌 PJI 病例。我们的报告详细介绍了一家门诊手术中心的 5 例因供水污染而导致的拟杆菌 PJI 患者。这些患者是通过转诊到我们的学术中心而发现的。所有患者在转诊前都至少接受过一次翻修手术,需要长期使用广谱抗生素。所有患者都有广泛的伤口并发症,5 名患者中有 4 名至少接受了两阶段翻修手术中的第一阶段。所有患者都需要进一步手术,但长期结果仍相对不确定。

Synovial fistula of the knee occurs when a defect in the joint capsule creates a connection between skin, bursa, and a near tissue, manifesting as an opening with continuous draining fluid or a cyst. This is a case of an 80-year-old male who developed a synovial fistula with cystic presentation 6 years after the primary total knee arthroplasty. Management included a total knee arthroplasty revision surgery with intraoperative identification of the fistula with methylene blue, and using a gelatin-thrombin matrix for closure. This case shows a possible complication of catastrophic polyethylene insert wear and management.

Avascular necrosis (AVN) of the femoral head accounts for up to 10% of all total hip arthroplasties performed annually. Typically associated with intravascular coagulation, AVN is extremely rare in patients with bleeding disorders such as hemophilia B. In this report, we describe the therapeutic management of a 46-year-old male with hemophilia B, presenting with chronic left hip pain and AVN of the femoral head. He presented with progressive groin pain for 6 months and was unable to ambulate without the assistance of crutches. Radiographs showed evidence of degenerative joint disease secondary to AVN of the femoral head.

Background

Total hip arthroplasty (THA) is one of the most common orthopaedic procedures performed in the United States, but there are rare complications which can be devastating. Sickle cell disease (SCD) can lead to avascular necrosis of the femoral head, often necessitating THA. This article seeks to better characterize the complication risks in patients undergoing THA with SCD when compared to osteoarthritis (OA) using a large database from the National Inpatient Sample.

Methods

National Inpatient Sample data from 2006 through the third quarter of 2015 were analyzed using International Classification of Diseases, Ninth Revision codes. A weighted frequency of 4,350,961 THAs were recorded for OA and 4279 for SCD. These were compared using a Rao-Scott chi-squared test, and the prespecified complications were given sampling weights to approximate national estimates.

Results

The following complications were found to occur at a significantly increased frequency in patients with OA with SCD vs OA only: wound infection (0.69% vs 0.36%), dislocation (1.68% vs 0.80%), and urinary complications (3.61% vs 2.35%). SCD, when evaluated independent of avascular necrosis, was reported with higher frequency wound infection (0.86% vs 0.36%), and overall complications (7.25% vs 5.06%). Additionally, multiple comorbidities were significantly more prevalent in the SCD population compared to OA patients.

Conclusions

This study illustrates that patients with SCD have increased complication rates when compared to OA patients. This information benefits orthopaedic surgeons in preoperative and postoperative planning and counseling patients for realistic expectations. Furthermore, this study provides data that could benefit decision-making on bundled reimbursement for this specific patient population.
背景全髋关节置换术(THA)是美国最常见的骨科手术之一,但也存在一些罕见的并发症,这些并发症可能具有毁灭性。镰状细胞病(SCD)可导致股骨头血管性坏死,通常需要进行全髋关节置换术。本文试图利用全国住院病人抽样调查的大型数据库,更好地描述与骨关节炎(OA)相比,接受 THA 手术的 SCD 患者的并发症风险。方法利用国际疾病分类第九版代码分析了 2006 年至 2015 年第三季度的全国住院病人抽样调查数据。根据加权频率记录,OA 的 THAs 数量为 4,350,961 例,SCD 的 THAs 数量为 4279 例。结果发现以下并发症在伴有 SCD 的 OA 患者和仅伴有 OA 的患者中发生的频率显著增加:伤口感染(0.69% vs 0.36%)、脱位(1.68% vs 0.80%)和泌尿系统并发症(3.61% vs 2.35%)。在独立于血管性坏死进行评估时,SCD的伤口感染(0.86% vs 0.36%)和整体并发症(7.25% vs 5.06%)发生率较高。结论这项研究表明,与 OA 患者相比,SCD 患者的并发症发生率更高。这一信息有利于矫形外科医生制定术前和术后计划,并向患者提供切合实际期望的咨询服务。此外,本研究提供的数据还有利于针对这一特殊患者群体的捆绑报销决策。

Background

The utilization of social media for health-related purposes has surged, especially during the COVID-19 pandemic. TikTok, a short-form video platform, has seen substantial growth, becoming a prominent medium for health information dissemination. However, the lack of regulation poses challenges in evaluating the validity of TikTok content.

Methods

This cross-sectional study assesses TikTok videos related to total knee arthroplasty rehabilitation exercises. Search terms identified 84 videos, with 64 meeting the inclusion criteria. Engagement metrics and quality scores were analyzed, utilizing the DISCERN tool and the Total Knee Replacement Exercises Education Score.

Results

The analyzed videos accumulated nearly 6 million views, with a median of 10,293.5 (interquartile range = 4139.3-26,100.0). Health-care professionals contributed 48% of the content. Despite higher engagement metrics for health-care professional videos, the overall quality, as indicated by DISCERN and Total Knee Replacement Exercises Education scores, remained poor. No videos achieved an “excellent” rating, with the majority categorized as “poor.”

Conclusions

This study underscores TikTok’s substantial role in total knee arthroplasty rehabilitation information dissemination but reveals a critical deficit in content quality and reliability. Health-care professionals marginally outperformed general users but displayed overall inadequacy. The study emphasizes the necessity for improving the quality of health-related content on emerging social media platforms, especially within the realm of orthopaedic surgery.

Level of Evidence

Level III, Cross-sectional study.
背景社交媒体在健康相关领域的使用激增,尤其是在 COVID-19 大流行期间。短视频平台 TikTok 增长迅速,已成为传播健康信息的重要媒介。本横断面研究评估了与全膝关节置换术康复锻炼相关的 TikTok 视频。通过搜索词确定了 84 个视频,其中 64 个符合纳入标准。利用DISCERN工具和全膝关节置换术锻炼教育评分对参与度指标和质量评分进行了分析。结果分析的视频累计观看次数近600万次,中位数为10293.5次(四分位间范围=4139.3-26100.0)。医护人员贡献了 48% 的内容。尽管医护人员视频的参与度指标较高,但从 DISCERN 和全膝关节置换运动教育评分来看,整体质量仍然较差。本研究强调了 TikTok 在全膝关节置换术康复信息传播中的重要作用,但也揭示了内容质量和可靠性方面的严重不足。医疗保健专业人员的使用率略高于普通用户,但总体表现不佳。该研究强调了提高新兴社交媒体平台上健康相关内容质量的必要性,尤其是在矫形外科领域。
