Background

There are high reported rates of burnout and job turnover among orthopedic surgeons. The purpose of this study was to investigate the prevalence of job change among early-career adult reconstruction surgeons and to examine which demographic or practice factors influenced job change.

Methods

An electronic survey was distributed to all practicing surgeon members of the American Association of Hip and Knee Surgeons Young Arthroplasty Group. The survey included questions about practice type, demographics, job change, and a validated burnout questionnaire. Survey responses were collected using a secure database. Statistical analysis was performed to examine relationships between respondent characteristics and job change.

Results

There were 201/389 responses (51.7%). The most common motivators for job change were better workplace culture (64%), opportunities for career growth (52%), and better alignment with values of the department/institution (45%). There were few female respondents; however, they trended toward reporting higher rates of job change (35.6% female vs 21.3% male, P = .3). Respondents who were considering changing jobs but had not done so were significantly more likely to report symptoms of burnout in all studied subscales: emotional exhaustion (P < .0001), depersonalization (P = .0002), and sense of personal accomplishment (P = .007).

Conclusions

Surgeons changing jobs cited social factors such as workplace culture as reasons for leaving. Burnout symptoms were higher in surgeons considering changing jobs but improved in those who had already changed jobs. It is important to identify factors that lead to job change to guide young surgeons in job selection and improve retention.

背景据报道，骨科外科医生的职业倦怠和离职率很高。本研究旨在调查早期职业生涯的成人重建外科医生中工作变动的普遍程度，并研究哪些人口统计学或实践因素会影响工作变动。方法向美国髋关节和膝关节外科医生协会青年关节成形术小组的所有执业外科医生成员发放电子调查表。调查内容包括有关执业类型、人口统计学、工作变动的问题，以及一份经过验证的职业倦怠问卷。调查回复是通过安全数据库收集的。结果共有 201/389 份回复（51.7%）。最常见的跳槽动机是更好的工作场所文化（64%）、职业发展机会（52%）以及更好地与部门/机构的价值观保持一致（45%）。女性受访者人数较少，但她们的跳槽率呈上升趋势（35.6% 的女性对 21.3% 的男性，P = .3）。正在考虑更换工作但尚未更换工作的受访者在所有研究分量表中报告职业倦怠症状的可能性明显更高：情感衰竭（P = 0.0001）、人格解体（P = 0.0002）和个人成就感（P = 0.007）。结论更换工作的外科医生将工作场所文化等社会因素作为离职的原因。考虑更换工作的外科医生的职业倦怠症状较高，但已经更换工作的外科医生的职业倦怠症状有所改善。确定导致换工作的因素对于指导年轻外科医生选择工作和留住人才非常重要。

Background

Leg-length discrepancy (LLD) can lead to patient dissatisfaction and decreased function after total hip arthroplasty (THA). This study examines the impact of intraoperative fluoroscopy on the magnitude and incidence of LLD after THA.

Methods

Patients undergoing primary THA were identified and stratified into cohorts based on one out of 4 surgical approaches and intraoperative fluoroscopy use. The most recent 100 patients matching each cohort were included. Preoperative and postoperative LLD was assessed radiographically via an interteardrop reference line to lesser trochanter measurement.Magnitude of LLD and the proportion of patients in each cohort with LLD >5 mm, >10 mm, and 15 mm were analyzed.

Results

Four hundred patients were stratified into 4 equal cohorts. Overall, THA done with fluoroscopy yielded fewer leg length discrepancies than THA done without fluoroscopy. The anterior-based muscle sparing (ABMS) approach with fluoroscopy had significantly less postoperative LLD than the posterior approach without fluoroscopy (3.4 vs 5.1 mm, P < .01) and the ABMS approach in the lateral position without fluoroscopy (3.4 vs 4.8 mm, P = .03). For LLD >5 mm, the ABMS approach with fluoroscopy cohort had significantly fewer patients compared to the ABMS approach without fluoroscopy (23 vs 41, P < .01). For LLD >10 mm, the ABMS approach with fluoroscopy cohort had significantly fewer patients compared to the posterior approach without fluoroscopy (2 vs 15, P < .01). For LLD >15 mm, relative to the posterior approach without fluoroscopy, all other cohorts had significantly fewer outliers (P < .02).

Conclusions

This study supplies evidence that use of intraoperative fluoroscopy is likely beneficial in reducing the magnitude of LLD following THA and reducing the incidence of outlier LLDs >5 mm, >10 mm, and <15 mm.

背景全髋关节置换术（THA）后，腿长不一致（LLD）会导致患者不满意和功能下降。本研究探讨了术中透视对 THA 术后 LLD 的程度和发生率的影响。方法对接受初级 THA 的患者进行鉴定，并根据 4 种手术方法中的一种以及术中透视的使用情况将其分为若干队列。每个队列都纳入了最近的 100 名匹配患者。通过心尖间参考线到小转子的测量，对术前和术后 LLD 进行影像学评估。分析 LLD 的大小以及每个队列中 LLD 为 5 mm、10 mm 和 15 mm 的患者比例。总体而言，与不进行透视的 THA 相比，进行透视的 THA 产生的腿长偏差更少。透视下的前路肌肉疏松（ABMS）方法的术后LLD（3.4 vs 5.1 mm，P = .01）明显少于无透视的后路方法（3.4 vs 4.8 mm，P = .03），无透视的侧位ABMS方法的术后LLD（3.4 vs 4.8 mm，P = .03）也明显少于无透视的侧位ABMS方法（3.4 vs 4.8 mm，P = .03）。对于 LLD >5毫米，与不进行透视的 ABMS 方法相比，进行透视的 ABMS 方法的患者人数明显较少（23 对 41，P < .01）。对于 LLD >10毫米，有透视的 ABMS 方法队列中的患者数量明显少于无透视的后部方法队列（2 vs 15，P < .01）。结论本研究提供的证据表明，使用术中透视可能有利于降低 THA 术后 LLD 的幅度，并减少 LLDs >5mm、>10mm 和 <15mm离群的发生率。

Background

Arthroplasty registries play a critical role in improving the quality of care and performing post-market surveillance of medical devices. We report the Michigan Arthroplasty Registry Collaborative Quality Initiative (MARCQI) findings specific to the Biomet Vanguard XP bicruciate-retaining total knee implant.

Methods

Data were collected from MARCQI’s 2019 report (February 15, 2012, through December 31, 2018). Demographic data were analyzed to determine differences between Vanguard XP and all other implants. The cumulative percent revision (CPR) was computed from the survival function, S(t), using CPR(t) = 100∗(1 − S(t)). A log-rank test was used to assess differences in the CPR curve for the Vanguard XP and all other implants.

Results

There were 148,832 knee arthroplasty cases in the MARCQI registry and 507 using Vanguard XP implant combinations. The unadjusted cumulative percent revision curve up to 5 years postoperatively for the Vanguard XP differed from all other implants (P < .0001). The hazard ratios for the 3 factors included in the Cox proportional hazards model were all significantly different from unity: implant (2.76, 95% CI: 1.98-3.86), sex (0.80, 95% CI: 0.74-0.85), and age (0.96, 95% CI: 0.96-0.97). The top 3 reasons for revision were pain, arthrofibrosis, and aseptic loosening. All surgeons who used the Vanguard XP experienced higher failure rates.

Conclusions

The Vanguard XP experienced higher early failure rates than other TKA implants within the MARCQI registry. The development of thresholds and benchmarks for registry reporting in collaboration with industry could potentially save patients from the morbidity caused by implants that do not perform as well as anticipated.

背景关节成形术注册机构在提高医疗质量和对医疗器械进行上市后监测方面发挥着至关重要的作用。我们报告了密歇根关节成形术注册协作质量倡议（MARCQI）针对Biomet Vanguard XP双椎体固位全膝关节植入物的调查结果。方法从MARCQI的2019年报告（2012年2月15日至2018年12月31日）中收集数据。对人口统计学数据进行了分析，以确定 Vanguard XP 与所有其他植入物之间的差异。根据存活函数 S(t)，计算出累积修正百分比 (CPR)，即 CPR(t) = 100∗(1-S(t))。结果MARCQI登记处共有148832例膝关节置换术病例，其中507例使用了Vanguard XP植入物组合。Vanguard XP术后5年的未调整累积翻修率曲线与所有其他假体不同（P < .0001）。Cox比例危险模型中包含的三个因素的危险比均与统一值有显著差异：种植体（2.76，95% CI：1.98-3.86）、性别（0.80，95% CI：0.74-0.85）和年龄（0.96，95% CI：0.96-0.97）。翻修的前三位原因分别是疼痛、关节纤维化和无菌性松动。结论在 MARCQI 登记中，Vanguard XP 的早期失败率高于其他 TKA 植入物。与业界合作制定登记报告的阈值和基准可能会使患者免于因植入物性能不如预期而导致的发病率。

Multiple epiphyseal dysplasia is a rare congenital disorder characterized by irregular, delayed ossification at multiple epiphyses, typically in the lower extremity. In this arthroplasty in rare conditions case report, we present a 14-year-old female with multiple epiphyseal dysplasia and borderline acetabular dysplasia who developed progressive bilateral femoral head avascular necrosis. She presented with a worsening antalgic gait and bilateral hip pain starting at 10 years of age, which was refractory to nonoperative measures. She was treated with staged bilateral total hip arthroplasty when her triradiate cartilage was closed and is presenting with 3 years of clinical follow-up with excellent reported outcomes. The goal of this case presentation is to discuss the specific surgical challenges related to this patient population and highlight important considerations in the adolescent population undergoing total hip arthroplasty.

多发性骺发育不良是一种罕见的先天性疾病，其特点是多个骺端不规则、延迟骨化，通常发生在下肢。在这份罕见病例的关节置换术病例报告中，我们介绍了一名患有多发性骺发育不良和边缘性髋臼发育不良的 14 岁女性患者，她的双侧股骨头发生了进行性血管性坏死。她在 10 岁时开始出现日益加重的蚁行步和双侧髋关节疼痛，非手术治疗无效。当她的三桡骨软骨闭合时，她接受了分期双侧全髋关节置换术治疗，目前临床随访3年，疗效极佳。本病例旨在讨论与该患者群体相关的特殊手术挑战，并强调青少年群体接受全髋关节置换术的重要注意事项。

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。
