Abstract

:Despite the evolution of blood management protocols, total knee arthroplasty (TKA) occasionally requires allogeneic blood transfusion. This poses a particular challenge for Jehovah's Witnesses (JW) who believe that the Bible strictly prohibits the use of blood products. The aim of this study was to compare JW and a matched-control cohort of non-JW candidates undergoing TKA to assess the safety using modern blood management protocols. Fifty-five JW patients (63 knees) who underwent TKA at our institution between 2005 and 2017 were matched to 63 non-JW patients (63 knees). Patient demographics, intraoperative details, and postoperative complications including in-hospital complications, revisions, and 90-day readmissions were collected and compared between the groups. Additionally, subgroup analysis was performed comparing JW patients who were administered tranexamic acid (TXA) between the two groups. Baseline demographics did not vary significantly between the study cohorts. The mean follow-up was 3.1 years in both the JW and non-JW cohorts. Postoperative complications, including in-hospital complications (7.9 vs. 4.8%; p = 0.47), revision TKA (1.6 vs. 1.6%; p = 1.00), and 90-day readmission (1.6 vs. 4.8%; p = 0.31) were not significantly different between the JW and non-JW groups. Subgroup analysis demonstrated JW patients who received TXA had a significantly lower decline in postoperative hemoglobin (Hgb) (8.6 vs. 14.0%; p < 0.01). At a follow-up of up to 12 years, JW patients who underwent TKA have outcomes equivalent to non-JW patients without the need for transfusion. Our findings support that surgeons are more likely to optimize JW patients preoperatively with iron and folate supplementation. Despite these variations in preoperative optimization efforts, no significant difference with regard to Hgb or hematocrit levels was demonstrated. Level of evidence is III, retrospective observational study.

摘要

: 尽管血液管理方案的演变,全膝关节置换术 (TKA) 偶尔需要异体输血。这对耶和华见证人 (JW) 来说是一个特别的挑战,他们认为圣经严格禁止使用血液制品。本研究的目的是比较接受TKA的JW和非JW候选者的匹配对照队列,以评估使用现代血液管理方案的安全性。2005 年至 2017 年期间在我们机构接受TKA的 55 例JW患者 (63 膝) 与 63 例非JW患者 (63 膝) 相匹配。收集患者人口统计学资料、术中细节和术后并发症,包括住院并发症、翻修和 90 天再入院,并在组间进行比较。此外,对两组给予氨甲环酸 (TXA) 的JW患者进行亚组分析。基线人口统计学在研究队列之间没有显著差异。JW和非JW队列的平均随访时间均为 3.1 年。术后并发症,包括院内并发症 (7.9 vs. 4.8%; P = 0.47),翻修TKA (1.6 vs. 1.6%; P = 1.00) 和 90 天再入院 (1.6 vs. 4.8%; P = 0.31) 在JW组和非JW组之间无显著差异。亚组分析显示接受TXA的JW患者术后血红蛋白 (Hgb) 下降幅度显著较低 (8.6 vs. 14.0%; P <0.01)。在长达 12 年的随访中,接受TKA的JW患者的结局与非JW患者相当,无需输血。我们的研究结果支持外科医生更有可能优化JW患者术前补充铁和叶酸。尽管术前优化工作存在这些差异,但未显示Hgb或血细胞比容水平方面的显著差异。证据水平为III级,回顾性观察性研究。

METHODS:BACKGROUND:Postoperative cognitive dysfunction (POCD) is a common complication after orthopedic surgery, which is not conducive to the prognosis of the elderly. AIMS:We performed this study to investigate the effects of oxycodone applied for patient-controlled intravenous analgesia (PCIA) on postoperative cognitive function in elderly patients after total hip arthroplasty (THA). METHODS:Ninety-nine participants were enrolled and allocated into two groups: oxycodone group (group O) and sufentanil group (group S). The primary outcome was the incidence of POCD, diagnosed according to the changes in the Mini-mental status examination (MMSE) and Montreal Cognitive Assessment (MoCA) scores. The secondary outcomes included the plasma levels of S-100B protein and neuron-specific enolase (NSE), the amount of postoperative analgesic consumption and the incidence of adverse reactions. RESULTS:The incidence of POCD was significantly lower in patients receiving oxycodone up to the 3rd postoperative day (POD, 1st POD 27.3% vs. 51.1%, P = 0.021; 3rd POD 20.5% vs. 40.0%, P = 0.045), as compared to patients receiving sufentanil. The MMSE and MoCA scores of both groups decreased to varying degrees. However, compared with group S, the MMSE scores at 1st POD, 3rd POD, 5th POD and 7st POD in group O were higher than that in group S, while MoCA scores at 1st POD, 3rd POD and 5th POD in group O were higher. Compared with group S, the plasma levels of S-100B protein in group O at 4 h, 8 h, 12 h post-surgery were lower. While the plasma levels of NSE in group O at 4 h, 8 h, 12 h, 24 h post-surgery were lower. Number of PCIA boluses and consumption of analgesic drug during the first two POD were similar between two groups. However, postoperative incidence of nausea, vomiting and pruritus was significantly lower in patients receiving oxycodone. CONCLUSION:Oxycodone applied for PCIA in elderly patients after THA could reduce the incidence of POCD, improve postoperative cognitive function and decrease the adverse reactions.

METHODS:BACKGROUND:Primary treatment for Blount disease has changed in the last decade from osteotomies or staples to tension band plate (TBP)-guided hemiepiphysiodesis. However, implant-related issues have been frequently reported with Blount cases. The purpose of our study is to evaluate the surgical failure rates of TBP in Blount disease and characterize predictors for failure. METHODS:We performed an Institutional Review Board-approved retrospective chart-review of pediatric patients with Blount disease to evaluate the results of TBP from 2008 to 2017 and a systematic literature review. Blount cases defined as pathologic tibia-vara with HKA (hip-knee-ankle) axis and MDA (metaphyseal-diaphyseal angle) deviations ≥11 degrees were included in the analysis. Surgical failure was categorized as mechanical and functional failure. We studied both patient and implant-related characteristics and compared our results with a systematic review. RESULTS:In 61 limbs of 40 patients with mean follow-up of 38 months, we found 41% (25/61) overall surgical failure rate and 11% (7/61) mechanical failure rate corresponding to 11% to 100% (range) and 0% to 50% (range) in 8 other studies. Statistical comparison between our surgical failure and nonfailure groups showed significant differences in deformity (P=0.001), plate material (P=0.042), and obesity (P=0.044) in univariate analysis. The odds of surgical failure increased by 1.2 times with severe deformity and 5.9 times with titanium TBP in the multivariate analysis after individual risk-factor adjustment. All 7 mechanical failures involved breakage of cannulated screws on the metaphyseal side. CONCLUSIONS:Most of the studies have reported high failure rates of TBP in Blount cases. Besides patient-related risk factors like obesity and deformity, titanium TBP seems to be an independent risk factor for failure. Solid screws were protective for mechanical failure, but not for functional failure. In conclusion, efficacy of TBP still needs to be proven in Blount disease and implant design may warrant reassessment. LEVEL OF EVIDENCE:Level III-retrospective comparative study with a systematic review.

METHODS:INTRODUCTION:As cancer treatments continue to improve the overall survival rates, more patients with a history of cancer will present for anatomic total shoulder arthroplasty (TSA). Therefore, it is essential for orthopaedic surgeons to understand the differences in care required by this growing subpopulation. Although the current research suggests that good outcomes can be predicted when appropriately optimized patients with cancer undergo lower extremity total joint arthroplasty, similar studies for TSA are lacking. The primary study question was to examine whether a history of cancer was associated with an increased rate of venous thromboembolism (VTE) after TSA. Secondarily, we sought to examine any association between a history of prostate and breast cancer and surgical or medical complications after TSA. METHODS:Using a national insurance database, male patients with a history of prostate cancer and female patients with a history of breast cancer undergoing anatomic TSA for primary osteoarthritis were identified and compared with control subjects matched 3:1 based on age, sex, diabetes mellitus, and tobacco use. Patients with a history of VTE and patients who underwent reverse TSA or hemiarthroplasty were excluded. RESULTS:Female patients with a history of breast cancer and male patients with a history of prostate cancer undergoing TSA had significantly higher incidences of acute VTE (including deep venous thrombosis and pulmonary embolism) compared with matched control subjects (female patients: odds ratio, 1.41; 95% confidence interval, 1.10 to 1.81; P = 0.024 and male patients: odds ratio, 1.37; 95% confidence interval, 1.05 to 1.79; P = 0.023). No significant differences were noted in the incidences of any other complications assessed. CONCLUSION:Although a personal history of these malignancies does represent a statistically significant risk factor for acute VTE after anatomic TSA, the overall VTE rate remains modest and acceptable. The rates of other surgical and medical complications are not significantly increased in patients with a history of these cancers after TSA compared with control subjects.
