Abstract
Aims The aims of this study were to identify and evaluate the current literature examining the prognostic factors which are associated with failure of total elbow arthroplasty (TEA). Methods Electronic literature searches were conducted using MEDLINE, Embase, PubMed, and Cochrane. All studies reporting prognostic estimates for factors associated with the revision of a primary TEA were included. The risk of bias was assessed using the Quality In Prognosis Studies (QUIPS) tool, and the quality of evidence was assessed using the modified Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) framework. Due to low quality of the evidence and the heterogeneous nature of the studies, a narrative synthesis was used. Results A total of 19 studies met the inclusion criteria, investigating 28 possible prognostic factors. Most QUIPS domains (84%) were rated as moderate to high risk of bias. The quality of the evidence was low or very low for all prognostic factors. In low-quality evidence, prognostic factors with consistent associations with failure of TEA in more than one study were: the sequelae of trauma leading to TEA, either independently or combined with acute trauma, and male sex. Several other studies investigating sex reported no association. The evidence for other factors was of very low quality and mostly involved exploratory studies. Conclusion The current evidence investigating the prognostic factors associated with failure of TEA is of low or very low quality, and studies generally have a moderate to high risk of bias. Prognostic factors are subject to uncertainty, should be interpreted with caution, and are of little clinical value. Higher-quality evidence is required to determine robust prognostic factors for failure of TEA.

Foregoing Preoperative Antibiotics in Clean, Implant-Based Hand Surgery Does Not Increase Postoperative Infectious Risks. JOURNAL OF HAND SURGERY GLOBAL ONLINE 2024; 6:338-343.

Abstract
Purpose Although data support foregoing preoperative antibiotics for outpatient, soft-tissue procedures, there is a paucity of evidence regarding antibiotics for implant-based hand procedures. The purpose of this investigation was to assess early postoperative infectious concerns for patients undergoing implant-based hand surgery, regardless of preoperative antibiotic use. Methods A retrospective cohort analysis was performed consisting of all patients undergoing implant-based hand procedures between January 2015 and October 2021. Primary outcomes included antibiotic prescription or reoperation for infection within 90 days of surgery. Demographics (age, gender, body mass index, diabetes, and smoking status) and hand surgery procedure type were recorded. To account for differences in baseline characteristics between patients who did and did not receive preoperative antibiotics, covariate balancing was performed with subsequent weighted logistic regression models constructed to estimate the effect of no receipt of preoperative antibiotics on the need for postoperative antibiotics. In a separate logistic regression analysis, patients' baseline characteristics were evaluated together as predictors of postoperative antibiotic prescription. Results One thousand eight hundred sixty-two unique procedures were reviewed with 1,394 meeting criteria. Two hundred thirty-six patients (16.9%) were not prescribed preoperative antibiotics. Overall, 54 (3.87%) and 69 (4.95%) patients received antibiotics within 30 and 90 days of surgery, respectively. One patient (0.07%) underwent reoperation. There were no differences in the rates of 30- and 90-day postoperative antibiotic prescriptions between the two groups. After covariant balancing of risk factors, patients not prescribed preoperative antibiotics did not display significantly higher odds of requiring postoperative antibiotics at 30 or 90 days. Logistic regression models showed male gender, temporary Kirschner wire fixation, and elevated body mass index were associated with increased postoperative antibiotics at 30 and 90 days. Conclusions For implant-based hand procedures, there was no increased risk in postoperative antibiotic prescription or reoperation for patients who did not receive preoperative antibiotics. Type of study/level of evidence Therapeutic III.

Distal humeral hemiarthroplasty compared to total elbow replacement for distal humeral fractures: a registry analysis of 906 procedures. J Shoulder Elbow Surg 2024; 33:356-365. [PMID: 37689104 DOI: 10.1016/j.jse.2023.08.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Revised: 08/01/2023] [Accepted: 08/06/2023] [Indexed: 09/11/2023]
Abstract
BACKGROUND Total elbow replacement (TER) is an accepted treatment for complex intra-articular distal humerus fractures in elderly patients. Distal humeral hemiarthroplasty (HA) is also a potential surgical option for unreconstructable fractures and avoids the concerns regarding mechanical wear and functional restrictions associated with TER. In the current literature, there are limited data available to compare the revision rates of HA and TER for the treatment of fracture. We used data from a large national arthroplasty registry to compare the outcome of HA and TER undertaken for fracture/dislocation and to assess the impact of demographics and implant choice on revision rates. METHODS Data obtained from the Australian Orthopaedic Association National Joint Replacement Registry from May 2, 2005, to December 31, 2021, included all procedures for primary elbow replacement with primary diagnosis of fracture or dislocation. The analyses were performed using Kaplan-Meier estimates of survivorship and hazard ratios (HRs) from Cox proportional hazards models. RESULTS There were 293 primary HA and 631 primary TER procedures included. The cumulative percentage revision (CPR) rate at 9 years was 9.7% for HA (95% confidence interval [CI] 6.0, 15.7), and 11.9% (95% CI 8.5, 16.6) for TER. When adjusted for age and gender, there was a significantly higher risk of revision after 3 months for TER compared to HA (HR 2.47, 95% CI 1.22, 5.03, P = .012). There was no difference in the rate of revision for patients aged <55 years or ≥75 years when HA and TER procedures were compared. In primary TER procedures, loosening was the most common cause of revision (3.6% of primary TER procedures), and the most common type of revision in primary TER involved revision of the humeral component only (2.6% of TER procedures). TER has a higher rate of first revision for loosening compared to HA (HR 4.21, 95% CI 1.29, 13.73; P = .017). In HA procedures, instability (1.7%) was the most common cause for revision. The addition of an ulna component was the most common type of revision (2.4% of all HA procedures). CONCLUSION For the treatment of distal humerus fractures, HA had a lower revision rate than TER after 3 months when adjusted for age and gender. Age <55 or ≥75 years was not a risk factor for revision when HA was compared to TER. Loosening leading to revision is more prevalent in TER and increases with time. In HA, the most common type of revision involved addition of an ulna component with preservation of the humeral component.

Abstract
BACKGROUND Semiconstrained total elbow arthroplasty (TEA) is an established treatment for elderly patients with distal humeral fractures not amenable to stable internal fixation (unreconstructable). In recent years, there has been increasing interest in elbow hemiarthroplasty (EHA), a treatment option which does not entail restrictions on weight-bearing as opposed to TEA. These 2 treatments have not been compared in a randomized controlled trial (RCT). The aim of this study was to compare the functional outcome of EHA and TEA for the treatment of unreconstructable distal humeral fractures in elderly patients. MATERIAL AND METHODS This was a multicenter randomized controlled trial (RCT). Patients were included between January 2011 and November 2019 at one of 3 participating hospitals. The inclusion criteria were an unreconstructable distal humeral fracture, age ≥60 years and independent living. The final follow-up took place after ≥2 years. The primary outcome measure was the Disabilities of the Arm, Shoulder, and Hand (DASH) score. Secondary outcome measures were the Mayo Elbow Performance Score (MEPS), the EQ-5D index, range of motion (flexion, extension, pronation, and supination) and grip strength. RESULTS Forty patients were randomized to TEA (n = 20) and EHA (n = 20). Five patients died before completing the final follow-up, leaving 18 EHA and 17 TEA patients for analysis. There were 31 women. The mean age was 74.0 (SD, 8.5) years in the EHA group and 76.9 (SD, 7.6) in the TEA group (P = .30). The mean DASH score was 21.6 points in the EHA group and 27.2 in the TEA group (P = .39), a difference of -5.6 points (95% CI: -18.6 to 7.5). There were no differences between treatment with EHA and TEA for the mean values of the MEPS (85.0 vs. 88.2, P = .59), EQ-5D index (0.92 vs. 0.86, P = .13), extension (29° vs. 29°, P = .98), flexion (126° vs. 136°, P = .05), arc of flexion-extension (97° vs. 107°, P = .25), supination (81° vs. 75°, P = .13), pronation (78° vs. 74°, P = .16) or grip strength (17.5 kg vs. 17.2 kg, P = .89). There were 6 adverse events in each treatment group. CONCLUSION In this RCT, both elbow hemiarthroplasty (EHA) and total elbow arthroplasty (TEA) resulted in a good and similar functional outcome for unreconstructable distal humeral fractures in elderly patients at a minimum of 2 years of follow-up.

Abstract
INTRODUCTION Total elbow replacement (TER) has higher failure rates requiring revision surgery compared with the replacement of other joints. Understanding the factors associated with failure is essential for informed decision-making between patients and clinicians, and for reducing the failure rate. This review aims to identify, describe and appraise the literature examining prognostic factors for failure of TER. METHODS AND ANALYSIS This systematic review will be conducted and reported in line with the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols guidelines. Electronic literature searches will be conducted using Medline, EMBASE, PubMed and Cochrane. The search strategy will be broad, including a combination of subject headings (MESH) and free text search. This search will be supplemented with a screening of reference lists of the included studies and relevant reviews. Two independent reviewers will screen all search results in two stages (title and abstract, and full text) based on the Population, Index prognostic factor, Comparator prognostic factor, Outcome, Time and Setting criteria. The types of evidence included will be randomised trials, non-randomised trials, prospective and retrospective cohort studies, registry studies and case-control studies. If the literature lacks enough studies, then case series with 50 or more TERs will be considered for inclusion. Data extraction and risk of bias assessment for included studies will be performed by two independent reviewers using the Checklist for Critical Appraisal and Data Extraction for Systematic Reviews of Prediction Modelling Studies for Prognostic Factors and Quality In Prognostic Studies tools.Meta-analyses of prognostic estimates for each factor will be undertaken for studies that are deemed to be sufficiently robust and comparable. Several challenges are likely to arise due to heterogeneity between studies, therefore, subgroup and sensitivity analyses will be performed to account for the differences between studies. Heterogeneity will be assessed using Q and I2 statistics. If I2>40% then pooled estimates will not be reported. When quantitative synthesis is not possible, a narrative synthesis will be undertaken. The quality of the evidence for each prognostic factor will be assessed using the Grades of Recommendation Assessment, Development and Evaluation tool. PROSPERO REGISTRATION NUMBER CRD42023384756.

[PMID: 36918118 DOI: 10.1016/j.jse.2023.02.124] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2021] [Revised: 02/01/2023] [Accepted: 02/05/2023] [Indexed: 03/16/2023]
Abstract
BACKGROUND Modification of total elbow arthroplasty (TEA) implants may be necessary in selected patients with substantial anatomic bone deformity or those undergoing revision surgery. The purpose of this study was to investigate the prevalence and consequences of implant modifications during TEA at our institution. We hypothesized that TEA implant modification would be more common in revisions than in primary replacements, and that it would not be associated with worse clinical outcomes or increased rates of radiographic or surgical complications directly related to the implant modification. METHODS Elbows that had undergone TEA by any of 3 surgeons at our institution with use of intraoperative implant modification between January 1992 and October 2019 were retrospectively reviewed for the type of modification and complications. Complications were classified as definitely related, probably related, possibly related, or nonrelated to the implant's modification according to the consensus review by the 3 senior surgeons. A survey was sent out to surgeons outside of our institution to investigate whether intraoperative modification to TEA implants is a common clinical practice. RESULTS A total of 106 implant components were modified during 94 of 731 TEA procedures (13%) in 84 of 560 patients. Implant modifications were performed in 60 of 285 revision cases (21%) compared with 34 of 446 (8%) primary cases (P < .0001). These included shortening the stem in 40 (44%), bending the stem in 16 (15%), notching the stem in 16 (15%), tapering the stem in 9 (9%), and a combination of 2 or more of these modifications in 19 implants (17%). Among the 55 index surgeries available for complication analysis, 40 complications occurred in 28 index surgeries (11 primary and 17 revisions; 25 patients), making the overall complication rate 51%. Of these 40 complications, 23 were considered independent of any implant modification. Of the remaining 17 complications, 9 were considered nonrelated to the implant modification, 6 were possibly related, and 2 were probably related to the implant modification. Therefore, the complication rate possibly related or probably related to implant modification was 15% (8 of 55). No complication was classified as definitely related to the implant modification. No implant breakage or malfunction occurred after any modification. A total of 442 survey responses were received representing 29 countries, of which 144 surgeons (39%) performed modification to implants during TEA procedures. DISCUSSION This study confirmed our hypothesis that modification of TEA implants is not uncommon at our institution, particularly in revision arthroplasty. Surgeons should keep in mind that complications possibly related or probably related to implant modification were at minimum 15% and could have been as high as 30% if the patients lost to follow-up had all had complications. Implant modification may be necessary in some cases but should be exercised with thoughtful consideration and caution.

Abstract
The aim of this study is to report the implant survival and factors associated with revision of total elbow arthroplasty (TEA) using data from the Dutch national registry. All TEAs recorded in the Dutch national registry between 2014 and 2020 were included. The Kaplan-Meier method was used for survival analysis, and a logistic regression model was used to assess the factors associated with revision. A total of 514 TEAs were included, of which 35 were revised. The five-year implant survival was 91%. Male sex, a higher BMI, and previous surgery to the same elbow showed a statistically significant association with revision (p < 0.036). Of the 35 revised implants, ten (29%) underwent a second revision. This study reports a five-year implant survival of TEA of 91%. Patient factors associated with revision are defined and can be used to optimize informed consent and shared decision-making. There was a high rate of secondary revisions.

Abstract
Introduction Total elbow arthroplasty (TEA) is an increasingly popular surgical option for many debilitating conditions of the elbow. There currently exists a paucity of literature regarding patient and hospital factors that lead to inferior outcomes following TEA. The purpose of this study is to identify independent predictors of increased complication and revision rates following TEA. Methods The National Readmissions Database (NRD) was queried from 2011 to 2018 to identify all cases of TEA (n = 8932). Relevant patient demographic factors, comorbidities, and hospital characteristics were identified and run in a univariate binomial logistic regression model. All significant variables were included in a multivariate binomial logistic regression model for data analysis. Results Independent predictors of increased complication rates included age, female sex, Medicare and Medicaid payer status, medium bed-sized center, and 18 of 34 medical comorbidities (all P < .05). Independent predictors of increased revision rates included medium bed-sized centers, non-teaching hospital status, chronic pulmonary disease, depression, and pulmonary circulatory disorders (all P < .05). Conclusion This study identified several patient and hospital characteristics that are independently associated with both increased complication and revision rates following TEA. This information can aid orthopedic surgeons during shared decision making when considering TEA in patients. Level of Evidence Level III, retrospective cohort study.

The Impact of Cement Mantle Characteristics on Early Loosening in Primary Total Elbow Arthroplasty. J Hand Surg Am 2022; 47:1146-1156. [PMID: 36216682 DOI: 10.1016/j.jhsa.2022.07.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/04/2022] [Revised: 06/15/2022] [Accepted: 07/29/2022] [Indexed: 11/05/2022]
Abstract
PURPOSE To assess the association between cement mantle characteristics and early radiographic loosening in total elbow arthroplasty (TEA). We aimed to determine whether shorter mantle heights (<20 mm) were associated with loosening. METHODS We reviewed primary TEAs from a single healthcare system from 2006 to 2020. TEAs complicated by infection or performed for oncologic conditions were excluded. Initial postoperative radiographs were reviewed to determine cement mantle and component characteristics (mantle quality, mantle height, and component angulation). One-year postoperative radiographs were reviewed to assess for implant loosening, and we compared demographics and radiographic criteria for cases with and without early loosening. We noted whether cases underwent subsequent revision for aseptic osteolysis. RESULTS A total of 54 TEA cases were included. Forty percent of ulnar and 24% of humeral mantles were classified as short (between 1 and 19 mm). According to the Morrey classification, 6 (11%) cases had an inadequate cement mantle Twenty-four (45%) cases had radiographic evidence of loosening at 1 year. Of the cases with early loosening, 6 (25%) had initial inadequate mantle quality. There were no inadequate mantles in the group without loosening. There were no statistically significant differences in mantle heights for cases with and without loosening at 1 year after surgery. Eight (33%) cases underwent revision in the group with early loosening compared with 1 (3%) case without early loosening. CONCLUSIONS Inadequate cement mantle quality was associated with an increased risk of early aseptic loosening after primary TEA. Cement mantles that extended past the tip of the prosthesis were not associated with loosening. Considering the potential need for future revision and morbidity of cement removal, surgeons should focus on mantle quality and carefully plan mantle height because shorter heights may not be associated with early implant failure.

Abstract
OBJECTIVE Osteolysis caused by wear particles is the main reason for joint replacement failure. Inhibition of osteoclast differentiation relieves wear particle-induced osteolysis. Our study aimed to explore the effect of lncRNA maternally expressed gene 3 (MEG3) on osteoclast differentiation and wear particle-induced osteolysis, and to improve the potential mechanism of interleukin-10 (IL-10) inhibition on osteoclast differentiation. METHODS Polymethylmethacrylate (PMMA) -induced osteolysis mice model and receptor activator of nuclear factor-B ligand (RANKL) -induced osteoclast differentiation model were constructed. Tartrate-resistant acidic phosphatase (TRAP) staining, hematoxylin-eosin (HE) staining, immunohistochemical staining, bone resorption assay, dual-luciferase assay, RNA pull-down assay, RNA immunoprecipitation, and chromatin immunoprecipitation were executed. RESULTS MEG3 levels were increased and interferon regulatory factor 8 (IRF8) levels were decreased in PMMA-induced osteolysis mice. IL-10 inhibited RANKL-induced osteoclast differentiation, promoted MEG3 methylation, and inhibited MEG3 expression. Moreover, knockdown of MEG3 inhibited osteoclast differentiation and increased IRF8 levels. Meanwhile, MEG3 combined with signal transducer and activator of transcription 1 (STAT1), STAT1 combined with IRF8, and overexpression of MEG3 inhibited STAT1 binding to IRF8. Further studies have shown that knockdown of MEG3 inhibited osteoclast differentiation and alleviated osteolysis, but knockdown of IRF8 weakened these results. CONCLUSION MEG3 regulated the expression of IRF8 by binding to STAT1, thereby affecting osteoclast differentiation and wear particle-induced osteolysis. IL-10 might inhibit osteoclast differentiation by MEG3/IRF8.

Abstract
BACKGROUND Third-generation total elbow arthroplasties (TEAs) have shown better mechanical characteristics than older designs. However, these results remain purely mechanical and lack clinical evidence. The purpose of this study was to evaluate clinical and radiographic outcomes of the new-generation semiconstrained Nexel TEA performed at our center. MATERIALS AND METHODS Between 2015 and 2017, 9 Nexel TEAs were implanted in 9 patients (mean age 61 years, range 38-71). Indication for further surgery, range of motion, mean Mayo Elbow Performance Score (MEPS), Subjective Elbow Value (SEV), radiolucency lines, outcome measures that included implant survival, complications, and revisions were assessed. RESULTS The mean follow-up was 28 months (5-46 months). Average range of motion significantly improved from pre- to postoperation, with flexion from 120° (70°-140°) to 140° (130°-155°) and supination from 60° (0°-80°) to 80° (80°). Average MEPS improved from 33 (5-45) to 85 points (30-95). During the study period, 5 elbows (56%) experienced complications and 2 (22%) underwent revision. Aseptic humeral loosening was the main indication for revision. The survivorship rate without revision was 75% at 45 months. CONCLUSIONS The short-term clinical results of the Nexel TEA are satisfactory. However, an unusually high rate of complications and revisions was observed, mainly at the humeral component. Further research with longer follow-up and more patients included are needed to validate this new prosthesis.

Abstract
Background Osteomyelitis variolosa is a self-limiting disease triggered by variola virus that cannot be prevented or repaired. Smallpox has been eradicated for 40 years, and complications that remain after smallpox has been cured have become a remarkable diagnostic challenge for contemporary physicians. In this systematic review, we searched PubMed (MEDLINE), Web of Science, and Google Scholar for cases on complications, diagnosis, and treatment for osteomyelitis variolosa between January 1980 and February 2021. Results Ten papers and eleven finished cases, all patients from India, were included for comparison with the present case. In total, 100% of patients presented with bilateral elbow deformities, the ankle was the second most common site of lesion in 50%, and knee lesions accounted for 25% in this study. Flexion contracture, joint instability, secondary arthritis, and fracture are common complications of osteomyelitis variolosa, and most patients receive conservative treatment, while internal fixation has good results for combined fractures. Conclusions Although osteomyelitis variolosa is not a direct threat to the safety of patients, severe skeletal deformities can have a significant impact on quality of life. With advances in surgical techniques, clinicians are offering an increasing number of treatment options for patients with osteomyelitis variolosa. However, most importantly, smallpox has basically been removed from the historical arena, and for areas where smallpox was once endemic, physicians need to deepen the understanding of this disease again.

J Shoulder Elbow Surg 2021; 30:1662-1669. [PMID: 33486063 DOI: 10.1016/j.jse.2020.12.007] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/18/2020] [Revised: 11/27/2020] [Accepted: 12/05/2020] [Indexed: 02/01/2023]
Abstract
BACKGROUND The incidence of total elbow arthroplasty (TEA) is increasing, and an improved understanding of elbow kinematics and biomaterials has driven advances in implant design. In modern practice, cemented, semiconstrained devices are most frequently used. The Discovery TEA has demonstrated promising early results, although there are a paucity of follow-up studies and no dedicated mid- to long-term series. We therefore present the longest, most complete such study to date. METHODS A prospectively maintained local joint registry was interrogated to yield a consecutive series of Discovery TEAs performed at a single non-design center. The minimum follow-up period was set at 5 years. Revision procedures and TEAs performed for acute trauma were excluded. The primary outcome was survivorship of the implant. The secondary outcomes included clinical, radiographic, and patient-reported outcomes. RESULTS We identified 67 TEAs in 58 patients for inclusion at a mean of 98.5 ± 20.4 months from surgery. Four cases (6%) were lost to follow-up, and implant survival was censored accordingly. The implant was revised in 14 cases (20.9%). The Kaplan-Meier method showed an implant survivorship rate of 76.8% at 119 months. A significant difference in survival was found between dominant and nondominant elbows (P = .012, Breslow test), with elbow dominance conferring a 4.5-fold increased risk of revision (relative risk, 4.5; 95% confidence interval, 1.1-18.5). Pooled clinical outcomes (70.9% follow-up at minimum of 60 months and median of 77.8 months) were also determined. CONCLUSIONS We present the longest-term and most complete single-center follow-up study of the Discovery TEA to date. Further long-term survival studies are required to elucidate the performance of this implant compared with more established designs. We have also demonstrated differences in implant survivorship owing to hand dominance for the first time.

Abstract
PURPOSE Total elbow arthroplasty (TEA) can be used, with varying degrees of success, for the treatment of rheumatoid arthritis, osteoarthritis, and distal humerus fractures and their sequelae in elderly patients. Some of the largest studies of TEA have included data from more than 20 years ago and may not reflect the current practice of TEA. We sought to describe a modern cohort of patients who underwent TEA in a United States integrated health care system. METHODS All patients aged 18 years and older who underwent primary unilateral TEA from January 1, 2009, through March 31, 2018, were identified to conduct a descriptive study. The patients' characteristics and demographics, including age, body mass index, sex, diabetes status, American Society of Anesthesiologists classification, and surgical indication, were recorded. The crude cumulative revision probability as well as the 90-day postoperative incidence rate of emergency department visit, readmission, and mortality was calculated. RESULTS A total of 170 patients met our inclusion criteria. The annual procedure volume nearly doubled, from 11 procedures in 2009 to 21 procedures in 2017. The most common indication for TEA was fracture (40.6%), followed by rheumatoid arthritis (36.5%). At 4-year follow up, the crude cumulative revision probability was 9.8% (95% confidence interval, 5.6%-16.9%). Of the 170 patients who underwent TEA, 43 (25.3%) experienced a 90-day emergency department visit, 24 (14.1%) experienced a 90-day readmission, and 2 (1.2%) died within 90 days postoperatively. CONCLUSIONS This cohort of patients who underwent TEA using modern implants showed a notable increase in the volume of TEA over the study period, with more TEAs performed for trauma. The incidence of readmission and emergency department visits following TEA were high in this study. Further studies are needed to better define the current practice of TEA in the community at large.

Abstract
BACKGROUND Revision total elbow arthroplasty (TEA) has increased, especially in young patients with high functional expectations. The objective of this study was to evaluate the long-term results of revision TEA with a single semiconstrained prosthesis. METHODS Thirty-four revision TEAs were performed with a Coonrad/Morrey prosthesis in 32 patients; 2 patients had bilateral procedures. The mean patient age was 61 years (range, 22 to 76 years), and the revision TEA was performed at a mean time of 7.8 years (range, 1.6 to 21 years) after the primary TEA. Etiologies for revisions were humeral and ulnar aseptic loosening (n = 14), ulnar aseptic loosening (n = 8), humeral aseptic loosening (n = 6), septic arthritis (n = 4), and unstable unlinked prostheses (n = 2). Clinical and radiographic evaluations were performed with systematic preoperative infection workup and quantification of bone loss. The mean follow-up was 11.4 years (range, 2 to 21 years). RESULTS The Mayo Elbow Performance Score (MEPS) at the last follow-up was excellent in 6 cases, good in 18 cases, fair in 8 cases, and poor in 2 cases, with a mean improvement (and standard deviation) between the preoperative values at 42.4 ± 16.1 points and the postoperative values at 81.8 ± 12 points (p < 0.001). The mean pain scores improved significantly from 6.7 ± 1.3 points preoperatively to 1.4 ± 1.4 points postoperatively (p < 0.001). The flexion-extension arc increased significantly (p = 0.02) from 74° ± 27° preoperatively to 100° ± 31° postoperatively. The total number of complications was 29 in 19 revision TEAs (56%). Twenty of the 29 complications simply required monitoring without surgical intervention. Six repeat surgical procedures were required, and 3 implant revisions (9%) were performed. CONCLUSIONS Revision TEA with a semiconstrained prosthesis can provide good clinical results that can be maintained during follow-up. The rate of complications is high. Proper evaluation of the risk-benefit ratio is essential for each revision TEA and should be discussed with the patient. LEVEL OF EVIDENCE Therapeutic Level IV.

Abstract
BACKGROUND As the health care system in the United States shifts toward value-based care, there has been increased interest in performing total joint arthroplasty in the outpatient setting to optimize costs, outcomes, and patient satisfaction. Several studies have demonstrated success in performing ambulatory total knee and hip arthroplasty. The purpose of this study was to compare short-term outcomes and complications after total elbow arthroplasty (TEA) across the inpatient and outpatient operative settings. METHODS The American College of Surgeons National Quality Improvement Program database was queried to identify 575 patients undergoing primary TEA using the Current Procedural Terminology code 24363. Of this sample, 458 were inpatient and 117 were outpatient procedures. Propensity score matching using a 3:1 inpatient-to-outpatient ratio was performed to account for baseline differences in several variables-age, sex, body mass index class, American Society of Anesthesiologists class, and various comorbidities-between the inpatient and outpatient groups. After matching, the rates of various short-term outcomes and complications were compared between the inpatient and outpatient groups. RESULTS Inpatient TEA was associated with a higher rate of complications relative to outpatient TEA, including non-home discharge (14.9% vs. 7.5%, P = .05), unplanned hospital readmission (7.4% vs. 0.9%, P = .01), surgical complications (7.6% vs. 2.6%, P = .04), and medical complications (3.6% vs. 0.0%, P = .04). CONCLUSION Outpatient TEA has a lower short-term complication rate than inpatient TEA. Outpatient TEA should be considered for patients for whom such a discharge pathway is feasible. Future research should focus on risk stratification of patients and specific criteria for deciding when to pursue outpatient TEA.

[PMID: 32197768 DOI: 10.1016/j.jse.2019.12.021] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/31/2019] [Revised: 12/06/2019] [Accepted: 12/10/2019] [Indexed: 02/01/2023]
Abstract
BACKGROUND Total elbow arthroplasty has traditionally been used in the treatment of inflammatory arthropathy patients. More and more, however, its use is expanding to include acute trauma and sequelae of trauma. In New Zealand, the most commonly used prosthesis is the Coonrad-Morrey prosthesis, but the Latitude prosthesis has gained in popularity, with a 3-fold increase in implantation over the past 5 years. METHODS Prospectively collected national joint registry data were used to compare the survival rates of these prostheses. Underlying diagnoses, reasons for revision, and patient-reported outcome measures, as well as patient age and exact implants used, were all recorded. Statistical analysis involved survival analysis using Kaplan-Meier curves and the paired Student t test. RESULTS Over the 18-year study interval, the Coonrad-Morrey prosthesis has shown consistently lower revision rates than the Latitude prosthesis. This was true for both the linked and unlinked Latitude prostheses and was not affected by radial head replacement or underlying diagnosis. In all cases, the risk of revision for the Coonrad-Morrey prosthesis was reduced by at least 65% compared with the Latitude prosthesis. CONCLUSION This study using New Zealand Joint Registry data shows a lower failure rate of the Coonrad-Morrey elbow prosthesis compared with the Latitude prosthesis. The hazard ratio for a revision procedure for the Coonrad-Morrey prosthesis compared with the Latitude prosthesis was 0.28 (95% confidence interval, 0.14-0.55). This lower rate was evident irrespective of linkage and radial head replacement. The reason for the lower rate of revision with the Coonrad-Morrey prosthesis is likely multifactorial, but perhaps when used by lower-volume surgeons, the Coonrad-Morrey prosthesis may confer better implant longevity.
