RESUMO
BACKGROUND: Postoperative infection, aseptic loosening, and perioperative medical complications after total ankle arthroplasty (TAA) are all devastating problems. While previous studies have shown diabetes as a risk factor predisposing patients to postoperative complications, not all literature supports this association following TAA. The goal of this study is to determine if diabetes influences midterm outcomes following TAA. METHODS: An insurance database was utilized to identify patients undergoing TAA for ankle arthritis with a concurrent diagnosis of diabetes based on Current Procedural Terminology (CPT) and International Classification of Diseases, Ninth Revision (ICD-9) and Tenth Revision (ICD-10), diagnosis and procedure codes from 2010 to 2021. The postoperative outcomes of all-cause revision, periprosthetic joint infection (PJI), septic revision, and aseptic revision were compared between patients with and without diabetes with a minimum 2-year follow-up using Kaplan-Meier and multivariate Cox proportional hazards analyses. Patient demographics, comorbidities, and Charlson Comorbidity Index were analyzed via univariate and multivariate analysis. RESULTS: The study population included 8317 patients, 345 (4.1%) of whom had a concurrent diabetes diagnosis, who underwent TAA. After multivariate Cox proportional hazards analysis, the 5-year cumulative incidence of being coded as having PJI was 7.3% in patients with known diabetes compared to 3.9% in patients without known diabetes, with a 95% increased risk (hazard ratio [HR] 1.95, 95% CI 1.15-3.30, P = .01). Patients with diabetes also demonstrated a 5-year cumulative incidence of septic revision of 1.4% compared to 0.4% in those without, with a 363% increased risk (HR 4.63, 95% CI 1.22-17.52, P = .02). However, there was no difference in the 5-year cumulative incidence of all-cause revision TAA with 4.6% in patients with diabetes and 4.3% in those without (HR 1.29, 95% CI 0.69-2.44, P = .42). CONCLUSION: In this database, the 5-year risk of PJI and septic revision was higher among patients with diabetes compared to those without, but cumulative incidence of all-cause revision TAA was not different between groups. LEVEL OF EVIDENCE: Level III, retrospective cohort database study.
RESUMO
BACKGROUND: The metabolic abnormalities that occur secondary to chronic kidney disease (CKD) increase the risk of femoral neck fractures compared to the general population. The purpose of this study is to determine whether impaired renal function is an independent risk factor for complications after surgery for femoral neck fracture. METHODS: The ACS-NSQIP database was reviewed for patients who underwent total hip arthroplasty, hemiarthroplasty and open reduction internal fixation (ORIF) for femoral neck fractures between 2007 and 2018. Patients were split into cohorts based on calculated estimated glomerular filtration rate. Demographic information, comorbidities, and 30-day complications were analysed with univariate and multivariate analyses using chi-square, Fischer's exact and analysis of variance testing. RESULTS: The total number of patients for the study was 163,717. Patients with CKD stage 4 and 5 had an increased rate of any complication (39.1 and 36.7% respectively) compared with higher eGFRs (p < 0.001). Similarly, 30-day mortality was increased at 6.0% and 6.7% for both stage 4 and 5 (p < 0.001). By multivariate regression, those with CKD Stage 4 and 5 were at increased risk for any complication compared to patients with a normal preoperative eGFR of 90-120 (p < 0.001). CONCLUSIONS: This study demonstrated that patients with CKD Stage 4 and 5 are at increased risks of all complications, including death, renal, pulmonary and thromboembolic disease. Therefore, these patients should be cared for from a multidisciplinary approach with close attention to postoperative medications and fall prevention to help mitigate the risk of complications in the immediate postoperative period.

BACKGROUND: Search engines generate lists of the most relevant websites using a keyword or phrase query and are integral in guiding consumer preferences. Digital information is important in the field of medicine, influencing what patients learn about their conditions and who they choose as providers. When two types of healthcare providers, such as podiatry and foot and ankle orthopaedic surgeons (FAOSs), share an overlapping consumer market, whichever group has a larger digital footprint receives increased digital engagement. METHODS: The Google search engine was used to query nine common foot and ankle-associated terms using a "search term + zip code" format for 150 zip codes divided into urban, suburban, and rural population densities. The first 10 results of each search were classified into one of five categories. Site content was classified as podiatry-oriented, other MD/DO-oriented, or FAOS-oriented. Separately, a ratio between podiatrists and FAOSs was calculated for each population density group. Data were then normalized using this ratio and reanalyzed with the Wilcoxon signed-rank test with significance at P < 0.05. RESULTS: Of 13,500 total search results, 4,992 (36.9%) were podiatry-oriented, 2,109 (15.6%) were other MD/DO-oriented, and 436 (3.2%) were FAOS-oriented. All geographic areas featured a higher number of podiatry than FAOS-oriented sites. FAOSs have more results per provider in urban areas (P < 0.001), although podiatrists had more in suburban and rural areas (P < 0.001, P < 0.001). Podiatrists have greater digital engagement in descriptive search terms. "Ankle replacement" has greater FAOS engagement in all three geographic areas. DISCUSSION: Foot and ankle-related Internet search terms results are overwhelmingly composed of podiatry-oriented sites. Per provider, regional differences are demonstrated, with FAOS having more sites in urban areas only. FAOS scope-of-practice terms such as "ankle replacement" still retain greater engagement by FAOSs. Search engine optimization and saturation strategies should be considered. LEVEL OF EVIDENCE: Level 3 (observational study).

Background: Total ankle arthroplasty (TAA) is performed for ankle arthritis and there has been interest investigating which anesthetic method is the best choice in order to optimize perioperative outcomes. In this study, we compared postoperative complications after TAA for patients receiving either 1) general anesthesia alone or 2) general anesthesia plus regional anesthesia. Methods: Patients undergoing primary TAA from 2007 to 2018 were identified in a national database. Patients were stratified into 2 cohorts: general anesthesia and general anesthesia combined with regional anesthesia. In this analysis, 30-day wound, cardiac, pulmonary, renal, thromboembolic, and sepsis complications, as well mortality, postoperative transfusion, urinary tract infection, extended length of stay, and reoperation were assessed. Bivariate analyses and multivariable logistical regression were performed. Results: Of 1,084 total patients undergoing TAA, 878 patients (81.0%) had general anesthesia and 206 (19.0%) had general anesthesia combined with regional anesthesia. Following adjustment, there were no increased risk of postoperative complications in the combined general and regional anesthesia group compared to those who only underwent general anesthesia. Conclusion: Compared to general anesthesia alone, the addition of regional anesthesia to general anesthesia for TAA is not associated with increased risk of complications in the perioperative period. Level of Evidence: III.

PURPOSE: To compare the rates of reoperation and 90-day perioperative complications between open arthrotomy and arthroscopy for the treatment of septic ankle arthritis using a national all-payer claims database. METHODS: Patients with a diagnosis of septic ankle arthritis who underwent irrigation and debridement through arthroscopy or arthrotomy were identified in a national data set from 2015-2020 through an all-payer claims database. Demographic and comorbidity characteristics including age, sex, infectious etiologies, and Elixhauser comorbidities were obtained. The rate of reoperation, defined as a proxy for failure of initial intervention, was the primary outcome. Secondary outcomes including readmissions, surgical-site infections, amputations, wound complications, and 90-day medical complications were compared between the 2 cohorts. RESULTS: In total, 168 patients undergoing arthroscopy and 794 patients undergoing arthrotomy for septic ankle arthritis were identified. There were no significant differences in reoperation rates between patients who underwent open arthrotomy and those who underwent arthroscopy (P = .997). However, the rates of surgical-site infection (P = .014) and hospital readmission (P < .001) were significantly higher in the open arthrotomy cohort compared with the arthroscopy cohort. CONCLUSIONS: Although there was no significant difference in reoperation rates between arthroscopic and open irrigation and debridement for the treatment of septic ankle arthritis, this study showed significantly higher odds of surgical-site infection and hospital readmission in patients who underwent open arthrotomy when compared with arthroscopy. Case-specific patient and technical considerations should guide the surgical decision-making process to limit secondary complications because this study exemplifies similar reoperation rates between the 2 surgical modalities. LEVEL OF EVIDENCE: Level III, nonrandomized cohort analysis.

BACKGROUND: The COVID-19 pandemic has had far-reaching effects on healthcare systems and society with resultant impact on trauma systems worldwide. This study evaluates the impact the pandemic has had in the Washington, DC Metropolitan Region as compared with similar months in 2019. DESIGN: A retrospective multicenter study of all adult trauma centers in the Washington, DC region was conducted using trauma registry data between January 1, 2019 and May 31, 2020. March 1, 2020 through May 31, 2020 was defined as COVID-19, and January 1, 2019 through February 28, 2020 was defined as pre-COVID-19. Variables examined include number of trauma contacts, trauma admissions, mechanism of injury, Injury Severity Score, trauma center location (urban vs. suburban), and patient demographics. RESULTS: There was a 22.4% decrease in the overall incidence of trauma during COVID-19 compared with a 3.4% increase in trauma during pre-COVID-19. Blunt mechanism of injury decreased significantly during COVID-19 (77.4% vs. 84.9%, p<0.001). There was no change in the specific mechanisms of fall from standing, blunt assault, and motor vehicle crash. The proportion of trauma evaluations for penetrating trauma increased significantly during COVID-19 (22.6% vs. 15.1%, p<0.001). Firearm-related and stabbing injury mechanisms both increased significantly during COVID-19 (11.8% vs. 6.8%, p<0.001; 9.2%, 6.9%, p=0.002, respectively). CONCLUSIONS AND RELEVANCE: The overall incidence of trauma has decreased since the arrival of COVID-19. However, there has been a significant rise in penetrating trauma. Preparation for future pandemic response should include planning for an increase in trauma center resource utilization from penetrating trauma. LEVEL OF EVIDENCE: Epidemiological, level III.
RESUMO
INTRODUCTION: Revision total hip arthroplasty (rTHA) is increasingly performed but may carry a high rate of complication. This aim of the study was to determine if a decreased eGFR increases risks of postoperative complications following rTHA. METHODS: A retrospective cohort study using the American College of Surgeons National Quality Improvement Program Database was conducted. Patients undergoing rTHA between 2007 and 2014 were identified and stratified by glomerular filtration rates (eGFR): eGFR > 125 mL/min, eGFR 90-125 mL/min, eGFR 60-90 mL/min, eGFR 30-60 mL/min, and eGFR < 30 mL/min. The incidence of postoperative adverse events within 30 days, including cardiac, pulmonary, renal, septic, thromboembolic, urinary tract, and wound complications, blood transfusion, death, length of stay > 7 days, and unplanned return to the operating room, was assessed. The complication rates following rTHA were assessed with univariate and multivariate analysis with a significance set at p < 0.05. RESULTS: In total, 8898 revision THA procedures were included for analysis. 28.4% of patients that underwent rTHA developed a complication following surgery. Following adjustment, an eGFR of less than 30 mL/min independently increased the odds of any complication (OR 1.447; 95% C.I. 1.010-2.074; p = 0.044), cardiac complications (OR 3.344; 95% C.I. 1.040-10.752; p = 0.043), blood transfusion (O.R. 1.623; 95% C.I. 1.122-2.352; p = 0.010), and extended length of stay (O.R. 2.392; 95% C.I. 1.526-3.759; p < 0.001) when compared to normal renal function. CONCLUSIONS: Diminished eGFR of less than 30 mL/min increased the odds of total complications, cardiac complications, blood transfusions, and extended length of stay compared to normal renal function.

Femoral neck fractures after total hip resurfacing procedures occur infrequently but require immediate orthopedic intervention. Historically, they have been treated by conversion to traditional total hip arthroplasty. However, to the authors' knowledge, no treatment algorithm has ever been described. The authors have directly treated or consulted on 13 cases of periprosthetic femoral neck fractures after metal-on-metal hip resurfacing arthroplasties that were successfully treated nonoperatively: all fractures healed with protected weight bearing, producing excellent clinical results. Two cases are described in detail, and the authors propose a classification system that can assist the orthopedist in choosing the treatment regimen. Type I fractures are nondisplaced and should be initially treated nonoperatively with a course of protected weight bearing. If successful, the overall success of the resurfacing should not be compromised. Partially displaced, or type II, fractures may heal with nonoperative management. However, if the components have shifted, it may affect the long-term durability of the arthroplasty and eventually result in premature conversion to a traditional total hip replacement. Depending on the position of the components, it may also have an effect on the ion generation potential of the metal-on-metal articulation. This treatment pathway can be undertaken only with a full and detailed explanation of all of the possible complications and outcomes with the patient. Completely displaced, or type III, fractures require immediate conversion to total hip arthroplasty.

Acute hematogenous septic arthritis caused by the genus Klebsiella is extremely rare. This case report describes a prosthetic joint infected with Klebsiella pneumoniae via acute hematogenous spread. This is the first reported case of K pneumoniae pyogenic arthritis with a coexisting occult colonic adenocarcinoma. The patient was treated successfully with open irrigation, debridement, polyethylene spacer exchange, and chronic suppressive antibiotics. The underlying colon cancer was recognized early, and the patient responded well to surgery and adjuvant chemotherapy. This case illustrates the importance of having a high index of suspicion for underlying pathologic processes when an unusual organism presents as the cause of septic arthritis.

BACKGROUND: We hypothesized that a locking plate would be stronger than a blade plate for tibiotalocalcaneal arthrodesis under dorsiflexion and torsional loading. MATERIALS AND METHODS: Nine pairs of matched cadaveric lower extremities were used. BMD was obtained for each specimen. Each received a retrograde augmentation screw and a stainless steel LC-angled blade plate (Synthes, Paoli, PA) or a stainless steel LCP proximal humerus locking plate (Synthes, Paoli, PA). Specimens were cyclically loaded in dorsiflexion to simulate 6 weeks of partial weightbearing and then monotonically loaded to failure. Specimens were removed from the load frame and remounted to simulate fusion. The specimen received an axial load of 720 N and was externally rotated proximal to the construct at 5 degrees/sec to fracture. Data were compared with a Student's t-test. Pearson correlation analysis was used to determine whether bone mineral density was significantly related to measured parameters. Significance was set at p < or = 0.05. RESULTS: The locking plate group had higher initial stiffness, higher dorsiflexion and torsional load to failure, and lower construct deformation than the blade plate group. Bone mineral density was positively correlated with dorsiflexion failure load and torsional failure load in the locking plate construct. CONCLUSION: Fixation with the locking plate was superior to that with the blade plate. CLINICAL RELEVANCE: Use of a locking plate may be an effective fixation technique in tibiotalocalcaneal arthrodesis, especially in complex hindfoot reconstructions with bone loss or deformity.
