- Introduction:Female surgeons remain a minority within the field of orthopaedics, particularly in certain specialties such as arthroplasty. There is no scientific evidence on whether the surgeon's sex affects the patient-reported outcome after orthopaedic surgery such as total hip arthroplasty (THA). We therefore aimed to investigate the association between surgeon sex and health-related quality of life after THA.Methods:Data on primary THAs performed between 2008 and 2016 were collected from 10 hospitals in western Sweden. The data were linked with the Swedish Hip Arthroplasty Register, a regional patient register and the National Board of Health and Welfare, resulting in a data set that included surgeon-related and patient-related data. The outcome of the study was the change in health-related quality of life, measured with the 3-level version of EQ-5D (EQ-5D-3L) Index and EQ-visual analog scale (VAS), before and 1-year after THA. Mixed models, using hierarchical linear regression adjusted for patient sex, age, preoperative health-related quality of life and Charnley classification, were fitted to estimate the gain in EQ-5D-3L Index and EQ-VAS with 95% confidence intervals based on surgeon sex.Results:In total, 8,383 primary THAs were done for osteoarthritis by 193 surgeons. Of those, 37 were women and 156 were men. The regression model was showed that patients operated by female surgeons had a beta-coefficient of gain in EQ-5D-3L Index of -0.001 (-0.022 to 0.021) and a beta-coefficient of gain in EQ VAS of 0.004 (-0.023 to 0.030), compared with patients operated by male surgeons. Similar results were obtained in a sensitivity analysis including attendings only.Discussion:Patients undergoing primary THA reported similar gain in health-related quality of life regardless of surgeon sex. Based on our results, health-related quality of life after primary THA was not associated with the sex of the operating surgeon.

- Background: Stereotypes may prevail, but little is known about the influence that the sex of an orthopaedic surgeon may have on outcomes. In a recently published study, there were no differences in the rate of adverse events following total hip arthroplasties (THAs) performed by female or male orthopaedic surgeons. The objective of the present study was to investigate whether there was any difference in adverse events within 90 days following a primary THA performed by either a male or female surgeon in Sweden. Methods: A retrospective study was performed to evaluate primary THAs performed for osteoarthritis between 2008 and 2016 at 10 hospitals in western Sweden. Local hospital data were linked with the Swedish Hip Arthroplasty Register (SHAR) and with a regional patient register. Data collected from local hospitals and the SHAR included surgeon-related information (e.g., sex, annual volume, and level of training) and patient-related information (e.g., age, sex, and Elixhauser comorbidity index). Adverse events were retrieved from the regional patient register. The definition of adverse events followed the SHAR definition of adverse events. Mixed models were used to investigate the impact of surgeon sex on adverse events. Results: A total of 11,993 primary THAs were performed by 200 surgeons, of whom 17.5% were women. The proportions of adverse events within 90 days were similar for female (6%) and male (7%) surgeons. No association was found between surgeon sex and adverse events (adjusted odds ratio, 0.72; 95% confidence interval, 0.52 to 1.00) when all surgeons (both attendings and residents) were included in the analysis. A sensitivity analysis that included attendings only yielded similar results (adjusted odds ratio, 0.88; 95% confidence interval, 0.60 to 1.29). Conclusions: Despite a small tendency toward lower rates of adverse events at 90 days after THAs performed by female surgeons, there was no significant association between surgeon sex and the risk of adverse events following THA.

- Background:The optimal treatment of displaced femoral neck fractures in patients 55 to 70 years old remains controversial. The aim of the present study was to assess the effect of closed reduction and internal fixation with cannulated screws (IF) compared with total hip arthroplasty (THA) on hip pain and function, with use of data for outcome measures, complications, and reoperations.Methods:This multicenter randomized controlled trial included all patients 55 to 70 years old who presented with a low-energy displaced femoral neck fracture between December 2013 and December 2018. Patients were randomly allocated to undergo either IF or THA. The primary outcome was the Harris Hip Score (HHS) at 12 months postoperatively. Secondary outcomes were the HHS at 4 and 24 months postoperatively, Oxford Hip Score (OHS), Hip Disability and Osteoarthritis Outcome Score (HOOS), health-related quality of life (EQ-5D-3L [EuroQol 5 Dimensions 3 Levels] index score and EQ-VAS [visual analogue scale]), VAS for pain, and VAS for patient satisfaction at 4, 12, and 24 months postoperatively. Complications and reoperations were continuously monitored. The primary analyses were performed according to the intention-to-treat principle.Results:A total of 102 patients with a mean (± standard deviation) age of 63.7 ± 4.2 years were allocated to IF (n = 51) or THA (n = 51). The mean difference in the primary outcome, the HHS at 12 months postoperatively (5.3; 95% confidence interval, 0.9 to 9.7; p = 0.017), was below the predefined minimal clinically important difference of 10 points. However, patients who underwent THA had a significantly higher HHS at 4 and 12 months, better OHS at 4 and 12 months, and better HOOS at 4, 12, and 24 months postoperatively. Patients who underwent THA also reported better health-related quality of life at 4 months postoperatively and reported greater satisfaction and less pain at 4 and 12 months postoperatively. A total of 26 patients in the IF group (51%; 95% confidence interval, 37% to 65%) and 2 patients in the THA group (4%; 95% confidence interval, 0.5% to 13%) underwent a major reoperation.Conclusions:In this randomized controlled trial, we showed that patients between 55 and 70 years old who underwent THA for a low-energy displaced femoral neck fracture experienced better outcomes than those who underwent closed reduction and internal fixation.Level of Evidence:Therapeutic Level I.

- Aims Our aim was to examine the Elixhauser and Charlson comorbidity indices, based on administrative data available before surgery, and to establish their predictive value for mortality for patients who underwent hip arthroplasty in the management of a femoral neck fracture. We analyzed data from 42 354 patients from the Swedish Hip Arthroplasty Register between 2005 and 2012. Only the first operated hip was included for patients with bilateral arthroplasty. We obtained comorbidity data by linkage from the Swedish National Patient Register, as well as death dates from the national population register. We used univariable Cox regression models to predict mortality based on the comorbidity indices, as well as multivariable regression with age and gender. Predictive power was evaluated by a concordance index, ranging from 0.5 to 1 (with the higher value being the better predictive power). A concordance index less than 0.7 was considered poor. We used bootstrapping for internal validation of the results. The predictive power of mortality was poor for both the Elixhauser and Charlson comorbidity indices (concordance indices less than 0.7). The Charlson Comorbidity Index was superior to Elixhauser, and a model with age and gender was superior to both indices. Preoperative comorbidity from administrative data did not predict mortality for patients with a hip fracture treated by arthroplasty. This was true even if association on group level existed.

- Aims The aim of this study was to investigate the potentially increased risk of dislocation in patients with neurological disease who sustain a femoral neck fracture, as it is unclear whether they should undergo total hip arthroplasty (THA) or hemiarthroplasty (HA). A secondary aim was to investgate whether dual-mobility components confer a reduced risk of dislocation in these patients. Methods We undertook a longitudinal cohort study linking the Swedish Hip Arthroplasty Register with the National Patient Register, including patients with a neurological disease presenting with a femoral neck fracture and treated with HA, a conventional THA (cTHA) with femoral head size of <= 32 mm, or a dual-mobility component THA (DMC-THA) between 2005 and 2014. The dislocation rate at one- and three-year revision, reoperation, and mortality rates were recorded. Cox multivariate regression models were fitted to calculate adjusted hazard ratios (HRs). Results A total of 9,638 patients with a neurological disease who also underwent unilateral arthroplasty for a femoral neck fracture were included in the study. The one-year dislocation rate was 3.7% after HA, 8.8% after cTHA < 32 mm), 5.9% after cTHA (= 32 mm), and 2.7% after DMC-THA. A higher risk of dislocation was associated with cTHA (< 32 mm) compared with HA (HR 1.90 (95% confidence interval (CI) 1.26 to 2.86); p = 0.002). There was no difference in the risk of dislocation with DMC-THA (HR 0.68 (95% CI 0.26 to 1.84); p = 0.451) or cTHA (= 32 mm) (HR 1.54 (95% CI 0.94 to 2.51); p = 0.083). There were no differences in the rate of reoperation and revision-free survival between the different types of prosthesis and sizes of femoral head. Conclusion Patients with a neurological disease who sustain a femoral neck fracture have similar rates of dislocation after undergoing HA or DMC-THA. Most patients with a neurological disease are not eligible for THA and should thus undergo HA, whereas those eligible for THA could benefit from a DMC-THA.
