Strategies to improve end-of-life decision-making and palliative care following hip fracture in frail older adults: a scoping review.

BACKGROUND: Although surgery is the gold standard following a hip fracture, the potential for rehabilitation and survival rates are low in frail older patients. Some patients may derive more benefit from palliative care. The objectives of this review were to identify the available strategies to improve end-of-life decision-making and palliative care for frail patients with hip fractures and to synthetise their level of support. METHODS: We conducted a scoping review of the scientific and grey literature, searching seven databases and websites of associations. We included all study designs, expert opinion articles and clinical practice guidelines (CPGs). Data were synthetised according to the Approach to Patient with Limited Life Expectancy and Hip Fracture framework. The number of research items and their level of evidence were tabulated for each of the recommended strategies. RESULTS: Of the 10 591 items identified, 34 were eligible. The majority of included articles were original research studies (n = 15). Half of the articles and CPGs focused on intervention categories (55%) such as goals of care discussion and comfort care, followed by factors to consider in the end-of-life decision-making process (25%) and prognosis assessments (20%), mainly through the estimation of life expectancy. The level of evidence for these strategies remains low, given the limited number of prospective studies supporting them. CONCLUSIONS: This scoping review highlighted that end-of-life care in frail older patients with a hip fracture remains understudied. The strategies identified could be prioritised for future research to improve the well-being of the target population while promoting sustainable resource management.

Palliative care is a viable option for frail elderly patients with neurocognitive disorders admitted for hip fractures.

IMPORTANCE: Most patients presenting with a hip fracture regardless of their comorbidities are surgically treated. A growing body of research states that a certain type of elderly patient could benefit more from a palliative approach. OBJECTIVE: Identify the patient who would benefit most from a palliative care approach instead of a surgery. DESIGN: Exploratory-matched retrospective cohort study between 2015 and 2021. SETTING: Single Level 1 Trauma Center. PARTICIPANTS: There were 2240 hip fracture patients admitted to our institution between 2015 and 2021. Patients over 65 years old with intertrochanteric or femoral neck fractures could be included. A total of 129 patients opted for palliative care (Palliative Group = PG). This cohort was compared to a matched cohort (for age, sex and fracture type) who underwent surgery but died within three months of the procedure (Surgery Deceased Group = SDG) and another matched cohort who survived more than three months (Surgery Alive Group = SAG) following surgery. MAIN OUTCOMES AND MEASURES: Medical charts were reviewed for patient demographics, autonomy level, level of care, neurocognitive disorders (NCD), fracture type, in-hospital data and outpatient death within three months of admission. Analysis was performed through univariate and multivariate models with SAS OnDemand for Academics (alpha 0.05). RESULTS: Patients in the PG (n = 129) were 88.2 ± 7.2 years old, 71.3% were females, and 61.2% had a femoral neck fracture. Patients in the SDG (n = 95) and SAG (n = 107) were well matched. The PG differed from the SDG (n = 95) and SAG (n = 107) regarding NCD (85.3% vs. 57.9% vs. 36.4%, p < 0.01) and the presence of Behavioral and psychological symptoms of dementia (BPSD) (19.4% vs. 5.3% vs. 3.7%, p < 0.01). There were more known heart failure (24.2% vs. 16.3%, p < 0.01) and Chronic Obstructive Pulmonary Disease (COPD) in the SDG group than in the PG group (26.6 vs. 14.7%, p = 0.02). Patients in the SAG have a significant lower rate of NCD (OR 2,7 (95%CI 1,5-5,0)), heart failure (OR 5,7 (95%CI 1,9-16,4)) and COPD (OR 2,8 (95%CI 1,2-6,3)) than other groups. Prefracture mobility, autonomy and living situation significantly differed between the groups. Median survival was six days in PG and 17 days in SDG. All groups lost autonomy and mobility. There were more complications in the SDG group than in the PG group. The end-of-care trajectory was death or hospice for most patients in the PG and SDG groups. More than 30% of the SAG group could not return home at discharge. CONCLUSION: The presence of an NCD and diminished prefracture autonomy strongly support counseling for palliative care. The high rate of complications when surgery is proposed for frail patients with multiple comorbidities suggests that the concept of palliative surgery needs to be revisited.

Sleep Apnea is Not an Obstacle for Outpatient Hip and Knee Arthroplasty.

BACKGROUND: Up to 25% of patients requiring hip or knee arthroplasty have sleep apnea (SA), and these patients have historically been excluded from outpatient programs. The objectives of this study were to evaluate same-day discharge failure as well as 30-day complications, readmissions, and unexpected visits. METHODS: A retrospective case-control study comparing patients who have and do not have SA matched for age, sex and arthroplasty type (total hip arthroplasty, total knee arthroplasty, unicompartimental knee arthroplasty) who underwent primary outpatient surgery between February 2019 and December 2022 in 2 academic hospitals was conducted. Cases with mild SA, moderate SA with a body mass index (BMI) <35, and SA of all severity treated by continuous positive airway pressure machines were eligible. There were 156 patients included (78 cases). Complications were assessed according to the Clavien-Dindo Classification and the Comprehensive Complication Index. Continuous variables were evaluated by Student's T or Mann-Whitney tests, while categorical data were analyzed by Chi-square or Fisher tests. Univariate analyses were performed to determine discharge failure risk factors. RESULTS: There were 6 cases (7.7%) and 5 controls (6.4%) who failed to be discharged on surgery day (P = .754), with postoperative hypoxemia (6, [3.8%]) and apnea periods (3, [1.9%]) being the most common causes. Higher BMI (odds ratio = 1.19, P = .013) and general anesthesia (odds ratio = 11.97, P = .004) were found to be risk factors for discharge failure. No difference was observed on 30-day readmissions (P = .497), unexpected visits (P = 1.000), and complications on the Clavien-Dindo Classification (P > .269) and Comprehensive Complication Index (P > .334) scales. CONCLUSIONS: Selected patients who have SA can safely undergo outpatient hip or knee arthroplasty. Higher BMI and general anesthesia increased the odds of same-day discharge failure. LEVEL OF EVIDENCE: Level III, Case-control Study.

The POSI study: gender differences in 94 cases of postoperative shoulder surgery infection: results of a 7-year retrospective multicenter study.

BACKGROUND: Contrary to lower limb infection, POstoperative Shoulder surgery Infection (POSI) often involves Cutibacterium acnes. Our aim was to describe patient characteristics and pathogens retrieved in POSI to guide initial empiric antibiotic selection with suspected infection during revision. We also compared microorganisms in infection following trauma, arthroplasty (AP), and arthroscopy (AS). METHODS: A multicenter retrospective study from 2010 to 2016 reviewed laboratory databases and medical records to identify patients with a previous shoulder surgery and a confirmed shoulder infection. The following procedures were included: AP, AS, fracture fixation (FF), and another open surgery (OS). A confirmed shoulder infection was defined as 2 positive cultures or more of the same microorganism, or clear clinical infection with 1 positive culture or more. RESULTS: Among the 5 hospitals and 28 surgeons involved, 94 POSI cases were identified. Mean age was 59 years at index surgery (range: 22-91) with a majority of men (n = 70, 74%). Among POSI cases, AP was the most common index surgery (n = 41), followed by FF (n = 27), AS (n = 16), and OS (n = 10). The median time between index surgery and the first positive sample was 5 months and the mean was 23 months (minimum 6 days to maximum 27 years), illustrating a positively skewed distribution. Cutibacterium spp were identified in 64 patients (68%), including 59 C acnes patients (63%), which was the most frequent germ in all 4 surgical groups. In 86% of cases, C acnes was identified at the first revision. The other 2 most common germs were Staphylococcus epidermidis and Staphylococcus aureus, with 29% and 17%, respectively. Polymicrobial infection was present in 30% of patients. Gender analysis revealed that C acnes was twice as frequent in men (male = 52 of 70, female = 7 of 24; P < .001). S epidermidis was more prevalent in women (n = 11; 46%) compared with men (n = 16; 21%) (P = .032). C acnes infection was most frequent in arthroscopic surgery (n = 14; 70%, P = .049). S epidermidis was 3 times more prevalent in chronic than in acute cases. CONCLUSION: Empiric antimicrobial therapy following POSI, while waiting for culture results, should cover C acnes, S epidermidis, and S aureus. There is a significant gender difference regarding POSI culture results. C acnes is more frequent in men, but should still be covered in women as it was found in 29% of cases.

The impact of Canadian-produced research on the global orthopedic literature: a bibliometric analysis.

BACKGROUND: Little is known about the quality and impact of Canadian-produced research relative to that of other developed nations. The purpose of this study was to determine the contribution of Canadian authors to the orthopedic literature globally and nationally as well as Canada's research productivity in orthopedics. We hypothesized that Canada ranks among the most impactful countries in terms of orthopedic research productivity. METHODS: We performed a bibliometric analysis to identify articles published between 2001 and 2020 in the category of orthopedics. We identified Canada's global rank in terms of overall productivity and assessed the contributions of individual Canadian authors. We also examined the quality of publications as determined by category normalized citation impact (CNCI) and publication in the top quartile of journals (%Q1) in terms of impact factor. In addition, we calculated the percentage of Canadian publications that were in orthopedics. RESULTS: We identified 10 821 orthopedic publications from 2001 to 2020. Canada placed sixth globally in terms of productivity in orthopedic research. The annual productivity of Canadian orthopedic researchers increased over the study period by a factor of 3.2. In terms of research quality, with a %Q1 of 36.5% and a CNCI of 1.22, Canada outperformed Asian countries and the United States; the latter country had a %Q1 of 35.3% and a CNCI of 1.14 over the study period. CONCLUSION: The body of Canadian orthopedic literature has grown consistently over the past 20 years. Despite the overall leadership of the United States and other developed nations such as China and Japan, Canada ranks among the most influential countries in terms of the quality and quantity of orthopedic research.

Should We Use Bipolar Hemiarthroplasty in Patients ≥70 Years Old With a Femoral Neck Fracture? A Review of Literature and Meta-Analysis of Randomized Controlled Trials.

BACKGROUND: Bipolar (BHA) and unipolar hemiarthroplasties (UHA) are interchangeably used in elderly patients with a displaced femoral neck fracture. We ask if there is a difference between BHA and UHA with regards to hip function, in elderly patients. METHODS: Systematic review and meta-analysis was conducted of randomized controlled trials comparing BHA to UHA. The primary outcome was postoperative hip function scores. Secondary outcomes were overall health-related quality of life patient-reported outcomes, acetabular erosion, and postoperative complications. Data sources, last searched on June 1, 2020, were MEDLINE, EMBASE, Cochrane Library, and Web of Science. RESULTS: Fourteen randomized controlled trials were eligible for meta-analysis. There was no difference in hip function scores between BHA and UHA (standardized mean difference 0.32, 95% confidence interval [CI] -0.06 to 0.71, n = 1084, I2 = 87%). Patients with BHA with more than 2-year follow-up had better hip function scores (standardized mean difference 0.68, 95% CI 0.18-1.18, n = 700, I2 = 87%). There was no difference in European Quality of life- five dimensions scores with BHA (mean difference 0.08, 95% CI -0.01 to 0.17, n = 967, I2 = 82%). The use of BHA decreased the risk of acetabular erosion (relative risk 0.38, 95% CI 0.17-0.83, n = 1239, I2 = 0%). There was no difference for revision, mortality, infection, and dislocation (I2 = 0%). CONCLUSION: There seems to be no difference between BHA and UHA with regards to hip function at 2 years. BHA might decrease the risk of acetabular erosion. There is a need for a large randomized controlled trial with a follow-up >2 years and better measurement tools to assess clinical benefits. LEVEL OF EVIDENCE: II.

Aspirin or Rivaroxaban for VTE Prophylaxis after Hip or Knee Arthroplasty.

BACKGROUND: Clinical trials and meta-analyses have suggested that aspirin may be effective for the prevention of venous thromboembolism (proximal deep-vein thrombosis or pulmonary embolism) after total hip or total knee arthroplasty, but comparisons with direct oral anticoagulants are lacking for prophylaxis beyond hospital discharge. METHODS: We performed a multicenter, double-blind, randomized, controlled trial involving patients who were undergoing total hip or knee arthroplasty. All the patients received once-daily oral rivaroxaban (10 mg) until postoperative day 5 and then were randomly assigned to continue rivaroxaban or switch to aspirin (81 mg daily) for an additional 9 days after total knee arthroplasty or for 30 days after total hip arthroplasty. Patients were followed for 90 days for symptomatic venous thromboembolism (the primary effectiveness outcome) and bleeding complications, including major or clinically relevant nonmajor bleeding (the primary safety outcome). RESULTS: A total of 3424 patients (1804 undergoing total hip arthroplasty and 1620 undergoing total knee arthroplasty) were enrolled in the trial. Venous thromboembolism occurred in 11 of 1707 patients (0.64%) in the aspirin group and in 12 of 1717 patients (0.70%) in the rivaroxaban group (difference, 0.06 percentage points; 95% confidence interval [CI], -0.55 to 0.66; P<0.001 for noninferiority and P=0.84 for superiority). Major bleeding complications occurred in 8 patients (0.47%) in the aspirin group and in 5 (0.29%) in the rivaroxaban group (difference, 0.18 percentage points; 95% CI, -0.65 to 0.29; P=0.42). Clinically important bleeding occurred in 22 patients (1.29%) in the aspirin group and in 17 (0.99%) in the rivaroxaban group (difference, 0.30 percentage points; 95% CI, -1.07 to 0.47; P=0.43). CONCLUSIONS: Among patients who received 5 days of rivaroxaban prophylaxis after total hip or total knee arthroplasty, extended prophylaxis with aspirin was not significantly different from rivaroxaban in the prevention of symptomatic venous thromboembolism.

Electromyographic and kinematic study of reverse total shoulder arthroplasty: an observational prospective cohort study.

BACKGROUND: Reverse total shoulder arthroplasty (RTSA) procedures have significantly increased in the last decade as an alternative to the current treatments for cuff-tear arthropathy. Since Grammont's theory in 1987, few data about the in vivo kinetics of the shoulder-girdle musculature in patients with RTSA have been available. The goals of this study are to (1) describe the contribution of principal muscles around the shoulder by electromyography and (2) access the range of motion of 5 movements of patients with RTSA compared with normal shoulders. METHODS: This is an observational prospective cohort study of 21 patients divided into 11 patients with RTSA and 10 controls. The muscular activity was recorded with bipolar cutaneous electrodes, whereas the range of motion was synchronized and recorded by 8 motion cameras. Five movements (flexion, abduction, neutral external rotation, external rotation in 90° of abduction, and internal rotation in 90° of abduction) were studied. RESULTS: The upper trapezius is the main activator in all directions with early and constant activity (P < .01). The latissimus dorsi demonstrates increased muscular activity in internal rotation (P < .01) as well as the posterior deltoid in external rotation in the RTSA group compared with control (P < .01). CONCLUSION: RTSA shoulder muscle activation is significantly different than in normal shoulders. The significant contribution of the trapezius in all directions, latissimus dorsi in internal rotation, and posterior deltoid in external rotation has never been described within the same study until today. New rehabilitation protocols targeting those muscles could demonstrate better and more homogeneous results and increase patient satisfaction.

The Effect of Porous Tantalum Cones on Mechanical Alignment and Canal-Fill Ratio in Revision Total Knee Arthroplasty Performed with Uncemented Stems.

In revision total knee arthroplasty (TKA), the internal diameter of metal cones may limit the ability of the stem to properly fill the medullary canal. We prospectively studied 115 patients who underwent revision TKA with uncemented stems to evaluate the effect of metal cones on mechanical alignment and stem positioning. Correction on the mechanical alignment was well achieved in all patients, regardless of whether a metal cone was used. The proportion of patients achieving restoration of neutral mechanical alignment was similar between groups, as were the mean canal fill ratio (CFR) and the proportion of patients achieving CFR ≥ 85%. The use of porous tantalum cones in revision TKA with uncemented stems is not an obstacle in achieving optimal mechanical alignment and stem positioning.

Traffic in the operating room during joint replacement is a multidisciplinary problem.

BACKGROUND: Door openings disrupt the laminar air flow and increase the bacterial count in the operating room (OR). We aimed to define the incidence of door openings in the OR during primary total joint arthroplasty (TJA) surgeries and determine whether measures were needed and/or possible to reduce OR staff traffic. METHODS: We recorded the number of door openings during 100 primary elective TJA surgeries; the OR personnel were unaware of the observer's intention. Operating time was divided into the preincision period, defined as the time from the opening of surgical trays to skin incision, and the postincision period, defined as time from incision to dressing application. RESULTS: The mean number of door openings during primary TJA was 71.1 (range 35-176) with a mean operative time of 111.9 (range 53-220) minutes, for an average of 0.64 (range 0.36-1.05) door openings/min. Nursing staff were responsible for 52.2% of total door openings, followed by anesthesia staff at 23.9% and orthopedic staff at 12.7%. In the preincision period, we observed an average of 0.84 door openings/ min, with nursing and orthopedic personnel responsible for most of the door openings. The postincision period yielded an average of 0.54 door openings/min, with nursing and anesthesia personnel being responsible for most of the door openings. CONCLUSION: There is a high incidence of door openings during TJA. Because we observed a range in the number of door openings per surgery, we believe it is possible to reduce this number during TJA.

CONTEXTE: Les ouvertures de porte perturbent le flux laminaire et accroissent la numération bactérienne au bloc opératoire. Nous avons voulu mesurer l'incidence des ouvertures de porte au bloc opératoire durant les chirurgies pour prothèse articulaire totale (PAT) et déterminer si des correctifs étaient requis ou s'il était possible de réduire la circulation du personnel au bloc opératoire. MÉTHODES: Nous avons dénombré les ouvertures de porte durant 100 chirurgies électives primaires pour PAT; le personnel du bloc opératoire n'était pas au courant de l'intention de l'observateur. Le temps opératoire a été subdivisé en une période pré-incision, définie par l'intervalle entre l'ouverture des plateaux chirurgicaux et l'incision chirurgicale, et une période post-incision, définie par l'intervalle entre l'incision et l'application du pansement. RÉSULTATS: Le nombre moyen d'ouvertures de porte par intervention pour PAT primaire a été de 71,1 (entre 35 et 176) et la durée moyenne des interventions a été de 111,9 (entre 53 et 220) minutes, pour une moyenne de 0,65 (entre 0,36 et 1,05) ouverture/ minute. Le personnel infirmier était responsable de 52,2 % du nombre total d'ouvertures de porte, suivi du personnel d'anesthésie avec 23,9 % et du personnel d'orthopédie avec 12,7 %. Durant la période pré-incision, nous avons observé une moyenne de 0,84 ouverture de porte/minute, le personnel infirmier et d'orthopédie ayant été responsable de la majorité des ouvertures de porte. La période post-incision a donné lieu à une moyenne de 0,54 ouverture de porte/minute, le personnel infirmier et d'anesthésie ayant été responsable de la majorité des ouvertures de porte. CONCLUSION: On observe un nombre important d'ouvertures de porte durant les interventions pour PAT. Étant donné que ce nombre varie, nous croyons qu'il est possible de le réduire.

Aspirin versus low-molecular-weight heparin for extended venous thromboembolism prophylaxis after total hip arthroplasty: a randomized trial.

BACKGROUND: The role of aspirin in thromboprophylaxis after total hip arthroplasty (THA) is controversial. OBJECTIVE: To compare extended prophylaxis with aspirin and dalteparin for prevention of symptomatic venous thromboembolism (VTE) after THA. DESIGN: Multicenter randomized, controlled trial with a noninferiority design based on a minimal clinically important difference of 2.0%. Randomization was electronically generated; patients were assigned to a treatment group through a Web-based program. Patients, physicians, study coordinators, health care team members, outcome adjudicators, and data analysts were blinded to interventions. (Current Controlled Trials: ISRCTN11902170). SETTING: 12 tertiary care orthopedic referral centers in Canada. PATIENTS: 778 patients who had elective unilateral THA between 2007 and 2010. INTERVENTION: After an initial 10 days of dalteparin prophylaxis after elective THA, patients were randomly assigned to 28 days of dalteparin (n = 400) or aspirin (n = 386). MEASUREMENTS: Symptomatic VTE confirmed by objective testing (primary efficacy outcome) and bleeding. RESULTS: Five of 398 patients (1.3%) randomly assigned to dalteparin and 1 of 380 (0.3%) randomly assigned to aspirin had VTE (absolute difference, 1.0 percentage point [95% CI, -0.5 to 2.5 percentage points]). Aspirin was noninferior (P < 0.001) but not superior (P = 0.22) to dalteparin. Clinically significant bleeding occurred in 5 patients (1.3%) receiving dalteparin and 2 (0.5%) receiving aspirin. The absolute between-group difference in a composite of all VTE and clinically significant bleeding events was 1.7 percentage points (CI, -0.3 to 3.8 percentage points; P = 0.091) in favor of aspirin. LIMITATION: The study was halted prematurely because of difficulty with patient recruitment. CONCLUSION: Extended prophylaxis for 28 days with aspirin was noninferior to and as safe as dalteparin for the prevention of VTE after THA in patients who initially received dalteparin for 10 days. Given its low cost and greater convenience, aspirin may be considered a reasonable alternative for extended thromboprophylaxis after THA.

Arthroscopic Subdeltoid Humeroplasty in the Beach-Chair Position for Reverse Hill-Sachs Lesions.

Reverse Hill-Sachs lesions (HSLs) often involve a greater percentage of the humeral head articular surface than posterior HSLs and frequently require surgical treatment in the setting of posterior shoulder instability. Multiple techniques have been described to treat these lesions depending on their size, acuity, and location. The (modified) McLaughlin procedure is widely used to treat smaller engaging lesions, whereas larger lesions involving a greater percentage of the humeral head articular surface require anatomic disimpaction, termed "humeroplasty." Humeroplasty is traditionally performed via an open approach. This technical note describes an arthroscopic subdeltoid humeroplasty technique for the reduction and fixation of reverse HSLs in the beach-chair position.

Incidence of venous thromboembolism in pediatric orthopedics: A systematic review.

BACKGROUNDS: Children undergoing orthopedic procedures often present numerous risk factors for thromboembolism. A recent survey, conducted by the Pediatric Orthopaedic Society of North America (POSNA), indicates that pediatric orthopedic surgeons are unaware of venous thromboembolism (VTE) prevention protocols and feel that certain procedures should require thromboprophylaxis. The aim of this systematic review was to properly assess the incidence of VTE in pediatric orthopedics. By using a thorough and broad search of the literature, the incidence according to different subspecialties of pediatric orthopedics was evaluated. METHODS: A systematic review on VTE in pediatric orthopedics was conducted. Four databases were searched for articles reporting these events. Three major search concepts: "pediatrics", "orthopedic surgery/trauma" and "VTE complications" were used and broken down in MeSH, EmTree and their free vocabulary synonyms for proper literature review. Two independent authors screened 8467 titles and abstracts. Seventy articles reporting VTE in children treated by orthopedic surgeons were selected for data extraction. We reported median incidences by orthopedic subtypes and by study characteristics with a semi-quantitative review model. RESULTS: The 70 articles yielded a total of 845,010 participants. Spine articles (33/70) provided 25,2% of the children included in the review. Trauma studies (16/70) accounted for 47.5% of the participants. The overall VTE median incidence was 0.16% [95% CI: 0.0-1.01%]. Musculoskeletal infections had a noticeably higher median incidence of 3.5% [CI: 0.0-13.8%]. Small variations were seen for the other subtypes: trauma, spine and elective surgeries. Subgroups by article characteristics did not differ significantly either. CONCLUSION: Thrombotic complications are rare events in pediatric orthopedics, but knowledge epidemiologic is important because its potential severity. In this review, VTE median incidence for all orthopedic subtypes was around 0.16% [CI: 0.0-1.01%]. According to subspecialty assessment, musculoskeletal infections were associated with greater risk of VTE occurrence. LEVEL OF EVIDENCE: III - Systematic review.

Patient Factors Influencing Outcomes at 12-Year Follow-up of Hip Arthroscopy for Femoroacetabular Impingement.

BACKGROUND: Arthroscopic treatment of femoroacetabular impingement has increased in popularity since the early 2000s when it was first described, although only a few midterm follow-up studies have been published. PURPOSE: To describe the outcomes of patients undergoing hip arthroscopy for femoroacetabular impingement at a mean 12-year follow-up and to determine the risk factors for failure. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: The Non-Arthritic Hip Score (NAHS) and a radiographic evaluation were completed preoperatively and at midterm follow-up. Participants were divided into 2 groups according to their clinical evolution. The success group consisted of patients whose NAHS at the final follow-up was above the established Patient Acceptable Symptom State (PASS) threshold of 81.9, whereas patients who underwent a second surgical intervention or did not reach the PASS threshold at final follow-up were assigned to the failure group. These groups were compared to identify preoperative differences in demographic, pathological, and surgical factors. RESULTS: A total of 95 hips were included, after 23 were lost to follow-up (80.5% follow-up). At a mean follow-up of 12.1 years (range, 9.2-16.0 years), 9 hips required total hip arthroplasty (9.5%), 5 required revision hip arthroscopy (5.3%), 29 did not achieve the NAHS PASS threshold (30.5%), and 52 achieved the NAHS PASS threshold (54.7%). The mean NAHS was 82.4 at final follow-up compared with 66.9 preoperatively (mean difference = 15.5; P < .001). Higher mean body mass index (24.9 vs 23.0; P = .030), older age (30.0 vs 27.2; P = .035), and inferior preoperative lateral joint space width (3.9 vs 4.4; P = .019) were associated with inferior prognosis in the failure group versus success group. Osteoarthritis progression was observed in 69.2% of the failure group and in 34.8% of the success group (P = .082). Labral ossification was observed in 78.3% of all patients, and its lateral projection length was statistically associated with failure (P = .015). CONCLUSION: At a mean 12-year follow-up, hip arthroscopy for femoroacetabular impingement led to significant clinical improvement, with 55% PASS achievement. In total, 31% of patients were below the PASS threshold, 5% had revision arthroscopy, and only 9% had conversion to total hip arthroplasty for a 45% global failure rate. Increased body mass index, older age, and smaller preoperative lateral joint space width were significant negative prognostic factors. Postoperative degenerative changes were highly prevalent and demonstrated association with failure.

Lateral knee laxity increases the risk of excessive joint line obliquity after medial opening-wedge high tibial osteotomy.

BACKGROUND: Medial opening-wedge high tibial osteotomy (HTO) is a well-recognized treatment for patient with varus knee osteoarthritis. Joint line obliquity has recently been suggested to negatively impact clinical outcomes following HTO, but little is known about what factors lead to increased joint line obliquity. The purpose of the current study was (1) to evaluate whether increased preoperative lateral knee laxity, represented by the joint line convergence angle, results in increased joint line obliquity in a consecutive series of patients treated with HTO and (2) to determine the effect of advanced arthritic changes on joint line obliquity. HYPOTHESIS: Increased joint line convergence angle would be associated with increased joint line obliquity. PATIENTS AND METHODS: All HTOs performed at our center between 2010-2017 were retrospectively reviewed. Patients were excluded if pre- and postoperative standing alignment radiographs were not available. Varus-producing osteotomies were excluded. Patients were subdivided according to their preoperative joint line convergence angle (≤3° or >3°) and the degree of radiographic arthritic change. The primary outcome measure was the postoperative joint line obliquity. Categorical variables were compared using the paired samples t-test. Survival analysis was performed for failure and overall rate of reoperation. RESULTS: During the study period, 90 HTO were performed, and 38 patients (42 knees; M/F: 32/6; mean age: 41.6; mean follow-up: 4.72 years) met the inclusion criteria. The most common surgical indications were varus knee osteoarthritis (n=27, 64.3%) and osteochondritis dissecans (n=7, 8.2%). Patients with a preoperative joint line convergence angle >3° demonstrated significantly greater joint line obliquity postoperatively as compared to those with a joint line convergence angle ≤3° (6.4°±4.6° vs. 2.5°±5.7°, respectively; p=0.02). Patients with advanced arthritic changes had significantly lower preoperative (-3°±3.4° vs. -5.6°±4.1°; p=0.03) and greater postoperative (5.8°±4° vs. 2.2°±6.4°; p=0.04) joint line obliquity as compared to those with minimal arthritic changes. There were 12 complications among the 42 procedures: one conversion to total knee replacement (TKR), one hardware failure (fixation revised), one infection, and 9 hardware removals. Overall survival using conversion to TKR was 96.23% (95% CI 0.92-1.0) at 10 years. DISCUSSION: Lateral knee laxity, as defined by a preoperative joint line convergence angle >3°, and advanced arthritic changes are associated with increased postoperative joint line obliquity following medial opening-wedge high tibial osteotomy. Soft-tissue adaptation should be accounted for in order to avoid excessive joint line obliquity following high tibial osteotomy, and the planned correction should be reduced by 25% in patients with a preoperative joint line convergence angle >3° when templating using standing alignment radiographs. LEVEL OF EVIDENCE: IV.

Gait pattern analysis before and after periacetabular osteotomy in unilaterally affected dysplastic patients.

BACKGROUND: Patients with acetabular dysplasia have an abnormal acetabular geometry which results in insufficient coverage of the femoral head. This coverage deficiency reduces contact surfaces within the joint, accelerating the wear of the articular cartilage and predisposing patients to early osteoarthritis. Periacetabular osteotomy is a surgical treatment of acetabular dysplasia that aims to reorient the acetabulum relative to the femoral head, increasing coverage. METHODS: Pelvic kinematics and lower limbs joint kinematics and kinetics during the stance phase of gait were recorded using a 3D motion capture system and force plates, then compared pre- to post- and between limbs with a repeated measures 2-way ANOVA. Radiographic measurements and gait parameters were compared pre- to post-surgery using a t-test for dependant samples. To identify predictors of pelvic symmetry improvements during gait, a multivariate analysis was performed using a forward stepwise linear regression. FINDINGS: Radiographic measurements improved for all participants while gait parameters remained unchanged. Hip flexion symmetry was improved following surgery. The external rotation moment of the healthy hip was reduced after surgery (-29%) resulting in increased asymmetry. Pelvic tilt was significantly greater on the affected side (+0.5°) during the loading response, and the difference tended to be greater after surgery (+0.8°). INTERPRETATION: Unilaterally affected dysplastic patients have an asymmetrical gait pattern that is only partially corrected by periacetabular osteotomy even when radiographic and clinical targets are met. Differences between the limbs could be explained in part by a learned antalgic pattern and muscle weaknesses leading to complex compensation mechanisms.

Volar Locking Plating Compared to Conservative Treatment in Distal Radius Fractures in Elderly Patients (>60 years old): A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Purpose: We performed a systematic review and meta-analysis to compare the efficacy of volar locking plating (VLP) to conservative treatment in distal radius fractures in patients aged >60 years old. Methods: English articles were searched in electronic databases including MEDLINE, CENTRAL, Embase, Web of science, and ClinicalTrial.gov from inception to October 2020. Relevant article reference lists also were reviewed. Two reviewers independently screened and extracted data from trials comparing VLP to nonsurgical treatment in distal radial fractures in the elderly. Starting with 3052 citations, 5 trials (539 patients) met the inclusion criteria. The primary outcomes were disabilities of the arm, shoulder, and hand, and patient-rated wrist evaluation scores, grip strength, and range of motion. Results: All trials of this random effect meta-analysis were at a moderate risk of bias due to the lack of blinding. Differences in the disabilities of the arm, shoulder, and hand score (mean difference [MD] -5,91; 95% confidence interval [CI], -8,83; -3,00), patient-rated wrist evaluation score (MD -9.07; 95% CI, -14.57, -3.57), and grip strength (MD 5,12; 95% CI, 0,59-9,65) were statistically significant and favored VLPs, however without reaching clinical significance. No effect was observed in terms of the range of motion and reoperation rates. Conclusion: This review was not able to demonstrate any clinical benefit to the surgical treatment of distal radius fractures with VLP in patients aged >60 years old compared to nonsurgical treatment. Type of study/level of evidence: Therapeutic I.

Prognostic Factors of Function in Nonoperatively Treated Radial Head Fractures: A Prospective Cohort Study.

OBJECTIVES: To identify patient-related factors and fracture characteristics influencing the functional outcomes of nonoperatively treated radial head fractures and to determine function at 1 year. DESIGN: Prospective cohort study. SETTING: Academic Level 1 trauma center. PATIENTS/PARTICIPANTS: Consecutive isolated radial head fractures fitting the inclusion criteria between May 2013 and July 2016. INTERVENTION: Nonoperative treatment of isolated radial head fractures. OUTCOME MEASUREMENTS: Logistic regressions between potential prognostic factors and function assessed with the Mayo Elbow Performance Score (MEPS), the Disabilities of the Arm, Shoulder, and Hand (DASH) score, and range of motion at 1.5-3-6-12 months. RESULTS: One hundred fourteen patients were included (78% Mason I [OTA/AO 2R1B1], 20% Mason II [OTA/AO 2R1B3], and 2% Mason III [OTA/AO 2R1C3]). Mean MEPS and DASH score at the last follow-up were excellent [96.4 ± 7.6 and 3.7 ± 8.6] with, respectively, 79.8% and 92.7% of satisfactory results. Depressive symptoms at injury baseline (Quick Inventory of Depressive Symptomatology > 5) are a constant predictor of unsatisfactory function (MEPS <90 or DASH >17]). Older age and female sex were all linked to worse function at the first follow-ups ( P < 0.05), whereas lower socioeconomic class and receiving financial compensations were associated to unsatisfactory function at 1 year ( P < 0.05). CONCLUSIONS: Although most nonoperatively treated radial head fractures heal with excellent function, some patients still exhibit unsatisfactory results at 1 year. Symptoms of depression at injury baseline are a constant and significant predictor of unsatisfactory function. Early detection of depressive symptoms would allow for interventions that may optimize function. LEVEL OF EVIDENCE: Prognostic Level II.

Validation of the French version of the Non-Arthritic Hip Score (NAHS) in 113 hip arthroscopy procedures.

BACKGROUND: The Non-Arthritic Hip Score (NAHS) used to evaluate the hip in younger patients is a self-administered questionnaire with 20 items in four sections: pain, symptoms, function, and activities. Although used in France, no transcultural version had been validated. The objective of this study was to translate the NAHS into French then assess the validity, reliability, and sensitivity to change of the French-language version (NAHS-Fr) in younger patients with hip conditions other than osteoarthritis. HYPOTHESIS: The NAHS-Fr demonstrates good validity and reliability when used in younger French-speaking patients with hip pain. MATERIAL AND METHODS: We conducted a prospective observational study in 105 patients (62 males and 43 females) scheduled for surgery on one or both hips (113 hips in total) to treat cam-type femoro-acetabular impingement or labral lesions. Before and 6 months after surgery, each patient completed the NAHS-Fr and Western Ontario and McMaster Osteoarthritis Index (WOMAC). Statistical tests were done to evaluate validity, reliability, and sensitivity to change, as recommended by the Consensus-based Standards for the selection of health Measurement Instruments (COSMIN). RESULTS: The response rate was 100%, confirming that the NAHS-Fr was easy to use. The NAHS-Fr was both valid and reliable. No ceiling or floor effect was detected for the total NAHS-Fr score. All items had Cronbach alpha coefficients greater than 0.8, indicating good internal consistency. External consistency between the NAHS-Fr and WOMAC was negative (-0.676) due to inversely proportional score indexing. Before surgery, the NAHS-Fr and WOMAC scores were strongly and significantly correlated (p<0.0001). The effect size was greater than 0.8, indicating good sensitivity to the change induced by surgery. DISCUSSION: These results confirm the study hypothesis: the NAHS-Fr has the same good psychometric characteristics as does the original version and versions in other languages. The NAHS-Fr is useful for evaluating younger patients with non-osteoarthritic hip pain and can be used by French-speaking surgeons in everyday clinical practice. LEVEL OF EVIDENCE: IV, prospective observational non-comparative cohort study.

Continuous vs. single-shot adductor canal block for pain management following primary total knee arthroplasty: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Adductor canal block (ACB) provides effective analgesia following total knee arthroplasty (TKA). This systematic review aimed to compare continuous and single-shot ACB for pain management and functional recovery following TKA. METHODS: MEDLINE, Embase, Web of Science and CENTRAL were searched up to January 5th, 2021. Included studies were randomized controlled trials comparing continuous to single-shot ACB for postoperative pain management after primary TKA. Primary outcome was opioid consumption and secondary outcomes were pain intensity, quadriceps strength, mobility, complications, and length of hospital stay. Meta-analyses were performed using random-effects method. RESULTS: Eleven studies (910 patients) were included in this systematic review. Continuous ACB did not significantly decrease opioid consumption (8 studies; 642 patients; MD=-5.67; 95% CI: -13.87 to 2.54; I2=13%) but significantly decreased 48hours pain scores (10 studies; 852 patients; MD=-0,73; 95% CI: -0.93 to -0.54; I2=54%). Continuous ACB improved quadriceps strength (4 studies; 250 patients; SMD=0.59; 95% CI: 0.16 to 1.03; I2=63%) but not Timed Up and Go test performance (5 studies; 524 patients; MD=3.99; 95% CI: -8.98 to 1.01; I2=89%). Type of ACB did not affect nausea and vomiting (5 studies; 357 patients; RR=1.23; 95% CI: 0.65 to 2.34; I2=0%) nor length of hospital stay (8 studies; 655 patients; MD=-0.13; 95% CI: -0.28 to 0.01; I2=36%). CONCLUSION: Continuous ACB did not reduce opioid consumption following TKA. Larger trials are required.
