Early Postoperative Activities of Daily Living Do Not Adversely Affect Joint Torques or Translation Regardless of Capsular Condition: A Cadaveric Study.

PURPOSE: To evaluate the impact of capsular management on joint constraint and femoral head translations during simulated activities of daily living (ADL). METHODS: Using 6 (n = 6) cadaveric hip specimens, the effect of capsulotomies and repair was then evaluated during simulated ADL. Joint forces and rotational kinematics associated with gait and sitting, adopted from telemeterized implant studies, were applied to the hip using a 6-degrees of freedom (DOF) joint motion simulator. Testing occurred after creation of portals, interportal capsulotomy (IPC), IPC repair, T-capsulotomy (T-Cap), partial T-Cap repair, and full T-Cap repair. The anterior-posterior (AP), medial-lateral (ML), and axial compression DOFs were operated in force control, whereas flexion-extension, adduction-abduction, and internal-external rotation were manipulated in displacement control. Resulting femoral head translations and joint reaction torques were recorded and evaluated. Subsequently, the mean-centered range of femoral head displacements and peak signed joint restraint torques were calculated and compared. RESULTS: During simulated gait and sitting, the mean range of AP femoral head displacements with respect to intact exceeded 1% of the femoral head diameter after creating portals, T-Caps, and partial T-Cap repair (Wilcoxon signed rank P < .05); the mean ranges of ML displacements did not. Deviations in femoral head kinematics varied by capsule stage but were never very large. No consistent trends with respect to alterations in peak joint restrain torques were observed. CONCLUSIONS: In this cadaveric biomechanical study, capsulotomy and repair minimally affected resultant femoral head translation and joint torques during simulated ADLs. CLINICAL RELEVANCE: The tested ADLs appear safe to perform after surgery, regardless of capsular status, because adverse kinematics were not observed. However, further study is required to determine the importance of capsular repair beyond time-zero biomechanics and the resultant effect on patient-reported outcomes.

Improvement in pain and patient-related outcome measures following hip arthroscopy in patients with femoroacetabular impingement syndrome and concomitant generalized ligamentous laxity: a systematic review.

PURPOSE: Within orthopaedic sports medicine, concomitant ligamentous laxity is often found to be a negative prognostic factor for post-operative outcomes following various procedures. The effect of ligamentous laxity on outcomes following hip arthroscopy remains infrequently reported. Therefore, the purpose of this study is to report on the outcomes of hip arthroscopy for the treatment of femoroacetabular impingement syndrome (FAIS) with concomitant generalized ligamentous laxity (GLL). METHODS: A systematic search was performed in Medline, EMBASE, CENTRAL, and SPORTDiscus (from inception to April 2021) for studies reporting outcomes following hip arthroscopy for symptomatic FAIS in patients with concomitant GLL. RESULTS: Six studies representing 213 patients and 231 hips were included. Outcomes of pain and functional scores as measured by VAS, Harris Hip Score, and Hip Disability and Osteoarthritis Outcomes Score were tabulated. A mean improvement of 4.8 on VAS was observed. Improvements of 30.0 on HHS, 33.1 for ssHOS, and 23.9 for ADL-HOS were observed. CONCLUSION: Hip arthroscopy is an effective method of alleviating pain and improving function with statistically significant improvements in all PROM in patients with concomitant FAIS with GLL.

Mild to moderate osteoarthritis is not considered a contraindication to arthroscopic treatment of symptomatic femoroacetabular impingement: results of an international survey.

PURPOSE: Hip arthroscopy offers a minimally invasive approach for the treatment of femoroacetabular impingement (FAI). Although osteoarthritis (OA) is a known negative prognostic factor for arthroscopy, it is unclear if patients with FAI and concomitant mild to moderate OA benefit from hip preservation surgery. The goal of this study was to evaluate current practice patterns among surgeons experienced in FAI management in the treatment of patients between 40 and 60 years of age with symptomatic FAI and concomitant OA of varying severity. METHODS: A 12-question cross-sectional survey was distributed using a secure electronic survey portal. The survey sought to determine surgical treatment of FAI in patients between the ages of 40 and 60 years old with concomitant OA of various degrees. Surveys were completed electronically and anonymously, with invitations distributed to members of the American Orthopaedic Society for Sports Medicine, International Society for Hip Arthroscopy, Arthroscopy Association of Canada, Canadian Orthopaedic Association, and both current and former Fowler Kennedy sports medicine fellows. RESULTS: A total of 76 orthopedic surgeons who treat FAI completed the survey. All respondents routinely treat FAI arthroscopically, while only 43.7% have utilized an open surgical approach. Nearly all respondents (96.0%) would consider performing hip arthroscopy in patients over 40 years of age. The respondents ranked an absence of OA (Tönnis 0 or 1) as the most important factor in deciding to move forward with surgery, while a positive response to diagnostic injection was considered the least important factor of the options given. Respondents felt that the role for hip arthroscopy in patients with symptomatic FAI decreased with increasing age and worsening degree of osteoarthritis. In patients 40-50 years old with Tönnis 1, willingness to perform surgery was 89.5%; while with Tönnis 2 this was reduced to 39.5% and with Tönnis 3 it was 5.3%. In patients 50-60 years old with Tönnis 1, 80.3% of respondents found arthroscopy to be beneficial; while with Tönnis 2 this was reduced to 22.4% and with Tönnis 3 it was 2.6%. CONCLUSIONS: Most respondents consider arthroscopy a viable option for patients aged 40-60 years old with mild osteoarthritis (Tönnis 1), while worsening osteoarthritis (Tönnis 3) results in greater rates of non-arthroscopic treatment. The role of arthroscopy with moderate osteoarthritis (Tönnis 2) remains unclear and should be a focus for future studies. LEVEL OF EVIDENCE: Level V.

Systematic review of grading systems for adverse surgical outcomes.

Background: Grading scales for adverse surgical outcomes have been poorly characterized to date. The primary aim of this study was to conduct a systematic review to enumerate the various frameworks for grading adverse postoperative outcomes; our secondary objective was to outline the properties of each grading system, identifying its strengths and weaknesses. Methods: We searched 9 databases (Africa Wide Information, Biosis, Cochrane, Embase, Global Health, LILACs, Medline, PubMed and Web of Science) from 1992 (the year the Clavien-Dindo classification system was developed) until Mar. 2, 2017, for studies that aimed to develop or improve on an already existing generalizable system for grading adverse postoperative outcomes. Study selection was duplicated as per PRISMA recommendations. Procedure-specific grading systems were excluded. We assessed the framework, strengths and weaknesses of the systems qualitatively. Results: We identified 9 studies on 8 adverse outcome grading systems with frameworks generalizable to any surgical procedure. Most systems have not been widely incorporated in the literature. Seven of the 8 systems were produced without including patients' perspectives. Four allowed the derivation of a composite morbidity score, which had limited tangible significance for patients. Conclusion: Although each instrument identified offered its own advantages, none satisfied the need for a patient-centred tool capable of generating a composite score of all possible postoperative adverse outcomes (complications, sequelae and failure) that enables comparison of noninterventional and surgical management of disease. There is a need for development of a more comprehensive, patient-centred grading system for adverse postoperative outcomes.

Contexte: Jusqu'ici, les systèmes de classification des issues postopératoires indésirables n'ont pas encore fait l'objet d'une analyse comparative. Cette étude avait pour objectif principal de recenser, au moyen d'une revue systématique de la littérature, les divers systèmes de classification des issues postopératoire indésirables, et pour objectif secondaire de dégager les propriétés, les forces et les faiblesses de chaque système. Méthodes: Nous avons interrogé 9 bases de données (Africa Wide Information, Biosis Previews, Cochrane, Embase, Global Health, LILACS, Medline, PubMed et Web of Science) pour trouver des articles publiés entre 1992 (année de la mise au point du système de classification de Clavien­Dindo) et le 2 mars 2017. Ces articles devaient porter sur la création d'un système généralisable de classification des issues postopératoires indésirables, ou l'amélioration d'un système existant. La sélection des études a été faite en double, conformément aux recommandations PRISMA. Les systèmes de classification visant une seule intervention ont été exclus. Nous avons évalué, d'un point de vue qualitatif, le cadre, les forces et les faiblesses des systèmes retenus. Résultats: Nous avons retenu 9 études sur 8 systèmes de classification accompagnés d'un cadre pouvant être appliqué à n'importe quelle intervention chirurgicale. La plupart des systèmes n'avaient pas été largement étudiés. Sept des 8 systèmes avaient été développés sans tenir compte du point de vue des patients, et 4 permettaient de calculer un score de morbidité composite ayant des retombées concrètes limitées pour les patients. Conclusion: Tous les systèmes retenus s'accompagnaient d'avantages, mais aucun ne pouvait servir d'outil centré sur le patient permettant de calculer un score composite pour toutes les issues postopératoires possibles (complications, séquelles et échec), score qui pourrait servir à comparer les prises en charge conservatrice et chirurgicale des maladies. La création d'un système de classification des issues postopératoires indésirables exhaustif centré sur le patient est nécessaire.

Operating Room Educational Environment in Canada: Perceptions of Surgical Residents.

OBJECTIVE: The educational experience in operating rooms (OR) plays a central role in the transformation of a trainee into a surgeon. As Canadian residency programs transition to competency-based medical education, and since most surgical competencies are attained in the OR, we investigated the perceptions of Canadian surgical residents about their OR learning environment. DESIGN: Cross-sectional, national survey. SETTING: An online questionnaire, including the validated 40-item operating room educational environment measure (OREEM) inventory, was sent to residency programs of all surgical specialties in Canada. The OREEM assesses the trainees' perceptions of the "trainer and training," "learning opportunities," "atmosphere in the operating room," "supervision, workload, and support," Each individual item was rated using a 5-point Likert scale ranging from "strongly disagree" (scores 1) to "strongly agree" (scores 5). The mean score of each individual item was measured, and the mean scores of each subscale and an overall score of the questions were also measured. PARTICIPANTS: Surgical residents in Canada. RESULTS: Four hundred thirty residents were included for final analysis. The overall mean OREEM score was 3.72 ± 0.4. "Atmosphere in the OR" was the subscale with the highest mean score (3.87 ± 0.5), while "supervision, workload, and support" had the lowest subscale mean score (3.49 ± 0.5). The overall OREEM mean score for junior and senior residents was 3.67 ± 0.4 and 3.80 ± 0.4, respectively (p = 0.001). No significant differences were seen in the mean OREEM score between males and females or different surgical programs. Nevertheless, general surgery had the lowest "supervision, workload, and support" subscale score (3.27 ± 0.5; p < 0.001). CONCLUSIONS: The overall educational environment in OR may be considered satisfactory as perceived by Canadian surgical residents; however, several areas for potential improvement are identified and suggestions for optimizing the learning environment are described.

Incidence and prevalence of congenital anomalies in low- and middle-income countries: A systematic review.

BACKGROUND: In the absence of robust data from low- and middle-income countries (LMICs), most disease burden estimates and related resource allocation choices are based on historic Northern demographics. We hypothesize that significant discrepancies exist between directly reported LMIC data and surrogate high-income country (HIC) disease burden estimates of correctible congenital anomalies. METHODS: Nine online databases were searched for studies reporting incidence and prevalence data on surgically correctible congenital anomalies in LMICs between 2006 and 2017. Two independent reviewers screened titles and abstracts, with a third adjudicating discrepancies. Selected studies were reviewed and analyzed. RESULTS: Of 10,128 identified articles, 98 were extracted for full-text review, and 41 were included, representing 21 LMICs and 18 conditions. Study types included community surveys (34%), prospective (22%) and retrospective (17%) multi-site data, registries (12%), single-site data (12%), and systematic reviews (5%). Data collection periods were 1 to 10 years. The pooled epidemiologic data varied systematically from existing HIC literature, with the incidence of disease being generally lower in LMICs. CONCLUSIONS: Marked discrepancies exist between reported epidemiological data in LMICs and HIC literature, in part owing to varying quality of data collection in LMICs. Robust population-based surveys are needed to accurately estimate the burden of surgically correctable congenital anomalies in LMICs.

Pediatric surgical capacity in Africa: Current status and future needs.

BACKGROUND: African pediatric surgery (PS) faces multiple challenges. Information regarding existing resources is limited. We surveyed African pediatric surgeons to determine available resources and clinical, educational, and collaborative needs. METHODS: Members of the Pan-African Pediatric Surgical Association (PAPSA) and the Global Pediatric Surgery Network (GPSN) completed a structured email survey covering PS providers, facilities, resources, workload, education/training, disease patterns, and collaboration priorities. RESULTS: Of 288 deployed surveys, 96 were completed (33%) from 26 countries (45% of African countries). Median PS providers/million included 1 general surgeon and 0.26 pediatric surgeons. Median pediatric facilities/million included 0.03 hospitals, 0.06 ICUs, and 0.17 surgical wards. Neonatal ventilation was available in 90% of countries, fluoroscopy in 70%, TPN in 50%, and frozen section pathology in 35%. Median surgical procedures/institution/year was 852. Median waiting time was 40days for elective procedures and 7 days? for emergencies. Weighted average percent mortality for key surgical conditions varied between 1% (Sierra Leone) and 54% (Burkina Faso). Providers ranked collaborative professional development highest and direct clinical care lowest priority in projects with high-income partners. CONCLUSIONS: The broad deficits identified in PS human and material resources in Africa suggest the need for a global collaborative effort to address the PS gaps. LEVEL OF EVIDENCE: Level 5, expert opinion without explicit critical appraisal.
