Introduction: A dramatic increase in the number of pediatric orthopaedic fellows being trained has led to concerns that there may be an oversupply of pediatric orthopaedists. The purpose of this study was to determine whether this perception is accurate and whether the practice expectations of recent pediatric fellowship graduates are being met by surveying recent pediatric fellowship graduates about their early practice experiences. Methods: A 36-question survey approved by the Pediatric Orthopaedic Society of North America (POSNA) leadership was electronically distributed to 120 recent graduates of pediatric orthopaedic fellowships; 81 responses were ultimately obtained (67.5% response rate). Results: Almost all (91%) of the respondents were very or extremely satisfied with their fellowship experience. Half of the respondents had at least 1 job offer before they entered their fellowships. After completion of fellowships, 35% received 1 job offer and 62.5% received ≥2 job offers; only 2.5% did not receive a job offer. Most reported a practice consisting almost entirely of pediatric orthopaedics, and 93.5% thought this was in line with their expectations; 87% indicated satisfaction with their current volume of pediatric orthopaedics, and 85% with the complexity of their pediatric orthopaedic cases. Despite the high employment percentages and satisfaction with practice profiles, nearly a third (28%) of respondents replied that too many pediatric orthopaedists are being trained. Conclusions: Positive messages from this survey include the satisfaction of graduates with their fellowship training, the high percentage of graduates who readily found employment, and the satisfaction of graduates with their current practice environments; this indicates that the pediatric orthopaedic job environment is not completely saturated and there are continued opportunities for graduating pediatric fellows despite the increased number of fellows being trained. Although not determined by this study, it may be that the stable demand for pediatric orthopaedic services is being driven by the expansion of the scope of practice as well as subspecialization within the practice of pediatric orthopaedics.

Background: Multiligament knee injuries (MLKIs) can also involve the medial patellofemoral ligament (MPFL), but there is a paucity of information regarding prevalence and relevance of MPFL involvement in this setting. Purpose: (1) To identify the prevalence of MPFL injury in MLKIs, (2) to determine whether an MPFL tear results in symptomatic patellar instability, and (3) to report clinical and functional outcomes of patients with and without MPFL tears after MLKI surgical reconstruction. Study Design: Cohort study; Level of evidence, 3. Methods: The records of all patients who underwent surgical reconstruction of MLKI (defined as a grade 3 injury of ≥2 ligaments) at a single institution from 2007 to 2010 were reviewed. Age, sex, knee dislocation classification (according to Schenck), and MRI findings were documented. All preoperative MRI scans were reviewed by an experienced musculoskeletal radiologist to determine the presence or absence of MPFL involvement. If an MPFL tear was present, its anatomic location and severity as well as the presence of patellar or lateral femoral condyle bone bruises were documented. Inclusion criteria included (1) MLKI treated at a single institution, (2) presence of MPFL tear on preoperative MRI, and (3) minimum 2-year clinical follow-up. Patellar instability symptoms were assessed with the Kujala Knee Questionnaire. Functional outcomes were measured using the International Knee Documentation Committee (IKDC) score. IKDC scores were compared between patients who sustained MLKIs with and without MPFL tears. There were 21 patients in each group. Results: Over the 4-year study period, 30 of 51 patients (59%) treated surgically for a MLKI had MRI evidence of an MPFL tear. Nine were lost to follow-up, leaving 21 patients for review. There were 13 complete (62%), 5 high-grade partial (24%), and 3 partial (14%) MPFL tears. Sixteen of 21 tears (76%) occurred at the proximal third, with the remainder exhibiting diffuse signal abnormality consistent with tearing throughout the length of the MPFL. The superficial medial collateral ligament was involved in all patients. In no case was the MPFL repaired or reconstructed. At mean follow-up of 3.6 years (range, 2.0-5.7 years), only 1 of 21 patients (5%) complained of patellofemoral instability symptoms whereas 20 of 21 patients (95%) did not experience patellar subluxation or dislocation. No significant difference was found when IKDC scores were compared between patients with and without an MPFL tear (mean ± SD, 65.5 ± 22.9 vs 79.4 ± 16.1; P = .07). Conclusion: MPFL tears occur frequently in patients with MLKI but rarely cause instability. In the majority of cases, MPFL tears do not need to be addressed at the time of surgery.

Context Self‐regulated learning ( SRL ) requires an active learner who has developed a set of processes for managing the achievement of learning goals. Simulation‐based training is one context in which trainees can safely practise learning how to learn. Objectives The purpose of the present study was to evaluate, in the simulation‐based training context, the effectiveness of interventions designed to support trainees in SRL activities. We used the social‐cognitive model of SRL to guide a systematic review and meta‐analysis exploring the links between instructor supervision, supports or scaffolds for SRL , and educational outcomes. Methods We searched databases including MEDLINE and Scopus, and previous reviews, for material published until December 2011. Studies comparing simulation‐based SRL interventions with another intervention for teaching health professionals were included. Reviewers worked independently and in duplicate to extract information on learners, study quality and educational outcomes. We used random‐effects meta‐analysis to compare the effects of supervision (instructor present or absent) and SRL educational supports (e.g. goal‐setting study guides present or absent). Results From 11 064 articles, we included 32 studies enrolling 2482 trainees. Only eight of the 32 studies included educational supports for SRL . Compared with instructor‐supervised interventions, unsupervised interventions were associated with poorer immediate post‐test outcomes (pooled effect size: −0.34, p = 0.09; n = 19 studies) and negligible effects on delayed (i.e. > 1 week) retention tests (pooled effect size: 0.11, p = 0.63; n = 8 studies). Interventions including SRL supports were associated with small benefits compared with interventions without supports on both immediate post‐tests (pooled effect size: 0.23, p = 0.22; n = 5 studies) and delayed retention tests (pooled effect size: 0.44, p = 0.067; n = 3 studies). Conclusions Few studies in the simulation literature have designed SRL training to explicitly support trainees’ capacity to self‐regulate their learning. We recommend that educators and researchers shift from thinking about SRL as learning alone to thinking of SRL as comprising a shared responsibility between the trainee and the instructional designer (i.e. learning using designed supports that help prepare individuals for future learning).

AbstractClinical research ethics consultation services have been established across academic health centers over the past decade. This paper presents the results of collaboration within the CTSA consortium to develop a standard approach to the collection of research ethics consultation information to serve as a foundation for quality improvement, education, and research efforts. This approach includes categorizing and documenting descriptive information about the requestor, research project, the ethical question, the consult process, and describing the basic structure for a consult note. This paper also explores challenges in determining how to share some of this information between collaborating institutions related to concerns about confidentially, data quality, and informatics. While there is much still to be learned to improve the process of clinical research ethics consultation, these tools can advance these efforts, which, in turn, can facilitate the ethical conduct of research.

Objective Atrial fibrillation (AF) often progresses from paroxysmal or persistent to more sustained forms, but the rate and predictors of AF progression in clinical practice are not well described. Methods Using the Outcomes Registry for Better Informed Treatment of AF, we analysed the incidence and predictors of progression and tested the discrimination and calibration of the HATCH (hypertension, age, TIA/stroke, chronic obstructive pulmonary disease, heart failure) and CHA2DS2VASc scores for identifying AF progression. Results Among 6235 patients with paroxysmal or persistent AF at baseline, 1479 progressed, during follow-up (median 18 (IQR 12–24) months). These patients were older and had more comorbidities than patients who did not progress (CHADS2 2.3±1.3 vs 2.1±1.3, p<0.0001). At baseline, patients with AF progression were more often on a rate control as opposed to a rhythm control strategy (66 vs 56%, p<0.0001) and had higher heart rate (72(64–80) vs 68(60–76) bpm, p<0.0001). The strongest predictors of AF progression were AF on the baseline ECG (OR 2.30, 95% CI 1.95 to 2.73, p<0.0001) and increasing age (OR 1.16, 95% CI1.09 to 1.24, p<0.0001, per 10 increase), while patients with lower heart rate (OR 0.84, 95% CI 0.79 to 0.89, p<0.0001, per 10 decrease ≤80) were less likely to progress. There was no significant interaction between rhythm on baseline ECG and heart rate (p=0.71). The HATCH and CHA2DS2VASc scores had modest discriminatory power for AF progression (C-indices 0.55 (95% CI 0.53 to 0.58) and 0.55 (95% CI 0.52 to 0.57)). Conclusions Within 1.5 years, almost a quarter of the patients with paroxysmal or persistent AF progress to a more sustained form. Progression is strongly associated with heart rate, and age.

Abstract Lateral hip pain along with tenderness of the greater trochanter has been associated with greater trochanteric pain syndrome. Radiographically, this has been associated with gluteus medius pathology on magnetic resonance imaging. This has led some surgeons to conclude that abductor pathology is a primary cause of lateral hip pain. Failure of conservative treatment in the setting of gluteus medius pathology may lead to surgical intervention. In some patients a focal tear of the gluteus medius cannot be visualized and likely represents more diffuse tendinopathy. In these patients we propose micropuncture of the greater trochanter. Similar procedures have shown effectiveness in the elbow and shoulder by eliciting a healing response. Our experience suggests that trochanteric micropuncture at the insertion of the gluteus medius tendon can be effectively performed endoscopically for gluteus medius tendinopathy.
