Synchronous Web-Based Psychotherapy for Mental Disorders From a Health Quality Perspective: Scoping Review.

BACKGROUND: The COVID-19 pandemic necessitated rapid changes to health care delivery, including a shift from in-person to digitally delivered psychotherapy. While these changes helped ensure timely psychotherapy provision, many concerns exist, including clinical, cultural, practical, privacy, and security issues. OBJECTIVE: This scoping review systematically mapped existing peer-reviewed research on synchronous, therapist-delivered web-based psychotherapy for individuals with a diagnosed mental illness. Data were analyzed through the lens of the Alberta Quality Matrix for Health (AQMH) to assess to what degree this literature addresses key indicators of health care quality. This analysis aided in the identification and organization of knowledge gaps with regard to web-based psychotherapies, highlighting potential disparities between previously prioritized dimensions of care and those requiring further attention. METHODS: This review adhered to the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews) guidelines. We included peer-reviewed primary research studies in the English language investigating synchronous, therapist-delivered remote psychotherapy delivered to adults (aged 18 years and older) with a Diagnostic and Statistical Manual of Mental Disorders or International Statistical Classification of Diseases diagnosed mental illness. All other citations were excluded. Relevant studies were identified through MEDLINE, APA PsycINFO, Embase (OVID), Web of Science: Core Collection (Clarivate), Cochrane Library (Wiley), and Scopus (Elsevier) databases. Databases were searched on March 18, 2021. For every publication that was taken into consideration, the data were charted independently by 2 reviewers, and in the event of a discrepancy, the principal investigator validated the choice of either extractor. Results were thematically described according to the 6 AQMH dimensions: acceptability, accessibility, appropriateness, effectiveness, efficiency, and safety. RESULTS: From 13,209 publications, 48 articles were included, largely from North American studies. Most studies measured treatment effectiveness (n=48, 100%) and acceptability (n=29, 60%) health quality dimensions. Over 80% (40/48) of studies investigated either a cognitive or exposure intervention for either posttraumatic stress disorder or a mood or anxiety disorder, generally indicating comparable results to in-person therapy. Safety (n=5, 10%) was measured in fewer studies, while treatment accessibility, appropriateness, and efficiency were not explicitly measured in any study, although these dimensions were mentioned as a future direction, hypothesis, or potential outcome. CONCLUSIONS: In relation to web-based therapist-delivered psychotherapies for those with a diagnosed mental illness, important aspects of health care quality (accessibility, appropriateness, efficiency, and safety) have received little scientific examination, underscoring a need to address these gaps. There are also significant issues related to the generalizability of this literature, including the underrepresentation of many geographic regions, cultures, populations, clinical contexts, and psychotherapy modalities. Qualitative research in underrepresented populations and settings may uncover important patient and contextual factors important for the future implementation of quality web-based psychotherapy.

Investigating uses of peer-operated Virtual Overdose Monitoring Services (VOMS) beyond overdose response: a qualitative study.

Background: Virtual overdose monitoring services (VOMS) are novel technologies that allow remote monitoring of individuals while they use substances (especially those who use alone) electronically.Objectives: The authors explored key partner perspectives regarding services offered by VOMS beyond overdose response with the aim of understanding the breadth and perception of the services amongst those that use these services and are impacted by them.Methods: Forty-seven participants from six key partner groups [peers who had used VOMS (25%), peers who had not used VOMS (17%), family members of peers (11%), health professionals (21%), harm reduction sector employees (15%), and VOMS operators (15%)] underwent 20-to-60-minute semi-structured telephone interviews. Of peer and family groups, thirteen participants identified as female, eleven as male and one as non-binary, gender data was not recorded for other key partner groups. Interview guides were developed and interviews were conducted until saturation was reached across all participants. Themes and subthemes were identified and member checked with partner groups.Results: Participants indicated that uses of VOMS beyond overdose monitoring included: (1) providing mental health support and community referral; (2) methamphetamine agitation de-escalation; (3) advice on self-care and harm reduction; and (4) a sense of community and peer support. Respondents were divided on how VOMS might affect emergency services (5).Conclusions: VOMS are currently being used for purposes beyond drug poisoning prevention, including community methamphetamine psychosis de-escalation, mental health support, and community peer support. VOMS are capable of delivering a broad suite of harm reduction services and referring clients to recovery-oriented services.

Beliefs, attitudes and experiences of virtual overdose monitoring services from the perspectives of people who use substances in Canada: a qualitative study.

BACKGROUND: Solitary use of substances is a risk factor for substance use-related mortality. Novel e-health harm reduction interventions such as virtual overdose monitoring services (VOMS) have emerged in North America to improve access to emergency overdose support for people who use substances (PWUS). To date, little research has been published, and the perspectives of PWUS are needed to inform evaluation and policy efforts. OBJECTIVE: To explore the beliefs, values and perceptions of PWUS around using and accessing VOMS in Canada. METHODS: A qualitative study following grounded theory methodology was conducted. Using existing peer networks, purposive and snowball sampling was conducted to recruit PWUS (≥ 18 years) with previous experience with VOMS. Thematic analysis was used to analyze twenty-three interviews. Several methods were employed to enhance rigor, such as independent data coding and triangulation. RESULTS: Twenty-three one-on-one telephone interviews of PWUS with previous experience with VOMS were completed and analyzed. The following themes emerged: (1) feelings of optimism around VOMS to save lives; (2) privacy/confidentiality was highly valued due to stigma and fear of arrest; (3) concerns with reliable cell phones negatively impacting VOMS uptake; (4) concerns around emergency response times, specifically in rural/remote communities; (5) desire for trusting relationships with VOMS operators; (6) importance of mental health supports and referrals to psychosocial services; and (7) possible limited uptake due to low public awareness of VOMS. CONCLUSION: This qualitative study provided novel insights about the VOMS from the perspectives of PWUS. PWUS generally felt optimistic about the potential of VOMS as a suitable harm reduction intervention, but several potential barriers around accessing VOMS were identified that may limit uptake. Future research is warranted.

Biomechanical Comparison of Volar Fixed-Angle Locking Plates for AO C3 Distal Radius Fractures: Titanium Versus Stainless Steel With Compression.

PURPOSE: To determine biomechanical differences between a fixed-angle locking volar titanium plate (VariAx; Stryker, Kalamazoo, MI) and a fixed-angle compression locking volar stainless steel plate (CoverLoc Volar Plate; Tornier, Amsterdam, Netherlands) in the fixation of simulated AO C3 distal radius fractures. METHODS: Eighteen cadaveric upper extremities (9 matched pairs) with an average age of 54 years were tested. A 4-part AO C3 fracture pattern was created in each specimen. The fractures were reduced under direct vision and fixed with either the fixed-angle locking volar titanium plate or the fixed-angle compression locking volar stainless steel plate. Motion tracking analysis was then performed while the specimens underwent cyclic loading. Changes in displacement, rotation, load to failure, and mode of failure were recorded. RESULTS: The fragments, when secured with the fixed-angle compression locking stainless steel construct, demonstrated less displacement and rotation than the fragments secured with the fixed-angle locking titanium plate under physiological loading conditions. In the fixed-angle compression locking stainless steel group, aggregate displacement and rotation of fracture fragments were 5 mm and 3° less, respectively, than those for the fixed-angle locking titanium group. The differences between axial loads at mechanical failure and stiffness were not statistically significant. The compression locking stainless steel group showed no trend in mode of failure, and the locking titanium plate group failed most often by articular fixation failure (5 of 9 specimens). CONCLUSIONS: The fixed-angle compression locking stainless steel volar plate may result in less displacement and rotation of fracture fragments in the fixation of AO C3 distal radius fractures than fixation by the fixed-angle locking volar titanium plate. However, there were no differences between the plates in mechanical load to failure and stiffness. CLINICAL RELEVANCE: Fixation of distal radius AO C3 fracture patterns with the fixed-angle compression locking stainless steel plate may provide improved stability of fracture fragments.

Patient-reported outcomes on sleep quality and circadian rhythm during treatment with intravenous ketamine for treatment-resistant depression.

Background: Intravenous (IV) ketamine is a rapid acting antidepressant used primarily for treatment-resistant depression (TRD). It has been suggested that IV ketamine's rapid antidepressant effects may be partially mediated via improved sleep and changes to the circadian rhythm. Objectives: This study explores IV ketamine's association with changes in patient-reported sleep quality and circadian rhythm in an adult population with TRD. Methods: Adult patients (18-64 years) with TRD scheduled for IV ketamine treatment were recruited to complete patient rated outcomes measures on sleep quality using the Pittsburgh Sleep Quality Index (PSQI) and circadian rhythm using the Morningness-Eveningness Questionnaire (MEQ). Over a 4-week course of eight ketamine infusions, reports were obtained at baseline (T0), prior to second treatment (T1), prior to fifth treatment (T2), and 1 week after eighth treatment (T3). Results: Forty participants with TRD (mean age = 42.8, 45% male) were enrolled. Twenty-nine (72.5%) had complete follow-up data. Paired t tests revealed statistically significant improvements at the end of treatment in sleep quality (PSQI) (p = 0.003) and depressive symptoms (Clinically Useful Depression Outcome Scale-Depression, p < 0.001) while circadian rhythm (MEQ) shifted earlier (p = 0.007). The PSQI subscale components of sleep duration (p = 0.008) and daytime dysfunction (p = 0.001) also improved. In an exploratory post hoc analysis, ketamine's impact on sleep quality was more prominent in patients with mixed features, while its chronobiotic effect was prominent in those without mixed features. Conclusion: IV ketamine may improve sleep quality and advance circadian rhythm in individuals with TRD. Effects may differ in individuals with mixed features of depression as compared to those without. Since this was a small uncontrolled study, future research is warranted.

Patient-reported changes in sleep during treatment with intravenous ketamine for depression Intravenous ketamine is a fast acting treatment for depression that does not respond to more conventional antidepressant medications. Almost all people with depression have problems with sleep as a symptom of their illness. This can include things like difficulties falling asleep, problems staying asleep, sleeping more or less than usual, and shifting the sleep schedule to stay up later than usual. It has been previously suggested that improving sleep in people with depression may be part of how ketamine exerts its antidepressant effect. This study surveyed patients with depression who received eight intravenous infusions of ketamine (two per week for 4 weeks) to ask them about their sleep quality and patterns before treatment, part way through their course of treatment and after the treatments were completed. Symptoms of depression were also measured. Data were collected on 29 people. People reported overall that sleep quality did improve with ketamine treatments, and that timing of sleep shifted earlier. Sleep duration increased and people had less problems with daytime functioning. There is a subtype of depression called depression with "mixed features," meaning that these people, in addition to being depressed, may have some activating symptoms like irritability, restlessness, and agitation. It is thought that this type of depression may be biologically different from depression without these symptoms. In this study, around half (15/29) had mixed features. Sleep quality improved only in the group without mixed features. On the other hand, the group with mixed features had their sleep schedule shift earlier, but the group without mixed features did not. This supports the idea that these two types of depression may be biologically different, and ketamine treatment may exert different effects on the sleep of each group. This was a small study, but suggests a need for future research.

Ensemble Detection of DNA Engineering Signatures.

Synthetic biology is creating genetically engineered organisms at an increasing rate for many potentially valuable applications, but this potential comes with the risk of misuse or accidental release. To begin to address this issue, we have developed a system called GUARDIAN that can automatically detect signatures of engineering in DNA sequencing data, and we have conducted a blinded test of this system using a curated Test and Evaluation (T&E) data set. GUARDIAN uses an ensemble approach based on the guiding principle that no single approach is likely to be able to detect engineering with perfect accuracy. Critically, ensembling enables GUARDIAN to detect sequence inserts in 13 target organisms with a high degree of specificity that requires no subject matter expert (SME) review.

Virtual overdose monitoring services and overdose prevention technologies: Opportunities, limitations, and future directions.

Overdose mortality has continued to rise in North America and across the globe in people who use drugs. Current harm reduction strategies such as supervised consumption sites and naloxone kit distribution have been important public health strategies implemented to decrease the harms associated with illicit drug use however have key limitations which prevent their scalability. This is represented in statistics which indicate that the vast majority of overdose mortality occur in individuals who use drugs by themselves. To address this, virtual overdose monitoring services and overdose detection technologies have emerged as an adjunct solution that may help improve access to harm reduction services for those that cannot or choose not to access current in-person services. This article outlines the current limitations of harm reduction services, the opportunities, challenges, and controversies of these technologies and services, and suggests avenues for additional research and policy development.

Preexisting mental health disorders and risk of opioid use disorder in young people: A case-control study.

AIM: Opioid use disorder (OUD) is a leading cause of preventable mortality amongst young people worldwide. Early identification and intervention of modifiable risk factors may reduce future OUD risk. The aim of this study was to explore whether the onset of OUD is associated with preexisting mental health conditions such as anxiety and depressive disorders in young people. METHODS: A retrospective, population-based case-control study was conducted from 31 March 2018 until 01 January 2002. Provincial administrative health data were collected from Alberta, Canada. CASES: Individuals 18-25 years on 01 April 2018, with a previous record of OUD. CONTROLS: Individuals without OUD were matched to cases, on age/sex/index date. Conditional logistic regression analysis was used to control for additional covariates (e.g., alcohol-related disorders, psychotropic medications, opioid analgesics, and social/material deprivation). RESULTS: We identified N = 1848 cases and N = 7392 matched controls. After adjustment, OUD was associated with the following preexisting mental health conditions: Anxiety disorders, aOR = 2.53 (95% CI = 2.16-2.96); depressive disorders, aOR = 2.20 (95% CI = 1.80-2.70); alcohol-related disorders, aOR = 6.08 (95% CI, 4.86-7.61); anxiety and depressive disorders, aOR = 1.94 (95% CI = 1.56-2.40); anxiety and alcohol-related disorders, aOR = 5.22 (95% CI = 4.03-6.77); depressive and alcohol-related disorders, aOR = 6.47 (95% CI = 4.73-8.84); anxiety, depressive and alcohol-related disorders, aOR = 6.09 (95% CI = 4.41-8.42). DISCUSSION: Preexisting mental health conditions such as anxiety and depressive disorders are risk factors for future OUD in young people. Preexisting alcohol-related disorders showed the strongest association with future OUD and demonstrated an additive risk when concurrent with anxiety/depression. As not all plausible risk factors could be examined, more research is still needed.

Electronic harm reduction interventions for drug overdose monitoring and prevention: A scoping review.

BACKGROUND: Novel strategies are required to address rising overdose deaths across the globe. We sought to identify the breadth and depth of the existing evidence around electronic harm reduction (e-harm reduction) interventions that aimed to reduce the harms associated with substance use. METHODS: We conducted a scoping review according to the PRISMA-ScR and PRISMA for Searching guidelines. A health sciences librarian systematically searched seven health databases from inception until January 20, 2023. Citation chaining and reference lists of included studies were searched to identify additional articles. Two reviewers independently screened, extracted and charted the data. Additionally, we conducted a gray literature search and environmental scan to supplement the findings. RESULTS: A total of 51 studies met the criteria for inclusion (30 peer-reviewed articles and 21 non-peer reviewed). Most peer-reviewed studies were conducted in Western countries (USA = 23, Canada = 3, Europe = 3, China = 1) and among adult samples (adult = 27, youth/adults =1, unspecified = 2). Study designs were predominantly quantitative (n = 24), with a minority using qualitative (n = 4) or mixed methods (n = 2). Most e-harm reduction interventions were harm reduction (n = 15), followed by education (n = 6), treatment (n = 2), and combined/other approaches (n = 7). Interventions utilized web-based/mobile applications (n = 15), telephone/telehealth (n = 10), and other technology (n = 5). CONCLUSIONS: While e-harm reduction technology is promising, further research is required to establish the efficacy and effectiveness of these novel interventions.

Effects of Transcranial Direct Current Stimulation on Cognitive Deficits in Depression: A Systematic Review.

Background: Major depressive disorder is the leading cause of mental health-related burden globally and up to one-third of major depressive disorder patients never achieve remission. Transcranial Direct Current Stimulation is a non-invasive intervention used to treat individuals diagnosed with major depressive disorder and bipolar disorder. Since the last transcranial direct current stimulation review specifically focusing on cognitive symptoms in major depressive disorder, twice as many papers have been published. Methods: A systematic review was conducted with 5 electronic databases from database inception until March 21, 2022. Randomized controlled trials with at least 1 arm evaluating transcranial direct current stimulation in adults (diagnosed with major depressive disorder or bipolar disorder using the Diagnostic and Statistical Manual of Mental Disorders or International Classification of Diseases criteria) aged 18 or older were included. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were adopted. Results: : A total of 972 participants were included across 14 studies (60.5% female; mean age of 47.0 years [SD = 16.8]). Nine studies focused on participants with major depressive disorder and all studies used the Diagnostic and Statistical Manual of Mental Disorders to diagnose the participants. Seven out of the 14 studies showed significant improvements in at least 1 cognitive outcome measure in the active transcranial direct current stimulation group compared to the sham group. Several cognitive measures were used across studies, and 12 of the 14 studies reported mild-to-moderate side effects from treatment. Conclusion: : Current transcranial direct current stimulation literature has shown limited evidence for the treatment of cognitive impairments in major depressive disorder and bipolar disorder. Future research that applies machine learning algorithms may enable us to distinguish responders from non-responders, increasing clinical benefits of transcranial direct current stimulation.

Treatment options and shared decision-making in the treatment of opioid use disorder: A scoping review.

BACKGROUND: Shared decision-making (SDM) is an approach to clinical decision-making that includes patients' values and preferences during health-related decisions. Previous research suggests that SDM may be beneficial in the treatment of substance use disorders; however, the impact of SDM in the treatment of opioid use disorder (OUD) remains unclear. OBJECTIVES: To identify relevant peer-reviewed literature related to SDM in the treatment of adults with OUD, and to summarize the main findings according to patient outcomes. METHODS: The research team conducted a scoping review. The team searched five electronic health databases from database inception until September 2019 using MeSH and keywords related to SDM. The team included only peer-reviewed studies where adults (≥18 years) with OUD were provided a choice and/or allowed input into their treatment plan. Two independent reviewers screened, extracted, and assessed the quality of included studies. RESULTS: Fourteen studies (n = 1748 participants) met inclusion criteria, including seven randomized controlled trials, three non-randomized controlled trials, two observational studies, and one qualitative study. Treatment options included: patient regulated methadone dosing vs. fixed dosing (n = 4 studies), optional vs. mandatory counseling (n = 4 studies), home vs. office buprenorphine inductions (n = 2 studies), and inpatient vs. outpatient treatment (n = 1 study). None of the studies measured SDM with a validated instrument. Seven of 14 studies reported at least one improved patient outcome. CONCLUSIONS: The review found few studies that explored whether providing treatment options and/or encouraging participation in decision-making are beneficial for adults with OUD. Preliminary evidence suggests that SDM may be promising for this population. However, the field needs more research on person-centered care and SDM.

The adductor minimus muscle revisited.

The adductor minimus muscle has had scant and conflicting reports regarding its anatomy with some authors ignoring its existence altogether. The present study was conducted to more precisely describe the anatomy of this muscle. Forty human cadavers underwent dissection of the posterior thigh for observation of the adductor minimus muscle. When identified, this muscle was measured and relationships to the muscle documented. Additionally, five fetuses were dissected to observe for the presence of the adductor minimus muscle. The adductor minimus muscle was found in roughly one half of our specimens and was seen in all fetal specimens. When absent, the quadratus femoris muscle was always more prominent and extended more inferiorly toward the territory of the adductor minimus muscle. The average maximal length, width and thickness for the adductor minimus muscle was 14.6 cm, 7 cm, and 2.25 mm, respectively. Such data may be of consequence to clinicians who rehabilitate posterior thigh musculature or surgeons who operate this region.

Can the Anterolateral Ligament Be Reliably Identified in Anterior Cruciate Ligament-Intact and Anterior Cruciate Ligament-Injured Knees on 3-T Magnetic Resonance Imaging?

BACKGROUND: The anterolateral ligament (ALL) has been described as an extracapsular stabilizer of knee rotational stability. Investigators have shown a renewed interest in the ALL and further evaluated its anatomy and biomechanical role as a knee stabilizer. The appearance of the ALL on magnetic resonance imaging (MRI) remains inconsistent across the literature. PURPOSE: The aims of this study were 2-fold. The first objective was to further investigate the appearance of the uninjured ALL on MRI and provide data regarding interrater agreement in identifying the ligament. The second objective was to describe the incidence of concomitant ALL injuries in anterior cruciate ligament (ACL)-injured knees and provide data regarding interrater agreement in identifying and grading these injuries. STUDY DESIGN: Cohort study (diagnosis); Level of evidence, 3. METHODS: Fifty consecutive MRI scans of non-ACL-injured knees (control) and 50 consecutive MRI scans of ACL-injured knees performed at a single sports medicine center were identified. Three musculoskeletal radiologists independently reviewed the MRI scans in a randomized and blinded fashion. In the control group, the reviewers classified the ALL as visualized or not and did so for the proximal, middle, and distal thirds of the ligament. In the ACL tear group, the reviewers classified the ALL as visualized or not for each third of the ligament. They noted whether the ligament was injured and graded the injury as low, intermediate, or high. RESULTS: All 3 segments of the ALL were visualized in a mean 11% of patients. The ALL was partially visualized in a mean 68% of patients. The distal third of the ALL was injured 28% (14/50) of the time in the ACL tear group. The agreement rate among raters for classifying the injury status was fair to poor. CONCLUSION: Visualization of the ALL was inconsistent in the current study. Identifying and grading an injury to the ALL were difficult and had poor interobserver agreement. Using MRI to aid in the diagnosis of an ALL injury in the setting of an ACL tear is unreliable according to our study results. Further research looking at consistent ALL identification and injury patterns should be undertaken.

Patient engagement, treatment preferences and shared decision-making in the treatment of opioid use disorder in adults: a scoping review protocol.

INTRODUCTION: Opioid use disorder (OUD) is characterised by the fifth Edition of the Diagnostic and Statistics Manual as a problematic pattern of opioid use (eg, fentanyl, heroin, oxycodone) that leads to clinically significant impairment. OUD diagnoses have risen substantially over the last decade, and treatment services have struggled to meet the demand. Evidence suggests when patients with chronic illnesses are matched with their treatment preferences and engaged in shared decision-making (SDM), health outcomes may improve. However, it is not known whether SDM could impact outcomes in specific substance use disorders such as OUD. METHODS AND ANALYSIS: A scoping review will be conducted according to Arksey and O'Malley's framework and by recommendations from Levac et al. The search strategy was developed to retrieve relevant publications from database inception and June 2017. MEDLINE, EMBASE, PsycINFO, Cochrane Database for Controlled Trials, Cochrane Database for Systematic Reviews and reference lists of relevant articles and Google Scholar will be searched. Included studies must be composed of adults with a diagnosis of OUD, and investigate SDM or its constituent components. Experimental, quasi-experimental, qualitative, case-control, cohort studies and cross-sectional surveys will be included. Articles will be screened for final eligibility according to title and abstract, and then by full text. Two independent reviewers will screen excluded articles at each stage. A consultation phase with expert clinicians and policy-makers will be added to set the scope of the work, refine research questions, review the search strategy and identify additional relevant literature. Results will summarise whether SDM impacts health and patient-centred outcomes in OUD. ETHICS AND DISSEMINATION: Scoping review methodology is considered secondary analysis and does not require ethics approval. The final review will be submitted to a peer-reviewed journal, disseminated at relevant academic conferences and will be shared with policy-makers, patients and clinicians.

Utilization of Osseous Landmarks for Anatomic Anterior Cruciate Ligament Femoral Tunnel Placement.

Accurate placement of the femoral tunnel is critical for long-term clinical success following anterior cruciate ligament (ACL) reconstruction. The purpose of the present study is to evaluate the accuracy of femoral tunnel placement when referencing osseous landmarks during ACL reconstruction. We hypothesize that referencing osseous landmarks during ACL reconstruction consistently results in anatomic placement of the ACL femoral tunnel. This study was a retrospective case series. We reviewed 83 consecutive ACL reconstructions performed by a single surgeon. The lateral intercondylar ridge and lateral bifurcate ridge were referenced intraoperatively for anatomic placement of the ACL femoral tunnel during single-bundle reconstruction. Using these landmarks, the femoral tunnel was placed in the center of the anteromedial bundle footprint on the lateral wall of the intercondylar notch. We reviewed all operative notes and intraoperative arthroscopic images to assess tunnel placement. Postoperative anteroposterior and lateral radiographs were obtained in all patients. Anatomic placement was confirmed by review of lateral radiographs utilizing both the quadrant method (QM) and Blumensaat-ridge ratio (BRR). We used a total of 80 patients for our study. Review of arthroscopic images confirmed anatomic placement of the ACL femoral tunnel in all patients. All patients demonstrated that the femoral tunnel was placed anatomically according to the BRR method. Using the QM, all femoral tunnels were placed anatomically except for one tunnel that was placed slightly anteriorly. There was excellent agreement between the two radiographic measurement techniques. The principal finding of this study indicates that the lateral intercondylar ridge and the lateral bifurcate ridge are reliable landmarks for anatomic placement of the ACL femoral tunnel. Referencing osseous landmarks during surgery can help surgeons avoid nonanatomic placement of the ACL femoral tunnel, especially in cases where the soft-tissue footprint is no longer present. Furthermore, both the radiographic QM and the BRR are valid techniques to assess for anatomic ACL femoral tunnel placement both intraoperatively and postoperatively.

Outcomes After Arthroscopic Bankart Repair: Patients With First-Time Versus Recurrent Dislocations.

BACKGROUND: The young athletic population makes up the largest portion of shoulder instability and, when treated nonoperatively, has a recurrent dislocation rate as high as 71%. It is unknown how the outcomes of those who have a recurrent dislocation are affected versus those who have a stabilization procedure after a first-time dislocation. PURPOSE: To report the postoperative outcomes of patients with first-time dislocations versus patients with recurrent dislocations before surgery. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Current Procedural Terminology codes were used to identify patients who had arthroscopic Bankart repair between 2003 and 2013. A total of 173 eligible patients were identified across 8 fellowship-trained surgical practices. The first phase of the study was a retrospective chart review. Patients were identified as having a first-time dislocation or as having recurrent dislocations when they had >1 dislocation before surgical intervention. The second phase consisted of a survey to record a Simple Shoulder Test score and return to sport and to report postoperative instability and whether patients had further surgery on the shoulder. RESULTS: A total of 121 patients participated, providing 70% follow-up at an average of 51 months. There were 53 patients in the recurrent dislocation group and 68 in the first-time dislocation group. The postoperative instability rate was 29% in the first-time dislocation group and 62% in the recurrent dislocation group; this difference was significant ( P < .001). The odds of postoperative instability were 4 times higher in the recurrent dislocation group (odds ratio = 4.14). The first-time dislocation group reported a 7% rate of repeat operation to address instability, whereas the recurrent dislocation group reported a rate of 32%; this difference was significant ( P < .001). The odds of needing additional surgery on the index shoulder was 6 times higher in the recurrent dislocation group (odds ratio = 6.01). CONCLUSION: Patients with first-time dislocations had lower postoperative instability rates and reoperation rates when compared with patients with recurrent dislocations before surgery. Young patients with shoulder instability should be offered early surgical intervention to lower the risk of postoperative instability and reoperation.
