"Participation Is Fun and Empowering": A Participatory Approach to Co-Design a Cultural Art Program for Older Chinese at Risk of Depression in Hong Kong.

Background And Objectives: Internalized ageism and stigma of mental illness may disempower older people and impede help-seeking among those at risk of depression. Arts are deemed enjoyable, stigma-free, and conducive to mental health, and a participatory approach can engage and empower potential service users. This study aimed to co-design a cultural art program and test its feasibility in empowering older Chinese people in Hong Kong and preventing depression.

Radiographic Parameters of Adult Hip Dysplasia.

As knowledge about the origin and morphologic characteristics of hip pain in the young adult has evolved, so too has the clinician's ability to assess for various pathologies of the hip on radiographs, magnetic resonance imaging (MRI)/magnetic resonance arthrography (MRA), and computed tomography (CT). Because there is no algorithm at this time directly indicating what to do in more subtle hip morphologies, such as microinstability and borderline hip dysplasia (BHD), a skilled hip preservation specialist must use multiple imaging sources and know how to interpret them correctly. Imaging parameters used in the workup for hip dysplasia and BHD include the lateral center-edge angle, Tönnis angle, iliofemoral line, and presence of an upsloping lateral sourcil or everted labrum, among many others.

Pain Scores and Activity Tolerance in the Early Postoperative Period After Hip Arthroscopy.

Background: Despite the rapid growth in the use of hip arthroscopy, standardized data on postoperative pain scores and activity level are lacking.

Purpose: To quantify narcotic consumption and use of the stationary bicycle in the early postoperative period after hip arthroscopy.

Study Design: Case series; Level of evidence, 4.

Longitudinal versus transverse hip arthroscopy portal cosmesis: a case-control trial of simultaneous bilateral cases.

The direction and nature of incisions can impact the healing and appearance of a surgical scar. This can be attributed mainly due to skin tension and direction of force. The aim of this study was to identify differences in healing rates and scar esthetics between transverse and longitudinal portals used for hip arthroscopy.

The CU PAO: A Minimally Invasive, 2-Incision, Interlocking Periacetabular Osteotomy: Technique and Early Results.

Background: The aims of this study were to describe a novel minimally invasive, interlocking periacetabular osteotomy (PAO) for the treatment of hip dysplasia that was developed at our institution and to report on its safety, complications, and early clinical outcomes.

Methods: This was a prospective longitudinal study of the first 200 consecutive hips that underwent the CU (University of Colorado) PAO, an interlocking osteotomy combining the benefits of the Birmingham interlocking pelvic osteotomy (BIPO) and the Ganz PAO. The technique provides direct visualization of the sciatic nerve during the ischial osteotomy and allows for immediate weight-bearing postoperatively.

Distal Adductor Longus Avulsion: A Technique for Successful Repair.

Strains of the adductor muscle are common among athletes, but avulsion at its insertion is rare. Likewise, the diagnosis and management of distal ruptures of the adductors are infrequently reported in the literature. Presented here are the common presenting clinical findings of chronic distal adductor longus tendon ruptures and a description of how these can be successfully treated with a previously undescribed surgical technique.

Effects of Hip Arthroscopy Without a Perineal Post on Venous Blood Flow, Muscle Damage, Peripheral Nerve Conduction, and Perineal Injury: A Prospective Study.

Background: Prior reports of hip arthroscopy using a perineal post have established the risks of groin soft tissue injury, sexual dysfunction, and altered lower extremity neurovascular function. These parameters have not been investigated for hip arthroscopy without the use of a perineal post.

Purpose: To evaluate the effects of postless hip arthroscopy on lower extremity venous blood flow, nerve conduction, muscle tissue damage, and perineal injury.

The Effect of Green and Black Tea Polyphenols on Deficient Chinese Hamster Cells by Synthetic Lethality through PARP Inhibition.

Tea polyphenols are known antioxidants presenting health benefits due to their observed cellular activities. In this study, two tea polyphenols, epigallocatechin gallate, which is common in green tea, and theaflavin, which is common in black tea, were investigated for their PARP inhibitory activity and selective cytotoxicity to mutated cells. The observed cytotoxicity of these polyphenols to deficient cells is believed to be a result of PARP inhibition induced synthetic lethality.

Knee Cartilage Repair and Restoration: Common Problems and Solutions.

Focal cartilage defects in the knee are commonly found on MRI and arthroscopically. When these lesions are symptomatic and fail nonoperative management several surgical strategies are available. Common surgical techniques include reparative (ie, microfracture) and restorative procedures (ie, autologous chondrocyte implantation, particulated juvenile allograft cartilage, osteochondral autograft transfer, and osteochondral allograft).

Injury Recurrence Among High School Athletes in the United States: A Decade of Patterns and Trends, 2005-2006 Through 2015-2016.

Background: As participation in high school athletics increases, so does the number of adolescents experiencing sports-related injury. Understanding injury patterns is an important component to developing and evaluating prevention and rehabilitation programs.

Purpose: To analyze recurrent injury rates and patterns among high school athletes, to compare recurrent injuries with new injuries, and to evaluate injury trends over time.

Epidemiology of Injuries Sustained as a Result of Intentional Player Contact in High School Football, Ice Hockey, and Lacrosse: 2005-2006 Through 2015-2016.

Background: Lacrosse and ice hockey are quickly growing in popularity, while football remains the most popular sport among high school student-athletes. Injuries remain a concern, given the physical nature of these contact sports.

Purpose: To describe the rates and patterns of injuries sustained as a result of intentional player contact in United States high school boys' football, ice hockey, and lacrosse.

Current pain prescribing habits for common shoulder operations: a survey of the American Shoulder and Elbow Surgeons membership.

Background: Orthopedic surgeons are among the highest prescribers of narcotic pills, and no guidelines currently exist for appropriate management of postoperative pain within this field. The purpose of this study was to gain understanding of the current pain management strategies used perioperatively and postoperatively among orthopedic shoulder surgeons.

Methods: Members of the American Shoulder and Elbow Surgeons were e-mailed an online survey regarding methods for managing pain in the perioperative and postoperative setting for total shoulder arthroplasty, labral and capsular stabilization procedures, and rotator cuff repair.

MRI to Arthroscopy Correlations in SLAP Lesions and Long Head Biceps Pathology.

Superior labral anterior and posterior lesions and long head biceps injury are 2 common sources of shoulder pain. The presenting complaints and physical examination findings for these etiologies are often nonspecific, making diagnosis challenging. Further complicating their diagnoses, these 2 pathologies often cooccur together or with other shoulder pathologies such as subacromial bursitis, rotator cuff tear, and shoulder instability.

The Iliofemoral Line: A Radiographic Sign of Acetabular Dysplasia in the Adult Hip.

Background: Several radiographic parameters utilized for the diagnosis of acetabular dysplasia in adults suffer from poor reproducibility and reliability.

Purpose: To define and validate a novel radiographic parameter (the iliofemoral line [IFL]) for the detection of frank and borderline hip dysplasia and to compare the sensitivity and specificity of this radiographic marker to those of previously validated qualitative parameters.

Study Design: Cohort study (diagnosis); Level of evidence, 2.

Current Concepts of the Anterolateral Ligament of the Knee: Anatomy, Biomechanics, and Reconstruction.

In 1879, Paul Segond described an avulsion fracture (now known as a Segond fracture) at the anterolateral proximal tibia with the presence of a fibrous band at the location of this fracture. Although references to this ligament were occasionally made in the anatomy literature after Segond's discovery, it was not until 2012 that Vincent et al named this ligament what we know it as today, the anterolateral ligament (ALL) of the knee. The ALL originates near the lateral epicondyle of the distal femur and inserts on the proximal tibia near Gerdy's tubercle.

Proportion of Obese Patients Presenting to Orthopedic Total Joint Arthroplasty Clinics.

The purpose of this study is to demonstrate that the percentage of obese individuals initially presenting to total joint arthroplasty clinics in a public, tertiary hospital is greater than the proportion of obese individuals in the general population. In a retrospective, comparative study of patients seen in total joint replacement clinics at a public, tertiary hospital with an ICD-9 diagnosis of hip or knee osteoarthritis and documented body mass index, the proportion of obese individuals was compared with recent obesity data for the general population from the Centers for Disease Control and Prevention. Patients who had previously undergone hip or knee replacement surgery were excluded.

A Comprehensive Analysis of Replicative Lifespan in 4,698 Single-Gene Deletion Strains Uncovers Conserved Mechanisms of Aging.

Many genes that affect replicative lifespan (RLS) in the budding yeast Saccharomyces cerevisiae also affect aging in other organisms such as C. elegans and M. musculus.

Patient impressions of reimbursement for orthopedic spine surgeons.

The study aim was to understand patient impressions of reimbursement to orthopedic spine surgeons. Our findings revealed that the majority of patients significantly overestimate the amount surgeons are reimbursed per procedure. Despite this, most feel that surgeons are appropriately compensated.

A-type nuclear lamins act as transcriptional repressors when targeted to promoters.

Regions of heterochromatin are often found at the periphery of the mammalian nucleus, juxtaposed to the nuclear lamina. Genes in these regions are likely maintained in a transcriptionally silent state, although other locations at the nuclear periphery associated with nuclear pores are sites of active transcription. As primary components of the nuclear lamina, A- and B-type nuclear lamins are intermediate filament proteins that interact with DNA, histones and known transcriptional repressors, leading to speculation that they may promote establishment of repressive domains.
