Optimizing Total Knee Arthroplasty In Young Patients: Strategies For Enhancing Durability And Function, Bridger Bell

Bone Bulletin

Introduction

The subspecialty of orthopaedics focuses on the prevention, diagnosis, and treatment of diseases and injuries impacting the musculoskeletal system.1 Within orthopaedics, surgery for arthritis and related conditions make up half of those performed.² Of the surgical interventions for arthritis, total knee arthroplasty (TKA) is one of the most frequent, with over 700,000 performed per year in the United States and an expectation that nearly one million will be performed by 2030.3 Interestingly, since the 1980s, the prevalence of surgery in younger patients has continually increased.⁴ This has been accompanied by a declining average age of primary TKA …

Hazards For The Female Athlete: Disparities In Acl Injury Risk And The Evolving Research Base, Abby Skiena

Bone Bulletin

Introduction

Sex plays a significant role in sports medicine risk factors, but historically, there has been a lack of research involving female participants and investigating physiologic factors unique to female athletes.^1–4 Male athletes face a 2.26 times higher risk of hip and groin injuries, a 2.4 times higher risk of hamstring injuries, and a 1.8-2.8 times higher risk of acute fractures, especially in competitive situations.² Alternatively, female athletes experience a 2-8 times higher rate of anterior cruciate ligament (ACL) injuries, a 3.4 times higher risk of bone stress injuries, a 1.25 times higher rate of foot and ankle …

Outcomes In Robotic Knee Surgery, Tyler West

Bone Bulletin

Introduction

Total knee arthroplasty (TKA) is one of the most common orthopedic surgeries worldwide and is the mainstay for treating severe knee arthritis. In the United States, surgeons perform over 700,000 TKAs each year, and that number is expected to climb as osteoarthritis becomes more common in an aging population.^1,2 Roughly, two TKAs are completed for every one total hip arthroplasty (THA) and yet patient satisfaction after TKA has always lagged behind the THA.³ Hip replacements routinely see satisfaction rates above 90 percent.^2,3 For knees, however, satisfaction rates historically have fallen between 80 and 89 percent.^{4 …}

Conceptual Frameworks, Evolving Technology, And Common Misconceptions: How Orthopedic Hand Surgeons Choose Fracture Fixation Technique, Sudesh Jaisi

Bone Bulletin

Fracture fixation is often taught as a binary decision between operative and nonoperative management, which fails to reflect the complexity of real-world clinical decision-making. This article analyzes fracture fixation through a conceptual, fracture personality-based framework incorporating biomechanics, fracture characteristics, patient-specific factors, and evolving implant technology. Clinical decision-making is best understood as a spectrum of interventions, where multiple fixation strategies may be technically appropriate but differ in invasiveness, stability, complication risk, and functional recovery. Across representative fracture types, including distal radius and olecranon injuries, management is driven by fracture stability, anticipated behavior under physiologic load, and patient functional demands rather than …

Unicompartmental Versus Total Knee Arthroplasty In Osteoarthritis: Indications, Outcomes, And Value-Based Care, Spencer Uggla

Bone Bulletin

Introduction

Knee osteoarthritis (OA) is a highly prevalent and disabling condition, affecting an estimated 654 million people worldwide in 2023. It is the most common diagnosis among patients over 45 years of age who present with activity-related knee pain.1 When nonoperative management fails, surgical intervention is frequently required to relieve pain and restore function. Traditionally, total knee arthroplasty (TKA) has been considered the gold standard surgical treatment for advanced OA, with approximately 700,000 procedures performed annually and projections exceeding 1 million by 2030.²

The Impact Of Wide-Awake Local Anesthesia No Tourniquet Surgery On Distal Radius Fracture Plating, Michael Carey

Bone Bulletin

Introduction

The surgical technique known as wideawake local anesthesia no tourniquet (WALANT) has been widely used in soft tissue hand procedures since 2005.1 A local surgical field block using lidocaine with epinephrine provides local anesthesia and hemostasis via alpha-1 adrenergic agonism without the need for general anesthesia with a tourniquet. In addition to reducing costs related to general anesthesia (GA), WALANT procedures are suitable for American Society of Anesthesiologists Physical Status Classification 4 (ASA 4) high-risk patients, specifically by eliminating anesthesia risks such as nausea, aspiration, pneumonia, and thromboembolism, all while maintaining or improving clinical outcomes compared with the current …

Suture-Free Nerve Repair In Upper-Extremity Surgery, Adam Gaughan

Bone Bulletin

Introduction

Peripheral nerves have a limited capacity to regenerate.¹ Treating peripheral nerve injuries and the ensuing recovery of sensory and/or motor function are challenging for surgeons due to a number of variables that impact nerve recovery; including, the mechanism of nerve transection, the level or distance of injury relative to the target organ, patient age and comorbidities, and the repair technique employed. Most factors are not modifiable, but repair techniques are modifiable and can have a meaningful impact on outcomes. Nerve repair opt ions inc lude di r e ct end- to- end r epai r (neurorrhaphy), conduit-assisted repair, …

Scalpel To Robot To Algorithm: Robotics, Artificial Intelligence, And The Evolution Of Spine Surgery, Mateja Stefanovic

Bone Bulletin

Introduction

The past five decades in spine surgery have seen innovations in pedicle screw fixation, image-guided navigation, and first-generation robotics; each change was confronted with skepticism for uprooting existing paradigms until pushback inevitably yielded progress. Artificial intelligence (AI) and machine learning (ML) feel different in kind. Beyond better instrumentation, they represent entirely new frameworks for processing clinical information at unprecedented scale and speed. A neural network trained on thousands of preoperative records can learn to detect interactions among imaging findings, laboratory indices, functional variables, and comorbidity burden that conventional statistical models are structurally unable to identify.¹˒² Simultaneously, robotic platforms outfitted …

The Changing Value Of Joint Arthroplasty Under The Rvu System, Kiley Hamou

Bone Bulletin

Background and Introduction of Total Knee Arthroplasty

Few procedures in modern medicine illustrate the value of surgical advancement more clearly than total hip and total knee arthroplasty. Over the past several decades, advances in surgical technique, pre-operative management, and postoperative rehabilitation have transformed joint replacement into one of the most successful procedures in medicine. Patient satisfaction rates routinely exceed 90% and millions of individuals regain mobility, independence and quality of life each year through these operations.¹ However, despite this clinical success and societal value, physician reimbursement for joint replacement surgery and many other successful orthopedic procedures has steadily declined. …

Clinical Uncertainty In Digital Monitoring After Shoulder Arthroplasty, Abhimaneu Pandey

Bone Bulletin

Introduction

Wearable sensor technology and smartphone based care platforms have been identified as promising technologies for postoperative care after joint arthroplasties.^1,2 In fact, in lower extremity arthroplasty, these technologies have already demonstrated their effectiveness in a multitude of randomized trials.^1,2 One recent multicenter RCT with 401 patients undergoing primary total knee arthroplasty (TKA) showed that self-directed rehabilitation using a smartwatch and mobile application (mymobility with Apple Watch, Zimmer Biomet) achieved comparable range of motion and patient-reported outcomes measures (PROMs) to standard post-operative rehab without increasing adverse events.¹ Related evidence also indicates that “episode of care” smartphone applications …

The Thai Journal of Veterinary Medicine

Birth weight (BW) is a key determinant of average daily gain (ADG) in piglets; however, hyperprolific sow genetics, particularly under tropical conditions, have increased the proportion of low-birth-weight piglets. This study evaluated factors associated with ADG during the first 7 days of lactation within birth weight categories (1.3 kg). A total of 1,185 piglets from 97 litters that survived to day 7 were included. Factors analyzed were cumulative birth interval, birth order, colostrum intake per kilogram of body weight, rectal temperature at 24 h postpartum, sex, intrauterine growth restriction (IUGR), and cross-fostering. Birth weight, cumulative birth interval, birth order, colostrum …

Adult-Onset Iga Vasculitis Initially Attributed To A Cutaneous Drug Reaction And Diverticulitis, Leila C. Tou, Catherine Grace P. Hobayan, Shane Devine, Sarah Koraym

Journal of Community Hospital Internal Medicine Perspectives

Immunoglobulin A vasculitis (IgAV), formerly Henoch–Schönlein purpura, is a small-vessel vasculitis characterized by palpable purpura, arthralgias, gastrointestinal involvement, and renal disease. Although IgAV is common in children, adult-onset disease is rare and may be associated with more severe manifestations, particularly renal involvement. In adults, IgAV may be difficult to recognize because of overlap with more common gastrointestinal, infectious, or medication-related conditions. We present a case of adult-onset IgAV initially attributed to presumed diverticulitis and later to a drug eruption following antibiotic exposure. This case highlights diagnostic pitfalls and the importance of early recognition and renal surveillance.

Rare Presentation Of Sequential Mucosa-Associated Lymphoid Tissue Lymphoma, Follicular Lymphoma, And Chronic Lymphocytic Leukemia: A Case-Based Review, Khushi J. Desai, Ansy H. Patel, Patrick T. O’Dowd, Joseph A. Tworek, Preeti G. Misra, Li Ding

Journal of Community Hospital Internal Medicine Perspectives

Overcoming Igf1r-Mediated Resistance To Oncolytic Hsv1 And Radiotherapy Via Triple Combination Therapy, Alexandra A Miller, Min-Hye Noh, Jin Muk Kang, Jiyeon Kim, Lily Nguyen, Amanda S Kouaho, Grace Nguyen, Minxin Huang, Stephanie M Bean, Joshua Davis, Matthew P Mullarkey, Sunil Krishnan, Zhongming Zhao, E Antonio Chiocca, Tae Jin Lee, Ji Young Yoo

The Brown Foundation: Institute of Molecular Medicine

FDA-approved oncolytic herpes simplex virus-1 (oHSV) therapy has emerged as a promising viro-immunotherapy for solid tumors. However, tumor- and tumor microenvironment (TME)-associated adaptations following viral treatment, such as feedback immune suppression, neoangiogenesis, and enhanced tumor aggressiveness, often hinder complete tumor eradication. A deeper understanding of the molecular mechanisms underlying resistance to oHSV is crucial to enhancing its clinical impact. We recently discovered that oHSV induces Insulin-like growth factor 2 (IGF2) secretion, shaping an immunosuppressive TME. Similarly, radiotherapy (RTx) activates the IGF1/IGF1R and YAP1 signaling pathways, further promoting therapeutic resistance. In this study, we investigated how oHSV-induced Insulin-like growth factor 1 …
