Inferior Clinical Outcomes Following Endoscopic Proximal Hamstring Repair in Patients With Chronic Degenerative Tears Despite the Use of Dermal Allograft Augmentation.

Purpose: To compare clinical outcomes in patients undergoing endoscopic proximal hamstring repair with and without dermal allograft augmentation.

Methods: A retrospective review of prospectively collected data was performed on patients undergoing endoscopic proximal hamstring repair (PHR) and proximal hamstring repair with dermal allograft augmentation (PHR-A) by a single surgeon between 2016 and 2023. Augmentation was utilized for cases of chronic degenerative tears (≥6 weeks from the time of initial injury) where hamstring tissue quality was deemed poor intraoperatively.

Comparable Pain Levels and Functional Outcomes With and Without the Use of Dermal Allograft Augmentation in Endoscopic Gluteus Medius Repair.

Purpose: To compare retrospectively the clinical outcomes of patients undergoing endoscopic gluteal tendon repair with and without the use of dermal allograft augmentation.

Methods: A retrospective review of prospectively collected data, single-surgeon cohort study was performed on all patients undergoing endoscopic gluteus medius repair (GMR) and GMR with augmentation (GMR-A) between April 2017 and April 2022.

Inadequate Performance of ChatGPT on Orthopedic Board-Style Written Exams.

Background: Chat Generative Pre-Trained Transformer (ChatGPT) is an artificial intelligence (AI) chatbot capable of delivering human-like responses to a seemingly infinite number of inquiries. For the technology to perform certain healthcare-related tasks or act as a study aid, the technology should have up-to-date knowledge and the ability to reason through medical information. The purpose of this study was to assess the orthopedic knowledge and reasoning ability of ChatGPT by querying it with orthopedic board-style questions.

ChatGPT Is Moderately Accurate in Providing a General Overview of Orthopaedic Conditions.

Background: ChatGPT is an artificial intelligence chatbot capable of providing human-like responses for virtually every possible inquiry. This advancement has provoked public interest regarding the use of ChatGPT, including in health care. The purpose of the present study was to investigate the quantity and accuracy of ChatGPT outputs for general patient-focused inquiries regarding 40 orthopaedic conditions.

Robotic Abdominal Wall Repair with Endoscopic Adductor Lengthening: A Minimally Invasive Approach for Core Muscle Injuries.

Groin pain is a common complaint in sports medicine practices but can be a challenge to accurately diagnose given the expanse of differentials. In the athlete, groin pain may be caused by a core muscle injury, also known as sports hernia or athletic pubalgia. These injuries most frequently occur in young males who participate in explosive and rotationally demanding activities such as soccer, football, and ice hockey, which generate large forces across the trunk and hip joint.

Editorial Commentary: For Surgical Treatment of Elbow Lateral Epicondylitis, Arthroscopic Treatment Is Recommended for Surgeons With Elbow Arthroscopy Training.

Lateral epicondylitis is a commonly encountered and persistent problem in the active, middle-aged population, with a reported annual incidence as high as 3.4%. Lateral epicondylitis is often treated successfully with conservative measures but may necessitate surgical intervention in refractory cases.

Current Trends in the Use of Postless Hip Arthroscopy: A Survey of the International Society for Hip Arthroscopy Membership.

Erdheim-Chester disease presenting at the central nervous system.

Erdheim-Chester disease is a rare non-Langerhans cell histiocytosis (LCH) that affects different body systems. It was recently recognized as a neoplastic disorder after identifying an activating mutation of the MAPK pathway. Neurological presentations of ECD are rare.

Pancreatic cancer presenting with pulmonary cannonball lesions.

Cannonball lesions are numerous, well-circumscribed, round pulmonary lesions and may be identified on plain radiograph or advanced imaging. This morphology can be associated with infectious causes, rheumatologic disease and metastatic disease. Classically, when cannonball lesions are associated with metastatic disease, they are seen in renal cell carcinoma and choriocarcinoma.

Lytic Bone Lesion: An Unusual Presentation of Hairy Cell Leukemia.

Hairy cell leukemia (HCL) is a seldom encountered malignancy of lymphocytes with a low incidence in the United States. HCL generally follows an indolent course and not all patients require treatment. Most patients are asymptomatic at the time of diagnosis.

COVID-19 Induced Bilateral Lower Limb Ischemia and Visceral Infarcts.

Emerging cases of coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) have been associated with a variety of disorders including respiratory failure, immune reactive syndrome, multiorgan failure, and hypercoagulable states. COVID-19 induces a severe global inflammatory response which can result in endothelial damage leading to hypercoagulability. Most COVID-19 cases of hypercoagulable states reported venous thrombosis.

Patients recall worse preoperative pain after shoulder arthroplasty than originally reported: a study of recall accuracy using the American Shoulder and Elbow Surgeons score.

Background: Patient-reported outcome measures (PROMs) are valuable tools for quantifying outcomes of orthopedic surgery. However, when baseline scores are not obtained, there is considerable controversy about whether PROMs can be administered retrospectively for patients to recall their preoperative state. We investigated the accuracy of patient recall after total shoulder arthroplasty (TSA) using the American Shoulder and Elbow Surgeons (ASES) assessment score.

Anatomic total shoulder arthroplasty for patients receiving workers' compensation.

Background: Studies have demonstrated that receiving workers' compensation (WC) benefits can be a negative predictor of outcomes after orthopedic procedures. This study compares postoperative outcomes of anatomic total shoulder arthroplasty (TSA) between patients receiving WC benefits and a control group that did not.

Methods: A cohort of 13 consecutive TSA patients with WC benefits were compared with a control group of 63 consecutive patients with a minimum of 2 years of follow-up during the same period.
