Abstract Introduction: The American Medical Association recommends that healthcare articles intended for the public should be written at or below a sixth grade reading level. literature has consistently shown online materials on orthopedic surgeries are level well above this threshold. This discrepancy can exacerbate existing disparities, as patients with lower education language barriers may unable to fully understand implications of surgical procedure and postoperative protocol. study...

This study seeks to evaluate the epidemiology of pickleball upper/lower extremity injuries presenting US emergency departments (E.D). The National Electronic Injury and Surveillance System (NEISS) database was queried from 2003-2022 identify patients ED with sustained during 'pickleball' extremities. Patients were subsequently divided into pediatric, adult, geriatric age groups. Demographic clinical variables assessed among groups utilizing two-proportion z-tests Bonferroni correction. A...

<h2>Abstract</h2><h3>Background</h3> A shift toward performance, cost, outcomes, and patient satisfaction has occurred with healthcare reform promoting value-based programs. The purpose of this study was to evaluate the relationship between value treatment in a cohort patients undergoing total knee arthroplasty (TKA) hip (THA). <h3>Methods</h3> Value determined by outcome episodic cost. Measurements included both clinical outcomes patient-reported outcomes. Participating surgeons took part...

The supraspinatus is most frequently involved in rotator cuff tears, a common orthopaedic condition. However, the architecture of this muscle has been described only for superficial, anterior, and posterior regions.

Cycling is known to cause groin pain, typically adductor/hamstring strains and "saddle sores" (skin abrasion, ulceration and/or folliculitis). Rarely does it result in pathological mesenchymal lesions. We report a case of 52-year-old female avid cyclist with chronic pain. Activity alteration, bike fit, saddle modification did not ameliorate her symptoms. MRI revealed no hamstring or bony abnormality but demonstrated low T1/high T2 signal the right perineum inferior ischial tuberosity....

We introduce an improved method to assess rabbit supraspinatus muscle physiology. Maximum isometric force measured for the was dramatically greater than previous reports in literature. Consequently, contractile stress reported is almost 10 times of supraspinatus, but similar available literature other mammalian skeletal muscle. show that peak were subphysiological by ∼90%

Introduction Despite the prevalence of corticosteroid injections in athletes, little is known about their efficacy triathletes. We aim to assess attitudes, use, subjective effectiveness, and time return sport with compared alternative methods triathletes knee pain. Methods This an observational study during COVID-19 pandemic. Triathletes answered a 13-question survey posted three triathlon-specific websites. Results Sixty-one responded, 97% whom experienced pain at some point triathlete...

Case: A 31-year-old male sustained acute compartment syndrome to his left leg after a low-energy fall and required 4-compartment fasciotomy release. His immediate postoperative course was complicated by tubular necrosis (ATN) with creatinine elevated 4.89 mg/dL from rhabdomyolysis. ATN managed aggressive hydration, sodium bicarbonate, alkaline diuresis, levels improved. Conclusions: rhabdomyolysis is rare complication of that requires high suspicion timely treatment prevent further...

Chronic rotator cuff tears can cause severe functional deficits. Addressing the chronic fatty and fibrotic muscle changes is of high clinical interest; however, architectural physiological consequences tear repair are poorly characterized. We present a detailed analysis (both over 8 16 wk) compared with age-matched control rabbit supraspinatus (SSP) muscles. Using female New Zealand White Rabbits (

Case: A 16-year-old woman presented with acute on chronic knee pain and instability following a twisting injury. The tibial insertion of the anterior cruciate ligament (ACL) was nonvisualized magnetic resonance imaging. cord-like ACL, originating from lateral intercondylar notch inserting smoothly into horn intact meniscus, found arthroscopy. Her ACL reconstructed quadriceps tendon autograft. Conclusion: We report rare case dysplastic meniscus in patient without obvious skeletal deformities....

Objectives: The supraspinatus (SSP) tendon is the most frequently involved in rotator cuff tears, a common orthopedic condition. Previous anatomical studies have described distinct anterior and posterior regions of SSP muscle. purpose this study to determine if deep region muscle has significantly different architectural properties from other regions. This could implications on mechanical functional nature Methods: Architecture measurements were collected 25 cadaver SSPs (Figure 1). There 13...
