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

Title: Comparative Effectiveness of Liposomal Bupivacaine and Regional Nerve Blocks for Analgesia After Total Knee Arthroplasty
Introduction: Liposomal bupivacaine (Exparel) has been adopted in total knee arthroplasty (TKA) as a long-acting local anesthetic. However, its comparative effectiveness against standard regional anesthesia techniques, such as femoral or adductor canal block, remains insufficiently defined. This study evaluates postoperative analgesic utilization following TKA among patients receiving Exparel, regional blocks, or no regional intervention, using matched cohorts from a large national dataset.
Methods: Patients who underwent primary TKA between January 1, 2005 and January 1, 2025 were retrospectively identified from a multi-institutional electronic medical …

Periprosthetic joint infection (PJI) can present challenges in diagnosis and treatment, particularly in the setting of atypical causative organisms such as fungi and mycobacteria. Herein, we present a case and provide a review of the diagnosis and treatment of an unusual PJI caused by bacillus Calmette-Guérin, administered during the treatment of bladder cancer 3 years prior to total knee arthroplasty and subsequent PJI. Although the patient's history of bladder cancer was known, neither his Bacillus Calmette-Guérin treatment nor its potential for distant site spread that could lead to PJI were appreciated, leading to a prolonged diagnostic evaluation and treatment course.

Total knee arthroplasty (TKA) is the final treatment option for patients with advanced knee osteoarthritis (OA). Unfortunately, TKA surgery is accompanied by acute postoperative pain that is more severe than arthroplasty performed in other joints. Elucidating the molecular mechanisms specific to post-TKA pain necessitates an animal model that replicates clinical TKA procedures, induces acute postoperative pain, and leads to complete functional recovery. Here, we present a new preclinical TKA model in rats and report on functional and behavioral outcomes indicative of pain, analgesic efficacy, serum cytokine levels, and dorsal root ganglia (DRG) transcriptomes during the acute postoperative period. Following TKA, …

Recurrent Hemarthrosis Secondary To Erosive Patellofemoral Arthritis Treated With Arthroplasty: A Report Of 3 Cases, Rachael A. Turner, Justin N. Duke, Trevor G. Murray, Jared R.H. Foran
Research Symposium
Background: Spontaneous hemarthrosis of the knee joint in the elderly population is a rare phenomenon and is mostly seen in those with osteoarthritis. The identified causes of spontaneous hemarthrosis in this demographic include subchondral bone bleeding, meniscal tear, genicular artery bleeding, and the use of anticoagulants. Hemarthrosis caused by isolated patellofemoral bleeding, as in this case series, has been rarely documented and poorly described.
Case: Three patients presented with recurrent hemarthrosis secondary to erosive patellofemoral arthritis. Recurrent hemarthrosis from the eroded patellofemoral subchondral bone has not been well described. Each patient presented with symptoms secondary to painful effusions that …

Giardia Lamblia Reactive Arthritis Mimicking Acute Periprosthetic Knee Infection: A Case Report, Rachael A. Turner, Justin N. Duke, Jared R.H. Foran
Research Symposium
Background: The difficulty in diagnosing Periprosthetic joint infection (PJI) is exacerbated by the more varied presentation of PJI and the lower synovial fluid WBC count thresholds applied when a prosthesis is present. Multiple reports have described pseudosepsis after total knee arthroplasty (TKA) due to gout or pseudogout. Further confusing the picture, periprosthetic infection also frequently coexists with crystalline arthropathy. Our review of the literature revealed no reports describing reactive arthritis (ReA) mimicking acute infection in the setting of previous TKA. In this case report, we describe a pseudo-periprosthetic infection of a well-functioning TKA secondary to ReA in the setting of …

Purpose: Modern multimodal analgesia has been shown to significantly reduce opioid use following total knee arthroplasty (TKA). This study was conducted to determine if changing TKA discharge opioid prescriptions from automatic to upon request resulted in more opioid free recoveries without compromising pain control. Methods: Between December 2019 and August 2021, an orthopedic surgeon performed 144 primary unilateral TKAs; patients received the same multimodal analgesia protocol except for postoperative opioid prescribing. The first consecutively-treated cohort automatically received an opioid prescription following discharge (automatic group) and the second cohort received opioid prescriptions only upon request (upon request group). Opioid prescription data …

Orthopedic Surgery Resident Research
This paper is a comprehensive review that describes indications, contraindications, clinical outcomes, and pearls and pitfalls of 1.5-stage revision total knee arthroplasty (TKA) utilizing a primary TKA femoral component, all-polyethylene tibial component, and hand-crafted antibiotic cement for the management of chronic periprosthetic joint infection. The 1.5-stage exchange TKA details placement of an articulating spacer for an indefinite period, prolonging revision until reinfection, deterioration of functional status, or construct failure. A 1.5-stage revision TKA technique is a viable option for treatment of chronic periprosthetic knee infections. The inherent advantages of decreased health-care costs, decreased morbidity and mortality, and improved emotional ease …

The Outcomes Of Cemented Versus Cementless Total Knee Arthroplasty In Modern Day Patients With Osteoarthritis, Jordan Powelson
Capstone Showcase
Osteoarthritis (OA), the degeneration of cartilage and bone, is the most progressive musculoskeletal disease and a leading cause of disability in the United States, affecting over 27 million adults. Although conservative treatments for knee OA are available, total knee arthroplasty (TKA) is the only definitive treatment for end-stage knee OA. For the past several decades, the use of bone cement has been the gold standard for total knee arthroplasty, but the cementless TKA is being revisited as an option as the age of patients seeking TKA decreases and the average BMI increases. This review analyzes and compares the outcomes of …

Increased Use Of Opioids Perioperatively Leads To Unmanaged Postoperative Pain, Halida Sehic
Nursing | Senior Theses
Background: Total knee and total hip joint arthroplasty are two frequently preformed surgeries, with 5.2 million total knee arthroplasties performed the United States between the year 2000 and 2010 (Williams et al., 2015). Opioids are widely used to manage pain for patients undergoing total joint arthroplasty. However, use of opioids is associated with undesirable adverse effects, such as nausea and respiratory depression, (Johnson et al., 2011). In postoperative patients following total joint replacement, 75 % of the patients complain of inadequately controlled moderate to severe pain (De Luca et al., 2018). Increased use and overprescribing increase tolerance to opioids …

Orthopaedic Surgery and Sports Medicine Faculty Publications
Background: Several studies have reported lower perioperative complications with unicompartmental knee arthroplasty (UKA) than with total knee arthroplasty (TKA). However, there is a paucity of data analyzing the incidence of periprosthetic joint infection (PJI) in similar patients undergoing UKA and TKA. As such, we sought to analyze the incidence of UKA and TKA PJI in a large matched population.
Material and Methods: The Mariner data set of the PearlDiver database was queried for all patients undergoing UKA or TKA during 2010-2017. Included patients were required to have at least 2 years of database inclusion after surgery. Patients were then matched …
