Department of Medicine Faculty Papers

BACKGROUND: Rates of total knee arthroplasty (TKA) in the United States have risen in patients of a wide age range. Although rates of postoperative TKA complications have decreased, they remain a significant concern. In this study, we aim to determine how the risk of adverse TKA outcomes changes dynamically with age and explore the optimal ages with the lowest risk for adverse outcomes.

METHODS: This retrospective cohort study included patients who underwent elective primary TKA from 2012 to 2018 in the Pennsylvania Health Care Cost Containment Council Database. We trained (70% train:30% test) an explainable boosting machine (EBM), a modern …

North Texas GME Research Forum 2026

Introduction Intraoperative and postoperative blood loss is a major concern and challenge for surgeons in total joint arthroplasty (TJA). Patients with large blood loss can develop postoperative anemia and associated complications. Novel hemostatic agents, such as oxidized regenerated cellulose (ORC) have grown in popularity as intraoperative hemostatic adjuncts. The aim of this systematic review and meta-analysis is to evaluate the efficacy of ORC for intraoperative and postoperative blood loss.

Utilizing Femoral Metaphyseal Sleeves In Primary Total Knee Arthroplasty For Post-Traumatic Osteoarthritis: A Case Report, Zachary Sukin, Adam Dentinger, Jeremiah Earl

HCA Healthcare Journal of Medicine

Background

Total knee arthroplasty in younger patients presents a heightened risk of postoperative complications and implant failures compared to older populations, particularly in those with posttraumatic arthritis. These challenges necessitate careful consideration and specialized approaches to optimize the outcomes in this patient demographic.

Case Presentation

A 43-year-old man presented with left knee pain resulting from a traumatic lawn mower injury, causing an intraarticular distal femur, at the age of 6. The injury led to a limb-length discrepancy for which he underwent 2 limb-lengthening procedures in his early 20s. Radiographs demonstrated advanced posttraumatic osteoarthritis, and the patient elected to proceed with …

Rethinking Pain Relief After Surgery: What We Can Learn From Knee Replacements, Asim Trimzi

SKMC Student Presentations and Publications

This paper offers a clear, evidence-based look at how we can reduce opioid use after knee replacement surgery without sacrificing pain relief. This review focuses specifically on total knee arthroplasty (TKA)-one of the most commonly performed and most painful surgeries-and asks whether opioids are truly necessary. By analyzing results from 21 clinical trials, the paper shows that non-opioid medications like NSAIDs and gabapentinoids can provide similar pain control with fewer side effects, such as nausea, dizziness, constipation, and sedation. Lower risk of long-term use is an added benefit. A recent RCT found that after knee/shoulder arthroscopy, 72% of patients in …

In-Hospital Exposure And Opioids Prescribed After Total Knee Arthroplasty, Clifton Daigle, Robert Branstetter, Leland Van Deventer, Ravi Rajendra, Claudia Leonardi, Amy Bronstone, Vinod Dasa

School of Medicine Faculty Publications

BACKGROUND: Opioids are frequently used intraoperatively and during postanesthesia care unit care in total knee arthroplasty (TKA) cases and are commonly prescribed after surgery despite known adverse effects. This study examined whether in-hospital opioid exposure is related to postoperative opioid prescribing in opioid-naïve TKA patients. METHODS: This retrospective study included opioid-naïve patients (no opioid prescriptions filled during the three months before TKA) who had unilateral primary TKA between May 1, 2020, and November 30, 2023, performed by an orthopaedic surgeon. All patients were treated using the same multimodal pain protocol. Opioid prescriptions filled by patients during the three months following …

BACKGROUND: This article examines predictors of subsequent total knee arthroplasty (TKA) within 6 months of nonoperative intervention based on (1) patient demographics; (2) knee osteoarthritis (OA) severity; and (3) various nonoperative treatments (cryoneurolysis with superficial or deep genicular nerve block, intra-articular [IA] hyaluronic acid injections, nonsteroidal inflammatory drug injections, IA-corticosteroids injections, or IA-triamcinolone extended-release [IA-TA-ER] injections). METHODS: Patients who had unilateral knee OA and received nonoperative intervention were identified in the Innovations in Genicular Outcomes Research registry between September 2021 and February 2024, identifying 505 patients. Baseline patient demographics were tabulated by knee OA severity as graded by Kellgren-Lawrence (KL) …

A Modern Multimodal Pain Protocol Eliminates The Need For Opioids For Most Patients Following Total Knee Arthroplasty: Results From A Retrospective Comparative Cohort Study, Leland Van Deventer, Amy Bronstone, Claudia Leonardi, Matthew Bennett, Peter Yager, Vinod Dasa

School of Medicine Faculty Publications

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 …

Failure Of Primary Total Knee Arthroplasty: Establishing A Baseline For Retrieval Analysis Using Well-Functioning Necropsy Specimens, Meredith Perkins

Theses and Dissertations (ETD)

Introduction. Total knee arthroplasty (TKA) is an effective treatment for end-stage osteoarthritis of the knee. While many patients have positive functional and pain outcomes following primary TKA, a subset of patients have suboptimal outcomes, such as unexplained pain or aseptic loosening of the implant components necessitating revision of the index procedure. The understanding of the exact etiology of these suboptimal outcomes of primary TKA is in its infancy. In order to elucidate the etiology of failure in primary TKAs, a baseline for the factors contributing to arthroplasty failure and dissatisfaction must first be established. The purpose of this study …
