Machine learning algorithm may identify patients at risk for extended opioid use
Dr. Joseph Schwab, Chief of the Orthopaedic Spine Service, conducted research to develop and test machine learning algorithms to predict extended post-op opioid use.

Here is a sample of the research our faculty will be presenting at AAOS 2021:

Foot & Ankle:

  • Management of Most Common Foot and Ankle Pathologies
  • Utility of Weightbearing Computed Tomography to Diagnose Syndesmotic Instability
  • Suture Tape Reinforcement Device as an Independent Fixation Solution


  • Failed Reverse Shoulder Arthroplasty
  • Managing Intraoperative and Early Postoperative Problems in Shoulder Arthroplasty
  • Management of Humeral and Glenoid Bone Deficiency in Shoulder Arthroplasty

Hand & Arm:

  • Assessment and Management of Distal Radius Fractures
  • Managing Challenges in Thumb Carpometacarpal Arthritis
  • Assessment and Management of Complex Fracture and Fracture Dislocation of the Proximal Forearm


  • New Perspectives in Musculoskeletal Infections
  • Is it the Back or the Hip? Differentiating Lumbar Spine from Hip Pathologies
  • Artificial Intelligence in Orthopaedics: Machine Learning, Natural Language Processing, and Deep Learning

Hip & Knee:

  • Same Day Discharges following Primary Total Joint Arthroplasty
  • Characterizing the Incidence of Avascular Necrosis after Corticosteroid Injections of the Hip
  • Outcomes of Tourniquetless Revision Total Knee Arthroplasty

Sports Medicine:

  • Application of Machine Learning Algorithms in the Prediction of Prolonged Postoperative Opioid Use
  • Telemedicine after COVID-19: Incorporating Virtual Visits into an Orthopaedic Practice
  • Hip Corticosteroid/Anesthetic Injections


  • Silver-Coated Megaprostheses in the Mitigation of Prosthetic Joint Infections
  • Wound Vac Temporizing
  • Sarcopenia and Muscle Attenuation by Computed Tomography Predict Mortality
