HSS Presents Research at 2024 AAOS Annual Meeting

At this year’s American Academy of Orthopaedic Surgeons (AAOS) Annual Meeting, HSS physicians and scientists presented exciting new research related to clinical advancements for care and patient outcomes in orthopedics.

Research highlights include the evaluation of artificial intelligence (AI) chatbots to provide accurate answers to medical questions about spine surgery, and two retrospective studies analyzing outcomes in both knee and hip replacement surgeries performed with robotic assistance. 

HSS Research Evaluates Whether AI Chatbots Provide Reliable Medical Information

A study co-authored by Sheeraz Qureshi, MD, MBA, co-chief of HSS Spine and colleagues identified nine frequently asked questions about cervical spine surgery, which they considered to be of particular clinical relevance. Question topics ranged from the benefits and drawbacks of different surgical approaches to side effects and recovery after surgery. The questions were inputted one at a time into ChatGPT version 3.5. Two experts in cervical spine surgery who were not involved in designing the questions rated the chatbot’s responses on accuracy, appropriateness, and readability. On average, the responses received a score of 8.1/10, with a 3.9/5 for accuracy and a 2.2/3 for appropriateness. The main drawback the reviewers noted was that ChatGPT failed to provide comprehensive responses, often omitting important factors. AI chatbots are more accurate than expected when asked to answer medical questions about spine surgery, however patients still need to use extreme caution when turning to these tools for help with medical decision-making.

New HSS Studies Highlight the Benefits of Robotic-Assisted Joint Replacement Surgery

HSS investigators presented two retrospective studies analyzing outcomes in both knee and hip replacement surgeries performed with robotic assistance.

The first study co-authored by HSS hip and knee surgeon Seth A. Jerabek, MD, and colleagues found that the use of a surgical robot during total knee replacement surgery reduced the need for manipulation under anesthesia, an outpatient procedure that may be prescribed when physical therapy after surgery becomes too painful for the patient due to joint stiffness caused by scar tissue.

The second study led by HSS hip and knee surgeon Elizabeth B.  Gausden, MD, MPH and colleagues compared short-term outcomes (e.g., rates of dislocation, re-operation, revision, and patient-reported outcome measures) of the anterior versus the posterior approach in robotic-assisted total hip replacement surgery. The investigators found that hip replacement has excellent outcomes with each respective approach when performed by surgeons with extensive experience in that approach. Additionally, it is likely that the very low incidence of instability or dislocation overall can be attributed to the use of robotic technology for planning and execution.
