ChatGPT, an AI-powered chatbot, utilizes natural language generation to provide human-like responses across various topics, including medicine. It continuously learns and improves through advanced algorithms. ChatGPT offers up-to-date information on diseases, symptoms, and treatments in healthcare. Its latest iterations, GPT-3.5 and GPT-4.0, enhance accuracy and performance. This study evaluates ChatGPT’s patient education capabilities by comparing GPT-3.5 and GPT-4.0 in explaining fifteen foot and ankle orthopedic conditions. Additionally, Foot and Ankle Orthopedic Surgeons assess the accuracy of the provided information.

Fifteen foot and ankle orthopedic conditions were presented to ChatGPT (GPT-3.5 and GPT-4.0) using the standardized prompt: “I have been diagnosed with [condition]. Can you tell me more about it?” The generated responses were compared to publicly available information from the American Orthopaedic Foot & Ankle Society (AOFAS) Foot Care MD patient information sheets within the same time frame. Each inquiry was conducted in a separate chat session to prevent ChatGPT from referencing prior responses. To evaluate the accuracy of ChatGPT’s information, two fellowship-trained foot and ankle orthopedic surgeons (A.B. and G.I.P.) independently reviewed the outputs. They categorized their accuracy into four tiers:
