Artificial intelligence (AI) is rapidly changing the landscape of musculoskeletal care. Currently, AI in orthopedics bridges the critical gap between technical innovation and bedside practice. While research in this field is booming, clinicians must understand how to integrate these digital tools effectively. This evolution focuses on three primary domains: perioperative risk prediction, standardized imaging analysis, and large language models (LLMs) for workflow support.
Machine learning models now predict perioperative risks with high accuracy. For instance, transfusion risk modeling helps surgeons prepare for complex cases more efficiently. Consequently, these tools enhance patient safety by identifying high-risk individuals before they enter the operating room. Moreover, deep learning algorithms are revolutionizing musculoskeletal imaging. These systems automate tasks such as fracture detection and Kellgren-Lawrence grading for osteoarthritis. Such automation significantly reduces the diagnostic workload for radiologists and surgeons alike.
Despite these technical advances, routine adoption in clinical settings remains limited. Several hurdles prevent the seamless use of AI in orthopedics across diverse hospital environments. First, algorithmic opacity often creates a "black box" effect, which hinders clinician trust. Second, models frequently experience performance degradation when applied to new patient cohorts. Therefore, researchers now argue for a shift from increasing model complexity toward rigorous evaluation. Furthermore, external validation on independent cohorts is essential to ensure reliability.
Additionally, probability calibration and uncertainty estimation are becoming vital components of trustworthy risk communication. Clinicians need to know not just what a model predicts, but also how confident the model is in that prediction. Similarly, integrating these tools into existing electronic medical record (EMR) workflows is crucial for long-term success. Without a smooth fit, even the most accurate models may fail to provide a net clinical benefit.
Looking ahead, the next frontier involves multimodal digital twin approaches. These virtual replicas integrate EMR data, imaging phenotypes, and real-time intraoperative data. As a result, they can simulate patient-specific trajectories to optimize surgical planning and postoperative recovery. In summary, the clinical impact of AI will depend on life-cycle governance and demonstrated reliability rather than just retrospective benchmark performance.
AI is currently used for automated fracture detection, osteoarthritis grading, perioperative risk prediction, and providing administrative support through large language models.
External validation ensures that an AI model remains accurate and reliable when used in different clinical environments or with diverse patient populations beyond the original training data.
Digital twins allow surgeons to create personalized virtual models of a patient’s anatomy, enabling them to simulate surgeries and predict outcomes before an actual procedure takes place.
