Core Tip	The Kellgren-Lawrence grading system remains a cornerstone for the radiographic assessment of knee osteoarthritis. Although invaluable for diagnosis, treatment stratification, and research, it has significant limitations. Key limitations include its dependency on radiographic imaging, inability to assess soft tissues or the patellofemoral joint, and variable correlation with subjective symptoms. A multimodal, patient-centered assessment strategy is recommended for optimal knee osteoarthritis evaluation.
