This book chapter explores patient-reported outcome measures (PROMs) for patellofemoral (PF) joint conditions, crucial for assessing disability, pain, and dysfunction. These measures provide insights into patient perspectives, aiding clinical decision-making and treatment monitoring. Despite various validated scoring systems available, no consensus exists on the optimal method for the assessment and follow-up of PF disorders. The chapter outlines 12 scoring systems offering a detailed analysis of their reliability, validity, and responsiveness. While disease-specific PROMs may offer sensitivity to subtle changes, there are still challenges in their responsiveness. Utilizing multiple tools enhances the understanding of patient pathology and surgical outcomes, though a gold standard approach remains elusive. This comprehensive overview underscores the importance of PROMs in clinical and research settings for PF joint conditions.
