Purpose: To evaluate and compare the Patients' Joint Perception (PJP) with other commonly employed patient-reported outcome measures (PROMs) in a cohort of patients following anterior cruciate ligament reconstruction (ACLR). Methodology: A retrospective study of 108 patients who underwent ACLR between 2017 and 2021, with complete data for visual analogous scale (VAS) pain, PJP, forgotten joint score (FJS), Tegner, Lysholm, Anterior Cruciate Ligament Return to Sport After Injury (ACL-RSI), Single Assessment Numeric Evaluation (SANE), Cincinnati Knee Rating System (CKRS), and The Hospital for Special Surgery Anterior Cruciate Ligament Satisfaction Survey (HSS-ACL-SS) scores at a mean follow-up of 3 years. Spearman's rank-order correlation was employed to determine the correlations between clinical scores, and Receiver Operating Characteristic (ROC) curve analysis was conducted to assess the discriminatory power of the chosen PROMs for detection natural joint perception. Results: PJP demonstrated significant correlations with all the reported PROMs, suggesting its potential as a valid and reliable assessment tool for evaluating ACLR outcomes. ROC curve analysis showed a good area under the curve (AUC) for identifying natural joint perception using various PROMs. We found a nearly 20% ceiling effect for PJP, which is deemed satisfactory. Conclusion: This study evaluates the PJP as a reliable and useful tool for assessing patient outcomes following ACLR. Its significant correlation with other established PROMs underscores its potential as a valuable addition to the existing array of PROMs in ACLR.
