Patients' joint perception after anterior cruciate ligament reconstruction as a reliable patient‐reported outcome measure

Abstract

AbstractPurposeThis study aims to evaluate and compare patients' joint perception (PJP) with other commonly employed patient‐reported outcome measures (PROMs) in a cohort of patients following anterior cruciate ligament reconstruction (ACLR).MethodsA retrospective study was conducted on 108 patients who underwent ACLR between 2017 and 2021, with complete data available for visual analogue scale (VAS) pain, PJP, Forgotten Joint Score (FJS), Tegner Activity Scale, Lysholm Knee Scoring Scale, 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) at a mean follow‐up of 3 years. Spearman's rank‐order correlation was used to determine the correlations between clinical scores. A receiver operating characteristic (ROC) curve analysis was used to assess the discriminatory power of the chosen PROMs in detecting natural joint perception. Natural joint perception was defined as patients responding ‘like a native or natural joint’ or PJP = 1. This study hypothesized that PJP would demonstrate significant correlations with established PROMs, indicating its reliability and validity as a tool for assessing outcomes following ACLR.ResultsPJP showed significant correlations with all the reported PROMs, suggesting its potential as a valid and reliable assessment tool for evaluating ACLR outcomes. The ROC curve analysis indicated a good area under the curve for identifying natural joint perception using various PROMs. According to the PJP, nearly 20% of patients reported natural joint perception.ConclusionThis study evaluates PJP as a reliable 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.Level of EvidenceLevel III.
