摘要

ObjectivesTo assess inter- and intra-rater reliability of classification of the J-sign as “large” versus “small or none” as compared to another two-level system (“present” versus “absent”) and a three-level system (“large,” “small,” or “none”) and to identify anatomical and patient factors associated with presence of a large J-sign.MethodsForty patients (40 knees) with recurrent patellar instability were prospectively enrolled and recorded on video actively extending their knee while seating. Four raters classified patellar tracking on two separate occasions using three systems: 1) Two groups: J-sign versus no J-sign, 2) Three groups: large J-sign, small J-sign, or no J-sign, and 3) Two groups: large J-sign versus small or no J-sign. Intra- and inter-rater reliability of each system was assessed using Kappa statistics. Anatomical (trochlear dysplasia, TT-TG distance, patellar height) and patient (Beighton score) factors as well as KOOS subscales were compared between patients with a large J-sign and patients with a small or no J-sign.ResultsInter- and intra-rater reliability was found to be highest with the two-level classification system of a large J-sign versus a small or no j-sign (Inter-rater Kappa = 0.76, Intra-rater Kappa = 0.75). Patients with a large J-sign had more severe trochlear dysplasia as assessed with the sulcus angle (p = 0.042) and were more likely to have a tight lateral retinaculum (p = 0.032) and elevated Beighton score (p = 0.009). No significant differences in KOOS subscales were noted based on presence of large J-sign versus small J-sign or no J-sign.ConclusionQualitative visual assessment of patellar tracking with the J-sign demonstrates substantial inter- and intra-rater reliability, particularly utilizing a two-group classification system to identify knees with a large J-sign. Patients with a large J-sign demonstrate an increased incidence of a tight lateral retinaculum, generalized ligamentous laxity, and trochlear dysplasia.Level of EvidenceLevel III - Cross-Sectional Study.
