Haptic-visual evaluation of the J-Sign revealed a significant correlation with patella height, tibial tubercle: trochlear groove distance, trochlear bump height and the total number of risk factors for lateral patellar instability

J-sign assessment is considered a helpful clinical parameter in the treatment of lateral patellar instability (LPI). However, it is unclear whether there is a correlation between the degree of the J-sign and anatomic risk factors. The aim of this study was to investigate whether there is a correlati...

Zusammenfassung:J-sign assessment is considered a helpful clinical parameter in the treatment of lateral patellar instability (LPI). However, it is unclear whether there is a correlation between the degree of the J-sign and anatomic risk factors. The aim of this study was to investigate whether there is a correlation between the degree of the J-sign assessed by haptic-visual assessment and anatomic risk factors of LPI.
