Abstract

The J-sign patella is an erroneous movement or tracking of the patella during knee movement, particularly when moving laterally during knee flexion, which can be symptomatic of patellar malalignment or instability, essential in developing and progressing knee osteoarthritis (KOA). The study aimed to determine the clinical significance of the J-sign patella as a diagnostic and prognostic tool in patients with KOA. The objective of this study was to comprehensively evaluate the clinical and pathophysiological importance of the J-sign patella in the onset, progression, and management of KOA, with a particular emphasis on its diagnostic, prognostic, and therapeutic implications. A systematic search was conducted to discover all relevant studies on the J-sign patella and its relation to the OA knee. Databases such as PubMed, Cochrane Library, and Scopus were used. A few research studies show the clinical significance of addressing J-sign patella in treating KOA.
