investigating the relationship between patellar subluxation and patellar cartilage damage in magnetic resonance imaging of patients

Background: patellar subluxations can lead to cartilage defects, and pathological lesions of the patellar cartilage in recurrent patellar dislocation are known as patellar chondromalacia. however, the cause of patellar cartilage lesions in recurrent patellar dislocation (rpd) is not well understood. this study aimed to investigate the association between patellar subluxation and patellar cartilage injury on magnetic resonance imaging (mri) in patients referred to imam khomeini hospital during the year 2021-2022.method: in this cross-sectional study, patients diagnosed with patellar subluxation on mri were included. patients with incomplete medical records and other diagnosed patellar disorders were excluded from the study.results: our study results showed no significant relationship between patellar cartilage injury and gender. there was also no significant association between history of surgery and history of trauma. however, significant differences were found between age, weight, and patellar cartilage injury. further studies with larger sample sizes are recommended to investigate the relationship between patellar subluxation and patellar cartilage injury on mri in patients.conclusion: the findings of this study can contribute to reducing complications and improving outcomes in patients with patellar subluxation. additionally, it can prevent unnecessary diagnostic and therapeutic costs and enhance the quality of life for these patients.
