ACL AND MPFL CONCURRENT RUPTURE RATE: AN MRI STUDY

2018 
SummaryNearly one-third of patients in this series with an ACL rupture requiring reconstruction had evidence of MPFL injury. This should be considered when patients are seen, and when MRI scans are reviewed/reported.IntroductionThe Medial Patello-Femoral Ligament (MPFL) is the largest component of the medial parapatellar ligamentous complex. The senior surgeon felt that there was an anecdotally high rate of MPFL injury amongst his patients undergoing Anterior Cruciate Ligament (ACL) repair, but no discussion of this in the present literature.MethodA literature search was performed; although there were both scanty radiographic and anatomical studies of the MPFL, we found no literature looking at ACL and MPFL concurrent injury rates. The Magnetic Resonance Imaging (MRI) scans of fifty consecutive ACL reconstruction patients were retrospectively reviewed. Two independent radiologists were asked to review the scans looking specifically for evidence of MPFL rupture or Injury. The degree of injury was rated as ...
