Abstract
Aim
To correlate the surgical and MRI findings in acute lateral patellar dislocation and to determine the accuracy of MRI in identifying location of MFPL injury.
Methods
it's a retrospective study. Patients with first time dislocation of patella were admitted after reviewing in fracture clinic and MRI was arranged. Surgical repair of MFPL was performed within 2 weeks of injury. Arthroscopy was performed at the same time to remove osteochondral fragments and to confirm the diagnosis by viewing the area of haemorrhage deep to medial retinaculum. MRI was reported by consultant radiologist with a special interest in musculoskeletal system. MRI and surgical finding were compared.
Results
There were forty two patients with a mean age of 18.9. MRI was assessed to ascertain the site of MFPL disruption to allow focused surgical approach. On correlating MRI and surgical findings, MRI was 90% sensitive and 82.2% accurate in detecting site of MFPL disruption.
Conclusion
This study assesses the accuracy of MRI to confirm the site of disruption of MFPL and associated findings, allowing a focussed surgical approach.
