Intérêt de l'IRM dans le diagnostic des luxations ou subluxations récentes de la rotule‎ : à propos de 39 cas

Abstract : The purpose of this study is to estimate the interest of MRI in the diagnosis of recent patellar luxation or subluxation. This work was based upon clinical, radiological, and MRI analysis of 39 cases. The middle age was 22.8 years old, there were 24 men and 15 women, time to MRI was 13.7 days. The study protocol was: after collection of clinical examination and radiological analysis in emergency, when diagnosis was proved or suspected, we had MRI to document the accident. We studied in MRI the elements which allowed the diagnosis (bone bruise: femoral condyle and patella, MPFL lesion, cartilaginous lesion) and the associated lesions. Among 35.8% of radio-clinical incertitude, MRI confirmed 92,8%of luxation. All things considered, we found 37 diagnosis confirmation with MRI. Among them, we indentified 84 % extern femoral condyle lesion and/or patellar lesion, and 67.5 % of MPFL lesion. MRI detected 11 cartilaginous lesions. Among them, 7 had a therapeutic interest (intra-articular fragment) and ended at surgery. MRI showed 13.5% associated lesions: one complete tear, 2 partial ACL injuries, and 2 MCL (medial collateral ligament) injuries, which needed therapeutic modifications. We confirmed other series results about difficulties to establish diagnosis; we had similar results about documentation MRI. Therefore, we have confirmed that MRI is the exam of reference of patellar luxation. In addition, it allows to detect associated lesions which are current in this type of traumatism and which are not diagnosed in emergency. That's why MRI ends at an optimal treatment of this patellar traumatism.
