Vastus lateralis fibrosis in habitual patella dislocation: An MRI study in 28 patients

Iatrogenic retractile quadriceps fibrosis within children in Benin: Epidemiological, clinical, therapeutical aspects

“…Lowers limbs length inequalities and the associated hip diseases in our series were not previously reported. Although new methods of investigation in imaging such as ultrasound [5,6] and magnetic resonance imaging [9,16] provide more information on the local lesion transformations, the standard radiography, the only available method in our context, was sufficient to assess bone deformities. Outcome rate of conservative treatment by IMK in our series was (10.58%).…”

“…Medical records and surgical reports were used as data sources and this covered only children under 16. This survey was conducted in three hospitals in Benin.…”

Habitual patellar dislocation in children: Results of surgical treatment by modified four in one technique

“…11 Lai et al showed that vastus lateralis has fibrosis and muscle fibre degeneration on histopathology and MRI examination. 16 Joo et al described four in one procedure for habitual dislocation of patella in children. It consists of lateral release, proximal tube realignment of patella, semitendinosus tenodesis and transfer of patella tendon.…”

First-time patellar dislocation with resultant habitual dislocation two years later, which was not demonstrated on plain X-rays halfway: a case report

“…In contrast with recurrent dislocation, the factors contributing to the onset of habitual dislocation and its time course from initial dislocation have not been elucidated despite previous reports of an association with quadriceps fibrosis due to muscle injections [14-16], quadriceps contracture [17], and abnormal attachment of the iliotibial tract to the patella [18], none of which were applicable to our case. Among the various parameters evaluated in our case, modified Q angle, sulcus angle, and lateral deviation angle showed aberrations.…”
