Abstract
ABSTRACT
Habitual patella dislocation is a rare entity and its occurrence with osteogenesis
imperfecta (OI) has not yet been documented. Various surgical techniques have
been described in the literature for its treatment, but no single standard procedure
is shown to be effective. A 24-year-old girl, diagnosed with osteogenesis imperfecta,
presented with complaints of pain and instability in both knees, more on the right.
She was diagnosed to have right habitual patella dislocation. She had prominent
quadriceps muscle wasting and X-rays confirmed patella baja. CT scan and MRI
suggested trochlear dysplasia, Dejour type A and a normal Tibial tuberosity (TT)
- Trochlear groove (TG) distance. She was operated with lateral release, medial
plication and tibial tuberosity transfer. She had a full knee range of motion (ROM)
and pain-free ambulation in four months. In one year follow-up, she had good
functional outcome.
