Conclusion
Separation of syndromes associated with
congenitaldislocationandsyndromesassociated
with patellar aplasia or hypoplasia is artificial
and used here only for a didactic point of view.
When dealing with these pathology, careful
attention must be paid during clinical exam in
order to detect associated syndromes that could
impact the management of the patient.
Permanent dislocation in younger age can be
related with
many associated syndromes
;
whereas episodic dislocation is often isolated
but should consider connective tissues patholo
gies when generalized hypermobility is noticed.
The figure 6 summarizes where to look at when
a clinician deal with patellar dislocation, aplasia
or hypoplasia.
In case of familial history or small patella, a
genetic disorder is suspected: parent’s assess
ment, pelvis X-ray will be of major diagnosis
value (NPS, SPS and GPS).
And so the orthopedist surgeon will sometime
have to refer the patient to other specialist such
as geneticist, ophthalmologist, cardiologist, or
nephrologist…
