Resumen (ES)
Introduction. Heterotopic ossification following primary
total knee arthroplasty is a poorly studied complication.
It was our purpose to study its incidence in our hospital´s total
knee arthroplasties series, and its clinical repercusion.
Materials and method. We retrospectively reviewed 798 primary
total knee arthroplasties performed between 1.995 and
2.003, 176 heterotopic ossifications (22,05%) being found. We
tried to classify the ossifications according to five reported
radiographic classification systems, although it was hard to
do in an important number of cases. Results. Only seventeen
cases had some clinical repercusion, and barely two of them
with persistent functional problems needed surgical excision
after a one-year maduration, with a good clinical outcome
after it. No correlation was found between the different
groups in the different classifications and the clinical relevance.
Conclusion. In this series we found that heterotopic
ossifications after primary total knee arthroplasty are relatively
frequent, most of them without symptomatic repercussion.
The few cases that needed surgical excision had good
outcome.
