ABSTRACT
Knee flexor muscle contracture
is frequent in patients with spastic cerebral palsy.
The purpose of the study was to determine whether
percutaneous tenotomy and aponeurotomy may
decrease knee flexor contracture in children with
spastic cerebral palsy.
Material and methods: A
prospective study of consecutive cases was conducted
from January to December 2009 in 24 children
with a diagnosis of moderate to severe spastic
cerebral palsy who had knee flexor contracture
with a popliteal angle ≥ 45° and a gross motor
function classification scale of 4 or 5; they underwent
percutaneous tenotomy and aponeurotomy
surgery and were followed-up for 24 months. Variance
analysis with a factorial design was used for
data analysis.
Results: The mean popliteal angle
was 83.48° preoperatively and 27.30° by the end
of the follow-up, with an improvement of 56.18°
(p < 0.01). Statistically significant differences were
found in all measurements comparing them with
the baseline values.
Discussion: Percutaneous aponeurotomy
of knee flexor muscles is described.
Compared to other procedures it provides the
benefits of minimally invasive surgery, mild postoperative
pain, short hospital stay –without using
immobilization during the entire process- and
children returned to their therapy program within
fi ve days.
Conclusion: Percutaneous tenotomy and
aponeurotomy of knee flexors was shown to be a
good alternative for the treatment of knee flexor
contracture in patients with spastic cerebral palsy.
