Abstract
The aim is to present a single-center case series of patients with symptomatic hyperpronated
feet treated with arthroereisis by using a second generation extra-osseous talo-tarsal
stabilization device. This case series enrolled 123 feet in 87 patients (20 [6-75]
years) treated with arthroereisis, either isolated (76 cases) or combined procedure
(47 cases). At their final follow-up, a patient reported questionnaire (overall satisfaction,
foot stability and shape, activities of daily living, pain level, and analgesics usage)
was distributed. The average postoperative follow-up period was 30 (13-55) months.
Nineteen (15%) cases required at least one revision surgery: the implant was manipulated
in 5 (4%), while 14 cases (11%) required definitive implant removal. The predominant
reason for implant removal was pain (50%), followed by implant migration (27%). The
pediatric population with isolated procedure showed lowest revision rate (5%), while
adults with combined ankle/hindfoot procedures demonstrated revision rate of 50%.
The overall patient satisfaction after arthroereisis was 84%. The patients’ perceived
improvement in foot stability was 75%, foot shape 85%, and activities of daily living
64%. Eighty-two percent of cases reported no analgesics usage in the last month and
mean visual analogue scale (0-10) pain level decreased from 5.5 to 2.2 (p < .001). The subgroup analyses of patient-reported questionnaires revealed the best
outcome in the pediatric-isolated cases, while adults with combined procedures reported
the lowermost outcome. Extra-osseous talo-tarsal stabilization demonstrated a low
rate of revisions surgery and a high satisfaction rate as an isolated procedure. Patients
with conjoined procedures experienced more revisions and considerably lower satisfaction
rates.
