To determine whether the findings from a landmark Canadian trial
assessing the optimal management of acute rupture of the Achilles
tendon influenced the practice patterns of orthopaedic surgeons
in Ontario, Canada. Health administrative databases were used to identify Ontario
residents ≥ 18 years of age with an Achilles tendon rupture from
April 2002 to March 2014. The rate of surgical repair (per 100 cases)
was calculated for each calendar quarter. A time-series analysis
was used to determine whether changes in the rate were chronologically
related to the dissemination of results from a landmark trial published
in February 2009. Non-linear spline regression was then used independently
to identify critical time-points of change in the surgical repair
rate to confirm the findings.Aims
Materials and Methods
The aims of this study were to establish the incidence of acute
Achilles tendon rupture (AATR) in a North American population, to
select demographic subgroups and to examine trends in the management
of this injury in the province of Ontario, Canada. Patients ≥ 18 years of age who presented with an AATR to an emergency
department in Ontario, Canada between 1 January 2003 and 31 December
2013 were identified using administrative databases. The overall
and annual incidence density rate (IDR) of AATR were calculated
for all demographic subgroups. The annual rate of surgical repair
was also calculated and compared between demographic subgroups.Aims
