Foot & Ankle International - 2017 FAI Supplement - 53S

Methods: Using the published billings from the Province
of British Columbia, the rates per year of surgical repair of
achilles tendon and delayed repair were determined. The
population of British Columbia has increased over the years
from 3.9 million in 1997 to 4.7 million in 2016.
The rates of acute and chronic surgery were plotted prior to
2010, and since 2010. The rates were fitted against time
using a linear and binomial plot. The rates in the years before
and after 2010 were compared with ANOVA and the change
of rate in time compared with Pearson's correlation.
Results: The rate of acute repair increased from 271 repairs
in 1997 to over 400 repairs per year in 2009. The rate of
acute repair has since dropped to just over 300 repairs per
year. This is reflected in the enclosed binomial plot. There
was a significant increase until 2010 (p<0.001), and a significant decrease since 2010 p<0.05) .

An average of 374 repairs per year (95% CI 349 to 398)
were performed before 2010, decreasing to 328 since (95%
CI 294 to 360), p<0.05.
The rate of late repair has increased from 48 per year (CI 40 to
56) to 80 (CI 70 to 91) since 2010. The rate of late repair
increased both prior to (r2 prior to 2010 .5, p<0.01) and since
2010.
Conclusion: The landmark 2010 paper has resulted in a
reduction of acute repair. However the increase in late repair
is concerning and indicates that the muscle tendon weakness observed in the 2010 paper on strength testing at 1 year
review in the non surgical group may be causing an
increased rate of late repair. Further evaluation and development of both surgical and non surgical technique is
required if the need for late repair is going to be avoided
that likely reflects poor patient outcomes.
