Abstract
Introduction: Several scores are commonly used to evaluate patients'
postoperative satisfaction after lateral ankle ligament repair, including:
AOFAS, FAAM, CAIT and CAIS. Comparing published studies in the
literature is difficult, as the same patient can have markedly different
results depending on which scoring system is used. The current study
aims to address this gap in the literature by developing a system to
compare these tests, to allow better analysis and comparison of
published studies.
Patients and methods: This is a retrospective cohort study of
47 patients following lateral ankle ligament repair using a modified
Broström-Gould technique. All patients were operated between 2005
and 2010 by a single surgeon and followed the same post operative
rehabilitation protocol. Six patients were excluded from the study
because of concomitant surgery. Patients were assessed by an
independent observer. We used the Pearson correlation coefficient
to analyse the concordance of the scores, as well as scatter plots to
assess the linear relationship between them.
Results: A linear distribution between the scores was found when the
results were analysed using scatter plots. We were thus able to use the
Pearson correlation coefficient to evaluate the relationship between
each of the different postoperative scores. The correlation was found to
be above 0.5 in all cases except for the comparison between the CAIT
and the FAAM for the activities of daily living (0.39). We were,
therefore, able to compare the results obtained and assess the relative
concordance of the scoring systems. The results showed that the more
specific the scale is, the worst the score is and inversely. So the CAIT
and the CAIS appeared to be more severe than the AOFAS and the
FAAM measuring the activities of daily living. The sports subscale of
the FAAM demonstrated intermediate results.
Conclusion: This study outlines a system to compare different
postoperative scores commonly used to evaluate outcome after ankle
stabilization surgery. The impact of this study is that it makes
comparison of published studies easier, even though they use a
variety of different clinical scores, thus facilitating better outcome
analysis of operative techniques.
