The total and specific numbers of time-loss injuries, incidence proportions (IP) and matches missed, as well as related costs, are presented in Table 1. The number of total time-loss injuries rose from 129 in 2008 - 2009 (IP = 0.57) to 202 (IP = 0.55) in 2010 - 2011, decreasing to 162 (IP = 0.53) in 2012 - 2013 (repeated measures ANOVA not statistically significant). The number of total matches missed rose from 506 in 2008 - 2009 to 1110 in 2010 - 2011, decreasing to 542 in 2012 - 2013. This difference in matches missed over five seasons was found to be statistically significant (P < 0.01) through repeated measures ANOVA. Computed Bonferroni pairwise comparison between 2010 - 2011 (before ‘Minimum Medical Standards’) and 2012 - 2013 (after ‘Minimum Medical Standards’) in matches missed was statistically significant (P < 0.05). The number of knee time-loss injuries rose from 37 in 2008/2009 to 78 in 2010/2011, decreasing to 37 in 2012/213 following the introduction of ‘Minimum Medical Standards’.
