This graph says it all, HD.

Over the 20-year analysis period, significant annual growth was observed for the incidence of ACL injuries and knee contusions for both males and females (Figure 3) . For ACL injuries, annual growth rates were not significantly different between males (5.2% per year, 95%CI = 4.5–6.0%) and females (6.2% per year, 95%CI = 5.3–7.1%), whilst knee contusions displayed a significant interaction (p = 0.008) suggesting higher annual growth rates in females (4.9% per year, 95%CI = 4.4–5.4%) compared to males (3.8% per year, 95%CI = 3.

Also there seems to be a relatively high annual growth rate for ACL injury incidence in Australia of 10.4% and 7.3% per year, for 5–14 years-old females and males, respectively.
