Meniscus tear observed incidence rates (% of observed tears within each study) from the literature. (A) Rates for affected meniscus (medial, lateral, or both) in adult (including adults with ACL reconstruction (+ACLR) and Athletes) and pediatric populations. Data from Jackson et al. (2019), Robinson et al. (2011), El Mansori et al. (2018), Kim et al. (2019), Ridley et al. (2017), Christino et al. (2019), Baker et al. (1985), Terzidis et al. (2006).^35–42 (B) Rates by region (anterior, body, posterior, multiple) in adult (including +ACLR and Athlete) and pediatric populations. Data from Jackson et al. (2019), El Mansori et al. (2018), Kim et al. (2019), Terzidis et al. (2006).^35,38–40 (C) Rates by vascular zone (outer = red-red, intermediate = red-white, inner = white-white, multiple) in the medial and lateral menisci in adult populations. Data from Terzidis et al. (2006).⁴⁰ (D) Rates by tear type and affected meniscus (T, M, and L) in general adults, ACLR+ adults, and adults who are athletes. Data from Jiang et al. (2017), El Mansori et al. (2018), Terzidis et al. (2006).^38,40,43 ACL, anterior cruciate ligament; L, lateral; M, medial; T, total incidence
