Table 2 Results of the studies and factors excluded from the meta-analysis
Study | Reason for exclusion of meta-analysis | Results |
|---|---|---|
Smeets et al. 2019 [42] | Only study assessing knee abduction as a mean across the entire landing phase (kinematics) and not reporting sufficient statistics (kinetics) | No difference in 3D knee abduction angle or peak knee abduction moment during a double-leg vertical drop jump between those who sustained an ACL injury (n = 4) and controls (n = 35), p > 0.05) |
Numata et al. 2017 [40] | Only study that reported peak MKD and MKD at initial contact | Those who sustained an ACL injury (n = 27) had greater baseline MKD at IC (mean (sd), 2.1 (2.4) vs 0.4 (2.2) (p = 0.006) and greater peak MKD, 8.3 (4.3) vs 5.1 (4.1) (p = 0.007) compared to controls (n = 27) during a single-leg drop landing |
