Summarization of findings from the literature where the UKS was used to apply weight-bearing flexion methods of knee simulation.[14, 71–74]

Reference Baseline Condition Test Condition Flexion Angle Outcome Change
Hosseini, et al. 2011 non-weight- bearing static flexion 1*bodyweight 15° +131.4 N ACL force
30° +106.7 N ACL force
45° +34.6 N ACL force
Muller, et al. 2009 non-weight- bearing passive flexion 100 N weight-bearing full range +16° ITR
+2° valgus rotation
< +3 mm medial, anterior, and proximal translation
Lo, et al. 2008 weight-bearing alone 100 N weight-bearing
 & 50 N ATF 15–55° +33 to 55 N ACL force
full range > +2 mm ATT
 & 5 N*m ITT 15–55° negligible ACL force
>20° > +9° ITR
full range > +2mm ATT
Wunschel, et al. 2010 ACL-intact specimens ACLD, 100 N weight-bearing 20–40° > +2 mm ATT
 & 50 N ATF 15–65° > +4 mm ATT
 & 5 N*m ITT 15–30° > +2 mm ATT
All conditions full range no ITR change
Wunschel, et al. 2011 ACL-intact specimens ACLD, 50 N weight-bearing full range +2.4 mm ATT
 & 50 N ATF +3.1 mm ATT
 & 5 N*m ITT no ITR change
