A cohort of 52 Native Canadians (NC) and 52 non-Native Canadians (NNC) were evaluated for knee laxity.

Objective laxity was measured using the KT-1000 tensiometer. Subjective findings were also recorded.
Comparison for instability between the groups (NC and NNC) revealed that the NC group had significantly greater laxity on both right and left sides for all knee ligament grading (p
