Objective: Establish normative values for knee valgus angle during drop jump and step landings. Design: Observational. Setting: University biomechanics laboratory. Participants: 100 physically active asymptomatic individuals (50 male, 50 female) aged 18–28 years old. Main outcome measures: Knee valgus angle during drop jump and step landings. Results: There were no differences between genders during the step landing task (p < 0.12) but there were differences during the drop jump landing task (p < 0.048). Both males and females showed no significant differences between sides for either of the tasks (p > 0.05) or between the valgus angle generated for either of the tasks (p > 0.05). Conclusion: It would appear in order to be regarded as an average ‘‘normal’’ performance during a drop jump landing task knee valgus angle should be symmetrical and in the range of 7–13° for females and 3–8° for males. For a unilateral step landing task knee valgus angle should be symmetrical and in the range of 5–12° for females and 1–9° for males.
