Objective: A brief review of the literature to provide an overview of knee valgus angles during different hop tasks.
Methods: A literature search was conducted; electronic databases used included PubMed, and SCOPUS. The inclusion criteria were English language, and publication between January 2010 and May 2015, which assessed the knee valgus angles during hop landings. The studies were evaluated by the researcher through their titles, abstract, as well as how the investigation functioned according to the inclusion/exclusion criteria of the present study.
Results: A total of 2 papers were included with full-text, as various studies incorporated designs for knee valgus testing which resulted in alternate findings that could not be analysed or evaluated.
Conclusion: No extensive research has been carried out over the past 5 years to evaluate knee valgus angles during hop tests. However, the current study found that the majority of the published studies during 2010 – May 2015 focused on evaluating the performance of landing tasks among participants in different sports (basketball, volleyball). Moreover, it can be concluded from the present review that there still exists failings in the evaluative results from past studies regarding the definitive comparisons between knee valgus angles upon landing, which occur through the measurement of important variables in the utilisation of 2D video analysis (i.e. when using crossover hop tests to measure knee valgus angles).
