Primary Outcome Measures

Name	Time	Method
The difference in Visual Analogue Scale (VAS) for pain after ten single leg decline squats between the patellar strap and control condition will be used as the main study outcome in this study. <br>

Secondary Outcome Measures

Name	Time	Method
The difference in VAS pain score between both conditions (control and strap) during the jump test and the triple hop test are secondary outcomes, as well as the height (m) and distance (m) measured during these tests. In addition, the difference in proprioception (Joint Position Sense expressed by the deviation in millimeters from a marker) between both conditions is also a secondary outcome measure. <br><br>The difference in percentage of echotypes 1,2,3 and 4 between the follow up UTC measurement (effect of a patellar strap) compared to the baseline UTC measurement (no patellar strap) are also secondary outcomes. Finally, the comfort grade (0-10) of wearing the Genupoint patellar strap is a secondary outcome parameter.
