Summary

The goal of this prospective, cross-sectional study is to test the strength of the soleus muscle in participants who have a ACL tear confirmed by MRI. Previous studies have shown that the soleus muscle, which one of the muscles situated in the calf, decreases mechanical loading on the ACL. Therefore, we aim to test soleus muscle strength using a seated plantar flexor test.

The main questions we aim to answer are:

* Do patients with ACL tears demonstrate inter-limb soleus strength asymmetry (\>10%)
* Do patients with ACL tears have soleus muscle weakness compared with uninjured (normative) participants?
* Do changes in soleus strength values correlate with patient reported outcomes and stability, as measured by the IKDC questionnaire?

To achieve this the VALD force frame will be used as the testing device for plantar flexor strength testing. This device records the force generated by the movement. This will be repeated three times on each leg as part of the testing procedure. Furthermore, as part of the testing procedure participants will be required to fill out an IKDC form to assess their knee stability. Interrater reliability of the force frame will be investigated.

Further data from participants without ACL tears will be used to compare results. Thus allowing us to see if people with ACL tears have a weakness in the soleus muscle.
