Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The aim of this study was to describe the postoperative "baseline" magnetic resonance imaging (MRI) appearance of the ipsilateral thigh musculature after total knee arthroplasty (TKA). The secondary aim was to describe baseline muscle enzyme levels under the same clinical scenario. Neither of these measures have been reported previously.
