Here, we present a protocol to measure the gap contact force and gap balance in mobile-bearing unicompartmental knee arthroplasty (UKA). Along with the clinical and radiographic data, we hope to determine the normal range of the contact force and set up the threshold of the gap balance.

The present protocol describes a modified parasternal long-axis view for swift and precise localization of the left anterior descending artery. This approach is designed to be simpler and more user-friendly while facilitating the examination of dynamic changes in coronary flow reserve following myocardial ischemia-reperfusion in mice.
