Knee motion after anterior cruciate ligament reconstruction (ACLR) has been shown to improve healing and bone integration of the tendon graft. However, no non-invasive quantitative methods exist with which to assess graft strain in the common clinical setting of ACLR. This study evaluates the use of ultrashort echo time MRI to objectively evaluate quantitative differences of ACLR tendon grafts in a rabbit model that have undergone different degrees of applied load.
