  • Help, opinion on ACL reconstruction surgery

    Dear BIOMCH-L'ers,

    I understand that the following message does not conform to the usual
    information request subscribers are used to, however, this request
    is very dear to me and I believe that the Biomch-L community could give
    me a unique point of view and useful feedback.

    I am an athletically active 35 year old male, that has
    just been informed that I have a total rupture of an ACL. Having much
    experience in virtual knee simulation for the purposes of total knee
    replacement design, I understand the instability pattern from a academic
    and now (ouch!) personal point of view.

    The usual orthopaedic surgical procedure is to transplant a piece of the
    patellar tendon, to reconstruct the ACL. My concern is, that the mechanical
    qualities (lateral stiffness variation, attachment geometry, fanning, etc.)
    of the ACL will not be matched exactly by both the patellar tendon
    itself and new interface. I am worried about the effects of this disparity
    on stability, maniscus stress, ligament/bone interface stresses, etc.

    My questions to the community is: Has anyone had this procedure done to them
    and what were/are the results (are you happy you had it done?), Does anyone
    know the durability of the new mechanism (will I need maintenance?), What is
    your biomechanical opinion of this procedure.

    Thank you for you attention.
