  • Evaluation of optimal ACL-reconstruction in-vitro

    Dear all,

    looking in the literature for the evaluation of ACL-rupture operations in human and animal surgery I am not sure which method is considered to be best suitable to predict an optimal outcome beside clinical prospective or retrospective evaluations.

    However for the development of a "perfect" operation method I would like to set up an in-vitro evaluation method which gives me the maximal information on the predictable clinical usefulness. In theory a graft which mimics best the native ACL should give the best results. In other words, finding the method which restores best the biomechanics of the intact knee should be the best, right?

    The following methods are used to evaluate ACL-operations in-vitro:

    1. Measurement of the isometric placement of the ACL-graft with an isometer on the distal aspect of the graft
    2. Measurement of cranio-caudal movement (cranial drawer) of the tibia after graft placement
    3. Estimation of the helical axis of the femoro-tibial joint after graft placement
    4. Measuring the joint contact pressure on the medial and lateral joint surfaces

    Most of the papers using one of these methods were focused on one single detail. In contrast to those, I would like using a method which focus more on the whole joint biomechanics instead of evaluation only one aspect isolated from the rest.

    Sincerely, yours,

    Peter Böttcher.
