  • ACL graft weak point?


    This is my first subscription (and question) to Biomch-L so I
    apologise in advance for any netiquette that I do not observe in this

    My question relates to the time that an ACL graft is weakest
    following surgical reconstruction. From discussions I've had with
    orthopaedic surgeons, and the literaure I've come across, there
    appears to be two main schools of thought on the issue. Firstly,
    some believe that the graft is at it's strongest immediately
    following surgery and that various rehabilitative exercises can be
    progressed to as the patient attains sufficient limb function (e.g.,
    range of motion, quadriceps tone etc). Others suggest that there
    exists a point at approximately six weeks post-surgery where
    the graft will either have 'taken' or 'not taken' and that prior to
    this point exercises that elicit a high anterior tibial force should
    be avoided. I realise that there are many other important variables
    that need to be taken into account when prescribing exercise
    post-surgery but to keep this specific I'm wondering if any one could
    give me an insight into the graft strength side of things, or direct
    me to some relevant literature.
