    That may well be the case, but surely following a knee arthroplasty they are now more active --> walk more --> greater loading on foot!

    Quote (my emphasis).
    "Surgeons have questioned whether foot deformity applies abnormal loading on a knee implant. A total of 24 patients with mild knee deformity underwent a static recording of foot loading prior to and at 3 months following knee replacement. Of these patients, 13 had a preoperative varus deformity. The recorded postoperative to preoperative loading in all 6 geographic sites was decreased by an average of 10%. The largest changes were observed in the hallux and lesser toe masks, whereas the postoperative to preoperative foot pressure ratio in the metatarsal head (lateral and medial), heel, and midfoot masks was 0.94. This preliminary investigation reveals a minimal change in geographic foot loading following total knee arthroplasty in patients with mild knee deformity."

    Craig is right. I have witnessed exacerbated hip pain in patients with new knees, usually over one year post-op.
    Plus, in my book anyway, static foot loading in a small cohort tells us very little.

    I started to look into a correlation between foot position and total knee replacements (TKR) a while back. I didn't find much.
    I sat in on several TKR clinics, where weightbearing foot position was not even considered. Interestingly the tibial inter-medullary jig used for obtaining a straight knee during surgery stops at the level of the talocrural joint, although the design may have changed since I last looked.
    Anecdotally (from other post-grad students in my dept who were doing research on knee and hips, mostly to do with prosthesis wear) this particular Trust had a lot of revision surgery going on because of post-op patellar pain.

    I talked to another Orthopod from a different Trust a year or so ago about this. His view was that foot position made little or no difference to TKR outcomes, and that they did very little revision surgery:confused:.
     
  5. There is some pretty cool research now using instrumented total knee joint implants and tibial force transducers which can measure knee joint and tibial loads in vivo postoperatively.

    I am currently treating a patient with a rapidly progressing PTTD following a successful knee replacement. He could see the deformity getting worse every day.
