We have just had brought over from Leicester Royal Infirmary The Leicester
Knee Arthrometer which is similar to the KT1000 types measuring knee joint
laxity but only in the AP plane. I am hoping to use it to review some of
the 5 year ACLRs and for looking at the outcomes on our new fixation
techniques. However researching the literature on the subject although
arthrometry is more often than not used it does not often correlate to the
functional outcome that the patient gets. So I am also going to use more
functional outcome measures eg hop tests and hopefully (funding permitted)
try using the Biodex Stabilisation System which is like an electronic
wobble board to investigate more functional proprioception. If anyone has
had experience clinically or in research with this system I would be
grateful to hear from them as we are currently looking for some evidence of
it's use in knees, ankles etc to support bids for purchasing it.
Going back to the joint laxity question. I have not come across anything
that measures medial -lateral laxity but there is a device that can be used
to look at rotational instability but again this is in a non-functional
position.
If you want any refs for the arthrometry please contact me at leicester
General hospital (0116) 2490490 bleep 4148 I've got quite a few of them!
