Hi all,

I'm faced with the possibility that Erwin (3.5 y.o. lab, ~78lbs, well
muscled, good weight), *may* have buggered his cruciate (probably a partial
tear). We're going back next week when we can sedate him and have a really
in depth examination.

All he's doing right now, is he'll stiffen up in that leg a bit after lying
down for a while (he loosens up after a couple minutes). Anyways, assuming
he has screwed his cruciate, I have essentially two surgical options open to
me (I'm sure there are more, but these are the big ones available)..

1. TPLO - Pros -- Best available, quick recovery time, he likely won't blow
the other one while waiting for this one to heal.
Cons -- More expensive.
2. Don't know the name, but it involves stabilizing the joint with a nylon
cord.

Pros: Cheaper (my regular vet can do this one).
Cons: He's on the edge of what he likes to do weight wise. Longer recovery
time. Have to keep him quieter, longer (he's a lab remember? )

Third option, is to do nothing. He's not really bothered by it, but then
again he's pretty stoic (it took a while to even figure out that something
was wrong...at first I thought the stiffness might be related to another
problem he'd been having), so I wouldn't want to have him in pain and not
know about it.

Any thoughts on things I might not have considered?

Dale,

When Buddy did a partial tear in his the vet wanted to wait and let it go
and "hopefully"  he wouldn't tear it completely.  Well that wasn't the case
and when he finally blew it out a year later it was much worse than if I'd
just told him no fix it now.  Plus I didn't realize how much it bothered him
until I saw the change in his personality once the surgery was done.

I would have it repaired now with the nylon method its cheaper plus it's not
as invasive.  I've had 2 dogs and both have had surgery by this method with
really good results.  Of course they are going to get some arthritis even
after the surgery but nothing like they would if you wait and see.

Like you said he's a lab the recovery time is going to be crucial no matter
what method you choose.  I took a very long time to work Barney backup to
full running after his surgery.  The vet told me 8 weeks I stretched it out
to 5 months before I would let him off leash.  He was a sprinter and I could
just see him doing just that before it was healed completely and damaging it
again.  I'm glad I took that long because it made a huge difference for him.
Now with Buddy we did the regular 8 weeks recovery.  He's not a very active
dog and I had no fear of him running across the yard full tilt and hurting
himself.  Although he's ran down the ramp a few time since and jumped off
and almost slammed into the side of the car..........LOL

Good Luck
Celeste

I'd factor in Erwin's activity level. My dog was very athletic when he
tore his and not doing surgery wasn't considered a good option. He had
option 2 and 7 years later at 11 years old and 75 lbs, the arthritis and
HD are slowing him down.

He did the 12 week rehab and while I thought it would seem like forever,
 the time passed quickly and we bonded even more, starting the
gardening game "Throw the weed - just throw the weed!" We still play it,
but I no longer throw the weed right into his mouth. :)

Grrr. I hate this stage of learning. The more I learn, the more I doubt what
I thought I knew.
Been skimming some research articles that are claiming that the supposed
benefits of the TPLO are not all they are billed at. No (significant)
decrease in risk of arthritis later, no better restored function, problems
with the recommended TPA (apparently 5 degrees is recommended, but 5 degrees
is doesn't seem to be optimal).
Its hard, because most of this flies in the face of all the anecdotal
evidence I had before starting my research, and I don't (yet) have the skill
set to critically evaluate what I'm reading.

you might check out the yahoo group orthodogs. lots more information
to read and be overwhelmed by!

i opted for a traditional suture repair mostly because of the cost. my
dog's a 45 pound pit bull. she's doing well, back to normal activity,
and i'm (so far!) happy with the decisions i made as far as surgery.

......Personally I'd also be looking at a literature review or a review of
cases over a certain number of years.  Still, it depends so much on the
health of the dog to begin with, how careful the owner is in following rest
instructions afterwards, how skillful the surgeon was, and maybe even if
certain supplements were given to the dog after surgery,  that it's still
all a crap shoot as far as anything definitive.  If one particular surgeon
has data on his/her cases, to me that would be more reliable than a bucket
full of papers.  At least you would feel more comfortable with the outcome
with one particular person.

I don't (yet) have the skill
> set to critically evaluate what I'm reading.

.......a very neglected portion of any student's education, IMHO.  If read
critically, opposing conclusions usually point to something different in
methodology, procedure, etc.  And in the case of surgeries, there may be
something different that the surgeon is doing that he/she is not aware of.

.....at any rate, hope you have a good outcome, whatever you decide.
Remember this moment when you're wearing that white coat.

If it's a recent injury, and an athletic dog, you are better to do surgery
sooner rather than later, or not at all.  That being said, while it seems
that TPLO is touted as the "gold standard" for cruciate repair, I don't
think I agree.  I'm sure it works just fine, but the dogs that we've
referred have done no better (and in some cases have done significantly
worse) than those who had the "old fashioned" extracapsular repair.  We have
at least one patient who had his first ruptured cruciate repaired via TPLO.
He did just fine, but then blew out his other cruciate.  My boss performed
that surgery, and he actually had a quicker recovery and the owner was much
happier.  And while they may be weight bearing sooner, it actually takes a
long time for the bone to heal.  I had one dog who didn't have any
radiographic signs of healing even 3 months after the procedure, and the
orthopedist said "that's not unusual".  My boss does all our cruciates.  He
used to just use nylon line and tie 2 strands with knots.  He has switched
to a securos bone anchor system -- instead of having so much foreign
material and big knots, you use a bone anchor and crimps for the suture
material.  It is much faster for him to do, and the results seem to be
significantly better than with the old system.  So my vote now would be for
finding a vet who does the "old fashioned" repair but uses the securos
system and have it done that way!

...............and that to me would be worth more than papers.  On hands
real life experience.

I'm not really sure *how* old the injury is. Unfortunately we didn't catch
it right away (I have a feeling he did it on a walk with my Dad, but I can't
be sure). It coincided with some other issues, so to start with we (both
myself, and one of the vets) wrote it off as being related. Still don't know
for sure that he *has* injured it, but I think he has. Looking over my own
notes, and posts and what not, I'd say he did it nearly a month ago (which
makes me feel awful for not realizing something was wrong sooner, but he
didn't complain, so I didn't see it). The only thing that might put off the
surgery I think would be the diagnosis for his front leg. He seems to be
tender in places on that one too, and we don't know why (hopefully we will
on Friday).

That being said, while it seems

While I've been reading, I've come across a number of different names for
different techniques used,  but I'm not sure I understand them all. Theres a
LSS (lateral suture stabilization), ICS (intra-capsular stabilization),
Lateral Fabellar Technique. Can you give me an idea of kind of the broad
stroke differences in what these techniques are? (I've got a pretty good
handle on TPLO).

That sounds (somewhat) like the method that they do at the clinic I
volunteer at (obviously there may be differences in where exactly the nylon
line goes). The concern they have about doing it with Erwin, is that the
weight of the line might not be strong enough. I think the rule of thumb
they mentioned was that the weight of the line needs to be about twice the
weight of the dog. (So he's need about 150lbs line, which they have no way
of getting).

Bear had torn his at least a month before it was diagnosed - the vet
thought it was something else and was treating with prednisone. (Bear is
very stoic.) I finally drove to Memphis for a second opinion and that
vet figured it out quickly (and probably painfully - Bear has never been
good with any male vet since.)

Basically I'm saying don't feel awful. You are doing the best you can.

Peace,

Kate

A month isn't that old.  After 6 months you've probably already got so much
arthritis that surgery won't help as much.

I couldn't even begin to tell you the subtle differences between the many
textbook methods to repair cruciates, because I have no idea what they are!
My boss call's his method "modified flo's" which I'd never heard of.  I call
his technique extracapsular suture/lateral fabella/suture or something like
that.  It's definitely not intracapsular.

While that's the rule of thumb, in reality 80-100 lb test nylon seems to
work okay even for larger dogs.  I know my boss did an 80 lb dog with 100 lb
nylon with his older technique, and he just did a 95 lb dog with 100 lb
nylon with the securos technique.  Both dogs have done fine.  I think they
used to think (at least I was taught years ago) that the line actually
served as a replacement for the ligament.  Now it seems that the school of
thought is that the line only has to stablize the knee long enough for good
healing, and after several months it probably isn't even necessary.

Had Erwin at the vet's today, and we took some X-Rays, and checked out his
knees.

Good news bad news. Good news first. The good news is his cruciate doesn't
seem to be too bad. Probably *some* damage, but surgery isn't really a good
option at the moment.

Now for the bad news. His front left elbow (the other thing that's been
periodically giving him trouble), has some pretty ugly looking (well ugly to
me anyways... it looked pretty painful on the x-ray) arthritic changes.

We gave him a shot of cartrophen, which we'll be repeating in (about) 10
days, we also gave him a shot of metacam (because we'd been playing with his
sore joints), and lots of hugs and kisses : P . We're also switching his
food over to mobility support (royal canin).
