CCL (often mislabeled ACL) injuries in the German Shepherd Dog
by Keith Grossman on 12 July 2012 - 23:48
|I've been researching this subject as of late and am interested in hearing about the experiences of those who have experienced CCL injuries in their GSD's, how they were addressed, how they felt about the eventual outcome (i.e., was the dog ever able to resume normal activity, etc.) and what they would or would not have done differently. There are many schools of thought on this issue to include doing nothing (at least initially), bone modification surgery (TPLO, TTA), extrascapular and interscapular techniques including variants of those (TightRope, etc.) and would like to hear from those who have experience with any of these. I am also interested in hearin people's stories about recovery times, how they managed their dogs during recovery or anything else that you may feel pertinent to the subject that I might not have mentioned.|
Our breed is one of several that seems more prone to this injury than others and it's interesting to me to understand why people might think their particular dogs might have suffered it and opinions on how best to avoid and/or manage it if it should occur.

I found this interesting regarding early spaying/neutering:
A study by Salmeri et al in 1991 found that bitches spayed at 7 weeks grew significantly taller than those spayed at 7 months, who were taller than those not spayed (or presumably spayed after the growth plates had closed).(1) A study of 1444 Golden Retrievers performed in 1998 and 1999 also found bitches and dogs spayed and neutered at less than a year of age were significantly taller than those spayed or neutered at more than a year of age.(2) The sex hormones, by communicating with a number of other growth-related hormones, promote the closure of the growth plates at puberty (3), so the bones of dogs or bitches neutered or spayed before puberty continue to grow. Dogs that have been spayed or neutered well before puberty can frequently be identified by their longer limbs, lighter bone structure, narrow chests and narrow skulls. This abnormal growth frequently results in significant alterations in body proportions and particularly the lengths (and therefore weights) of certain bones relative to others. For example, if the femur has achieved its genetically determined normal length at 8 months when a dog gets spayed or neutered, but the tibia, which normally stops growing at 12 to 14 months of age continues to grow, then an abnormal angle may develop at the stifle. In addition, with the extra growth, the lower leg below the stifle likely becomes heavier (because it is longer), and may cause increased stresses on the cranial cruciate ligament. In addition, sex hormones are critical for achieving peak bone density.(4) These structural and physiological alterations may be the reason why at least one recent study showed that spayed and neutered dogs had a higher incidence of CCL rupture.(5) Another recent study showed that dogs spayed or neutered before 5 1/2 months had a significantly higher incidence of hip dysplasia than those spayed or neutered after 5 1/2 months of age, although it should be noted that in this study there were no standard criteria for the diagnosis of hip dysplasia.(6) Nonetheless, breeders of purebred dogs should be cognizant of these studies and should consider whether or not pups they bred were spayed or neutered when considering breeding decisions.

|Seriously? No one here has any experience with this?|

|Like your dog is neutered? Come on, who are you fishing for? LOL|

I've got no experience with it from any of my dogs.

|I had one diagnosed by 2 different vets, one specialist, one not. BOTH WRONG!!! Thankfully, "mothers' intuition" kicked in and I got a 3rd opinion. Poor dog almost had a TPLO for nothing but pano.|

|Or is it just keep on hammering until you get the one you want? I'm sure that happens, too!|

|Huge problem with Labs now....haven't heard it much in the GSDs.|

While some data seems to indicate the dogs that are neutered very young are more susceptible to CCL injuries, both neutered and unneutered animals suffer from the condition. What I am looking for is meaningful dialogue on a subject that is of some importance to the breed.

I think a lot of dogs may be misdiagnosed, Jenn, as there is no way of knowing for certain without either opening the dog up or using exploratory arthroscopy. Bone remodeling like TPLO should always be the last resort, IMO, not the first response but it is very lucrative for the surgeons recommending it.

|That's why I love my surgeon. The others diagnosed "drawer movement" and took xrays of the knees, but he didn't see the drawer movement as being abnormal for Caleb's age and size- his sense was immaturity, not injury. He used the SAME xray the others had taken and used and said "congratulations...he is still growing." I was skeptical that it was just pano, so he pulled some fluid off his knee to show me it was absolutely healthy. He said he just must have an extremely high pain tolerance to have had pano like that for so long and not shown any signs until injuring the leg running through the woods.|
Or maybe, as Bee suggests, I just hammer and hammer until I hear what I want. You know, because I don't really just care about my dog and want to get to the real crux of the problem when something doesn't make sense.
What's going on Keith?

|I'm sorry Jenni, you don't bother me today nearly as much as yesterday, I do apologize. Carry on as you will.|
