Extracapsular "Tightrope" suture stabilization of torn CCL

I am looking for real world information from any who have experience with "tightrope" product from Arthrex which replaces the standard nylon fishing line used in extracapsular stabilization techniques that are not recommended for heavier dogs. (Arthrex claims tightrope is good for 250lb dogs)

There is very conflicting information out there about this procedure.
I am finding through persistent questioning that those opposed to it are actually talking about nylon suture used for many years which in fact is recommended for dogs under 25lbs.

When talking about the long term possibilities of a TPLO it is very scary to know it is a one shot deal and corrosion possibilities are high which can result in amputation or even death. (confirmed by my vet this morning)

My vet is against tightrope extracapsular stabilization for my 85lb dog but when questioned further, and persistently, he explained he knew little of the product but the procedure is widely known to fail in large dogs.
This was unsettling when I can find numerous vets around the globe who promote this technique for heavy dogs with using tightrope.
Arthrex website states min 40lb dog to 250lb dog recommended for this procedure to not replace all but most TPLO invasive surgeries.
Add in PRP (platelet rich plasma) into the mix and seems to me this is a winner as it is reversible if new technology comes out or if infection occurs.

(Already there is Bridge enhanced ACL repair trials in humans in Boston which may not apply to an old ACL injury but shows there are advancements occurring in one of the most popular injuries known to dogs. )

If anyone has had this done to their dog using "tightrope" on a large dog..over 70lbs, please inform us how successful this was. This product has only been out for 6 years (conception date).
With no actual medical studies done on its inefficiency, I feel some vets may be excusing its benefits unnecessarily for a more proven yet more invasive technique.

no experience with the tightrope procedure, but I have had hundreds of patients get TPLOs and have not had ANY issues with corrosion (not even sure what you mean, as all parts are stainless steel or related metals that are non-corrosive). Very rarely a patient will develop an infection (thankfully not happened to any of my own patients) or tumor (also never happened to anyone I have referred for this surgery). Never had one break down, either. MY experiences with TPLOs has all been positive, though before these were commonly done, extra capsular techniques were often tried, and often failed. IN fact, nothing worked all that great until the TPLO came along.

PubMed corrosion TPLO

We will definately go with what the new surgeon recommends on Monday.
I am sure TPLO is going to be the suggestion but I may opt for knee brace until I find more information from folks regarding the tightrope. The idea of extracapsular procedure is fantastic and the simplicity unmatched. If what Arthrex claims is true, TPLO will not be the leading operation in the world for this injury. Bridge enhanced ACL repair is very promising by allowing the regrowth or regeneration of the ACL instead of rebuilding or eliminating the need of one. Most common complaint with extracapsular procedure is breakage of the suture but the tightrope is said to be many times stronger. Not sure how to read the clinical measurements they use but if the numbers work the same in other measurements, at least 6 times stronger.

Do you have any info that you could provide on Arthex and this tightrope technique as it applies to the canine patient. A quick Google search only brought me to their main website, and it appears they are a human medical company with no mention is uses for their medical devices in any other species.
