Tibial tuberosity advancement (TTA) versus a Tibial Plateau Leveling Osteotomy (TPLO) in dogs

As a follow on to yesterday's introductory post on a tibial tuberosity advancement (TTA), here is more from Dr. K on the subject.


Studies evaluating long term outcome of this procedure are currently being performed; however, the current short term follow up seems very promising. The procedure is currently being performed by over 200 veterinarians worldwide and seems to be quickly finding its place in the arsenal of treatment options for damage to the cranial cruciate ligament in canine patients.

I asked Dr. K how the TTA compares to the TPLO procedure and here is a summary of what she told me:

  • The TTA is less invasive but does not address dogs with very steep tibial plateau angles or very large/very small dogs)
  • The TTA is the newest surgical procedure for management of cranial cruciate deficiency in the dog. TPLO is more common than TTA but TTA was only released into clinical practice in 2005 while TPLO has been around since the 1990's.
  • Cost is variable by clinic but comparable between TTA and TPLO.
  • The biggest difference between the two procedures is that TTA moves the tibial tuberosity cranially to help use the quadriceps to neutralize cranial tibial thrust. TPLO undercuts the joint surface and rotates it so that thrust is neutralized. Because of the cut and the dissection, the TPLO is more invasive that the TTA, so patients that have a TTA tend to be more comfortable more quickly.
  • It is too early to tell the long term outcome from the TTA but so far it looks promising.

Has your dog experienced either of these procedures? Feel free to share in the comments so that others can share in your experience.

An introduction to a tibial tuberosity advancement (say that in one breath, can you?)

Confused about the difference between a TTA and a TPLO for your dog's torn cruciate ligament? I know, me too :) So, a vet friend-of-a-friend called Dr. K, agreed to write me up a ghost blog post on TTAs and what they are all about.

[Dr. K is shy and won't let me share her name or location but she-who-shall-not-be-named is a peach for doing this for me - you know who you are :)] 


Tibial tuberosity advancement or TTA for short is the newest procedure in the field of surgical management for rupture of the canine cranial cruciate ligament.

Cranial_thrust This ligament serves several functions in the canine knee (or stifle). It prevents overextension, excessive internal rotation of the stifle but most importantly prevents cranial shear. Cranial shear or tibial thrust is an abnormal motion in which the tibia (shin bone) shifts forward and the femur (thigh bone) will shift back, as in the diagram to the right. This instability of the knee results in chronic pain, inflammation and the development of arthritis.

Finding all the cool pet blogs over at Alltop

Alltop, all the cool kids (and me) In between business and family, I try to keep up with what the cool kids are up to in cyberspace (or the interweb as some of my favorite mommy blogs tell it - that always cracks me up!).

Goodness knows, there's about 5 mins between mouthfuls of lunch where I can fit my roaming in, but about a month ago, I discovered one of the newest and useful websites Alltop. Alltop is a service I'd wished I'd had 5 years ago when I was asking everyone where all the good pet blogs were but no-one knew. Darn it, I just had to find them all by myself. Bah humbug!

Geeking out - who owns certain pet insurance website domains?

I was playing around with Whois - a fun service for geeks who want to know who has registered a particular domain name. I figured I would take a look at who owns some hypothetical pet insurance domains - and what fun it turned out to be.

Let's start with www.purinapetinsurance.com - an obvious (but wrong) candidate for Purina to launch with. Who owns it? Strangely enough Veterinary Pet Insurance (VPI - largest pet insurer in the US) [if you are wondering, the Purina product is going out under www.PurinaCare.com.] Perhaps they have this because they used to have a relationship with Purina many years ago.
