TTA Repair Complications

Biz, Owner: Larry B.

For both humans and animals alike, any surgical procedure carries a risk of complications. You dog should have a full evaluation done, complete with blood work and other baseline testing, prior to surgery to help minimize any risks. Pre-surgical testing can often diminish the risk of death from anesthesia and other preventable complications related to your canine’s health. Overall, complications with cruciate surgery occur in approximately 5 to 10% of patients. Complications can range from mild and easily resolved, to more severe complications requiring additional surgery, expense and disability. While uncommon, complications do arise during and after tibial tuberosity advancement (TTA) repair procedures, and you should have a discussion with your veterinarian regarding ways to minimize and avoid these risks.

Complications and risks associated with tibial tuberosity advancement surgery:

  • Swelling around incision site – happens in about half of all dogs
  • Dirrhea, nausea or loss of appetite during post operative recovery
  • Incisional dehiscence – spontaneous separation of the incision site
  • Severed long digital extensor tendon
  • Tibial crest failure – this most often requires re-operation as the stability of the implant is compromised
  • Patellar luxations – dislocation of the knee cap; this can range from moderate to severe
  • Implant rejection and/or infection
  • Meniscal pain and post-op tearing of the meniscus
