Studies & References 

Now with 59 different cage sizes, TTA RAPID® is the most flexible surgical technique designed to repair a cruciate ligament injury. It allows for shorter surgery times, which means lower risk of infection and less costs.


Veterinary Journals and Publications

After more than 150,000 successful surgeries worldwide, TTA RAPID® has been shown to reduce surgery time, reduce infection rates, and get patients back on their paws quickly. Here are some references and scientific journals about TTA RAPID® Implants and the TTA RAPID® Technique:

Evaluation and application of the TTA-RAPID method in the treatment of cranial cruciate ligament rupture in dogs (Acta Veterinaria, June 2017)

This study evaluated the clinical outcomes of TTA Rapid surgery in 17 dogs with CCL ruptures. Fourteen (82.4%) dogs had a good to excellent outcome 3 months after surgery. It has been concluded that the TTA RAPID® technique procedure is a fast, easy to learn and non-invasive treatment of CrCL ruptures in dogs.

Tibial tuberosity advancement in small-breed dogs using TTA Rapid implants: complications and outcome: TTA RAPID® in small breed dogs (Journal of Small Animal Practice, March 2017)

In this study, 40 dogs with cranial cruciate ligament insufficiency and body weight of 15 kg or less were evaluated, with outcomes rated excellent by 88% of the clients and good by 7%. 94% showed good to excellent limb function only 6 weeks after surgery. 

TTA-RAPID in the treatment of the canine cruciate deficient stifle: short- and medium-term outcome: TTA-RAPID in the treatment of the canine cruciate deficient stifle (Journal of Small Animal Practice, January 2017)

This study shows good short- and medium-term outcomes and low complication rates of the 152 procedures carried out in 141 dogs using the TTA RAPID® Technique.

TTA RAPID: Description of the Technique and Short Term Clinical Trial Results of the First 50 Cases (Vet Surg., May 2015)

This study shows that the majority (96%) of dogs achieved a good to excellent outcome three months after surgery, indicating that the modified TTA RAPID® Technique is a viable and promising alternative for addressing CCL rupture in dogs.

Modified Tibial Tuberosity Advancement Rapid in a Dog with One Contralateral Amputated Limb (Vet Sci., September 2022)

TTA RAPID® Technique was performed to treat CCLD in a dog with a contralateral amputated hindlimb and showed that by the second day after surgery, the dog was able to stand on his own. After three months, the dog was free of lamenss and the osteotomy site was completely healed.

Comparison of Outcomes Associated with Tibial Plateau Levelling Osteotomy and a Modified Technique for Tibial Tuberosity Advancement for the Treatment of Cranial Cruciate Ligament Disease in Dogs: A Randomized Clinical Study (VCOT, July 2019)

This study shows high long-term success rates and faster recovery periods in dogs treated with TTA RAPID®.

Long-Term Clinical and Goniometric Follow-Up of TTA RAPID Surgery in Dogs with Cranial Cruciate Ligament Rupture (Acta Vet Eurasia, 2021)

This study involved ten dogs of various breeds, 54.9 ± 24.6 months of age, weighing 35.8 ± 5.6 kg, with unilateral CCL rupture. It has been found that all ten dogs had a good to excellent outcome 52 weeks after surgery, and that the use of TTA RAPID offers an alternative for treatment of CCL insufficiency in dogs, with complication rates comparable to previously reported ones and a high degree of owner satisfaction.

Experience with the TTA RAPID® Technique

Dr. Haroush says,

“In a large percentage of our cases, we find that the TTA RAPID® provides the best result with a lower complication rate and the fastest, least restrictive recovery. We find that patients walk better two-days post surgery that they did on initial presentation which makes our client, our patients - and obviously us - much happier.”
