25 Years of Rizzoli OTT Review 🎉 (JEO 2023, Zaffagnini et al.)
OTT 25 years.pdf1.6 MiB
- 👥 Clinical experience: Technique developed at Rizzoli >25 years ago, performed in >6,000 patients worldwide, with multiple prospective cohorts and randomized studies
- 📊 10-year survivorship (267 patients):
- Revision rate: 1.1% at 2 years, 1.9% at 5 years, 3.7% at 10 years
- KOOS outcomes comparable to MOON registry benchmarks
- 🕒 20–24 year follow-up (original 1990s cohort):
- 86% normal/nearly normal knees
- 86% still active in sports (mostly recreational)
- No excess lateral compartment osteoarthritis
- 🔬 Biomechanical strength:
- 🩸 Biological advantage:
- 🛠 Versatility & safety:
Superior control of rotatory instability and pivot shift compared to isolated single-bundle or non-anatomic double-bundle techniques
Preserves tibial hamstring insertion → sustained vascularity, improved tendon–bone healing, stronger graft integration (supported by cadaveric, animal, and MRI studies)
Ideal for revision cases, skeletally immature patients, high-risk adolescents, and combined procedures; low 90-day readmission rate (~2.3%)
