This comparison does not assign a generated winner or score.
- Rat Achilles tendon injury (2019, J Orthop Res)
- 5 mg/kg twice weekly × 4 weeks, subcutaneous
- 60% increase in collagen deposition, 58% increase in vascular density at day 14
- Acute injury model only, 6-week endpoint
- Strong preclinical evidence for acute tendon injuries; mechanism well-characterized
- Rat patellar tendon injury (2021, Front Cell Dev Biol)
- 10 mg/kg three times weekly × 2 weeks, peritendinous
- 40% higher type I collagen, 35% lower type III collagen, improved tensile strength
- Peritendinous injection not practical in humans for all tendon locations
- Demonstrates collagen quality improvement, not just quantity. Critical for functional recovery
- Horse superficial digital flexor tendon injury (2018, Equine Vet J)
- 20 mg systemic injection weekly × 4 weeks
- Reduced lesion size on ultrasound, faster return to training
- Observational case series, no control group
- Large animal model more translatable to humans; positive but uncontrolled
- Human clinical trial data
- None published
- N/A
- No Phase I/II/III trials exist
- Regulatory and funding barriers prevent human studies despite strong preclinical data
