This comparison does not assign a generated winner or score.
- Animal model (Michigan 2021)
- Controlled lab study, rodent rotator cuff repair
- 48 rats
- Collagen I deposition at 4 weeks
- 35% increase vs controls
- Strong mechanistic proof—direct applicability to humans unclear
- Observational cohort (Texas 2024)
- Retrospective chart review, partial tears
- 47 patients
- MRI tear size reduction at 12 weeks
- 81% showed improvement
- Promising but lacks placebo control—confounded by concurrent PT
- Case series (post-surgical)
- Post-op follow-up, full-thickness tears
- 18 patients
- Tendon integration at 6 months
- 92% integration vs 78% controls
- Small sample—results directionally positive but underpowered
- Anecdotal (online forums)
- Self-reported outcomes
- Variable
- Subjective pain/function
- Highly variable—50% report benefit, 30% no change, 20% adverse effects
- Patient expectation bias likely—cannot separate TB-500 effect from natural history
