This comparison does not assign a generated winner or score.
- TB-500 Protocol
- Actin sequestration → fibroblast migration → organised collagen deposition
- 14–21 days for measurable tensile strength improvement in animal models
- Parallel fibre alignment 68% vs 42% control (polarised microscopy, rat MCL study)
- Preclinical animal models only; no human RCTs
- Most promising peptide for ligament-specific repair based on mechanism and structural outcomes. But human dosing remains empirical
- PRP (Platelet-Rich Plasma)
- Growth factor release (PDGF, TGF-β) → proliferation signal
- Variable; meta-analyses show 10–20% faster return to activity in some tendon injuries
- Mixed; some studies show improved organisation, others show no difference from controls
- Multiple human RCTs; moderate-quality evidence
- Better-studied than TB-500 but mechanism less targeted to hypoxic ligament environment
- Standard RICE + PT
- Inflammation control + mechanical loading → gradual remodelling
- 6–12 weeks for Grade II tears; 12+ weeks for Grade III
- Baseline; collagen alignment depends entirely on load progression timing
- Established standard of care
- Proven safe, effective for most injuries. But no active regenerative mechanism
- BPC-157
- Angiogenesis promotion + fibroblast growth factor upregulation
- Comparable to TB-500 in rodent models (14–28 days)
- Less data on collagen alignment; more focus on vascularisation
- Preclinical only; no human trials
- Overlapping benefits with TB-500; may be synergistic rather than competitive
- NSAIDs (Early Use)
- COX inhibition → reduced prostaglandin synthesis
- Can delay healing if used in first 72 hours; anti-inflammatory effect counterproductive during proliferative phase
- No structural benefit; may impair collagen deposition if overused
- Established but increasingly questioned for acute soft tissue injury
- Appropriate for pain control after day 3–5; counterproductive if started immediately post-injury
