🦶 Plantar Fascia Microtear & Degeneration Simulator

Healthy Plantar Fascia Under Normal Load

Placeholder: the fascia band tensions and releases normally with gait.

• Parallel: Fiber alignment (Placeholder short note)
• High: Tensile capacity (Placeholder short note)
• Minimal: Microdamage rate (Placeholder short note)
• Positive: Repair balance (Placeholder short note)

Normal fascia biomechanics

Placeholder: healthy collagen bundles distribute load evenly across the arch.

Repetitive Overload Exceeds Repair Capacity

Placeholder: repeated cycles outpace the tissue's ability to recover.

• Rising: Load cycles (Placeholder short note)
• Shortened: Recovery window (Placeholder short note)
• Elevated: Strain peaks (Placeholder short note)
• Cumulative: Fiber stress (Placeholder short note)

Overload accumulation

Placeholder: cumulative strain begins to outstrip normal repair processes.

Collagen Fiber Microtears Appear

Placeholder: small ruptures form within the collagen fiber bundles.

• Increasing: Microtear count (Placeholder short note)
• Interrupted: Fiber continuity (Placeholder short note)
• Mild: Local inflammation (Placeholder short note)
• Possible: Pain onset (Placeholder short note)

Fiber-level microdamage

Placeholder: microtears scatter along the fascia, weakening load transfer.

Degeneration at the Calcaneal Insertion

Placeholder: damage concentrates where the fascia meets the heel bone.

• Declining: Insertion integrity (Placeholder short note)
• Concentrated: Microtear density (Placeholder short note)
• Common: Heel pain (Placeholder short note)
• Elevated: Bone spur risk (Placeholder short note)

Insertion site failure

Placeholder: the calcaneal attachment becomes the focal point of damage.

Chronic Fasciosis — Degenerative Tissue Change

Placeholder: disorganized scar-like tissue replaces healthy collagen.

• Disorganized: Tissue organization (Placeholder short note)
• Low: Inflammatory markers (Placeholder short note)
• Advanced: Fasciosis grade (Placeholder short note)
• Prolonged: Recovery outlook (Placeholder short note)

Degenerative endpoint

Placeholder: chronic fasciosis reflects failed healing rather than active inflammation.

Placeholder: this stage is degenerative fasciosis, not classic fasciitis inflammation.
