The objective of this clinical trial is to evaluate both the safety and efficacy of the ReNu™ injection on pain and inflammation in subjects diagnosed with plantar fasciitis as compared to a Corticosteroid Injection which is considered standard of care.

This is a two (2) arm evaluation in 150 subjects with plantar fasciitis. Patients will be treated with ReNu™(study treatment) or Corticosteroids (control).

At each follow-up visit, concomitant medications and adverse events shall be collected from each subject, and each subject shall complete following questionnaires:

• AOFAS Ankle-Hindfoot Score (AOFAS-AHS)
• Visual Analog Score (VAS)
• Single Answer Numeric Evaluation (SANE)
• Subject Satisfaction Score (at the 6 Month Follow Ups ONLY)

The subjects will be assessed at Baseline (pre-injection) using these scales and again at all subsequent study follow-up visits.
