Primary Outcome Measures:
  • redaction in healing time and recurrence [ Time Frame: 1 year ]

Estimated Enrollment: 50
Study Start Date: January 2008
Study Completion Date: March 2009
Primary Completion Date: February 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Placebo Comparator: 2
Drug: placebo
injection of 6 cc of saline into injured area
Other Name: saline 0.9% NaCl
Experimental: 1
Plasma Rich in Growth Factors (PRGF)
Biological: Plasma Rich in Growth Factors (PRGF)
US guided IM injection 3-6mg
Other Name: platelet-derived preparation rich in growth factors

Detailed Description:
Autologous platelet-rich matrices may aid in the healing of ligaments & tendons by promoting and accelerating tissue healing because of the release of growth factors including transforming growth factor (TGF)-beta1 and platelet-derived growth factor (PDGF) from platelet alpha-granules.
