Primary Outcome Measures:
  • To evaluate the safety of Augment Bone Graft plus Allograft for treatment of osteochondral defects of the knee. [ Time Frame: 12 months ]
    Collection of related adverse events

Secondary Outcome Measures:
  • To utilize Magnetic Resonance Imaging to evaluate device integrity and surgical treatment of osteochondral defects of the knee. [ Time Frame: 12 months ]
    Assess healing and bone formation from radiological reports

Enrollment: 1

Study Completion Date: August 2012
Primary Completion Date: August 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Bone Graft
Single Arm.. Augment Bone Graft for Osteochondral Defects
Device: Augment Bone Graft
Augment Bone Graft physically fills bone defects by providing a biocompatible scaffold for new bone formation.The material is comprised of a matrix of beta tricalcium phosphate and a highly purified recombinant human platelet-derived growth factor.
Other Name: Bone Graft

Detailed Description:
Subjects will be 18 to 40 years with an osteochondral defects of the knee.They will be candidates for allograft and Augment Bone Graft will be added to the procedure. The safety of Augment Bone Graft plus allograft for osteochondral defects of the knee will be evaluated by type, frequency, severity and relatedness of adverse events to the device for a minimum of 24 weeks.Magnetic Resonance Imaging will be performed at 1,12 and 42 weeks to evaluate device integrity and surgical treatment of osteochondral defects. Computed tomography will be done at week 1 and week 24 to determine the healing status of the osteochondral defect.

Ages Eligible for Study:   18 Years to 40 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
