简要总结

The objective of this study is to determine how effective a plug made out of human bone (called "CR-Plug") will be in the treatment of smaller, focal defects (like the injury the patient has to their knee).

详细描述

The main objective of this double arm study is to test the ability of an allograft plug to provide "successful" repair of less than (<) 2.5 cm2 osteochondral defect in a low-load-bearing femoral condyle region, and a high-load-bearing femoral-condyle region.

结局指标

主要结局

Knee Injury and Osteoarthritis Outcome Score (KOOS

时间窗: 24 months

The outcome at 24 months as measured by the Knee injury and Osteoarthritis Outcome Score (KOOS). Scores are transformed to a 0-100 scale, with zero representing extreme knee problems and 100 representing no knee problems as common in orthopaedic scales and generic measures. Scores between 0 and 100 represent the percentage of total possible score achieved.

次要结局

  • Magnetic Resonance Imaging (MRI) Results(24 months)
  • Current Health Assessment (CHA)(24 months)
  • IKDC Assessment(24 months)
  • Lysholm Score at 24 Months(24 months)
