About this trial

This is an interventional treatment trial for Knee Injury focused on measuring allograft, knee injury, cartilage injury, Osteochondral defects in the articular femoral cartilage

Eligibility Criteria

Inclusion Criteria:

  • 18 years of age or older
  • Skeletally mature
  • Have one symptomatic score International Cartilage Repair Score (ICRS) grade 3a, 3b, 3c, 3d, 4a, 4b articular cartilage lesion less than 2.5 cm involving the Medial Femoral Condyle (MFC) or Lateral Femoral Condyle (LFC). Symptoms must include pain, pain with weight bearing and squatting, locking of joints, and/or swelling

Outcomes

Primary Outcome Measures

The Knee Injury and Osteoarthritis Outcome Score (KOOS) at 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.

Secondary Outcome Measures

Current Health Assessment
Evaluation on the Current Health Assessment at 24 months. Scores are transformed to a 0-100 scale, with zero representing a self-graded perception of extremely poor health and 100 representing no health problems. Scores between 0 and 100 represent the percentage of total possible score achieved.
Lysholm With Tegner Score
The Tegner activity scale was designed as a score of activity level to complement other functional scores (eg the Lysholm knee score) for patients with ligamentous injuries. The instrument scores a person's activity level between 0 and 100 where 0 is 'on sick leave/disability' and 100 is 'participation in competitive sports at a full, unhindered level.
International Knee Documentation Committee (IKDC) at 24 Months.
The International Knee Documentation Committee 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.
MRI Evaluation Score
MRI images were graded by a radiologist with regard to the incorporation of the CR graft in both the cancellous and cortical portions of the bone at the graft site. The raw scores were converted to an index scale form 0 to 100, with 0 representing failure of the graft to incorporate and 100 representing complete incorporation of the graft.
