NCT03262909

Brief Summary

Multicenter, open-label, controlled, non-randomized, double arm trial with a prospective treatment arm (GelrinC). This study compares the efficacy and safety of GelrinC to a historical control arm (microfracture) in the treatment of cartilage defects in the knee.

Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Age between 18 and 50.
  • Single contained symptomatic lesion located on the femoral condyle of the femur graded as ICRS III or IV with less than 5 mm of bone loss below the subchondral plate.
  • Lesion size between 1 and 5 cm2 post debridement, less than or equal to 2.5 cm in diameter.
  • BMI ≤35
  • Contralateral knee is asymptomatic, stable, fully functional and not medically treated.

You may not qualify if:

  • Presence of an additional grade III or IV symptomatic lesion.
  • Recent Osteochondritis Dissecans within 1 year of baseline visit.
  • Untreated ACL and/or PCL deficiency or Complex ligamentous instability of the knee.
  • Patient is excluded if presenting untreated current meniscal tear or if previous menisci resection was within the last 6 months.
  • Previous tendon repair or ligament reconstruction within the last 6 months.
  • Failed Mosaicplasty or ACI or MACI or any other cartilage repair product.
  • Microfracture performed less than 1 year before baseline visit.
