Study Arms (2)

Neocartilage Implant

ACTIVE COMPARATOR

Neocartilage Implant surgically implanted and affixed to subchondral bone using commercial fibrin during mini-open knee arthrotomy.

Biological: Neocartilage Implant/DeNovo® ET (Engineered Tissue Graft)

Microfracture

OTHER

Standard of care cartilage repair technique.

Other: Microfracture

Interventions

The Neocartilage Implant is a cartilage repair technology cultured from juvenile human cartilage cells.

Also known as: RevaFlex
Neocartilage Implant

Marrow stimulation using the microfracture technique; performed arthroscopically

Also known as: marrow stimulation
Microfracture

Eligibility Criteria

Age18 Years - 60 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Male or Female between the ages of 18 and 60
  • (1) or (2) articular cartilage lesions of the distal femur ranging in no more than 5 cm2 each
  • Ipsilateral knee compartment has intact menisci (or meniscectomized remnant with \> 5mm wide rim) and stable ligaments in the affected knee
  • months out from initiation of conservative non-surgical management (e.g.hyaluronic acid injection, activity modification) or previous minimal surgical intervention (e.g., arthroscopic lavage, debridement) or 12 months out from marrow stimulation for this condition

You may not qualify if:

  • Generally, if a potential participant meets any of the following criterions, they will not be eligible for this study. Additionally, more criteria will be evaluated to confirm eligibility as this list is not a complete list of criteria.
  • Osteoarthritis
  • Rheumatoid arthritis
  • History of septic or reactive arthritis
  • Gout or a history of gout or pseudo-gout in the affected knee
  • Osteochondritis dissecans or osteochondral lesions of the knee with bone loss \> 6mm deep
  • Bipolar articular cartilage involvement (or kissing lesions) of the ipsilateral compartment (i.e., \> than ICRS Grade 2 on the opposing articular surface)
  • Associated damage to the underlying subchondral bone requiring an osteochondral graft
  • Is pregnant or breast-feeding
  • Has a BMI \> 35 (kg/m2)
  • Has prior total meniscectomy of either knee
  • Has received, within the past three months, intra-articular hyaluronic acid therapy, or steroid therapy
  • Has more than two clinically relevant chondral lesion(s) on the index knee
