Ages Eligible for Study: | 18 Years to 60 Years (Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
Generally, the following inclusion criteria must be met, however, this is not a complete list.
- 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
- 3 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
Exclusion Criteria:
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
