3. The subject is independent, ambulatory, and can comply with all post-operative evaluations and visits.
4. The subject is at least nineteen (19) years of age and considered to be skeletally mature.
5. The subject has a combined bone and cartilage defect as determined by an MRI.
6. The patient has a stable ankle joint on history and has similar ligament stability with the opposite ankle.
7. The subject has less than 15 degrees of hindfoot valgus and 5 degrees of hindfoot varus.
8. The subject has a chronic defect not secondary to acute trauma within the last 6 months.
9. The patient (if having suffered a fracture) has no residual deformity of the tibia, fibula or syndesmosis.
10. The subject has a BMI of ≤ 40 kg/m².

Exclusion Criteria:
1. The subject has over 15 degrees of hindfoot valgus or 5 degrees of hindfoot varus.
2. The subject has an isolated OCD with dimensions greater than 2.0 cm2 on an MRI assessment.
3. The subject has an allergy to yeast-derived products.
4. The subject has implanted metallic devices (cardiac pacemakers, insulin pumps, and nerve stimulators), medically implanted clips, or other electronically, magnetically or mechanically activated implants that would contraindicate an MRI scan of the foot.
5. The subject has claustrophobia that would inhibit their ability to undergo an MRI scan of the foot.
6. The subject has tested positive or has been treated for a malignancy in the past, is suspected of having a malignancy, or is currently undergoing radiation or chemotherapy treatment for a malignancy anywhere in the body, whether adjacent to or distant from the proposed BioCartilage® site.
7. The subject is physically or mentally compromised (e.g., currently being treated for a psychiatric disorder, senile dementia, Alzheimer's disease, etc.), to the extent that the investigator judges the subject to be unable or unlikely to remain compliant to follow-up.
8. The subject is a prisoner, or is known or suspected to be transient.
9. The subject has documented evidence of a history (e.g. liver testing) of drug/alcohol abuse within the 12 months prior to screening for study entry.

13. The subject's condition is bilateral and surgery is scheduled or to be scheduled over the course of this trial for both feet.

15. The subject requires a concomitant hindfoot fusion or has had a hindfoot fusion for hindfoot arthritis or deformity.
16. The subject is undergoing any concomitant surgery that may invalidate the outcome scores such as forefoot surgery or fusions, tendon transfers or ligament reconstructions. Heel cord lengthening is permitted.
