Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Age 21 years and older
* Cartilage lesion(s) located in the facets of the patella that have failed prior therapy (conservative or surgical)
* Symptomatic lesions classified as ICRS grade 2, 3, or 4
* Lesion size may not exceed 3.1 cm2 and must be circumscribed by a 15 mm or 20 mm circle of normal or nearly normal (ICRS Grade 0 or 1) cartilage, with an overall depth less than 4 mm from the articulating surface
* Subchondral bone quality sufficient to support the implant
* Understanding and willingness to comply with the post-operative rehabilitation instructions and follow-up visits.

Exclusion Criteria

* Body mass index (BMI) ≥ 35
* Generalized degenerative or autoimmune arthritis
* Gout
* Uncorrected chronic malalignment of the patella (may be corrected at the same time as the implantation of the BioPoly device).
* Uncorrected ligamentous instability (may be corrected at the same time as the implantation of the BioPoly device).
* Kissing lesion on femur
* More than one implant required to accommodate lesion
* Allergy to ultra-high molecular weight polyethylene (UHMWPE), or hyaluronan/ hyaluronic acid (HA)
* Use with opposing articulating femoral components
* Any concomitant painful or disabling disease of the spine, hips, or lower limbs that would interfere with evaluation of the afflicted knee
* Pregnant, prisoner, vulnerable population, or unable to provide informed consent.
