Trial Title: AS: Ankle Spacer for Talar Osteochondral Defects

Study Design Characteristics:
- Allocation: None
- Intervention Model: SINGLE_GROUP
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: NONE
- Phase: None
- Number of Arms: 1.0

Eligibility Criteria:
Inclusion Criteria:~* age ranging from 18 to 80 years~* talar osteochondral defect (multiple degenerative talar cysts present, and/or prior failed surgical treatment and/or multiple defects and/or large (\>15mm))~* willing to receive surgical implantation of the Ankle Spacer~* has been informed of the nature of the study and provided written consent~* The subject and treating physician agree that the subject will return for all required post-procedure follow-up visits~* failed previous conservative treatment~* complaints for at least 6 months~Exclusion Criteria:~* -severe ankle malalignement.(\> 5° varus/valgus).~* fracture \< 6 months - tendinitis - diabetes mellitus / rheumathoid arthritis~* advanced osteoporosis~* grade two or higher (Kellgren-Lawrence-Score) ankle joint degeneration on the tibia side.~* any ankle deformation that does not allow proper rasping of the cartilage and/or proper seating of the desired sized implant, as described in the surgical technique.~* blood supply limitations and previous infections, which may retard healing.~* foreign-body sensitivity. Where material sensitivity is suspected, appropriate tests should be made and sensitivity ruled out prior to implantation.~* active infection or blood supply limitations.~* conditions that tend to limit the patient's ability or willingness to restrict activities or follow directions during the healing period, including severe neuro-arthropathy.~* pathological conditions, such as insufficient quantity or quality of bone (e.g., cystic changes or severe osteopenia), which may compromise implant fixation.~* currently participating in an investigational drug or another device study that clinically interferes with the current study endpoints.~* Inability to be brought back to the surgery site for long term follow-up evaluations or the subject is unwilling to fill out the appropriate evaluation forms~* adiposity grade I (BMI \> 30 kg/m2)
