Brief Summary:
Treatment of osteochondral lesion of Talus with a devitalized viro-inativated sterile osteochondral graft. To avoid having to harvest autograft material from the knee, a processed allogeneic osteochondral can be used instead autograft. The surgical technique is to implant in the osteochondral defect one to three products in the defect.

Condition or disease Intervention/treatment Phase
Talus Osteochondral Defect Other: processed osteochondral allograft Phase 1 Phase 2

Primary Outcome Measures :
  1. Determine the improvement in ankle function based on the OMAS at 24 months [ Time Frame: 3 months, 6 months, 12 months, 18 months, 24 months ]

Secondary Outcome Measures :
  1. Clinical and functional improvement of the ankle by AOFAS score [ Time Frame: 3 months, 6 months, 12 months, 18 months,24 months ]
    questionnaire and clinical evaluation

  2. Impairment improvement by FASS ( foot and ankle severity score) [ Time Frame: 3 months, 6 months, 12 months, 18 months,24 months ]

  3. Evaluate osteochondral graft integration with imaging [ Time Frame: 12 months, 18 months, 24 monts ]
    - CT-scan at 12 months, MRI 18- 24 months

  • Osteochondral lesion > Anderson Grade I (MRI)
  • 1 to 3 cm2 lesion
  • Presence of disabling and clinically meaningful symptoms (subjective OMAS < 50)
