AMIC® Chondro-Gide® in the Talus
Chondral and Osteochondral Lesions (OCL) of the ankle are common and increasingly recognized sources of persistent ankle pain. Most osteochondral lesions of the talus (OLTs) are due to trauma and repetitive microtrauma.1 About 50% of ankle sprains and up to 73% of ankle fractures result in cartilage injury and can cause symptoms.2
Bone Marrow Stimulation Recommended for OCL <1 cm2
Ramponi et. al.3 recommended that bone marrow stimulation techniques should be reserved for OCL < 1 cm2. The 1 cm2 threshold was also supported during a 2017 consensus meeting of the International Society on Cartilage Repair of the Ankle (ISCRA). To view these and other consensus statements, visit the ON Foundation website.
ISCRA defined the ideal size guidelines for bone marrow stimulation as a diameter of < 10 mm, an area of < 100 mm2, and a depth of < 5 mm.4 Bone grafting may be considered for a depth of > 3 mm. Based on current literature, the consensus recommendation supports the use of a scaffold to complement bone grafting.5
AMIC® Chondro-Gide® for Effective Cartilage Repair
AMIC® Chondro-Gide® is a minimally-invasive 1-step procedure that uses bone marrow stimulation combined with Chondro-Gide to repair cartilage defects of all sizes. It can be performed either by osteotomy6 or mini-open surgery7.
Developed by Geistlich Surgery in collaboration with leading surgeons in Europe, AMIC® Chondro-Gide® is an effective and cost-effective treatment7 for repairing damaged cartilage , alleviating or preventing pain, and slowing the progression of damage.
