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 osteotomyor 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.

Clinical Evidence – AMIC® Chondro-Gide® in the Talus

How Chondro-Gide® Works

Chondro-Gide® provides a protective cover and keeps in place cells released from the bone or introduced into a defect. It complements regenerative treatment approaches for chondral and osteochondral lesions. While enveloping the defect and the cells within it during the initial stages of the healing process, Chondro-Gide® resorbs over approximately 1- 4 months11 and is replaced by native tissue.

Chondro-Gide® Successful without Osteotomy

Several studies have shown that Chondro-Gide® can be successfully introduced and placed without osteotomy. Walther et al.12 described the reconstruction of focal cartilage defects in the talus with mini-arthrotomy and Chondro-Gide for ICRS grade III and IV focal cartilage defects of an area of > 1.5 cm2. The researchers reviewed postoperative results of 14 patients for a follow-up period of > 30 months. All showed improved American Orthopedic Foot and Ankle Society (AOFAS) scores, from 50 to 89 points, with equal mobility on both sides of the upper ankle joint. They observed no intraoperative complications. They concluded that AMIC® Chondro-Gide® is a simple procedure. The membrane can be implanted via mini-arthrotomy alone, without osteotomy of the lateral or medial malleolus in almost all cases. They also considered AMIC® Chondro-Gide® to be a cost-efficient 1-step procedure compared to cartilage  reconstruction with in-vitro cultured chondrocytes.

In an analysis of mid-term results, Gottschalk et al.13 found promising results in both 2- and 5-year studies of the patient cohort. The researchers found the greatest improvement in clinical outcomes in the first year post operation. Between the 1- and 5-year follow-up further, but statistically nonsignificant improvement could be observed. Significantly, patients returned to sports at 5 years.

Several authors have reported the advantage of an arthroscopic procedure for the treatment of OCL of the talus. Arthroscopic treatment can reduce surgical trauma, and makes a tibial or fibular osteotomy and subsequent hardware removal unnecessary.14
