Clinical Evidence - AMIC in the Hip

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 4 months1 and is replaced by native tissue.


Long-Term Advantages of AMIC® Chondro-Gide® vs. MFx Alone

The use of Chondro-Gide® in the hip is well established. Data up to 8 years post-op clearly demonstrates the long-term advantages of AMIC® Chondro-Gide® compared to MFx alone in acetabular defects2,3,4. In a study comparing arthroscopic MFx alone with AMIC® Chondro-Gide®, De Girolamo et al.3,5 investigated 109 patients. Patients with chondral defects in the hip that were associated with FAIs, were treated with AMIC Chondro-Gide® or MFx. There was no significant difference in age or the average defect size between the two patient groups.




A 5-year study by Mancini and Fontana compared the outcome of AMIC® Chondro-Gide® and matrix-induced autologous chondrocyte implantation (MACI) techniques for the treatment of medium sized acetabular chondral defects.5 AMIC offers additional benefits as a 1-step, minimally-invasive procedure that can reduce total treatment time and minimize morbidity.
