An innovative biological cartilage repair method for treating chondropathies of the acetabulum and the femoral head in the hip

  • A minimally invasive technique allows shorter hospitalisation and faster rehabilitation
  • Based on microfracturing, the established first-line treatment
  • Cost effective one-step procedure for the treatment of lesions >2 cm2, not suitable for microfracture alone
  • Protection of blood clot in a «bioactive» chamber provided by the Chondro-Gide® matrix
  • Ad hoc usage and off-the-shelf supply of Chondro-Gide®, the leading natural collagen matrix for cartilage regeneration

Chondropathies of the acetabulum and the femoral head are a frequent cause of pain and functional limitation. Moreover, if cartilage defects in the hip are not adequately repaired, progression of the damage and arthritic changes may occur. Several treatment options are available to repair chondral lesions in the hip including debridement, microfracture, autologous chondrocyte implantation (ACI) and now the AMIC® arthroscopic hip technique.

Arthroscopic procedures are more desirable than open surgery because they are less invasive and hence reduce the risk of complications, such as infections and avascular necrosis of the femoral head and allow shorter recovery time, resulting not only in lower overall treatment cost but also higher patient satisfaction.


  • Grade III or IV chondral lesions (Outerbridge classification) on acetabulum or femoral head
  • AMIC® on acetabulum and microfracture on femoral head for kissing lesions
  • Lesion size of 2–8 cm2
