Repair of Large Chondral Defects of the Knee with Autologous Chondrocyte Implantation in Patients 45 Years or Older

Abstract

Our results showed a failure rate of ACI in older patients that is comparable with rates reported in younger patient groups. The procedure is associated with a substantial rate of reoperations, mostly for the arthroscopic treatment of graft hypertrophy, similar to that in younger patients.
