Autologous chondrocyte implantation (ACI) is contra-indicated in a joint rendered unstable by a ruptured anterior cruciate ligament (ACL). We present our experience of ACI repair with ACL reconstruction Patients underwent arthroscopic examination and cartilage harvesting of the knee. A second operation was undertaken approximately six weeks later to repair the ruptured ACL with hamstring graft or Bone patella-Bone (BPB) and to implant the chondrocytes via formal arthrotomy. Three groups were assessed: Group 1: Simultaneous ACL Reconstruction and ACI; Group 2: Previous ACL Reconstruction with subsequent ACI repair; Group 3: Previously proven partial or complete ACL rupture, deemed stable and not treated with reconstruction with ACI procedure subsequently. Patients then underwent a graduated rehabilitation program and were reviewed using three functional measurements: Bentley functional scale, the modified Cincinnati rating system, and pain measured on a visual analogue scale. All patients also underwent formal clinical examination at review.Introduction
