ACI Summary
Charts adapted from Peterson , et al.
Your results may vary, but ACI offers a chance to save further knee deterioration in selected cases. For improved results some cases require corrective bony realignments called osteotomies. That means in some patients, the tibia may need to be cut to realign forces on the knee joint or the patella attachment may need to be elevated to take pressure off the kneecap. Stability is also very important. If the anterior cruciate ligament has been torn, it needs to be reconstructed to stabilize the knee prior to or in concurrence with ACI. The result is that the implant operation can take from 2 hours for a simple singular lesion to as much as 4-6 hours for complicated lesions with a bony osteotomy.
