Who Is a Candidate for Cartilage Repair Surgery?
MACI works best for patients with a defined cartilage defect in the knee, typically caused by injury rather than widespread joint degeneration. Good candidates are generally active, have tried conservative treatment without enough improvement, and have healthy surrounding cartilage and bone. Dr. Ayzenberg will review your MRI and do a physical exam to confirm whether MACI or another approach makes more sense for your specific case.
If you've been told you have a cartilage lesion and are wondering what your options are, this is the conversation to have early. Cartilage doesn't heal on its own. The longer a defect sits untreated, the more the surrounding joint tissue takes on the stress.
How MACI Compares to Other Cartilage Treatments
There are several cartilage repair options available, including microfracture and osteochondral grafting. MACI stands apart because it uses your own cells and gives the surgeon precise control over where the membrane is placed, even in larger defects. Microfracture is faster but produces fibrocartilage, which is a weaker substitute for the original tissue. MACI produces hyaline-like cartilage, which is closer to what your knee was built with.
Dr. Ayzenberg also offers stem cell therapy for patients who aren't surgical candidates yet or who want to explore non-surgical options first. The right path depends on the size and location of your defect, your age, and how the joint looks overall.
