Arthroscopic MACI: A New Milestone in Minimally Invasive Cartilage Restoration

Cartilage damage can cause ongoing joint pain, swelling, and loss of mobility—and it rarely heals on its own. Advances in orthopedic care are now making it possible to restore damaged cartilage while preserving the natural joint. One of the most exciting developments is arthroscopic MACI (Matrix-Induced Autologous Chondrocyte Implantation).

Recently, Dr. David Goodwin became one of the first surgeons to perform arthroscopic MACI, a minimally invasive approach that represents a significant step forward in cartilage repair and joint preservation.

What Is Arthroscopic MACI?

MACI is an advanced cartilage restoration procedure that uses a patient’s own cartilage cells to repair areas of damaged cartilage. These cells are grown in a lab and placed on a specialized scaffold, which is implanted into the joint.

With arthroscopic MACI, the procedure is performed using small incisions and a minimally invasive technique, reducing disruption to surrounding tissue.

Benefits of Arthroscopic MACI

Compared to traditional open procedures, arthroscopic MACI offers several patient-focused advantages:

• Smaller incisions

• Less surgical trauma

• Preservation of healthy tissue

• Support for a smoother recovery

• Focus on joint preservation rather than replacement

Who May Be a Candidate?

Arthroscopic MACI may be an option for patients with focal cartilage damage who experience pain, swelling, or limited function and want to protect their natural joint. A comprehensive evaluation is required to determine if cartilage restoration is appropriate.

Advancing Joint Preservation Care

Innovations like arthroscopic MACI reflect the continued evolution of orthopedic surgery toward less invasive, more patient-centered solutions. At Arthritis & Sports, our focus remains on helping patients return to movement, function, and quality of life—guided by our philosophy: Patients First. Improve Lives.

Frequently Asked Questions About Arthroscopic MACI

What does MACI stand for?

MACI stands for Matrix-Induced Autologous Chondrocyte Implantation, a procedure that uses your own cartilage cells to repair damaged cartilage.

Is arthroscopic MACI less invasive than traditional MACI?

Yes. Arthroscopic MACI is performed through small incisions, which reduces surgical trauma compared to traditional open techniques.

How long is recovery after arthroscopic MACI?

Recovery varies by patient and defect size, but minimally invasive techniques are designed to support a more efficient rehabilitation process.

Can MACI help delay joint replacement?

For appropriate candidates, cartilage restoration procedures like MACI may help preserve the natural joint and delay or prevent the need for joint replacement.
