Surgeons who perform the MACI knee procedure will see many different knee cartilage repair case studies cross their desks. Dr. Deryk Jones of Ochsner Sports Medicine Institute shares a recent case.
Meet the Patient
- An active male in his mid-30s is a retail worker and former runner.
- He spends plenty of time on his feet with recurrent repetitive injuries to his knee.
- Discussing his condition with Dr. Jones, he chooses MACI to treat his knee cartilage damage.
- After MACI surgery and rehabilitation, he makes his return to running, ultimately training for a half marathon.
A Situational Breakdown of the Patient’s Injury
The patient’s X-rays showed a few different challenges:
- A cystic formation on the right knee.
- A mechanical axis transmitting through the osteochondral lesion site that had previously been treated by an osteochondral allograft (OCA) procedure when there was no significant defect.
- An MRI also revealed a failed “snowman technique” with three large plugs. When he met Dr. Jones, the patient still experienced some pain but had continuous range of motion.
The Approach to Surgery
Following the initial arthroscopy, Dr. Jones proceeded with surgery and took a minimally invasive approach:
- He applied a medial subvastus approach to the MFC paired with drilling of the base lesion to create blood flow.
- He completed a concomitant MACI implantation using the “sandwich technique.”
