Cartilage Regeneration Center: Knee Cartilage Surgery Options

Dr. Broyles offers several knee cartilage surgery options or biologic treatment options for patients with cartilage damage. The right treatment for you depends on several factors including the extent of disease and your ability to travel to Baton Rouge for treatment. 

Biologic Augmented Microdrilling (BAM)

Dr. Broyles' flagship knee cartilage treatment, the BAM procedure involves an outpatient microdrilling surgery, 12 weeks of targeted physical therapy and 12 postoperative stem cell collections and knee injections over 1 year. Eligible patients will be age 60 or younger with a BMI of 35 or less. 

For treatment details, see our Procedure & Recovery page. For background and treatment results, including peer-reviewed techniques and outcomes papers, see our Origins & Research page.

Biologic Injections (PRP, BMAC and/or HA)

A Biologic Injection is a same-day, in-office procedure. Biologic Injections are available for any joint, for patients over age 60 and for patients who do not meet the BMI requirement for BAM surgery.

These biologics have been shown in the literature to protect existing cartilage, reduce pain and inflammation, and slow further cartilage degeneration.

Platelet Rich Plasma (PRP) is a blood product that contains concentrated growth factors. These growth factors provide an optimal environment in the joint for cartilage repair to occur. PRP has been shown to offer a clinical improvement in mild cases of osteoarthritis for 6 months to 1 year. See supporting literature in this case control study and randomized controlled study.

Bone Marrow Aspirate Concentrate (BMAC) - In addition to growth factors, BMAC also includes stem cells, the actual workers needed to perform the cartilage repair. BMAC has been used to treat focal cartilage damage and OA with good to excellent results.

Hyaluronic Acid (HA) is a building block of normal hyaline cartilage and is routinely injected into OA knees.
