Matrix-Associated Cartilage Implantation (MACI) in Boca Raton, Boynton Beach & Delray Beach, FL
Matrix-Associated Cartilage Implantation (MACI) is an advanced cartilage restoration procedure designed to treat symptomatic cartilage defects in the knee. This innovative technique uses a patient's own cartilage cells, which are grown and placed onto a specialized collagen membrane that is implanted into the damaged area to help restore cartilage and improve joint function. MACI may be an effective treatment option for active individuals with focal cartilage injuries who wish to preserve their natural joint and maintain an active lifestyle. Dr. William P. Toole is a board-certified, fellowship-trained orthopedic sports medicine specialist providing advanced cartilage restoration and joint preservation treatments for patients throughout Boca Raton, Boynton Beach, and Delray Beach. Through comprehensive evaluation and individualized treatment planning, Dr. Toole helps patients determine whether MACI may be an appropriate solution for their cartilage injury and long-term joint health goals.
Introduction
Matrix-Induced autologous chondrocyte implantation is an innovative, FDA-approved cartilage restoration procedure that uses your own cells to repair cartilage defects in your knee. It can alleviate knee pain, help you regain function and may even delay or prevent arthritis.
Disease Overview
Knee cartilage injuries may be caused by repetitive actions or a traumatic event such as a fall or a direct blow resulting in knee pain, swelling, and restricted range of motion. When compared to muscle or bone, cartilage has a very poor blood supply and injuries tend to heal very slowly and may even get worse with time. When conservative treatments or other options fail to resolve your symptoms, MACI maybe your best option to return to what you enjoy.
Who is an Ideal Candidate?
This procedure is recommended for young patients with:
- A single lesion under 2 cm
- Healthy underlying bone
Procedure
The steps involved in MACI include:
- Obtaining the Biopsy: A small biopsy of healthy cartilage is performed from a non-weight-bearing portion of the knee.
- Biopsy Processing: The biopsy is sent to a state-of-the-art processing facility where chondrocytes, the cartilage-producing cells, are extracted from the biopsy and inserted onto a layer of collagen, a type of protein.
- Chondrocyte Regeneration: The embedded chondrocytes regenerate within the collagen matrix to form implant tissue that can be used to fill the cartilage defect. The process usually takes about 6 weeks.
- MACI Delivery: The matrix-induced autologous chondrocyte implant is then delivered at the appropriate time to your surgeon for the implant procedure.
- MACI Implanted: Your surgeon will then shape the collagen matrix to cover your cartilage defect and surgically implant it into your knee.
Advantages
The benefits of this approach include:
- No danger of tissue rejection
- The implanted material may further stimulate the production of cartilage
Risks and Complications
Complications with MACI are rare and include:
- Tendonitis
- Arthralgia or joint pain
- Joint swelling
- Cartilage injury
- Osteoarthritis
Contraindications
This procedure should be avoided in cases of:
- Hypersensitivity to collagen
- Severe osteoarthritis
- Inflammatory joint disease
- Blood coagulation disorders
- Knee surgery in the past 6 months

MACI FAQs
What is Matrix-Associated Cartilage Implantation (MACI)?
MACI is an advanced cartilage restoration procedure that uses a patient's own cartilage cells to repair damaged cartilage within the knee. Healthy cartilage cells are harvested, expanded in a laboratory, and placed onto a collagen membrane that is later implanted into the cartilage defect.
What conditions can MACI treat?
MACI is primarily used to treat symptomatic focal cartilage defects in the knee. These injuries may result from sports injuries, trauma, repetitive stress, or other causes of cartilage damage.
How does MACI differ from other cartilage restoration procedures?
Unlike some cartilage repair techniques that stimulate the formation of replacement tissue, MACI utilizes the patient's own cartilage cells in an effort to restore more natural cartilage characteristics within the damaged area.
Who is a candidate for MACI?
Candidates are typically active individuals with localized cartilage defects who have persistent symptoms despite conservative treatment. Factors such as age, activity level, defect size, knee alignment, ligament stability, and overall joint health are considered during evaluation.
How is the MACI procedure performed?
MACI is generally completed in two stages. First, a small sample of healthy cartilage is collected arthroscopically. The cartilage cells are then expanded in a laboratory and placed onto a collagen scaffold. During a second procedure, the implant is secured into the cartilage defect to encourage tissue regeneration.
What symptoms may indicate a cartilage defect?
Patients with cartilage injuries often experience knee pain, swelling, stiffness, catching sensations, reduced range of motion, and discomfort during physical activity. Symptoms may worsen over time if left untreated.
What is recovery like after MACI?
Recovery involves a structured rehabilitation program designed to protect the implant while gradually restoring strength and mobility. Patients typically participate in physical therapy and follow activity restrictions during the healing process.
How long does it take to recover from MACI surgery?
Recovery timelines vary based on the size and location of the cartilage defect, as well as the patient's progress during rehabilitation. Full recovery and return to high-level activities often require several months.
Will I need physical therapy after MACI?
Yes. Physical therapy is a critical part of the recovery process. Rehabilitation focuses on restoring joint motion, improving strength, optimizing movement patterns, and safely progressing activity levels.
Can athletes return to sports after MACI?
Many athletes and active individuals are able to return to sports following successful MACI treatment and rehabilitation. Return-to-sport decisions are based on healing progress, strength recovery, functional testing, and sport-specific demands.
Can MACI help delay knee replacement surgery?
For appropriate candidates with focal cartilage injuries, MACI may help preserve the natural knee joint, improve symptoms, and potentially delay the need for more extensive procedures such as knee replacement surgery.
How is a cartilage defect diagnosed?
Diagnosis typically includes a physical examination, review of symptoms, and imaging studies such as MRI scans, which provide detailed visualization of cartilage injuries and associated joint conditions.
