Cartilage Restoration Program

Advanced Knee Cartilage Repair, and Joint Preservation

If knee pain, swelling or a sports injury is keeping you from doing the activities you love, our Cartilage Restoration Program offers advanced treatments designed to repair damaged cartilage, preserve your natural joint and help you return to an active lifestyle. Our sports medicine specialists provide personalized care using the latest evidence-based cartilage restoration techniques, often helping patients delay or avoid joint replacement.

What Is Cartilage?

Articular cartilage is the smooth protective tissue covering the ends of bones inside a joint. It allows bones to glide smoothly while absorbing shock during walking, running and sports. Because cartilage has a very limited blood supply, it does not heal well on its own. Untreated damage can lead to pain, swelling, stiffness and progressive arthritis.

What Causes Cartilage Damage?

Cartilage injuries can happen suddenly during sports or develop gradually over time from normal wear and tear. Our specialists evaluate the underlying cause of your symptoms to recommend the most effective treatment.

Common causes include:

Sports injuries
ACL and ligament injuries
Meniscus tears
Knee trauma
Previous knee surgery
Repetitive wear and tear
Early arthritis

Could Cartilage Damage Be Causing Your Knee Pain?

Cartilage damage doesn't always cause symptoms right away. As the injury progresses, you may notice pain, swelling or difficulty with everyday activities. Early evaluation can help prevent further joint damage.

Symptoms patients commonly experience:

  • Knee pain during activity
  • Swelling after exercise
  • Stiffness
  • Catching or locking
  • Clicking or grinding
  • Reduced range of motion
  • Difficulty climbing stairs, squatting, running or participating in sports.

What Conditions Do We Treat?

Our Cartilage Restoration Program cares for patients with a wide range of cartilage injuries and joint preservation conditions. Whether your injury is caused by sports, trauma or early joint degeneration, we develop a treatment plan tailored to your goals.

We commonly treat:

  • Focal cartilage defects
  • Sports-related cartilage injuries
  • Osteochondritis dissecans (OCD)
  • Cartilage injuries associated with meniscus tears
  • Post-traumatic cartilage damage
  • Early cartilage wear and degeneration
  • Complex knee cartilage injuries

Who Is a Candidate?

You may benefit from cartilage restoration if you are active, have persistent knee pain, have isolated cartilage damage, want to return to sports or have been told you are too young for a knee replacement. Following a comprehensive evaluation, our specialists will determine the most appropriate treatment.

Comprehensive Evaluation

Your evaluation includes a medical history, physical examination, advanced imaging when needed, assessment of alignment, ligament stability and meniscal health, and discussion of your activity level and goals. We treat the entire joint—not just the cartilage injury.

Non-Surgical Treatment

Many patients improve with activity modification, physical therapy, anti-inflammatory medications, bracing and image-guided injections. While these treatments can relieve symptoms, they do not regenerate damaged cartilage.

Advanced Cartilage Restoration Procedures

When surgery is appropriate, we offer advanced joint preservation procedures designed to restore cartilage and preserve the natural joint, including::

  • Microfracture – stimulates the body's healing response.
  • Osteochondral Autograft Transfer (OATS) – transfers healthy cartilage from another area of your knee.
  • Osteochondral Allograft Transplantation – replaces damaged cartilage with donor tissue.
  • Matrix-Induced Autologous Chondrocyte Implantation (MACI) – uses your own cartilage cells to repair damaged tissue.
  • Autologous Chondrocyte Implantation (ACI)
  • Meniscal Transplantation
  • High Tibial or Distal Femoral Osteotomy (HTO/DFO)
  • Tibial Tubercle Osteotomy (TTO)

These procedures are often combined with ligament reconstruction, meniscus preservation or alignment correction to optimize outcomes.
