Cartilage Preservation vs. Knee Replacement: When Joint Preservation Makes Sense

Posted on: February 11th, 2026 by Our Team

Knee replacement surgery is an effective option for advanced arthritis, but it is not always the first — or best — solution. Many patients with cartilage damage may be candidates for joint preservation procedures that delay or avoid the need for knee replacement altogether.

Understanding the difference between cartilage preservation and knee replacement is essential for making informed decisions about long-term joint health.

Understanding Cartilage Damage

Articular cartilage provides smooth, frictionless motion in the knee. Once damaged, it has limited ability to heal on its own. Untreated cartilage loss can lead to pain, swelling, stiffness, and progressive arthritis.

Not all cartilage damage is the same — and not all patients require joint replacement.

What Is Joint Preservation?

Joint preservation focuses on restoring or protecting cartilage while maintaining the patient’s native joint. These procedures are particularly valuable for:

• Younger or middle-aged patients
• Active individuals (regardless of age!)
• Patients with localized cartilage defects
• Patients without advanced, diffuse arthritis

Common Cartilage Preservation Options

• MACI (Matrix-Induced Autologous Chondrocyte Implantation)
• Osteochondral Allograft Transplantation
• Meniscus Preservation or Transplantation
• Cartiheal Agili-C
• Alignment Correction (Osteotomy)

These techniques aim to restore joint mechanics and slow degenerative progression.

When Knee Replacement Is Appropriate

Total knee replacement is generally recommended for patients with:

• Severe, end-stage arthritis
• Diffuse cartilage loss throughout the joint
• Significant deformity or stiffness
• Pain unresponsive to non-operative treatment

While highly successful, knee replacement has limitations, especially for younger or highly active patients.

Choosing the Right Path

The decision between joint preservation and knee replacement depends on many factors, including age, activity level, alignment, cartilage health, and patient goals. A thorough evaluation by a specialist experienced in both approaches is critical.
