Knee pain caused by cartilage damage can make everyday movement difficult, from walking and climbing stairs to staying active. For patients looking to delay or avoid more invasive procedures, microfracture knee surgery offers a minimally invasive option to stimulate the body’s natural healing process. At Ortho Sport & Spine Physicians, with locations in Atlanta and across the country, we provide advanced orthopedic solutions designed to restore mobility and reduce pain.
What Causes Cartilage Damage in the Knee?
Cartilage is the smooth, protective tissue that covers the ends of bones in your joints. It allows for pain-free movement and absorbs shock during activity. However, cartilage does not heal easily because it lacks its own blood supply.
Cartilage damage can occur due to:
- Sports injuries or trauma
- Repetitive stress on the joint
- Aging and wear-and-tear
- Degenerative conditions like osteoarthritis
Studies show that over 60% of knee arthroscopy patients have some degree of cartilage damage, making it a common source of pain and dysfunction.
What Is Microfracture Knee Surgery?
Microfracture surgery is a minimally invasive procedure designed to stimulate new cartilage growth in areas where it has been damaged or lost.
During the procedure:
- Loose or damaged cartilage is first removed
- Small holes, called microfractures, are created in the underlying bone
- These holes penetrate the hard outer layer of bone
This process allows access to deeper bone layers that have a richer blood supply. The blood and healing cells released from this area form a clot, which eventually develops into new cartilage-like tissue.
How the Procedure Promotes Healing
The surface layer of bone is dense and has limited blood flow, which is why cartilage damage does not heal on its own. By creating microfracture holes, surgeons allow the deeper, more vascular bone to reach the surface.
This leads to:
- Increased blood flow to the damaged area
- Release of stem cells and growth factors
- Formation of new cartilage tissue
While the new tissue is not identical to the original cartilage, it can significantly improve joint function and reduce pain.
Who Is a Good Candidate?
Microfracture surgery is often recommended for patients with localized cartilage damage who want to preserve their natural joint.
Ideal candidates typically include:
- Younger or active individuals
- Patients with small to moderate cartilage defects
- Those without advanced arthritis
- Individuals seeking to delay joint replacement
Clinical outcomes show that many patients experience meaningful improvement in pain and function, particularly when combined with proper rehabilitation.
Benefits of Microfracture Surgery
This procedure offers several advantages compared to more invasive treatments.
Key benefits include:
- Minimally invasive arthroscopic technique
- Shorter recovery time compared to major surgery
- Stimulation of natural healing processes
- Reduced pain and improved joint mobility
Research indicates that microfracture surgery can provide significant symptom relief in up to 75–80% of appropriately selected patients.
Recovery and Rehabilitation
Recovery from microfracture surgery requires a structured rehabilitation plan to protect the healing tissue and encourage proper growth. Patients can expect:
- Limited weight-bearing initially
- Physical therapy to restore strength and mobility
- Gradual return to activity over several months
Following your physician’s guidance is essential for achieving the best possible outcome.
