Top Cartilage Restoration Procedures in San Francisco
Cartilage damage can make everyday movements painful and limit your ability to stay active. Thanks to advances in orthopedic care, several specialized procedures now offer real hope for restoring joint health and getting you back to the activities you love.

When the smooth, protective cartilage in your knee, ankle, or shoulder becomes damaged, even simple movements can become painful challenges. This slick tissue, which cushions our joints during every step, throw, and pivot, lacks blood vessels that would normally help healing. This is reality for 27 million Americans who suffer from cartilage damage severe enough to cause pain and limit function.
While your body can't repair cartilage naturally, remarkable medical advances have created pathways to restore joint health. Specialized procedures like Osteochondral Autograft Transfer System (OATS) and other treatments now offer targeted solutions for athletes, active adults, and anyone with joint injuries. These regenerative techniques vary in approach and application, with specialists selecting the most appropriate method based on the size, severity, and location of your specific cartilage defect.

What Causes Cartilage Damage and When Is Cartilage Restoration Needed?
Cartilage loss or damage typically results from sudden sports injuries like:
Twisting a knee during sports like basketball or soccer
Direct trauma from falls or accidents
Repetitive stress from activities like running
The early stages of arthritis
When cartilage breaks down, patients experience tell-tale symptoms:
Joint pain that worsens during activity
Noticeable joint swelling after use
Morning stiffness of the joint that improves with movement
Difficulty fully bending or straightening the affected joint
Not everyone with cartilage damage needs surgical restoration, however. The best candidates are typically younger, active people, usually under 50, who have damage confined to a specific area rather than widespread arthritis. These focused defects — often described as potholes in otherwise healthy cartilage — respond well to restoration techniques when conservative treatments like physical therapy and nonsteroidal anti-inflammatory medications fail to provide relief.
What is the Osteochondral Autograft Transfer System (OATS)?
The OATS procedure works like transplanting healthy grass plugs to repair a damaged lawn. During this surgery, doctors remove small cylinders of healthy cartilage along with the underlying bone from less-used areas of the joint, typically the edges of the joint, and press them into precisely measured holes at the damaged site.
This plug-and-play approach provides immediate filling of the defect with your own living tissue, which significantly improves healing and integration. OATS offers excellent long-term durability for small to medium-sized defects, with many patients returning to sports and active lifestyles after recovery.
However, this technique works best for younger patients whose cartilage remains healthy and resilient, and is most commonly performed in the knee joint, where donor sites are more accessible. The main limitation is the finite amount of healthy cartilage available for harvest. Surgeons can only take so many plugs of cartilage without creating new problems at the donor sites.
What is Microfracture Surgery?
Microfracture surgery taps into your body's natural healing process by creating small, strategic injuries to stimulate repair. During this procedure, surgeons clean the damaged cartilage area and then use specialized tools to drill tiny holes, known as microfractures, through the surface of the underlying bone. These holes allow bone marrow, which is rich with stem cells and growth factors, to seep into the damaged area and form a blood clot that gradually transforms into new cartilage tissue.
As one of the most commonly performed cartilage restoration techniques, microfracture offers several advantages:
It's minimally invasive by only requiring small incisions
It can be performed arthroscopically
It’s often the first treatment surgeons recommend for smaller defects
However, the new tissue that forms, called fibrocartilage, differs from your original hyaline cartilage. It's more like scar tissue with less durability and shock-absorbing ability. Research shows that while many patients experience good short-term pain relief and functional improvement, the results tend to deteriorate after two to five years, particularly in larger defects or in highly active individuals who place significant demands on their joints.
What is Allograft Cartilage Transplantation and Who Qualifies?
Allograft cartilage transplantation uses donor tissue, typically from deceased organ donors, to repair damaged joints when a patient's own cartilage isn't sufficient for self-repair.
During this procedure, surgeons precisely size and shape pieces of donated cartilage with its attached bone to fill large or irregularly shaped defects, much like fitting a custom puzzle piece. This technique becomes particularly valuable when dealing with extensive damage or in cases where earlier treatments like microfracture or OATS have failed to provide lasting relief.
Ideal candidates include younger, active patients with substantial isolated cartilage damage but otherwise healthy joints and good bone quality. While allograft transplantation can address larger problems than other techniques, it comes with distinct challenges:
Recovery typically takes six months to a year before full activity can resume
The body must accept tissue from another person, creating a small risk of immune reaction or infection despite careful donor screening
Additionally, the transplanted tissue may not integrate as completely as your own cartilage, potentially leading to graft deterioration over time, especially in high-demand joints like the knees.
What's the Recovery Like After Cartilage Restoration?
Recovery after cartilage restoration requires patience and commitment, as the newly repaired tissue needs time to mature and become stronger. Immediately following surgery, patients typically use crutches or wear specialized braces to protect the repair site. Most surgical procedures require a period of limited or non-weight-bearing, which ranges from two to eight weeks, depending on the technique and location.
Physical therapy becomes a cornerstone of recovery, beginning with gentle range-of-motion exercises and progressing to strength training and eventually sport-specific movements.
The timeline varies significantly by procedure. Microfracture patients may return to low-impact activities within three to four months, while OATS and allograft recipients typically need six months to a year before resuming running, jumping, or pivoting sports.
Patients who fully complete their prescribed rehabilitation protocols achieve better long-term function and satisfaction.
How Do You Choose the Right Cartilage Restoration Option?
Selecting the best cartilage restoration treatment option for you is similar to choosing the right tool for a specific home repair. The decision depends on the problems and your long-term goals. Defect size and location significantly influence the choice, as smaller, isolated damage often responds well to microfracture or OATS procedures, while more extensive or oddly shaped lesions typically require allograft transplantation to achieve complete coverage and a proper joint contour.
Your age and lifestyle also play a role in this decision. Younger patients with active lifestyles gain the most benefit from restoration procedures, while older adults with widespread arthritis may find better relief through partial or total joint replacement. The complexity of these factors underscores why consultation with an orthopedic surgeon specializing in cartilage restoration is important.
