Rebuilding & Regrowing Knee Cartilage

Rebuilding & Regrowing Knee Cartilage


by Chris Pallia MD

As a specialist in sports medicine, I wanted to educate you about a new product and/or concept that is available now for the repair of focal cartilage defects of the knee and other joints.

When someone sustains a traumatic injury to the knee with ongoing pain or mechanical
symptoms an MRI is recommended. If there is a focal full thickness cartilage defect and patients have developed pain from some overload due to the loss of cartilage, you may be a candidate for this innovative new procedure. Furthermore, patients who have an area of osteonecrosis in their knee that hasn’t healed may also be a candidate for this procedure.

There’s a new technique that rebuilds the cartilage and regrows the cartilage. We’ve heard many times that cartilage doesn’t regrow, but scientists now have developed a way to regrow cartilage in a lab and then re-implant it into the defect in the knee after amplifying the number of cells. The cells are inserted into a collagen membrane that gets placed into the focal cartilage defects such as what you see on this model.

This model shows a couple of representative cartilage defects that are very commonly encountered in younger athletic patients. And so, when there’s an area of cartilage loss here and you don’t repair it, all the cartilage on the edges of the lesion are going to slowly wear down and you’re going to get a progressive arthritic knee.

With this new technique, it helps prevent progression of arthritis, reduces pain from cartilage defects, and is a significant advancement in orthopedic technology.

I’ve been performing this procedure now for the last year and I’ve had excellent results. Making more people aware of this new technology will reduce pain and premature development of arthritis. If you’re interested or think you might have a focal cartilage lesion that needs treatment, I’d be happy to evaluate you at my office in Coronado or Sorrento Valley.

Dear Patients:

As most of you are aware, over the last several days and weeks we have been learning about the coronavirus (COVID-19) and how it is impacting our world.  At Synergy Orthopedic Specialists, we have one goal that we strive for, and that is to keep you, our patients, and our employees safe.  This has been the topic of our planning and conversations and we have implemented several measures to ensure that we do everything possible to reduce the threat of this disease.

Our offices are regularly cleaned and sanitized, but we are now ramping up those procedures to include wiping down counters and other surfaces more frequently.  Additionally, we have hand sanitizer available, and washrooms for thorough hand washing.  We are closely following the Centers for Disease Control’s (CDC) guidelines and recommendations to help prevent the spread of the virus.

Our employees have been instructed to frequently use antiseptic hand cleaner as well as handwashing per the CDC instructions.  We also encourage our patients to do the same. If our employees feel sick or begin running a temperature, they have been instructed to stay home.  Similarly, we request that patients who are not feeling well, reschedule their appointments and not come to our clinics while they are ill. 

If our employees become ill, our offices may be functioning with less that optimal staffing; therefore, we request your patience if there are longer than average wait times or other delays.  Any location that may have any direct exposure, will be quarantined for cleaning.

We will continue to closely monitor the situation and do all that we can to protect you and our employees.  For more information and guidelines on the Covid-19, please visit:

Thank you
