Stem Cells and Joint Surgery: Why Treating the Whole Joint Matters
Welcome back! In our last blog, we explained why we use living stem cells instead of exosomes.
Earlier, in our blog on how stem cells heal, we promised to talk about arthritis and injured tendons and ligaments. Todaywe’ll do that by asking a very practical question: if you need joint surgery,where do stem cells fit in? Stem cellsare the basic repair cells present in the body.
Your Joint Is an Organ, Not Just a Hinge
Most of us picture a knee or shoulder as a hinge with a cushion of cartilage. But researchers now describe the joint as anorgan, like a team of tissues that work together:
• Cartilage - the smooth gliding surface
• Bone - the foundation underneath the cartilage
• Synovium -the joint lining that makes lubricating fluid
• Meniscus, ligaments, and tendons - the shock absorbers, stabilizers, and movers
• Surrounding muscle, nerves, bursa, and fat pads
A landmark review in Arthritis & Rheumatism made this case: osteoarthritis isn’t simply wear and tear, butabnormal remodeling of all the joint tissues, driven by inflammation inside thejoint. The authors called the end result “joint failure.” [1]
Here’s why that matters: when one part of thejoint is injured, the whole organ feels it.
Surgery Fixes the Structure. It Doesn’t AlwaysFix the Environment.
Surgeons are excellent at replacing a joint or repairing a torn ligament. But the injury also leaves behind an inflamed, stressed joint “organ,” and the data shows that environment matters:
• ACL tears: A 2023 review of studies with 10+ years offollow-up found post-traumatic arthritis in about 38% of patients treated withsurgery and about 41% treated without it. The authors concluded that theoriginal injury, however it’s managed, likely leads to arthritis within 20years.[2]
• Injury beyondone structure: A long-termreview found arthritis in 0–13% of patients after an isolated ACL tear, but21–48% when the meniscus was injured too.[3]
• Rotator cuff: Some studies report re-tear rates after repairranging from 40% to 94%.[4]
The takeaway: the more of the joint that is injured, the higher the long-term risk. Fixing one piece doesn’t automaticallyheal the rest.
What Happens When Stem Cells Join the Surgery?
This is where it gets exciting. Researchers have tested adding stem cells at the time of (or shortly after) surgery:
• Shoulder (rotator cuff): In a study of 90 patients, half received stem cells during their repair. At six months, everytreated repair had healed versus 67% of the surgery-only group. At ten years, 87% of treated repairs were still intact versus 44% without stem cells.[5]
• Shoulder,randomized trial: In a 2023 trial of 91 patients, re-tears on MRI at one year were 18% with stem cellsversus 57% with surgery alone.[6]
• Knee (meniscus): In a randomized, double-blind trial of 55 patients, a single stem cell injection wasgiven 7–10 days after a partial meniscus removal. At one year, 24% of the lower-dose group showed meaningful meniscus regrowth on MRI; none of thecontrol group did. Patients with arthritic changes also reported less pain.[7]
• Knee (realignment + cartilage): In arandomized trial of 56 patients having a realignment surgery plus a cartilageprocedure, those who also received stem cell injections had better clinicalscores and better cartilage repair on MRI at two years.[8]
The Paramedic Returns
Remember our stem cell paramedic (click here to read)? Stem cells produce a wide range of biomedicines that manage the healing process of damaged tissues. Think of the surgeon as the construction crewrebuilding a collapsed bridge. That’s essential work. But the neighborhood around the bridge is still hurting. The stem cells are the paramedics workingthe whole scene: Calming the inflammation, releasing growth factors, andcalling in repair crews to the tissues the surgeon didn’t touch. Surgeryrepairs the part. Stem cells help care for the whole organ.
Already Having Joint Surgery? Start Your StemCell Bank!
Here’s a twist. Even if stem cells aren’t needed for your joint surgery, the surgery itself is an opportunity. Stem cells can be found in very high concentration in fat tissue, so while you’re already in the operating room, a simple and easy fat collection can start your own PSC stem cell bank. Your own cells, banked and ready for the nextinjury, the next joint, or the next surgery. One trip to the operating room,and your paramedics are on call for years to come.
What This Means for You
If you’re facing joint surgery, especially if your injury goes beyond the cartilage to a ligament, tendon, or meniscus, it’s worth asking how the whole joint will be supported during healing,not just the part being repaired. And, if you’re having any joint surgery, askabout collecting fat to start your stem cell bank.

Common Questions
Once banked through our StemReady™ program, your stem cells are cryopreserved and securely stored, ready for use when you and your physician decide. While not all therapies are commercially available yet, you may qualify for programs like the FDA's compassionate use or the Federal Right-to-Try Act if you have a life-threatening or debilitating condition.
Ask our team how you may qualify.
The cost of our services at Personalized Stem Cells varies depending on the specific treatment plan and stem cell banking options you choose.
Here are the general starting points for PSC services:
- StemPreserve: $2,500, plus banking at $750 per year (first year included).
- StemReady: Starting at $18,750 for 5 vials, which includes preparation of cells for immediate use.
These are your initial costs and do not include any additional fees that your doctor may charge to perform the lipoaspiration or treatment. For a detailed breakdown and to discuss payment options, please contact our customer service team. We're committed to providing transparent and comprehensive pricing information.
Getting started with stem cell banking at PSC is easy. Simply schedule a consultation through our website or contact our team directly. We’ll guide you through the entire process, from the initial collection of your cells to their long-term storage, ensuring you have all the information you need to make an informed decision.

PSC’s cell therapies are currently being investigated through formal FDA clinical trials with leading scientists and institutions. PSC has completed its first safety and efficacy study and submitted the findings to the FDA. Until formal FDA approval is obtained, PSC cannot make specific claims about this therapy. However, our initial safety and efficacy study is available upon request and has been published in a peer-reviewed journal.
PSC adheres to stringent FDA guidelines to guarantee the safety and quality of your stored stem cells. Our state-of-the-art lab utilizes advanced processing techniques to ensure that your cells are preserved at the highest standards. Every batch of stem cells is tested for sterility and purity.
