Stem Cell Vs Knee Replacement, Which Is Better?

  • December 31, 2022

Knee injuries affect nearly 16% of the world’s population. Age, an inflammatory condition, or an injury could be to blame. For decades, the only treatment for severe knee damage was a surgical knee replacement. However, stem cell treatment is a new treatment for damaged knees that has recently been discovered by researchers. At this time, the only treatment that can regenerate and repair damaged knee cartilage is stem cell therapy. Your doctor is the right person to call for a response to this question. Stem cell treatment might be the most suitable option in some situations, especially if the patient has certain health conditions that prevent them from having surgery.



  • Stem cells are immature cells that can differentiate into any tissue and can be found in various parts of our bodies.
  • They can be found, among other places, in our blood, fatty tissues, and bone marrow. Various stem cells assist in the treatment of various health conditions.
  • The use of stem cells as a treatment is relatively new in the medical field. It is still in clinical trials, which have produced encouraging outcomes. However, the FDA must still approve this treatment.
  • Knee damage is usually caused by excessive wear and tear or an inflammatory condition. A knee injury can sometimes result from an accident.
  • Stem cells possess a number of unique properties that can assist in the healing of your injured knee. These properties can assist in the formation of stem cells to replace damaged ones that cannot be repaired.

Did you know that stem cell therapy is almost always successful?

Yes, in clinical studies, 80% of treated patients reported reduced pain and increased mobility. All of this without requiring surgery.


An out-of-the-box surgical procedure, knee replacement or knee arthroplasty replaces your entire knee joint. It has been the standard treatment for severe arthritis and knee damage for decades.

The damaged knee joint is replaced with a prosthesis during knee replacement surgery. Considered a last resort for individuals suffering from extreme pain and mobility issues.

So why would one need a Knee Replacement?

  • You have to understand that the cartilage in our knees acts as a shock absorber when we walk around. Simple activities like walking can cause severe pain when this cartilage is damaged, whether from an inflammatory condition, excessive wear and tear, or an accident.
  • A knee replacement procedure is necessary at this point. Most of the time, surgery is done under general anesthesia. Typically, the new prosthetic is made of metal, plastic, or both.
  • After surgery, patients are discharged from the hospital within three to five days, but recovery can take anywhere from six weeks to three months. Except for physical therapy, one’s movements are restricted during this time.
  • In 90% of cases, knee replacement lasts nearly fifteen years if the instructions are followed. However, in some instances, scar tissue develops at the surgical site, resulting in no pain relief for the patient.
  • Currently, knee replacement surgeries are routine medical procedures due to their high success rate. However, given that they are, in the end, a type of surgery, they do come with some risks that are common to all surgeries.
  • Blood clots in the legs or lungs and nerve damage are the most common dangers. However, these dangers only affect a small percentage of people.

Knee Replacement vs Stem Cell Therapy

Uses the body’s own cells Uses an artificial metal or plastic prosthesis
Reduces rheumatoid arthritis’s long-term pain by releasing anti-inflammatory factors As long as inflammation is still present, pain may return.
Nerve damage at the injection site is one of the side effects. Nerve damage and blood clots are among the side effects.

Is Stem Cell Therapy a Better Option Than Knee Replacement Surgery?

  • This question has no clear answer. When the patient has an auto-immune or inflammatory condition, for example, stem cell therapy is clearly the better option.
  • In other instances, a decision cannot be made at this time. A knee replacement might be the preferred option at this point in very severe cases of damage. In such circumstances, the effectiveness of stem cell therapy is still being evaluated.
  • Regardless, one thing is for sure. The most promising new treatment in the last two decades has been stem cell therapy. Additionally, it has the potential to soon completely replace surgical knee replacement.
