From twisting and turning to bending and moving, every step you take, your knees bear the weight of your entire body – and that’s a big responsibility.

Knees are one of the most commonly injured joints, and arguably, one of the most important joints in your body. As a complex structure, composed of bones, tendons, ligaments, and cartilage, there can be many sources of knee pain. If you are experiencing knee pain or instability, please contact our patient care team to discuss if Regenexx Cayman stem cell or platelet-rich plasma treatments are the right choice for you.


If you’re experiencing knee pain, lack of mobility, or would like to treat your knee alongside other joints, please contact us to tell us more about your condition and see if we can help you. At Regenexx Cayman, we are 100% focused on orthopedics. This means we can treat many knee injuries and conditions, including damage to cartilage, ligaments, tendons, muscles, or bones.
  • Osteoarthritis
  • ACL, PCL, MCL, LCL tears or sprains
  • Runner’s knee
  • Tendonitis
  • Patellofemoral syndrome
  • And more…

Regenexx-C can also be a non-surgical alternative for those who may be considering total knee replacement surgery (knee arthroplasty), meniscus surgery (meniscectomy), or ACL, PCL, MCL, LCL surgery.


Depending on the severity of your knee issue, and after receiving your imaging and medical history, a physician may recommend platelet-rich plasma or a stem cell treatment. Our physicians use both types of treatment for knee injuries and conditions:

Real Results

“Before I had the Regenexx treatment, I was constantly dealing with knee popping, and my knee would hurt when I went snowboarding. It would get more and more sore, and at the end of the day, it would be really swollen. Having that treatment fix that issue was a huge help.”

– Taylor Gold, Professional Snowboarder 2014 Olympian, Regenexx-C knee, ankle, and stem cell storage patient


Regenexx tracks the post-procedure outcomes of patients in an active registry. Here are some of the major findings from our Regenexx-C knee patient results:
  • 1 year post-treatment, patients reported a functional level of 64%.

  • 6 months post-treatment, patients reported that their pain levels decreased to an average of just 1.3 out of 10.

  • 1 year post-treatment, patients reported an overall improvement of 66%.


Can Regenexx Cayman treatment help my knee?

Using both PRP and stem cell treatments, Regenexx Cayman has treated hundreds of patients with knee issues. Before booking treatment, you will be required to have a phone review to confirm your candidacy for treatment. During your phone review, the physician will conduct a thorough review of your imaging, medical history, and treatment goals. You will then receive a candidacy rating of good, fair, or poor, so you have a clear understanding of your expected outcome from knee treatment.

After my Regenexx knee procedure, when can I be active again?

Most patients resume normal mobility and light resistance training within one week of treatment, returning to sport and full lateral movement after approximately 7-9 weeks. Patients also report a continued improvement in function and decrease in pain many months after their procedure. You will be given specific post-procedure instructions to follow based on your specific treatment.

Will I need physical therapy after my Regenexx knee stem cell procedure?

Yes, we usually recommend physical therapy after treatment. You will receive specific post-procedure instructions and rehab protocols for your knee. These will detail restricted and permitted activities, therapeutic exercises, rehab progression, and recommendations for physical therapy following stem cell injections for the first three months after treatment.

Do you have outcome data relating to my specific knee condition e.g. knee osteoarthritis?

We can provide joint-specific outcome data (i.e. all knee patients), but not condition-specific data. Regenexx maintains an active patient registry of all patients and publicly publishes the outcomes of those who have been treated by Regenexx-SD and PRP treatments. Regenexx Cayman also regularly compiles Regenexx-C data from the registry. Please contact us if you would like to know more.

Can I have both knees treated at the same time?

Yes; if your Regenexx Cayman physician recommends it, you can have both knees treated at the same time with platelet rich plasma or stem cell treatments.

Will I need crutches or a wheelchair after my Regenexx knee procedure?

During your initial consultation, the physician will determine whether you will need crutches or a wheelchair. If required, Regenexx Cayman will provide you with crutches (to take home) or a wheelchair (for use on island).
