Is “Ironman Knee” Blocking Your Bucket List?

POSTED ON IN Knee Knee Procedure Outcomes Latest News Regenexx-SD Sports Injury BY Chris Centeno

Everyone has a bucket list or the things they want to do before they exit stage left. When you’re in your 30s and 40s, most of us don’t think about it too much. When you hit your 50s you begin to think about maybe crossing a few thing off. So it was for a patient of Dr. Leiber’s – our Regenexx Network provider in the Tampa Bay area. She had always wanted to be an Ironman, but when she began to try to increase her activities, her 56 year old body wouldn’t cooperate as she found out the hard way about the phenomenon of Ironman Knee. This is defined by the sudden appearance of knee pain by athletes either training for, or after a big race. Thankfully, Dr. Leiber was able to use the Regenexx procedures to help her reach her goals.

This patient is a 56 year old athletic school teacher who began running and trying mini-triathlons at age 50. She promptly lost 20-30 lbs, but unfortunately, she had a prior meniscectomy knee surgery on both sides. When Dr. Leiber saw her for the first time last December, she was having intermittent 8-9/10 pain which caused difficulty with pretty much all athletic endeavors including biking, running, prolonged walking, boot camp, triathlon training, and climbing. At that point, becoming an IronMan was all but a distant dream. Knee replacement had been recommended to her after activity modification, NSAID drugs like Motrin and a steroid injection had failed.

Her imaging in the office showed moderate to severe joint space narrowing with areas of full thickness cartilage loss over the inside of the knee and groove for the knee cap. Her meniscus appeared severely degenerated on both sides and her main knee ligaments (ACL and PCL) were partially torn. Suffice it to say that her knee was a structural mess!

Since completing the Ironman was on her bucket list and doing that with a knee replacement was very unlikely, in February of this year she gave Regenexx a shot. Dr. Leiber completed the Regenexx-SD procedure and sent her to physical therapy to begin beefing up her muscles. Sure enough, she began training for the Ironman soon after and after not seeing her for awhile he received the following email from her:
“Please let Dr. Leiber know that I did it and I am an IRONMAN!!  (Also, my knee held up really well).”

He saw her this past week for a Regenexx-SCP maintenance procedure. For very active athletes and/or patients with severe arthritis, we offer the ability to get regenerative shots to “top up” the stem cell procedure. Her knee was doing great without any swelling with tighter ligaments and no pain.

The upshot? This is a great story of perseverance despite all odds. What we love to do at Regenexx is to use advanced interventional orthopedics to allow aging athletes to keep going. We all have that list of things that we envision for ourselves when we get older, and when the reality of what happens in the body begins to get out of whack with those goals, it’s time to consult a Regenexx doc!

    "The Iron Man" case was really heartening to read about as I am also a patient of Dr. Leiber's!


    Regenexx Team says

    Thanks Masuma! That's wonderful to hear!


    Heather Kennedy says

    This gives me some hope. I am (well, was) a marathon runner up until this past May when knee swelling brought me to ortho office with eventual diagnosis of grade 4 arthritis. I'm only 45!


    Regenexx Team says

    So glad the blog provided some encouragement! It would be a good idea to get that knee sorted as it's not only the knee but how it can negatively affect your biomechanics in general causing other problems. Here is some info on how knee arthritis can be treated without surgery: An exam by someone who can determine what set the stage for the arthritis to develop (lax ligaments, low back issue, tracking issue, etc) so once treated the problem doesn't recur is extremely important. If we can be of any assistance, let us know.

    I have heard this Stem Cell Therapy does not work if you have complex meniscus tear?
    Has any one done Regenexx for what have call COMPLEX MENISUC TEAR?
    I am going through this problem in both my knees, I am 60 and have unpredictable moderate pain in both knees. Sometime its burning pain, sometime its sharp and sudden pain. I have done RICE for 6 months mad Physical Therapy and it has helped but do I have chance to do Stem Cells Therapy without Arthroscopy?


    Regenexx Team says

    Yes you do! We treat complex meniscus tears regularly. The one thing to avoid is the arthroscopy as studies have shown that meniscus surgery, which usually involves removing sections of meniscus rather than repairing it, results in an unstable joint creating ongoing problems. An example of one of our Providers and a complex meniscus tear:
