Hello, @grahamg77, welcome to Connect. As a group, we are committed to sharing our experiences so that we get feedback and suggestions from other members. I understand the pain in the front of the knee. You may be more than correct about overuse being the cause of your pain and discomfort.

You are very active and that is great. I have a question and then a memory to share with you. Do you participate in a Yoga class or do a set of Yoga exercises every day. You may want to look at "Legs up the Wall" and see if that helps at all.

And now for the memory. It is the response from my surgeon when I asked him how long my TKR would last. At the time I was a "trekker" traveling to beautiful places with a group of ladies and walking, walking, walking. We did the Ring of Kerry in Ireland.....the back hills of Vermont......Sechelt island, and 14 miles of sandy beach near Monterrey. Our practice was at least 3 miles a day and usually 5 or 6 around the hill village I lived in at 6000 feet.

Here was his answer, "Chris, your new knee will last a lifetime if all you do is walk uphill. It will only last about five years if you choose to walk downhill." That's all he had to say.....I got it. When I see that you do 10 to 15 flights of stairs daily......I assume that is up and down. If so, you may not realize how much pressure you are putting on that knee when you take a step down, especially when leading with the TKR foot.

And now for your bonus........when I had done a bit too much and was beginning to experience pain, I was introduced to an MFR therapist and the rest is history. It took six weeks or more to rid my knee of the pain. It never has happened again. And to make sure I keep that knee healthy......I also had to have the other one done last year. It is doing extremely well. I no longer live at 6000 feet because I live in MN. No hills to climb or come down.

(a helpful PS.........you may even have built up some scar tissue that can be removed with MFR.

May you be free, protected, and safe from inner and outer harm.
Chris

Please let me know if this sounds like it is worth a try.
