Another runner during my late 20s to late 30s given up due to Osteoarthritis in my knees and dealing with it in my 70s. Two things have helped, the big one for cycling is steroid shots in the knee which are working great until a replacement is needed as the number of shots is limited over time. Second which has helped with OA in hands, wrists, hips, etc. as well as knees is Microlactin a milk protein concentrate.

I have significant arthritis, but not the knees. They get sore only if I am riding hard with some mashing of the pedals. My spine and shoulders are quite bothersome. My hands, particularly the thumbs, can sometimes really hurt from riding. A relaxed position with ease of motion to various hand positions is critical for my comfort. At 73, I an ok with that.

I ride to forestall arthritis. Now closer to 77 than 76 I've worked part-time in a hardware store since late in 2014, often exceed 14,000 steps in a nine-hour day on a concrete floor. 50# bags of birdseed or concrete mix, 40# boxes of nuts & bolts stacked & stocked on a routine basis.

Riding uses other muscles and movements that help my body stay flexible I think; what I see around me in others around my age gives me pause for what their earlier life activities & diets have left them with. I'm quite glad I can still ride miles when weather suits, on a trainer when it doesn't. My cardiologist agrees with this.

Only major complaint now is left thumb arthritis, likely from repeated hyperextension injury over time a few years back when I was messing with tools and got caught by surprise when that thumb joint 'popped' unexpectedly.

I am 31y old. I diagnosed with CMP grade 1 both leg. Left leg have ITB and hip pain, and my VMO weaker in my left leg. I found a very good sport orthopedic doctor who saw my MRI's both of my knees, and he said my patella sitting higher than normal, and that can cause a tracking problem and can cause cartilage damage.
6 months of PT strengthening and stretching exercises +medicine like MSM+glucosamine+collagen not giving a good improvement.
My doctor want a correction surgery, and want to fix the abnormal movement of the patella. Also can smoothening the damaged cartilage. After the recovery i can sport again, but need to continue the VMO+ gluteus strengthening exercises to saving my knees.
This is my last hope, and want to fix it, because I love cycling so much!

Remember Marv Levy? He was the head coach of the Buffalo Bills during their four Superbowl runs during the 1990's. I recall reading an article about him that laid out his workout routine. At 73 he was running many miles per week despite arthritic knees. He claimed that the running helped address his symptoms, keeping everything at bay. In my personal case, I only have aches and pains when I'm not working out with regularity and with some serious effort. My knees and back hurt when on not putting in hard bikes, runs, swims and weight lifting. Bone-on-bone is a different thing and YMMV depending upon the state of your OA and degeneration. But I find that hard biking is not only impact free - except when you wipe out - but that it really greases up the joints and serves to make me feel great. Give it a shot an see how it feels.

In my case the pain, and function problems is a two different thing. My knee 99% the left, not have great tracking movmeen. If I have this weird feeling, and i continue pushing the pedals, then I felt my knee want to pop back to the normal position, and this irritating my knee. Tight ITB, and tight tendons.I want to fix my patella abnormal movement, and smoothening the cartilage, because mine have cartilage fibrillation. After the recover i can go back to sport. I spent a lot of money for the doctor's, and PT, and i can't fix it without surgery. So sometimes the surgery the last option which can help to you. Everyone is different, but mine a bit complicated.

Robby, there's nothing for it but to keep moving. I also encourage a significant stretching routine AFTER you've worked out. Do it when you body is hot. Get on the floor and get into weird stretch positions. For my shoulder OA (I also have torn AC joints), I drink lots of broth. I think the collagen in natural broth - particularly beef broth - has helped quite a bit.

Argoman thank you for your reply!I stretching daily before ride, and foamrolling after with stretching. And did almost daily strengthening exercises too, so I doing everything what I can. I will inform you about my situation later.

There are three 3-letter acronyms in your first sentence, and I don't recognize any of them. WTF?

Hello!

CMP = Chondromalacia Patella / damaged cartilage
ITB = Iliotibial band
VMO = Vastus Medialis Oblique / muscles

I hope you are happy now...

Thanks!

Find an experienced bicycle rider to get you going at first and then go for it.

Your transition from running to cycling will be seamless with a truly appreciated recovery time afterwards...

well you should be fine if you live to 108 then
