cartilage
« on: October 14, 2020, 08:57:18 PM »
I'm someone who has recently been suffering from some knee pain.
However, my problems are just in the femoral-tibial joint (and not in my kneecap).

I'm aware I can't be too obsessed about this, but I would like to be as well as informed as possible.
And as so, I have three questions (for now).

1) Does climbing stairs wear down even more the cartilage in the femoral-tibial joint?

2) And does walking on one's toes poses more pressure on the kneecap?

3) My last question is about a more controversial issue.
The more traditional position about cartilage is that once it has been damaged (or injured), it won't regenerate.
However, there are a few doctors and researchers who do claim that cartilage can regenerate itself.
Among other claims, I've heard that some nutrients can rebuild cartilage, such glucosamine, chondroitin sulphate, MSM and curcumin (to state the main ones).
But does this refer both to cartilage in the kneecap and in the femoral-tibia joint?

Note: Maybe these questions sound weird (specially in regard to the last question), but I've been doing some research on this, and almost all the information I got only refered to the kneecap (so I wonder if it's easier to heal the cartilage in the kneecap than in the femoral-tibial cartilage.)

Thank you for your attention

1. I think it is more the patello-femoral joint that experiences higher loading during stair-climbing.
2. I believe so.
3. Healing is generally with fibrocartilage rather than cartilage (eg after microfracture etc), but I understand that there is real healing with joint distraction.
