@JR 137 , to say the least I am skeptical of
@jobo 's link. I have read a lot about joint damage from credible sources (like the Mayo Clinic, etc...)and have never seen anything that infers cartilage can repair itself or grows. I am certainly no expert, more like a sub-novice in that area. What is your opinion on the idea? If it in fact can repair itself, how is it done? I 100% believe you can improve joint health through exercise by strengthening the muscles and improving flexibility. But when a bone is damaged by wear or cartilage is simply worn away, can it be fixed?
Cartilage on the back of the kneecap can repair itself, as
@jobo ’s article states. I’ve rehabbed a ton of chondromalacia injuries. It’s an overuse injury where the cartilage on the back of the kneecap wears down. Depending on many factors, it can range to irritating for a few weeks to needing surgical repair. I dealt with college athletes and currently high school athletes, so of course my experience with it won’t be all encompassing. Younger and fitter athletes will heal faster, that’s just the nature of things. I treated chondromalacia with some OTC anti-inflammatories and using pre-wrap to make a strap of sorts that lifts up the kneecap. The same thing as those patellar tendon knee straps. Heat, ice, anti-inflammatories, and the strap took care of most cases. The longer it went on, the doc may have prescribed some stronger meds.
Older people will have a tougher time with chondromalacia. Some will heal, others won’t. I’m assuming a bigger factor in healing this injury is the way the patella tracks. If it’s naturally too far medial or lateral, there’s greater stress that’ll play a role.
But that’s the kneecap. That’s not inside the knee joint where Jobo is having a ridiculous time comprehending the difference for some reason. Articular cartilage inside the knee joint (on the surface of the tibia and femur) and the meniscuses (meniscuii?) won’t heal. Very, very select parts of the meniscus have been known to heal, but they’re not typical places.
You can absolutely relieve pain caused by the articular cartilage and/or meniscus through strengthening and the like, it’s not fixing the actual damage; it’s taking stress off of the damage. It’s like taking ibuprofen for a fever caused by infection - it’ll bring the fever down, but it won’t kill the bacteria/virus causing the fever. If the damage to the knee isn’t severe, strengthening it could be all you ever need. If it’s severe, not amount of strengthening nor anything else will help. Often enough slight damage will get worse as time goes by; standing, walking, running, etc. all cause damage. As the years add up, sometimes the damage gets more and more until it’s unbearable and needs to be fixed surgically.
Edit: But also if the damage is in the right place, or better yet wrong place, no amount of rehab is going to help. Certain meniscus tears will cause issues regardless of how strong the knee is, for example.
