Christopher Ellis explains tendinitis as acute inflammation versus tendinosis as chronic fraying of tendon fibers. Collagen loss happens at about 1% per year, resulting in 40% less by age 40. Mechanical overload, aging, and collagen deficiency are the main culprits behind tendon problems.
A tendinosis is more of a chronic condition. That's where you get fraying or disorganization of the fibers of the tendon. So tendinitis, acute. Tendinosis, chronic. The difference there is your approach in rehabbing. It can be slightly different. Now, what causes this? So classically it's described as overload. There's some other things too, such as aging. There's, you know, lack of collagen. The diet can do it. In fact, you lose about 1% of collagen per year. So by the time you're 40, You've lost about 40% of your collagen.
