Hey - not necessarily. Essentially once it has set in, the cartilage undergoes changes that mean it doesn’t repair as well and is also more susceptible to damage.
Activities that weren’t a problem before may be quite detrimental now (eg board climbing).
I think the most up to date thinking for the root cause ranges from a hereditary defect in your type ii collagen, to things that cause an imbalance in the biochemistry of the joint. It’s proposed there are multiple different causes and they might need different treatment approaches.
Overuse and high impact compressive forces are contributing factors - but very few people get OA as a result of those.
In the past I did thai boxing, olympic weightlifting and a few periods of intense manual work. I suspect all of those played a bigger role than climbing. I also imagine 99 out of 100 people could do the same and not have any problems.
My dad also had knee problems from his 40s - which they thought was caused by poor alignment (bow legged). With my elbows too I think an increased hereditary risk is a possibility.
And from the MRIs it could have started 5 or even 10 years ago. Its just been noticeable the last two, and with hindsight probably longer (dull ache/soreness in forearms - not an alarming sensation for a climber!)
