What's the current wisdom on how to best look after your knee? A number of years ago I remember reading some studies where walking (low impact) was the only positively beneficial activity and that cycling was neither good nor bad provided your bike setup and technique was A1.
I more specialise in knees once they're caput. The degeneration once an injury occurs is complex and multifaceted, I've never seen any evidence to show the declined can be attenuated, the rate of decline maybe, but there is such a large element of individuality and luck involved.
The best acitivity is the one you enjoy doing that doesn't cause aggravation, fluffy answer, otherwise you and 99.99% of people don't stick to it.
Strength training is paramount, but as physios have little knowledge in exercise prescription this generally doesn't occur, or at least in the past. Squats, unilateral leg press, lunges but never open chain exercises like knee extension. Using real weight, we have 70+ year olds pressing 200+kg with single legs... symptom free.
Proprioceptive training, unilateral balance tasks, single leg jumps (more high end rehab), that sort of thing.
Activity is the most important thing, cycling is great, hence why so many runners turn to cycling once every run tends cause aggravation. But spnning is essentially as it results in less sheering load.
The biggest issue is as you age, you do less acitivty, leg strength declines, symtpoms get worse, activity declines further, suddenly you have a range of comorbidities from a single bad knee. Now your well over weight, leg strength is shit and your booked in for a knee replacement.
