it has been reported on this Forum that the clunking without pain is normal. However, the thought of a life of clunking is not one that I look forward to!
Don't assume that, just because your knee is clunking now, it will continue to do so for ever.
My right knee clicked and clunked for about 4 years, but the clunking gradually grew less noticeable, until one day I realised it had stopped.
Many people find that the clunking goes away long before mine did.
My knee is fine, 7 years old now, and I'm hardly aware of it because it functions so well
I have joined a local Gym and am engaging in exercises to target my quads, hamstrings and to increase my range of movement. Only two days into to this (in combination with my weekly Physiotherapy) so I am hoping to see some improvement.
I think you're rushing your knee. It's only a couple of weeks past 2 months old. Complete recovery takes a full year.
It may be too soon for doing strengthening exercises at the gym, and that could be the cause of your new pain.
I'm going to ask
@Josephine to advise you, but I suggest you back off those gym exercises for at least another month. Allow your knee some more time to heal.
Working hard at exercises isn't necessary for a good recovery. IN fact, doing too much, too soon might slow down the recovery.
It's not exercising that gets you your ROM - it's time. Time to recover, time for swelling and pain to settle, and time to heal. Your ROM is there right from the start, just waiting for all that to happen, so it can show itself.
