Acl injury

Hi everyone, I had an acl surgery 10-11 years ago. In April I missed a step and I couldn’t move my leg properly. Then I reinjured myself and since then, I have had intermittent locking mainly whenever I squat or bend my knee for too long. I have got physio arranged soon other than that I haven’t had any pain and it doesn’t happen all the time.

I’m terrified I’m going to have to have another surgery, the previous surgery left me in a pretty bad state, well the recovery I mean. Im also terrified of that it means my knee is dying or something. I’ve read some horror stories.

As you can tell I’m a hypochondriac (lol) anyone else has had this? If so are you okay now?

Thank you
