Re: Knee pain please help! Locking up
Locking, catching, and giving way can all be signs of cartilage delamination. Make sure that your surgeon looks at the films (not just the report), and be sure to ask him if there is delamination. It can be detected on MRIs, but is usually not caught. And, it can be repaired arthroscopically once detected.
If you are unsure of what your doctor is doing during the surgery, you need to go back and make him explain himself! I have had hip surgery with an incompetent surgeon who did not have a plan. Make sure that your doctor has a plan and can articulate it to you.
If you know what the doc is doing, like ACL repair, then please post the procedure, and I am sure that other posters will share their surgical recovery stories and tips.
