Hi, Poz222, I remember you, too, and am sorry to hear about your patella...disintegration (?). I had no real pain from the crack -- just a sensation that something wasn't right, and, of course, the loud crack when it happened. My neighbor was standing three feet away, and he heard it loud and clear, too. You're still very new in the patella recovery, and your knee is also young. Since my patella issue, I'm noticing more around the site. I think it's a hazard of the surgery they don't really discuss. At least they're prepared to handle it when it comes up.
I wore the brace to keep the patella from cracking further and requiring surgery. I was surprised at how comfortable the brace was, but after two and a half months, I'm tired of it. I took it off shortly after I got home on Monday, put it back on before bed Monday night. Took it off mid-morning on Tuesday and have left it off since then except for when I took a walk around the block this morning. My OS kept talking about quad weakness, but I haven't noticed any. The knee mostly bends, but at the maximum range of flex, it's a little stiff and sore. I believe walking will help that. He also said I could sit and hug the knee to me to get that stretch in. He made it look much easier than it is, but he's probably a hundred pounds lighter than me and a lot more trim. I do think I'll put the brace on and unlocked whenever I'm doing any significant walking around for the next week or so. I feel better with the extra support.
I'm not noticing any pain on top of the knee. Mine is on the lateral side, and I have a larger bump there than on the left lateral side. I meant to ask him about it on Monday, but I forgot. If I think of it, I'll ask at the next appointment -- unless it gets smaller or goes away over the next few weeks. The new right knee is only 9 months old, so it's still doing some healing from the TKR.
