Hi Janie,

Just my opinion, but if your left knee is painful enough to affect your gait, and that's almost always the case, then something else usually starts to hurt. I think you may be right - your left knee is bothering you enough that it's affecting your gait and that's affecting your good knee.

I used to be a marathoner. I had numerous injuries, most of them in my legs. If I tweaked a knee and kept running, a problem would appear, like a groin pull - all caused by a slight way I changed my running style to accommodate a painful knee. I wasn't aware of it, and that's what makes it puzzling.

You also mentioned pain when you uncrossed your legs after sitting. I'm no Dr, but crossing your legs can put pressure on the knee you move to cross your legs. So I would avoid that.

But if the prosthesis looks good, I'm betting the left knee TKR will resolve most of these problems. I had both knees replaced this year, about 4 months apart. Before I went in to get the second knee replaced, I had a noticeable limp, caused by bone on bone in my bad knee. If I waited longer, I'm sure I would have had the problem you described.

FWIW, both of my knees were replaced by a surgeon using the Mako robotic assistant. I have nothing but good things to say about it. I got in shape ahead of surgery and hit the PT aggressively immediately after surgery.

All the best to you Janie!

Joe
