RockyBones, yes I was active before my bilateral TKR.
I ran/walked marathons, half marathons, and even an annual 100 mile race with bone on bone arthritis in my knees for 7 years before I finally had my surgery. (That SOUNDS worse than it really was - I got rooster shots to lubricate my knee joints twice a year, and I had a pair of bulky unloader knee braces that I ran every race with). Plus, I ran a slow run. I never worried about winning the race - only successfully completing the race.
But it wasn’t so much the fact that I was physically active that helped me so much.
It was the fact that I was in the habit of exercising long and hard. Exercise is a way of life to me, and so I did it often no matter what. A physical therapist friend had warned me in advance that the harder (within reason, of course) I worked in the first days and weeks after surgery, the easier and less painful things would be one month, or two months or three months after surgery.
So I always made sure to go the extra mile with my exercise. Even as early as my first hours out of the recovery room, when I did frequent ankle pumps and butt squeezes.
But there were other things, too.
I had THE BEST SURGEON (according to the official ranking of orthopedic surgeons who do knee replacements, which you can find on medicare.gov) in my state (Tennessee).
My doctor’s exceptional surgery history was due in great part to his skill as a surgeon, of course. But it is also because of the all the “extras” that he gives every patient. For example, he mandates that every patient sleep six hours a night in a leg immobilizer for the first two or three weeks after surgery. Now, I hated sleeping in the thing, but sleeping in the leg immobilizer all but completely insures that the patient will have 100% extension down the road, because of how it stretches the joint while sleeping and also, how it helps prevent the formation of dehabilitating scar tissue.
The PT protocol he mandates PTs use for his patients is somewhat different than standard fare PT, and the differences really help with that flexion.
He mandates that every patient on Medicare (the insurance provider for most of his patients) be given one of those knee cooling ice machines at Medicare’s expense, which also helps his patients to do more exercise in the early weeks (because they get fast pain relief after PT from the ice machine). That, too, helps with developing flexion.
But that was me.
RockyBones, the first thing to realize is that we all recover from this surgery at a different pace.
Your flexion might not be the same as what mine was at 2 months, but you are actually doing quite well.
Keep working the exercises your PT gives you. Unless you have some scar tissue that has developed inside the knee, the knee bending exercises will get you where you need to go.
(If you do have problematic scar tissue formation inside the knee, your surgeon will probably do a Manipulation under Anastesia, whivh will break up the scar tissue and get you back on track).
Keep working that knee, RockyBones. Do not be afraid of the momentary pain when you work it, because each time you work the knee, the pain will decrease.
Ultimately, the way to get pain free knees with good flexion is to exercise the knee frequently, and as far into the bend position as you can.
Yes, there will be some pain. For a while, anyway.
But the more you work the knee, the less it will hurt.
Until one day, it will bend with ease, and will not hurt at all.
You WILL get there, RockyBones!
