Hi QTPie: Unfortunately, it can take a long time for full recovery of knee replacement -- perhaps a year or more, even though you're usually mobile and walking long before then. Since you've had additional surgery (scar tissue removal and manipulation), there is some recovery from that as well. (I've had hip, knee and shoulder replacements so I have some experience.) It's very frustrating even though we know that everyone heals at a different rate! While I certainly can't give you medical advice, there are two things I'd suggest you consider. First have an honest discussion with your doctor and ask how long full recovery is. I've found that some doctors aren't up front with this information so our hopes and expectations are more optimistic than they should be. If your doctor is also concerned about your progress, then it certainly wouldn't hurt to get a second opinion. Joint replacement is a tough decision and a major surgery. I hope you find (as I have) that when you're fully recovered it makes an incredible positive difference in your life.
