Full recovery from a knee replacement takes 52 weeks (one year, on average) and you are 10 weeks. Recently I compared this recovery to baking cookies. My chocolate chip cookies take 12 minutes to completely bake. If I take them out earlier, at 2 minutes, 4, 8 or whatever, they will only be partially baked, and not all that tasty, because they’re not done yet. The same is true of our knee at 2 months, or 3 months, etc. It needs time to finish healing.
