If you have had a total knee replacement you may feel like your knee is weird or heavy afterwards. Your body can sense the weight difference between a normal knee and a replacement, especially in the time following a knee replacement surgery. With proper rehabilitation and strengthening of surrounding muscles this feeling can dissipate over time. It is pretty normal for people to feel like their knee is a little bit unnatural and this is because you have replaced your natural with an artificial implant and the implants are on average 0.6 pounds heavier than the knee that they replaced and so this is why your knee often feels heavier afterwards. Although this is not a huge difference, it highlights the importance of proper strengthening in your rehab afterwards.
