Every knee replacement implant's plastic spacer begins to wear down with normal use and movement. Excessive exercise or weight gain can hasten the regular wear of a knee replacement, causing it to loosen and become painful. As a result, a knee replacement surgeon will recommend that you avoid high-impact activities like running, jogging, leaping, and other high-impact sports for the rest of your life after surgery. Knee replacements can survive for many years if the activity is modified appropriately.
