Factors such as the quality of the surgical technique used and the type and fit of the knee implant can also contribute to a knee replacement loosening. If the knee replacement is not properly aligned or positioned during surgery, it could lead to uneven wear and ultimately cause the implant to loosen. The Patient's Weight and Activity Level
