There are different types of prostheses, with different features, and you can discuss the options with your doctor. A hip replacement can be performed using either a cement or non-cement type of glue. A cemented prosthesis allows the patient to return to full weight-bearing activities sooner than a non-cemented one. With a non-cemented hip prosthesis, it may be 3 months or longer before the patient can put all of her weight on the affected limb. However, a non-cemented prosthesis is ultimately stronger, and may be easier to deal with than a cemented prosthesis if additional surgery is ever required. In general, an older, less active patient who will probably not wear through it is offered a cemented hip prosthesis, while a younger, more active patient is typically offered the non-cemented one. Cemented prostheses are typically used in knee replacements.
