The nurse is preparing a client for a hip replacement with the use of porous-coated cementless joint components. What does the nurse know is the benefit of this type of component?
A) The component is less expensive because there is no cement used.
B) The client will not reject the prosthesis because there is no cement on the prosthetics.
C) It prevents the client from developing infection related to the application of cement in the joint spaces.
D) It allows the bone to grow into the prosthesis and securely fix the joint replacement in place.
D
Feedback:
Porous-coated cementless joint components are used to allow the bone to grow into the prosthesis and thus securely fix the joint replacement in place. The prosthesis is not less expensive and cost is not a factor in reconstruction. The client may still have a local or systemic reaction to the prostheses even if it does not have cement.
