Which factor has the greatest influence on how long it will take for new bone tissue to grow into the pores of a replacement joint prosthesis and graft to the device?
A. The client's age
B. The client's cardiac status
C. The length of time the joint has degenerated
D. The degree of tissue damage resulting from joint degeneration
A
Bone growth and the ability to revascularize an injured area are slower in older adults. The older the client, the longer bone grafting may take. For this reason, replacement with a noncemented joint is usually not done on clients over 75 years old. Although the degree of degeneration can be a factor, it is not nearly as important as the client's age.
