Concrete Benefits Found With Cementless Hip Replacement

However, older patients can get in on the act as well. A second study suggests that even patients as old as 90 can benefit from cementless hip replacement, in contrast to earlier concerns about poor fixation, pain, and cost, say William J. Hozack, MD, and colleagues from the Rothman Institute at Thomas Jefferson University in Philadelphia.
For 11 years, they followed almost 150 patients 80-90 years old who underwent their first total hip replacement with the cementless devices. About 19% of patients had early medical complications from the surgery, but there were no deaths while the patients were in the hospital and no complications such as fractures, dislocations, infections, or large blood clots, the researchers say. The thigh and hip components of all implants appeared to be stable, and in 96% of patients there was evidence of bone ingrowth.
"Results equaled that of [the traditional cemented hip replacement]. With ever-increasing life expectancy and activity of the elderly, arbitrary age criteria for implant selection are inappropriate and cementless [hip replacement] is a reasonable choice," says Hozack, who is professor of orthopaedics at the Rothman Institute.
- Bone specialists report that most patients receiving artificial hip implants that were held in place without cement had good results for as long as 15 years after their surgery.
- An observer notes that he believes cementless hip replacements can last for the rest of the patient's life.
- Long-lasting cementless hip replacements would be particularly attractive to younger patients, who wouldn't need to replace the implant after about 15 years, as is common with cemented varieties today. Researchers report patients as old as 90 had good results with the cementless devices as well.
