Total Hip Replacement without Bone Cement is Still Durable after 20 years.
After total hip replacement was initially done for several years a new program started in which the prosthesis was coated with a scratchy sandpaper type surface. It was inserted into the bone in that way for both the socket and the stem that goes into the femur. These are so called porous coated implants. Bone grows into the implant and holds it and therefore bypasses the need for bone cement, which was used in the early years.
This has proven to be very effective fixation because 95% of these implants are still functioning well after 20 years.
Earlier generation implants relying on the use of bone cement to secure the implant have been associated with a higher rate of failure.
I have used porous coated implants in my practice for many years and have found them to be highly effective and long lasting.
