What is cementless TKA?
Cementless knee implants, also known as press-fit knee implants, have a rough, porous surface that encourages new bone growth. The new bone grows into the spaces in the implant, holding it in place without the need for cement.
What is UKA vs TKA?
Unicompartmental knee arthroplasty (UKA; also known as partial knee replacement) and total knee arthroplasty (TKA) are treatment options for patients whose osteoarthritis involves only one of the three knee compartments; however, most patients with this condition undergo TKA.
What is a cemented TKA?
A cemented joint prosthesis uses fast-drying bone cement to help affix it to the bone. A cementless joint prosthesis, sometimes called a press-fit prosthesis, is specially textured to allow the bone to grow onto it and adhere to it over time.
What is mobile bearing TKA?
The mobile bearing (MB) concept in total knee arthroplasty (TKA) was developed as an alternative to fixed bearing (FB) implants in order to reduce wear and improve range of motion (ROM), especially focused on younger patients.
How long do knee implants last?
In 85% to 90% of people who have a total knee replacement, the knee implants used will last about 15 to 20 years. This means that some patients who have a knee replacement at a younger age may eventually need a second operation to clean the bone surfaces and refixate the implants.
What does Unicondylar mean?
Introduction. Unicondylar Knee Replacement simply means that only a part of the knee joint is replaced through a smaller incision than would normally be used for a total knee replacement.
Is cement used in hip replacement?
A cemented hip replacement uses a polymethylmethacrylate (PMMA) bone cement to fix the implant surface to the bone. The bone cement creates a grout and fixes the implant by acting as an interlocking surface between the implant and the bone rather than simply gluing the implant to the bone.
Is cement used in knee replacement?
A cemented knee replacement requires the use of fast-drying cement for the prosthetic components to adhere to the natural bone. Since this kind of cement dries quickly, the surgeon can be confident that the prosthetic was properly implanted.
What is cruciate retaining knee replacement?
Bi-cruciate-retaining (BCR) total knee arthroplasty (TKA), which retains both the anterior (ACL) and posterior cruciate (PCL) ligaments, serves as an alternative to the traditional TKA procedure.
What is a fixed bearing knee?
A fixed-bearing knee design has round femoral components that articulate with a relatively flat tibial articular surface. Although this configuration allows for some axial rotation, it results in high contact stress between the femoral and tibial surface.
