Get Wear Of Mobile Bearing Knees: Is It Necessarily Less? - Unmc - Unmc

Knee joint replacement is a surgery to replace a knee joint with a man-made artificial joint. The artificial joint is called a prosthesis.

The posterior-stabilized designs utilize a tibial post and femoral cam to substitute for the PCL, which allows femoral rollback and attempts to prevent anterior movement of the femur.

There are no clinically relevant differences between CR and PS TKA in terms of clinical, functional, radiological outcome, and complications, while PS TKA is superior to CR TKA in respects of ROM, while whether this superiority matters or not in clinical practice still needs further investigation and longer follow-up.

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.

Minimally-invasive quadriceps-sparing total knee replacement is a new procedure....The main potential benefits of this new technique include: More rapid return of knee function. ... Smaller incision. ... Decreased post-operative pain. ... Same reliable surgical implants as Traditional Knee Replacement.

In a cruciate retaining (CR) TKA, the posterior cruciate ligament (PCL) is preserved to promote stability and femoral rollback [2]. In a posterior stabilized (PS) design, however, the PCL is sacrificed and replaced by a post/cam mechanism to influence knee stability [2] .

If they ask me specifically about what knee implant is the best for knee replacement surgery, then my recommendation for nearly all patients is a Conformis custom-made knee. These precisely match the size, shape and contours of your own knee joint.

With a "mobile bearing" prosthesis, the polyethylene insert can rotate short distances within the metal tibial component. This implant has a rotation that allows a more natural and wider range of knee motion and gives overall better knee function.
