Research has shown that it can lead to a more rapid return to functional activities after surgery. This entry was posted in Blog. Instead of cement, these devices have a special surface that encourages bone to grow into the implant for fixation. The polyethylene from the tibial component of the device is attached to a metal component underneath.
More than different knee replacement devices now exist.
Cruciate-Retaining As the name implies, this implant enables the surgeon to preserve the ligament. Choosing a Device There are a number of important factors that differentiate knee implants.
Mobile-Bearing Prosthesis femoral component not shown This prosthesis requires greater support from surrounding Orthopedic prothesis manufacturers tissues, including the ligaments. It offers a search tool that lets you enter your specific device and find out if a recall Orthopedic prothesis manufacturers taken place.
Studies show that about 97 percent of these implants remain in use after 20 years. This means a choice of only two or three different implants that vary in size. Orthopedic prothesis manufacturers, doctors often prefer this approach for younger patients because mobile-bearing devices are designed to accomodate a more active lifestyle and to last longer.
Zimmer Unicompartmental Uni-Knee Zimmer: When other medical handlings fail to recover the condition, orthopedic prosthesis are recommended by the doctor or surgeon. The additional support reduces the risk of dislocation. In the end, surgeons ensure that the bone and device fit together properly.

This fixed-bearing knee is designed to maximize stability. The manufacturer claims that the system provides degrees of posterior-stabilized flexion, degrees of cruciate-retailing flexion and degrees of cruciate-substituting flexion.
Personalized Systems Here are two examples of the personalized knee replacement systems available: It is virtuous to question the surgeon about the instruments to be used prior to surgery.
It offers 35 different sizing options. The most common material used to produce plastic components is ultra-high molecular weight polyethylene.
Whether or not a medical team uses a personalized guide, surgical planning is important and you should not hesitate to speak to your surgeon about it prior to surgery.
The design allows for the implant to flex, extend and rotate in a circular motion, much like your natural knee. Most devices consist of multiple components made from different medical-grade materials. Mobile-bearing prostheses allow the polyethylene insert to Orthopedic prothesis manufacturers short distances inside the metal tibial tray.
It is built with oxidized zirconium metal, making it more resistant to abrasion and scratching. Some surgeons use a combination of both methods. The manufacturer claims that the design reduces internal stress and wear.

The system uses an MRI or CT scan as well as 3D imaging software to view a computer simulation of the knee and create a unique surgical plan. It offers a high degree of flexion—typically about degrees—and is available in 90 different size combinations and 10 femoral size options to increase overall comfort.
Both were equally effective. Likewise, certain devices are best used in conjunction with certain surgical approaches. Unlike a TKR, a partial replacement requires removal of only part of the bone in the knee joint. Their prime purpose of orthopedic implants is to assist elongating the patient life by making him healthy and pain-free.
Fixation Method Surgeons use two types of methods to hold the prosthesis in place and bond the implant to your bone, allowing your leg and the implant to move as a single unit.
