\nThe hyper flexible joint or three-dimensional joint is a technology that aims to install an artificial knee joint that mimics the natural joint, so that the patient can fully bend the knee and perform prayer normally.<\/span><\/p>\n

Cases of resorting to the installation of a highly flexed joint<\/span><\/p>\n

Doctors resort to replacing the knee joint if the joint erodes as a result of one of the following reasons:<\/span><\/p>\n

\u00a0\u00a0\u00a0\u00a0\u00a0Osteoarthritis<\/span><\/p>\n

\u00a0\u00a0\u00a0\u00a0\u00a0It often affects the elderly.<\/span><\/p>\n

\u00a0\u00a0\u00a0\u00a0\u00a0Rheumatic osteoarthritis.<\/span><\/p>\n

\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0Severe knee injuries resulting from an accident or violent collision.<\/span><\/p>\n

Advantages of installing a highly bent joint<\/span><\/p>\n

The highly flexed joint (three-dimensional) restores the natural movement of the knee joint, as it allows the patient to fully flex the knee to 120 degrees, which is the degree the patient needs to pray without feeling pain, sit on the ground, and exercise without suffering.<\/span><\/p>\n

Unlike the ancient joint structure, which did not provide such a wide range of motion for the joint, the patient could not fully bend the knee, and therefore it was difficult to prostrate in prayer or sit on the ground.<\/span><\/p>\n

The process of installing a highly bent joint<\/span><\/p>\n

The process of installing a knee joint aims to install an artificial joint that looks exactly like a natural joint. Any error while determining its dimensions will limit its lifespan. With medical progress, two techniques have emerged that are used in installing an artificial knee joint:<\/span><\/p>\n

\u00a0\u00a0\u00a0\u00a0\u00a0Navigation technology<\/span><\/p>\n

The navigation technique contributes to accurately determining the dimensions of the joint, during which the doctor does the following:<\/span><\/p>\n

\u00a0\u00a0\u00a0\u00a0\u00a0Metal markers are installed on the femur and shin bones through small surgical incisions.<\/span><\/p>\n

\u00a0\u00a0\u00a0\u00a0\u00a0Using a computer equipped with cameras that can photograph mineral marks and capture many points on the surface of the bones.<\/span><\/p>\n

\u00a0\u00a0\u00a0\u00a0\u00a0Based on the images and points captured by the camera, the computer can determine the shape and dimensions of the bones to help determine the optimal position for installing the artificial joint.<\/span><\/p>\n

The above steps are performed during the surgical procedure, which may increase the operation time, which is the main disadvantage of this technique.<\/span><\/p>\n

\u00a0\u00a0\u00a0\u00a0\u00a0Patient-Specific Instrumentation technology<\/span><\/p>\n

This technology came to save time in the surgical procedure by taking measurements of the knee bones using CT scans before surgery, and then manufacturing plastic molds – or electronic molds – that fit the shape of the knee bones before the surgical procedure. During surgery, the doctor attaches these templates with metal pins to mark the locations of bone removal.<\/span><\/p>\n

Although the goal of mold technology is to reduce surgical time, the time it takes to manufacture these plastic molds may reach up to 6 weeks, so this technique is not widely used.<\/span><\/p>\n

The highly flexed joint or 3D joint technique is used in complex cases due to its high cost.<\/span><\/p>\n

There are many techniques, and the goal remains to install an artificial joint that mimics the natural knee joint, for longer life of the joint and a natural range of motion.<\/span>
