Above-knee prosthesis systems are divided into two as modular and classic. Classical prostheses are not preferred except for their old users. Modular prostheses consist of a socket, knee joint, modular joints, and feet. The products used in the prostheses to be designed in the lower extremities vary depending on the amputation-residual limb status, the degree of activation of the patient and the expectations of the patient.Mobility level is one of the most important factors that determine the quality of life. Mobility requirements of someone who is not very active over a certain age and an athlete are quite different. For this reason, the products are chosen accordıing to individuals’ mobility levels. The person measuring the prosthesis assessment should guide the patient correctly during the selection of the correct prosthesis. In this classification, the function and the current situation (height weight) are integrated.

Symbyonic Bionic Leg
In Bionic leg prosthesis, high-level activity is provided with bionic Proprio used in knee prostheses on the foot part and symbionic prosthetic knee joint in the knee. Symbionic, is the first full bionic leg prosthesis in the world. Combining a servo motor foot unit and a knee joint that can adapt to a different floor and walking speeds, Symbionic, provides unique benefits for those using an above-knee prosthesis.
The active upward movement of the ankle that occurs when you step forward the prosthetic side (dorsiflexion) prevents contact of the prosthesis to the floor and minimizes the possible fall risks.
With the help of sensors, the automatic ground sensing feature provides better ground contact on ascending or decreasing ramps, optimizes support for the knee joint and adjusts the ankle angle according to the steepness of the slope.
The function of adjusting the heel height, which can be done by pressing a single button, eliminates the need to change the settings of the prosthesis in changing shoes, allowing the user with or without shoes to adapt to the ground on which they walk.

Rheo Electronic Knee Joint
Imagine a knee joint that adapts to the user’s walking style and the ground on which he walks, constantly learns and reacts to the action as soon as possible. Össur company offers RHEO KNEE knee joint, which provides microprocessor control at every moment of movement with the world’s first artificial intelligence power.
RHEO KNEE can think independently. It learns how the user walks, analyzes changes in speed-direction or ground and reacts as soon as possible. As with other knee joints, it does not adhere to the predetermined limited parameters, it adapts to the user in any condition, where, how and at what speed he wants to walk.
RHEO KNEE Performance advantages;;
Constant compliance – Artificial intelligence module, designed with extremely high technology, gives the knee joint self-thinking ability. It constantly recognizes, learns, adapts to different walking styles of the person and adapts to changes in speed, weight change, and ground structure.
Natural and effective action – Its special technology that controls knee movements produces an extremely natural and fast response at every stage of the walking cycle. Unlike hydraulic systems in other knee joints, this reaction can offer personalized resistance to the user’s need. In this way, while the effort spent on movement decreases, walking becomes much more fluid and natural.
Enhanced security – With its multi-security feature in software and mechanism, the knee resists against involuntary movements in critical moments. The sensor technology, which brings the information analyzed 1500 times per second at every moment of the walk to artificial intelligence, defines abnormal walking rhythms and protects the user against the potential risks of tripping and falling.
