Socket Section
This socket is designed with an inner flexible socket and an outer laminated resin frame. The flexible socket is designed to be fitted around your ischium and ramus which are part of your pelvic skeletal anatomy. This creates a “bony lock” to stabilize the socket during walking and standing. The socket also has anatomical contours designed to support your muscular anatomy to provide control, weight bearing, and support.
This socket is also designed with an inner flexible socket and outer laminated resin frame. The Musculoskeletal socket does not fit around your pelvic anatomy like an Ischial weight bearing socket. It provides four longitudinal struts that support the entire femur and allows muscle and soft tissue expansion to displace properly through uniquely designed windows. This biomechanical design provides improved socket control, suspension, and comfort. It does not fit into the groin as do other socket systems so it allows greater movement with improved comfort when walking and sitting.
This socket is also designed with and inner flexible socket and outer laminated frame. The trim lines are much lower that both the Ischial containment and HiFi sockets. This socket requires the use of liners and vacuum to create tissue firmness and provide support and suspension. It is best used on a patient with a longer and more firm residual limb. The socket provides for increased range of motion and improved comfort when walking and sitting.
This socket system is designed to provide weight bearing and support evenly over the surface of the residual limb. It requires the patient to wear a silicone or urethane liner on the residual limb. It is suspended with either passive suction or elevated vacuum. The combination of total support, the liner, and suction suspension, provide a socket that is very comfortable, provides excellent biomechanical control, and allows improved function.
This is the traditional below knee prosthetic socket. It is designed with specific weight bearing areas. These are the patella tendon, which is just below your knee cap, either side of your tibia, and the inside and back of your calf. This socket design is generally used when patients wear a pin lock or traditional strap suspension.

Knee Section
Patients who are not that active and do very little walking may only require a knee that provides a high level of support and is lightweight. This type of knee may have a manual lock which provides the highest level of support. Low activity knees are designed for the individual who only walk short lengths in their home and at slow speeds. These patients generally require the additional support of a walker or cane.
The medium activity knee is designed for the patient who has good balance and can walk at different speeds. This type of knee provides stability mechanically without a lock and can adjust to walking speed with the use of hydraulic units. These knees can be mechanical or microprocessor in design. These patients generally do not require the use of additional support.
The high activity knee is designed for the patient who has very good balance and can walk at various speeds as well as run. They not only walk long distances but engage in higher activities such as basketball, weight training, tennis, golf, as well other demanding activities. They require a knee that will keep up with them and can adjust walking speeds and support modes quickly. They also need a knee that can have a few function modes they can choose from.
Some patients require a knee that is designed for a specific function. This might be running or swimming. There are knee options available for these patients. Many of these knees are function specific and may not be usable for everyday walking.
These  knees are designed with a microprocessor that controls the knee movement more efficiently than conventional knees.They allow you to walk with a more natural efficient gait. The knee provides extreme stability when needed also has stumble recovery. Depending in the knee unit patients can choose a few different knee settings for various activities with the use of a fob or app. These settings can be programmed for cycling, golfing, or many other functions patient may desire.

Feet Section
Lower activity feet are designed for a patient who does limited walking. They are lighter in design and require less energy to walk with. These types of feet are designed to mainly provide support during standing. They can be fabricated with outer rubber material to create the foot shape and have inner wooden or light plastic support structure commonly referred to a keel.
Medium activity feet are designed for your more active household and community ambulator. They are designed with an energy storing inner keel made from carbon fiber, fiberglass, or another type of dynamic material. The dynamic keel absorbs energy as you walk on the foot, like a spring. Once you unload or take weight off the foot during walking the energy absorbed helps propel you forward. This action helps increase functional activity and reduce energy consumption.
The higher activity feet also have energy storing function like the medium activity foot but allow much more movement. They are designed for the patient who walks at different speeds and perform activities such as running, tennis, basketball, etc. These feet allow movement in different directions working to mimic the movement of your natural foot. Some also have designs that will absorb shock and rotation during high activity function. The addition of this increased movement makes walking and running with the prosthetic foot more natural and increases the comfort of the device as well.  The function of the foot is in the design of the inner foot. They are made with an external foot shell to allow the foot to fit into your shoe.
Quite often patients will engage in activities that require a specific foot design. This could be for extreme sports, running marathons, swimming, etc. We can choose feet that can help you meet these personal and very specific needs. These feet are designed for a specific goal and may not be functional for everyday walking.
Some of the newer advanced feet have hydraulic mechanisms in the ankle that are self-adjusting during your walking. These ankles create a smooth and very natural waking pattern. Feet with microprocessor units that assist the hydraulic ankle are becoming more common as well. The microprocessor foot has sensors that can adjust the foot according to how you are walking. These type of ankle systems require that you be fitted with a suction socket to function properly. These are generally provided to patients with medium to high functioning activity level.
