How do Below -Knee prosthetic legs work? Also known as BK or transtibial. A below-knee prosthetic leg consists of the following: Custom made sockets, liner, pylon and foot. Every component of transtibial prostheses is designed to work together to ensure comfort and optimal function.

How do Above Knee prosthetics legs work? Also known as an AK or transfemoral prosthetic. An above knee prosthetic leg consists of the following: Custom made socket, liner, knee unit, pylon and foot. Depending on the nature of the amputation and the residual limb length, a transfemoral artificial leg may also include a prosthetic hip joint (if the entire leg was amputated).

    Microprocessor controlled devices can be either a knee or foot on a prosthesis. Patient results can be extraordinary with this computer-controlled device. Sensors, gauges, and gyroscopes relay information to the knee/foot which then apply the correct amount of friction/fluid in the  hydraulic, giving the patient a more energy-efficient gait pattern and an increased sense of security on various types of terrain.

NOP offers both passive, mechanical, and myoelectric prosthetic arms,  f. or both above elbow and below elbow amputees. Passive prosthetic arms have parts that are non-moving. A passive prosthetic arm can:

  • Have basic functionality that allows for pushing and pulling actions, as well as supporting and stabilizing motions.
  • Be designed with special joints so the arm can hold and carry objects.
  • Be fabricated to match skin tone.

Mechanical prosthetic arms  along with myoelectric allow the patient to regain function after limb loss. Mor myoelectric/bionic prosthetic arms have moving parts that work via sensor and electrodes.

  • Body powered prosthetics utilize the body’s musculature and motion with the use of cables to function mechanical elbows and hands, depending on the amputation level.
  • Myoelectric prosthetics utilize electrodes that sense muscle movement to operate elbow and/or hand depending on the the amputation site.
  • Also we can provide a hybrid prosthetic which utilize body powered and myoelectric features to function hand and/or elbow depending on the amputation site.


At NOP, we work with children of all ages who were born with a missing or partial limb, or who lost a limb due to injuries or illness. Our team strives to not only provide each child with a custom prosthesis to improve mobility but also takes special care that the process results in greater confidence and a healthy self-image. ​

From the first consultation through prosthetics fittings and follow-ups, we work to create a caring and comfortable environment for you and your child. Since children are constantly growing, discovering new activities, or looking for greater independence, we offer ongoing services to modify, upgrade, repair, or replace their prosthetics.

We design, fabricate and fit a variety of prosthetic devices for children, adolescents, and young adults, including:

  • Above-knee prosthetic legs
  • Below-knee prosthetic legs
  • Passive, myoelectric/bionic, and mechanical prosthetic arms
  • Sport Specific prosthetics
  • And more…

We don’t just send our young patients on their way. We help children and their parents learn, adapt, and become confident with their new prosthetic.


Many of our patients are active people with a healthy lifestyle. Some are even world-class athletes. Either way, NOP has a long history of offering the best custom sports prosthetics available today. Whether you’re into running, cycling, swimming, skiing, rowing, golfing, surfing, kickboxing, soccer, or virtually any other sport, we’ve got you covered.
