Ankle Joint01:10

Ankle Joint

3.8K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Development of the Limb Synovial Joints

2.7K
Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
During development, the limbs...

Knee Joint01:23

Knee Joint

3.8K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

    Area of Science:

    • Biomechanics
    • Prosthetics Engineering
    • Rehabilitation Technology

    Background:

    • Transtibial amputees experience residual limb stress due to socket forces.
    • Current prosthetic designs often focus on mimicking normal joint motion, which may not optimize gait or comfort.
    • Reducing socket moment is crucial for improving user experience and prosthetic longevity.

    Purpose of the Study:

    • To present simulations of a novel powered ankle prosthesis.
    • To investigate the prosthesis's ability to dynamically align the tibia with the ground reaction force (GRF) vector.
    • To assess the potential reduction in socket moment and its effects on the residual limb, pelvis, and contralateral knee.

    Main Methods:

    • Forward dynamics simulations were employed to model the powered ankle prosthesis.
    • The simulation focused on the peak loading phase of gait.
    • The dynamic alignment of the tibia relative to the GRF vector was a key simulation parameter.

    Main Results:

    • Simulations demonstrated a significant reduction in socket moment during peak loading.
    • The dynamic alignment strategy showed a decreased impact on the pelvis and affected-side knee.
    • The novel design shows promise in mitigating undesirable forces transferred to the residual limb.

    Conclusions:

    • The simulated powered ankle prosthesis effectively reduces socket moment by dynamically aligning the tibia.
    • This approach offers a potential improvement over designs solely mimicking physiological joint motion.
    • Further research into this prosthetic design could enhance gait optimization and user comfort for lower limb amputees.
