Ankle Joint01:10

Ankle Joint

1.7K
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...

Bones of the Lower Limb: Tibia and Fibula

4.2K
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...

Knee Joint01:23

Knee Joint

2.0K
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...

Development of the Limb Synovial Joints01:07

Development of the Limb Synovial Joints

1.5K
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...

Area of Science:

  • Orthopedic surgery
  • Biomechanics
  • Medical device technology

Context:

  • The ankle joint bears significant body weight, making it susceptible to arthrosis from incongruities, instabilities, and deformities.
  • Ankle arthrodesis (fusion) has been the standard for end-stage arthrosis, but modern advancements offer alternatives.
  • Current surgical options for ankle joint conditions are rapidly evolving.

Purpose:

  • To evaluate the evolving role of ankle arthroplasty in treating end-stage ankle arthrosis.
  • To highlight the advancements in ankle joint prostheses and implantation techniques.
  • To emphasize the importance of proper surgical planning and patient selection for successful outcomes.

Summary:

  • Third-generation (3-component) and fourth-generation (2-component) ankle prostheses demonstrate excellent results.
  • Simplified implantation techniques are broadening surgeon access to ankle arthroplasty.
  • Increasing implantation rates reflect the growing acceptance and efficacy of modern ankle replacements.

Impact:

  • Ankle arthroplasty is becoming a more viable option alongside traditional arthrodesis for end-stage ankle arthrosis.
  • Improved surgical techniques and implant designs are enhancing treatment options for patients with ankle joint degeneration.
  • Careful preoperative planning, patient selection, and precise surgical execution are crucial for optimizing postoperative success in ankle replacement surgery.
