Knee Joint01:23

Knee Joint

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 group...
Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...
Bones of the Lower Limb: Tibia and Fibula01:10

Bones of the Lower Limb: Tibia and Fibula

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...
Ankle Joint01:10

Ankle Joint

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...

Summary
This summary is machine-generated.

Knee disarticulation offers superior outcomes compared to transfemoral amputation by preserving muscle function and hip mobility. This advanced amputation technique allows for better prosthetic fitting and improved mobility for amputees.

Area of Science:

  • Orthopedic surgery
  • Reconstructive surgery
  • Prosthetics and orthotics

Context:

  • Knee disarticulation is an alternative to transfemoral amputation.
  • Preserves knee joint function and thigh musculature.
  • Suitable for various etiologies, including infected total knee replacements.

Purpose:

  • To evaluate the benefits of knee disarticulation over transfemoral amputation.
  • To highlight the surgical technique and postoperative management.
  • To discuss the functional outcomes and prosthetic fitting.

Summary:

  • Knee disarticulation preserves thigh muscles, maintaining hip range of motion and muscle balance.
  • The procedure is atraumatic, avoiding bone and muscle division, and allows for weight-bearing on the stump.
  • Postoperative prosthetic fitting is feasible within 3-6 weeks, with outcomes superior to transfemoral amputations, especially in athletic activities.

Impact:

  • Knee disarticulation leads to better functional performance and quality of life for amputees.
  • It offers a viable solution for complex cases, including failed knee replacements.
  • Preserving the knee joint through disarticulation enhances prosthetic integration and patient mobility.
