Knee disarticulation offers a muscle-balanced amputation solution for patients with diabetes, vascular disease, or trauma. This level provides a stable residual limb for end-bearing and transfers, improving mobility and function.

Area of Science:

  • Orthopedic Surgery
  • Prosthetics and Orthotics
  • Rehabilitation Medicine

Background:

  • Knee disarticulation is a viable amputation level for diverse patient populations including those with diabetes, peripheral vascular disease, and trauma.
  • This amputation level preserves sitting ability, facilitating transfers and reducing contracture risk.
  • It provides a well-padded residual limb for end-bearing, crucial for ambulatory patients with vascular disease or trauma.

Purpose of the Study:

  • To highlight the benefits of knee disarticulation as an amputation level.
  • To discuss its suitability for patients with specific medical conditions and trauma.
  • To emphasize the functional advantages for sitting, transfers, and ambulation.

Main Methods:

  • Review of clinical applications and patient outcomes associated with knee disarticulation.

  • Analysis of biomechanical advantages, including residual limb characteristics and prosthetic joint utilization.
  • Evaluation of patient populations benefiting from this amputation level.

    • Main Results:

    • Knee disarticulation provides a stable base for sitting and transfers, minimizing joint contracture development.
    • Ambulatory patients, especially those with vascular disease or trauma, benefit from a well-padded residual limb enabling distal end-bearing.
    • The integration of a four-bar linkage prosthetic knee joint enhances intrinsic stability during walking.

    Conclusions:

    • Knee disarticulation is a muscle-balanced amputation level offering significant functional benefits for selected patients.
    • It promotes improved mobility, end-bearing capacity, and prosthetic joint stability.
    • This level is advantageous for patients with diabetes, peripheral vascular disease, trauma, and those requiring effective transfer and sitting capabilities.
