    Summary
    This summary is machine-generated.

    Knee disarticulation is a superior alternative to above-knee amputation when below-knee amputation is not possible. This limb-sparing procedure offers better prosthesis fit, function, and comfort for patients.

    Area of Science:

    • Orthopedic Surgery
    • Prosthetics and Orthotics
    • Rehabilitation Medicine

    Background:

    • Below-knee amputation is not always feasible.
    • Above-knee amputation can lead to muscular imbalance and prosthetic challenges.

    Purpose of the Study:

    • To evaluate knee disarticulation as an alternative to above-knee amputation.
    • To highlight the advantages of knee disarticulation for limb salvage and prosthetic fitting.

    Main Methods:

    • Surgical technique for knee disarticulation preserving femur and patella.
    • Development of specialized double-wall sockets and knee joints.
    • Clinical evaluation of 72 patients across all age groups.

    Main Results:

    • Knee disarticulation is a simple, non-traumatic procedure.

  • Preservation of thigh muscles prevents muscular imbalance.
  • Stumps allow for total end bearing and secure prosthesis attachment.
  • Modern prostheses offer improved function, comfort, and cosmesis compared to above-knee options.

    • Conclusions:

    • Knee disarticulation should be prioritized over above-knee amputation when below-knee amputation is not possible.
    • This technique provides significant functional and prosthetic advantages for amputees.
