What is disarticulation at knee?
Knee disarticulation is a muscle balanced amputation level that can be used in patients with diabetes, peripheral vascular disease, and trauma. Patients who are capable of sitting in a chair retain an excellent platform for sitting, a lever arm for transfer, and are unlikely to have joint contractures develop.
Is disarticulation the same as amputation?
Surgical technique: Knee disarticulation is a very atraumatic procedure, compared to transfemoral amputations. Neither bones nor muscles have to be severed, just skin, ligaments, vessels, and nerves. Even the meniscal cartilages may be left in place to act as axial shock absorbers.
Where is a disarticulation amputation done?
Knee Disarticulation Amputations: This amputation occurs at the level of the knee joint. If a surgeon can’t perform the amputation below the knee, he or she will consider knee disarticulation, an amputation of the knee joint that leaves the femur and patella untouched and does not cut through bone or muscle.
How much does a knee prosthetic cost?
If you want a basic, below-the-knee prosthetic, the average cost is around $3,000 to $10,000. A more flexible, below-the-knee prosthetic costs a little bit more, while one with special hydraulic and mechanical assistance ranges between $20,000 and $40,000. The computerized leg is the priciest option.
What is a disarticulation amputation?
An elbow disarticulation amputation allows anatomic suspension, rotational control of the prosthesis, and reduces rotation of the socket on the residual limb. The major disadvantages are the suboptimal cosmetic appearance and limited availability of elbow components.
What is disarticulation prosthesis?
Hip-disarticulation prostheses (HDPs) are used by amputees with either an amputation or anomaly at or close to the hip joint. Robotics can be beneficial in such cases, as these individuals have reduced levels of motor function compared to other amputees and have limited mobility.
What is disarticulation surgery?
Frederick L. Hampton, C.P. Hip disarticulation is the surgical removal of the entire lower limb by transection through the hip joint. Transpelvic amputation is the surgical removal of the entire lower limb plus all or a major portion of the ilium.
How does disarticulation occur?
There are three distinct causes of hip disarticulation: vascular disease, trauma, and malignancy. Vascular impairment, whether or not associated with diabetes mellitus, is the most common cause of lower limb loss in the industrialized world.

What is the difference between avulsion and amputation?
What is the difference between an avulsion and an amputation? A1. An avulsion is a tearing or forcible separation of tissue. An amputation is loss or removal of a limb, body part or organ.
What are the levels of amputation?
Levels of Amputation
- Forequarter.
- Shoulder Disarticulation (SD)
- Transhumeral (Above Elbow AE)
- Elbow Disarticulation (ED)
- Transradial (Below Elbow BE)
- Hand/ Wrist Disarticulation.
- Transcarpal (Partial Hand PH)
How does knee disarticulation work for nonambulatory patients?
In patients who are nonambulatory, knee disarticulation is a muscle balanced amputation with very little potential for the late development of hip or knee joint contracture. The residual limb provides an excellent platform for wheelchair sitting, and an efficient lever arm for transfer from bed to chair ( Figs 1, 2 ).
Which is better knee disarticulation or through knee stump?
Objective: A knee disarticulation or a through-knee stump is superior compared to a transfemoral stump. The thigh muscles are all preserved, and the muscle balance remains undisturbed. The range of motion of the hip joint is not limited.
How is skin grafting used for knee disarticulation?
Functional prosthetic limb fitting at the knee disarticulation level requires retention of sufficient gastrocnemius muscle to act as a weightbearing cushion. Because minimal shear forces are applied to the knee disarticulation residual limb, split thickness skin grafting can be used over muscle in weightbearing areas in the patient with trauma.
How often does knee disarticulation occur in the US?
Most demographic surveys suggest that the frequency of knee disarticulation in the United States is between 1% and 2% of all major lower-limb amputations. The incidence appears to be similar in many other countries but gradually increases to about 20% in centers that advocate this level, such as those in Copenhagen and Toronto.
