Above knee amputation

Above knee amputation (AKA) is a surgical procedure that involves the removal of the leg above the knee joint. This type of amputation is typically performed when there is severe damage or disease in the lower limb that cannot be treated by other means.

Indications

Above knee amputation may be indicated for several reasons, including:

• Peripheral artery disease
• Severe trauma
• Infection that cannot be controlled
• Tumors or cancer in the lower limb
• Congenital limb defects

Procedure

The procedure is usually performed under general anesthesia. The surgeon makes an incision above the knee joint, removes the damaged tissue, and shapes the remaining limb to allow for the fitting of a prosthesis. The muscles and skin are then closed over the bone to create a stump.

Rehabilitation

Rehabilitation following an above knee amputation is crucial for recovery and includes:

• Physical therapy to strengthen the remaining limb and improve mobility
• Occupational therapy to help the patient adapt to daily activities
• Fitting and training with a prosthetic limb

Complications

As with any major surgery, there are potential complications, including:

• Infection
• Blood clots
• Phantom limb pain
• Difficulty with prosthetic fitting

Prosthetics

Prosthetic limbs for above knee amputees are more complex than those for below knee amputees due to the need to replicate the function of the knee joint. Modern prosthetics may include:

• Microprocessor-controlled knee joints
• Hydraulic knee joints
• Pneumatic knee joints

Psychological Impact

The loss of a limb can have a significant psychological impact. Support from mental health professionals, family, and support groups is often necessary to help the patient cope with the changes.
