Above Knee Prosthesis for Proximal Femoral Focal Deficiency (PFFD), Constant Friction Knee, Shin, SACH Foot (L5230)

Name of the Procedure

Above Knee Prosthesis

• Technical Name: Above Knee Prosthesis for Proximal Femoral Focal Deficiency (PFFD), Constant Friction Knee, Shin, and SACH Foot
• Common Names: Above Knee Prosthesis, Above Knee Artificial Limb

Summary

This procedure involves fitting a patient with an artificial limb above the knee. It is designed for individuals with Proximal Femoral Focal Deficiency (PFFD), a condition where the femur bone in the thigh is underdeveloped. The prosthesis includes a constant friction knee, shin, and Solid Ankle Cushion Heel (SACH) foot.

Purpose

The procedure aims to:

• Provide mobility and improve the ability to walk.
• Enhance personal independence and quality of life.
• Address functional limitations due to PFFD.

Indications

• Diagnosed PFFD causing significant mobility impairment.
• Inadequate development of the femur requiring support and artificial limb fitting.
• Patients suitable for prosthetic support who have completed growth or have a stable residual limb.

Preparation

• Pre-fitting consultation with a prosthetist and physician.
• Measurements and molds of the residual limb.
• Possible imaging tests (X-rays, MRIs) to assess the residual limb structure.
• No specific fasting or medication adjustments required unless directed by a physician.

Procedure Description

1. Initial Consultation:

   • Evaluate patient's residual limb and overall health.
   • Discuss patient needs, lifestyle, and goals.

2. Prosthetic Design:

   • Custom design the prosthetic limb based on measurements and patient requirements.

3. Fitting:

   • Create a test socket and adjust for comfort and function.
   • Ensure proper alignment and balance of the prosthetic components.

4. Final Assembly:

   • Fit the constant friction knee, shin, and SACH foot to the prosthetic.
   • Final adjustments for optimal use.

Duration

• Initial fitting and consultation: 1-2 hours.
• Subsequent adjustments and fittings over a few weeks.

Setting

• Prosthetist clinic or specialized orthopedic center.

Personnel

• Certified Prosthetist.
• Rehabilitation Specialist.
• Physician for medical assessment.
• Nurses for support and care.

Risks and Complications

• Skin irritation or pressure sores.
• Infections at the residual limb site.
• Misalignment causing discomfort or imbalance.
• Prosthetic malfunction requiring adjustment.

Benefits

• Improved mobility and ability to perform daily activities.
• Enhanced independence and quality of life.
• Better cosmetic appearance and self-esteem.
• Functional gait with less energy expenditure.

Recovery

• Initial adaptation period of several weeks to months.
• Regular follow-up appointments for adjustments.
• Gradual increase in activity level as comfort and confidence improve.
• Physical therapy for gait training and muscle strengthening.

Alternatives

• Wheelchair or mobility scooter for severe cases.
• Other prosthetic designs based on the patient’s condition and preference.
• Surgical interventions for limb lengthening or reconstruction.

Patient Experience

• Initial discomfort as the body adapts to the new limb.
• Emotional and psychological adjustment with support from healthcare professionals.
• Pain management as needed with medications or therapy.
• Gradual improvement in mobility and confidence with continued use.

This procedure provides a viable option for individuals with PFFD to regain mobility and improve their quality of life significantly.
