Name of the Procedure:

Common Name: Addition, Endoskeletal Knee-Shin System
Technical / Medical Term: Single-axis, pneumatic swing, friction stance phase control (L5822)

Summary

This procedure involves adding a specialized component to a prosthetic limb, specifically focusing on improving the functionality of the knee and lower leg segment. The technology used allows more natural movement for individuals with lower limb amputations by enhancing swing and stance control.

Purpose

Medical Conditions/Problems Addressed:

• Lower limb amputations, particularly above-knee amputations.
• Impaired mobility or difficulty with balance and walking.

Goals/Expected Outcomes:

• Enhanced knee and leg movement.
• Improved stability and comfort during walking.
• Increased mobility and independence for the patient.

Indications

Symptoms/Conditions Warranting the Procedure:

• Above-knee amputations requiring prosthetic enhancements.
• Difficulty in managing balance with current prosthetic technologies.
• Poor gait and posture with existing prosthetic systems.

Patient Criteria:

• Individuals currently using a prosthetic limb post-amputation.
• Patients experiencing mobility issues due to inadequate prosthetic control.

Preparation

Pre-procedure Instructions:

• No fasting or specific preparations usually required.
• Ensure the prosthetic limb is clean and functional.
• Patients may need to adjust any current medications under guidance.

Diagnostic Tests/Assessments:

• Physical assessment of limb and current prosthetic fitting.
• Gait analysis to identify specific mobility issues.
• Discussion with a prosthetist or orthopedic specialist.

Procedure Description

Step-by-Step Explanation:

1. The prosthetist examines the existing prosthetic limb.
2. Dismantling of the current knee and shin components if required.
3. Attachment of the endoskeletal knee-shin system.
4. Adjustments to ensure the pneumatic swing and friction stance control functions properly.
5. Testing and fine-tuning for optimal performance.

Tools and Equipment Used:

• Prosthetic limb components.
• Adjustment tools and fitting equipment.

Anesthesia or Sedation:

• Typically, none required as this is a non-invasive procedure.

Duration

The procedure usually takes between 1 to 2 hours.

Setting

Performed in an outpatient clinic, a prosthetic/orthotic center, or a specialized rehabilitation facility.

Personnel

• A certified prosthetist.
• Supportive medical staff as needed.

Risks and Complications

Common Risks:

• Minor discomfort or irritation during the adjustment phase.
• Temporary difficulties in movement as the patient adapts.

Rare Risks:

• Damage to the prosthetic limb requiring further repair.
• Misalignment causing discomfort or injury.

Possible Complications Management:

• Regular follow-up sessions for adjustments.
• Immediate care for any irritation or discomfort.

Benefits

Expected Benefits:

• Enhanced gait and ease of movement.
• Improved overall balance and posture.
• Increased comfort and reduced strain.

Realization Timeline:

• Benefits can often be noticed immediately, but optimal results may take several weeks.

Recovery

Post-procedure Care:

• Routine check-ups to ensure the system is functioning properly.
• Gradual increase in activity to adapt to the new system.

Expected Recovery Time:

• Usually, no lengthy recovery period; normal activities can often be resumed within a few days.

Restrictions and Follow-up:

• Follow-up appointments as needed for adjustments and assessments.

Alternatives

Other Treatment Options:

• Different types of prosthetic limb enhancements (e.g., hydraulic or microprocessor-controlled knees).
• Physical therapy alone without prosthetic enhancement.

Pros and Cons of Alternatives:

• Hydraulic or microprocessor-controlled knees can be more advanced but also more expensive.
• Physical therapy might not provide the desired improvement in mobility without prosthetic enhancement.

Patient Experience

During the Procedure:

• Minimal discomfort, mostly involving fitting and adjustments.
• No pain management typically required.

After the Procedure:

• Initial period of adaptation to the new system.
• Guidance provided on using and caring for the prosthetic component.
• Any discomfort managed through follow-up adjustments.
