Name of the Procedure:

Addition, Endoskeletal Knee-Shin System with Hydraulic Swing Phase Control

Common Names: Hydraulic Knee-Shin System, Prosthetic Knee with Hydraulic Swing Control

Technical Term: Endoskeletal Knee-Shin System, Single Axis, Hydraulic Swing Phase Control, with Miniature High Activity Frame

Summary

This procedure involves the addition of a specialized knee-shin system to a prosthetic limb. The unit includes hydraulic swing phase control, which helps to regulate the knee's movement while walking, providing a more natural gait. It is designed for high-activity users and includes a sturdy, compact frame.

Purpose

Medical Conditions:

• Amputations requiring a prosthetic limb with enhanced knee function.

Goals and Expected Outcomes:

• Improve mobility and functionality for individuals with above-knee amputations.
• Provide a smoother and more natural walking experience.
• Enhance the user's overall activity level and quality of life.

Indications

Symptoms and Conditions:

• Above-knee amputation requiring a highly functional prosthetic limb.

  Patient Criteria:

• High-activity individuals needing advanced prosthetic support.
• Patients who can benefit from enhanced knee control during walking.

Preparation

Pre-Procedure Instructions:

• No specific fasting or medication adjustments are typically required.
• A thorough assessment by a prosthetist to ensure proper fitting and suitability.

Diagnostic Tests:

• Gait analysis and biomechanical assessment.
• Evaluation of residual limb condition.

Procedure Description

Steps:

1. Assessment:
   • Comprehensive evaluation by the prosthetist to determine the specific needs and measurements.
2. Customization:
   • Custom design and fabrication of the knee-shin system.
3. Fitting:
   • Initial fitting of the prosthetic system to the residual limb.
4. Adjustment:
   • Fine-tuning of the hydraulic swing phase control for optimal performance.
5. Training:
   • Rehabilitation sessions to train the user on effectively using the new prosthetic limb.

Equipment and Technology:

• Endoskeletal knee-shin system with hydraulic swing phase control.
• Custom prosthetic fitting tools and software.

Anesthesia/Sedation:

• None required.

Duration

• The fitting and adjustment process may take several appointments, each lasting 1-2 hours.

Setting

• Outpatient clinic or specialized prosthetics and orthotics center.

Personnel

• Prosthetist
• Physical therapist (for gait training)
• Support staff

Risks and Complications

Common Risks:

• Skin irritation or pressure sores on the residual limb.
• Mechanical issues or malfunction of the hydraulic system.

Rare Risks:

• Prosthetic rejection.
• Infections due to improper hygiene.

Management:

• Regular follow-ups and adjustments.
• Proper hygiene and skin care instructions.

Benefits

Expected Benefits:

• More natural and smoother walking experience.
• Enhanced stability and mobility.
• Improved quality of life and ability to perform high-activity tasks.

Timeframe for Benefits:

• Benefits can often be realized immediately upon proper fitting and adjustment.

Recovery

Post-Procedure Care:

• Regular maintenance of the prosthetic limb.
• Follow-up appointments for adjustments.

Recovery Time:

• Immediate use post-fitting, with gradual improvement in proficiency over weeks to months.

Restrictions and Follow-Up:

• Minimal activity restrictions.
• Follow-up visits for fine-tuning and monitoring.

Alternatives

Other Treatment Options:

• Traditional mechanical knee prosthetics.
• Microprocessor-controlled knee prosthetics.

Pros and Cons:

• Traditional mechanical prosthetics: Lower cost, less advanced functionality.
• Microprocessor-controlled prosthetics: Advanced features, higher cost.

Patient Experience

During the Procedure:

• Typically no pain, as the procedure involves fitting and training rather than surgery.

After the Procedure:

• Initial period of adjustment and learning curve.
• Supportive care from the prosthetist and physical therapist to manage comfort and optimize performance.
