Name of the Procedure:

Addition to Endoskeletal Knee-Shin System, Fluid Stance Extension, Dampening Feature, With or Without Adjustability (L5848)
Common Name(s): Knee-Shin Prosthetic Update, Fluid Dampening Knee Prosthesis

Summary

This procedure involves upgrading an endoskeletal knee-shin system with a fluid stance extension and a dampening feature. This means adding advanced components to a prosthetic leg to improve its functionality and comfort.

Purpose

Medical Conditions Addressed:

• Lower limb amputation
• Prosthetic leg users requiring improved stability and mobility

Goals and Outcomes:

• Enhance stability during stance phase of walking
• Provide smoother and more controlled movements
• Improve overall comfort and confidence for the user

Indications

Symptoms and Conditions:

• Users with existing endoskeletal knee-shin prostheses experiencing instability
• Patients requiring more adaptive and responsive prosthetic knee functions

Patient Criteria:

• Patients cleared for prosthetic upgrades by their healthcare provider
• Individuals with sufficient physical capacity to benefit from advanced prosthetic features

Preparation

Pre-Procedure Instructions:

• No specific fasting required
• Review of the current prosthetic setup and patient’s physical condition
• Potential gait analysis and fitting assessments

Diagnostic Tests:

• Evaluation by a prosthetist and/or physical therapist
• Possible imaging studies if necessary to assess the residual limb

Procedure Description

Steps Involved:

1. Assessment of the existing prosthesis and patient-specific needs by a prosthetist.
2. Detachment of the existing knee-shin components.
3. Installation of the new fluid stance extension and dampening feature.
4. Adjustment of the prosthetic alignment and calibration of the new components.
5. Functional testing with the patient to ensure optimal fit and performance.

Tools and Technology:

• Prosthetic alignment tools
• Fluid stance extension unit
• Dampening mechanism system

Anesthesia:

• Usually none required, as it is a non-surgical procedure

Duration

• Typically 1 to 2 hours, depending on complexity

Setting

• Prosthetic clinic or hospital specialized in prosthetics and orthotics

Personnel

• Certified Prosthetist
• Physical Therapist (for post-procedure gait training)

Risks and Complications

Common Risks:

• Initial discomfort or adjustment period
• Minor skin irritation at the interface

Rare Complications:

• Component failure or malfunction
• Misalignment requiring readjustment

Management:

• Regular follow-ups for adjustments
• Potential component replacements if necessary

Benefits

Expected Benefits:

• Increased stability and smoother movements
• Enhanced comfort and reduced fatigue

Realization Time:

• Immediate improvement in mobility noticed; full acclimatization in a few weeks

Recovery

Post-Procedure Care:

• Wear the upgraded prosthetic as advised
• Engage in physical therapy for optimal use

Recovery Time:

• Generally brief, with most users adjusting within a few days to weeks

Restrictions:

• None significant; follow specific guidance on activity levels initially

Follow-Up:

• Regular check-ups to ensure proper functioning and alignment

Alternatives

Other Treatment Options:

• Stick with the current prosthetic components
• Consider alternative prosthetic systems, like microprocessor-controlled knees

Pros and Cons:

• Pros of the Described Procedure: Enhanced stability, smoother gait
• Cons of Alternatives: May not provide the same level of adaptive support and comfort

Patient Experience

During Procedure:

• Minimal discomfort, akin to a fitting session

After Procedure:

• Possible minor discomfort during initial usage
• Overall improved confidence and comfort in walking

Pain Management:

• Usually not necessary; over-the-counter pain relievers if any discomfort occurs
