Name of the Procedure:

Addition, Endoskeletal System, High Activity Knee Control Frame (HCPCS Code: L5930)

Common name(s): High Activity Knee Control Frame, Advanced Knee Brace Technical/medical term: Endoskeletal system with high activity knee control

Summary

This procedure involves the addition of a specialized endoskeletal system component, specifically a high-activity knee control frame, to a prosthetic limb. The enhancement is designed to offer improved knee stability and control for individuals who require high activity levels, such as athletes or active individuals with above-knee amputations.

Purpose

The high-activity knee control frame is intended for individuals who need enhanced mobility and stability in their prosthetic knee. It aims to provide better support and control during vigorous activities, reducing the risk of falls and improving overall function and quality of life.

Indications

• Individuals with above-knee amputations who participate in high-impact or high-activity sports and exercises.
• Patients who experience instability or difficulty with standard knee prosthetics during vigorous activities.
• Individuals who require greater control and support to perform daily activities safely and efficiently.

Preparation

• Patients may need to undergo a physical examination and gait analysis to determine the suitability of the high-activity knee control frame.
• Diagnostic tests, such as imaging studies, may be required to assess residual limb health and overall physical condition.
• Patients should follow specific instructions from their healthcare provider regarding medication adjustments or other preparatory steps.

Procedure Description

1. The fitting process begins with a comprehensive evaluation by a prosthetist.
2. The prosthetist will select and customize the high-activity knee control frame to fit the patient's prosthetic limb.
3. Adjustments are made to ensure proper alignment, comfort, and functionality.
4. The frame is then attached to the existing endoskeletal system of the prosthetic limb.
5. Testing and fine-tuning are performed to ensure the knee control frame operates as intended.

Tools/Equipment:

• High-activity knee control frame
• Endoskeletal prosthetic limb components
• Fitting and adjustment tools

Anesthesia or Sedation:

• Typically not required for the fitting procedure.

Duration

The entire fitting and adjustment process can take several hours, typically ranging from 1 to 4 hours.

Setting

The procedure is usually performed in a specialized prosthetics and orthotics clinic.

Personnel

• Prosthetist
• Physical Therapist (optional, for gait training and assessment)

Risks and Complications

Common Risks:

• Initial discomfort or irritation at the attachment site
• Temporary difficulties with gait Rare Risks:
• Mechanical failure or malfunction of the knee control frame
• Pressure sores or skin breakdown due to improper fit

Management:

• Regular follow-up visits for adjustments and maintenance
• Immediate consultation with the prosthetist if discomfort or mechanical issues arise

Benefits

• Enhanced stability and control during high-impact activities.
• Improved safety, reducing the risk of falls and injuries.
• Increased confidence in performing daily and recreational activities.
• Better overall function and mobility.

Recovery

• Post-fitting, patients may experience a short adaptation period.
• Physical therapy may be recommended to optimize gait and usage.
• Regular follow-up appointments to monitor fit and function.
• No significant restrictions after fitting, but ongoing care and adjustments may be necessary.

Alternatives

• Traditional prosthetic knee systems (may offer less stability for high-impact activities).

• Microprocessor-controlled knee systems (can provide advanced features but may be cost-prohibitive).

  Pros and Cons:

• Traditional Systems: Less expensive but may not offer the same level of support.
• Microprocessor Systems: Advanced functionality and improved control but higher cost and maintenance.

Patient Experience

During the Procedure:

• Mild discomfort during the fitting process.

After the Procedure:

• Some initial muscle fatigue as the body adapts to the new system.
• Improvement in stability and mobility, typically recognized within days to weeks.
• Pain management involves over-the-counter pain relievers and consulting a prosthetist for fit issues.
