Name of the Procedure:

• Common Name: Adjustable Knee or Ankle Mechanism Addition
• Technical Term: Addition to Lower Extremity Joint, Knee or Ankle, Concentric Adjustable Torsion Style Mechanism for Custom Fabricated Orthotics (L2861)

Summary

This procedure involves adding an adjustable torsion mechanism to a custom-made orthotic device designed for the knee or ankle. The mechanism allows for precise adjustments to improve movement and stability.

Purpose

• Addresses conditions such as joint instability, weakness, or movement disorders in the knee or ankle.
• Goals include improving joint function, mobility, and stability, thereby enhancing the patient's quality of life.

Indications

• Symptoms: Joint instability, difficulty walking, or abnormal gait.
• Conditions: Osteoarthritis, post-surgical recovery, neurological disorders affecting muscle control.
• Criteria: Patients requiring custom orthotics for improved joint support and motion control.

Preparation

• Pre-procedure instructions: No specific fasting or medication adjustments typically required.
• Diagnostic tests: Physical examination, gait analysis, and potentially imaging studies (e.g., X-rays, MRI) to plan the orthotic design.

Procedure Description

1. Custom orthotic device is fabricated specifically for the patient's lower extremity.
2. The adjustable torsion mechanism is integrated into the orthotic, focusing on the knee or ankle.
3. The device is tested and adjusted for optimal comfort and functionality.
4. The patient is trained on how to properly use and adjust the orthotic mechanism.

• Tools and Equipment: Custom orthotic materials, adjustable torsion mechanism.
• No anesthesia or sedation is usually required, as the procedure is non-invasive.

Duration

The entire process, from orthotic design to fitting, may take several weeks. The fitting and adjustment session typically lasts 1-2 hours.

Setting

• Outpatient clinic specializing in orthotics and prosthetics.

Personnel

• Orthotist, who specializes in custom orthotic devices.
• Physical therapist, for training and gait assessment.
• Physician or specialist overseeing the treatment plan.

Risks and Complications

• Common risks: Initial discomfort, irritation, or pressure sores from the orthotic.
• Rare risks: Mechanical failure of the torsion mechanism, improper fit leading to exacerbation of symptoms.
• Management: Regular follow-up and adjustments, proper patient education on use.

Benefits

• Improved joint function and stability.
• Enhanced mobility and gait.
• Benefits typically realized within a few weeks of consistent use and adjustment.

Recovery

• Post-procedure care: Regular wear of the orthotic as recommended, cleaning and maintenance of the device.
• Recovery time: Varies according to individual progress, generally a few weeks to adapt.
• Follow-up: Regular check-ins for adjustments.

Alternatives

• Other treatment options: Physical therapy, surgical intervention, non-custom orthotic braces.
• Pros and Cons: Physical therapy is less invasive but may provide less support. Surgery is more definitive but has higher risks. Non-custom braces are more accessible but may not offer the same level of support.

Patient Experience

• During the procedure: Patients may feel pressure but no significant pain.
• After the procedure: Initial discomfort is possible as the body adjusts. Consistent use and follow-up adjustments should alleviate this.
• Pain Management: Over-the-counter pain relief if necessary and usage instructions to mitigate discomfort.
