Name of the Procedure:

• Common Name: Knee Joint Lift Loop Addition
• Technical Term: Addition to Knee Joint, Lift Loop for Drop Lock Ring (HCPCS L2492)

Summary

This procedure involves the addition of a lift loop to a knee joint with a drop lock ring. It is often performed to enhance the functionality and usability of knee orthotics, making it easier for the patient to lock and unlock the knee joint.

Purpose

• Medical Conditions/Problems Addressed: This procedure is designed to assist patients who suffer from lower limb disabilities that make it difficult to control the knee joint.
• Goals/Expected Outcomes: To provide improved mobility and ease of use with knee orthotics, leading to better patient independence and quality of life.

Indications

• Symptoms/Conditions: Patients with knee instability, drop foot, or other lower limb conditions that require the use of knee orthotics.
• Patient Criteria: Individuals who have difficulty manually locking or unlocking the knee joint and would benefit from an additional mechanical aid.

Preparation

• Pre-Procedure Instructions: Generally, no special preparation is necessary, but the patient should discuss any current medications with their doctor.
• Diagnostic Tests/Assessments: A thorough assessment of the patient’s mobility and current orthotic device may be conducted to ensure the procedure is appropriate.

Procedure Description

1. The patient is positioned comfortably, usually seated or lying down.
2. The existing knee orthotic device is examined.
3. Using specialized tools, a lift loop mechanism is attached to the drop lock ring of the knee orthotic.
4. Adjustments are made to ensure the lift loop functions correctly.
5. The orthotic device is tested with the patient to confirm ease of use.

• Tools and Equipment: Orthotic adjustment tools and lift loop mechanisms.
• Anesthesia/Sedation: Typically, no anesthesia or sedation is required.

Duration

The procedure generally takes about 30 to 60 minutes.

Setting

This procedure is typically performed in an outpatient clinic or orthotic service center.

Personnel

• Orthotists or orthotic technicians with experience in knee joint modifications.
• Support staff such as medical assistants may be present to aid in the procedure.

Risks and Complications

• Common Risks: Minor discomfort or irritation at the site of adjustment.
• Rare Risks: Device malfunction or improper placement leading to reduced efficacy.

Benefits

• Expected benefits include easier manipulation of the knee joint lock, leading to greater independence and mobility.
• Benefits Realized: Most patients notice improved use of their orthotic device almost immediately.

Recovery

• Post-Procedure Care: The patient may need a short period of observation to ensure the new mechanism is functioning correctly.
• Expected Recovery Time: No extended recovery period is typically necessary.

Alternatives

• Other Treatment Options: More extensive orthotic modifications, physical therapy, or alternative assistive devices.
• Pros and Cons: Alternatives may offer greater customization but can be more invasive or time-consuming.
