Knee Orthosis Procedure (L1845)

Name of the Procedure:

• Common Name: Knee Brace, Double Upright with Hinges
• Technical Terms: Knee Orthosis (KO), Unicentric/Polycentric Knee Brace

Summary

A knee orthosis is a medical device designed to support and stabilize the knee joint. It consists of double uprights, adjustable hinges for flexion and extension, and components to control medial-lateral rotation and varus/valgus alignment. It can be modified to fit the patient's specific anatomy.

Purpose

• Medical Conditions: Used to treat knee instability, ligament injuries, arthritis, post-surgical recovery, or conditions requiring medial-lateral and rotational control.
• Goals: To provide support, decrease pain, improve function, and prevent further injury.

Indications

• Symptoms/Conditions: Knee instability, ligament tears (ACL, PCL, MCL, LCL), post-operative support, osteoarthritis, and alignment issues.
• Criteria: Patients who require additional knee support due to injury, surgery, or degenerative conditions.

Preparation

• Instructions: Typically, no special preparation is required. However, patients should follow their physician's guidance.
• Assessments: A fitting session may be necessary to adjust the orthosis to the patient's measurements and specific needs.

Procedure Description

1. Evaluation: The healthcare provider assesses the knee condition and determines the need for a knee orthosis.
2. Measurements: Accurate measurements of the thigh, knee, and calf are taken to ensure proper fit.
3. Fitting: The prefabricated orthosis is trimmed, bent, and molded to fit the patient's leg perfectly.
4. Adjustment: Hinges are set for desired flexion and extension range, and straps are adjusted for snug fit without compromising blood flow.
5. Instruction: The patient is educated on how to wear, adjust, and maintain the orthosis.

Duration

The fitting procedure typically takes about 30-60 minutes.

Setting

This procedure is usually performed in an outpatient clinic, orthopedic office, or a specialized bracing center.

Personnel

• Orthopedic specialist
• Orthotist (a healthcare professional trained to design and fit braces)
• Medical assistant (optional)

Risks and Complications

• Common Risks: Skin irritation, pressure sores, discomfort, or improper fit.
• Rare Risks: Circulatory problems, allergic reactions to materials.
• Management: Regular follow-ups to adjust fit and address any discomfort or complications.

Benefits

• Expected Benefits: Enhanced knee stability, pain reduction, improved mobility, and faster recovery.
• Timeframe: Benefits are often realized soon after fitting, with full efficacy in a few days to weeks, depending on usage and condition.

Recovery

• Post-procedure Care: Wear the orthosis as prescribed by the healthcare provider, check for skin irritation or sores, and maintain hygiene.
• Recovery Time: Varies per individual condition; continuous use may be required for optimal outcomes.
• Restrictions: Avoid activities that may disrupt the fitting unless cleared by a healthcare provider.

Alternatives

• Other Options: Physical therapy, surgery, alternative bracing systems, or medication.
• Pros and Cons: Non-surgical options like physical therapy are less invasive but may require longer treatment time. Surgery can provide a more permanent solution but has higher risks and longer recovery.

Patient Experience

• During Procedure: Minimal discomfort expected during fitting.
• After Procedure: Initial wearing may feel unusual, but typically comfortable after adjustments. Follow-up visits help ensure continued comfort. Pain management and supportive measures will be provided to ensure the patient's comfort.
