Name of the Procedure:

Addition to Lower Extremity Fracture Orthosis, Drop Lock Knee Joint
Common Names: Drop Lock Knee Brace Adjustment, Knee Orthosis Augmentation
Technical/Medical Terms: L2182 HCPCS Procedure, Orthotic Knee Joint Modification

Summary

This procedure involves modifying a knee brace (orthosis) by adding a drop lock mechanism. This feature allows the knee joint to be locked or unlocked, providing either rigidity or flexibility depending on the patient’s needs.

Purpose

The primary goal is to support and stabilize the lower extremity following a fracture. The drop lock mechanism enhances the functionality of the brace, offering improved mobility, stability, and comfort.

Indications

• Recent or healing fractures in the lower extremity
• Conditions requiring controlled knee motion
• Need for both mobility enhancement and rigid support during recovery
• Post-surgical stabilization during rehabilitation

Preparation

• Patients should follow their healthcare provider's pre-procedure instructions.
• No specific fasting or medication adjustments are typically required.
• A thorough assessment of the patient's condition and the fitting of the current orthosis are necessary.

Procedure Description

1. The patient is evaluated to determine the appropriate modifications needed for their orthosis.
2. The orthotic technician or healthcare provider removes the existing knee joint if required.
3. The drop lock knee joint is installed and adjusted to fit the patient's anatomy and therapeutic needs.
4. The provider ensures that the lock mechanism functions correctly, providing both rigid and flexible settings as needed.
5. The patient is fitted with the modified brace and instructed on its use.

• Tools/Equipment: Orthotic tools, drop lock knee joint components, knee brace materials.
• Anesthesia/Sedation: Not applicable; the procedure is non-invasive.

Duration

The modification procedure typically takes about 30-45 minutes, including fitting and adjustment.

Setting

This procedure is usually performed in an outpatient clinic or an orthopedic provider’s office.

Personnel

• Orthotic technician
• Orthopedic physician or specialist
• Rehabilitation or physical therapist (for post-procedure training)

Risks and Complications

Common Risks:

• Minor discomfort during initial fitting
• Possible skin irritation Rare Risks:
• Improper fitting leading to inadequate support or discomfort
• Mechanical failure of the drop lock mechanism

Benefits

• Improved stability and support for healing fractures
• Enhanced mobility with the flexibility of locking and unlocking the knee joint
• Increased comfort during recovery

Recovery

• Patients can typically resume normal activities immediately, with adjustments as needed for comfort.
• Follow-up appointments may be required to ensure proper function and fit.
• Patients should adhere to instructions on the use of the orthosis and any prescribed physical therapy.

Alternatives

• Standard knee braces without a drop lock mechanism: May not offer as much flexibility.
• Surgical interventions: More invasive with longer recovery times.
• Functional bracing and physical therapy without orthotic devices: May be less effective for severe fractures or instability.

Patient Experience

During the procedure, the patient will likely experience minimal discomfort. After the procedure, they may feel an initial adjustment period as they get used to the modified brace. Pain management for associated injuries is typically addressed separately, and comfort measures include ensuring proper fit and function of the orthosis.
