Name of the Procedure

Addition to Knee Joint, Drop Lock (L2405)

• Common Names: Knee Drop Lock Addition
• Medical Term: Knee Orthosis with Drop Lock Mechanism

Summary

This procedure involves adding a drop lock mechanism to a knee joint orthosis. The drop lock is designed to secure the knee in an extended position, providing stability and aiding in movement control.

Purpose

The drop lock addition is used to address knee instability or weakness, particularly in conditions where the knee cannot remain extended without support. It aims to improve walking stability and prevent the knee from buckling.

Indications

• Knee instability due to muscle weakness or neurological conditions
• Patients with post-surgical knee rehabilitation needs
• Conditions such as quadriceps weakness, polio, or multiple sclerosis

Preparation

• A full assessment by a healthcare professional to determine the need for a knee orthosis
• Patients may need to provide a detailed medical history and undergo a physical examination
• No special preparation such as fasting is generally required

Procedure Description

1. Assessment: The healthcare professional evaluates the patient's knee stability and mobility.
2. Measurement: Precise measurements of the knee and leg are taken to ensure the proper fit of the orthosis.
3. Fabrication: The drop lock mechanism is custom-fitted to the patient's knee orthosis.
4. Fitting: The orthosis with the drop lock is placed on the patient's leg. Adjustments are made to ensure comfort and functionality.
5. Instruction: The patient is instructed on how to engage and disengage the drop lock, as well as proper use and care.

Duration

The total appointment, including assessment, fitting, and patient education, typically takes about 1-2 hours.

Setting

The procedure is typically performed in an outpatient clinic specializing in orthotic and prosthetic services.

Personnel

• Orthotist or Prosthetist
• Physical Therapist (optional for gait training)
• Medical Assistant (optional for support)

Risks and Complications

• Skin irritation or pressure sores from the orthosis
• Discomfort if the orthosis is not fitted properly
• Potential for mechanical failure of the drop lock

Benefits

• Improved knee stability during walking
• Prevention of knee buckling
• Enhanced mobility and confidence in movement

Recovery

• Patients typically experience immediate support and stability
• Instructions are given for daily wear and care
• Follow-up appointments may be scheduled to ensure proper fit and function
• Gradual acclimation to wearing the orthosis may be recommended

Alternatives

• Physical therapy and muscle strengthening exercises
• Use of other knee brace types without a drop lock
• Surgical options in severe cases of instability

Patient Experience

• The patient may feel an initial learning curve in using the drop lock mechanism.
• There could be some discomfort while adjusting to the orthosis, but this typically subsides.
• Pain management is rarely required, but over-the-counter pain relief can be used if needed.
