Name of the Procedure:

Knee Orthosis, Adjustable Knee Joints (Unicentric or Polycentric), Positional Orthosis, Rigid Support, Prefabricated

Summary

This procedure involves customizing a prefabricated knee orthosis, a type of support brace, to fit a specific patient. The orthosis is adjustable, allowing for precise positioning of the knee and providing rigid support. An expert will trim, mold, and assemble the orthosis to ensure an optimal fit for the patient.

Purpose

The knee orthosis is designed to manage conditions such as knee instability, injury recovery, postoperative care, and degenerative joint disorders. The goal is to provide support, limit harmful movements, and promote healing or stable function of the knee joint.

Indications

• Knee instability or weakness
• Ligament injuries (e.g., ACL, PCL)
• Post-operative support following knee surgery
• Degenerative joint disorders like osteoarthritis
• Conditions requiring positional control of the knee

Preparation

• No specific preparation or fasting is required.
• Physical examination of the knee to assess fit and requirements.
• Possible imaging tests (e.g., X-rays) to guide fitting.

Procedure Description

1. The healthcare provider assesses the patient's knee.
2. The prefabricated orthosis is selected based on initial measurements and needs.
3. The orthosis is trimmed, bent, and molded to fit the patient's knee.
4. Adjustable unicentric or polycentric knee joints are positioned to allow controlled movement.
5. The orthosis is secured and fine-tuned to ensure comfort and efficacy.
6. The patient is instructed on how to wear and adjust the orthosis.

Tools: Prefabricated knee orthosis, measuring tape, scissors, molding tools.

Duration

The customization process typically takes about 30 minutes to 1 hour.

Setting

This procedure is usually performed in a clinical setting, such as a doctor's office, orthopedic clinic, or outpatient rehabilitation center.

Personnel

• Orthotist or specialist in orthotic devices
• Nurse or assistant

Risks and Complications

• Skin irritation or pressure sores
• Discomfort or improper fit requiring adjustments
• Limited mobility if the orthosis is not correctly adjusted
• Rare risk of allergic reaction to materials

Benefits

• Enhanced knee support and stability
• Reduced pain and discomfort
• Improved recovery from injuries or surgery
• Better alignment and reduced risk of further injury

Recovery

• Follow instructions on how to use and care for the orthosis.
• Avoid activities that may compromise the knee's stability as advised.
• Attend follow-up appointments to adjust the orthosis as needed.
• Full recovery or improvement may vary; it could take several weeks to months depending on the condition treated.

Alternatives

• Non-custom braces or sleeves, which may not provide as precise support.
• Physical therapy to strengthen the knee without mechanical support.
• Surgical options, depending on the severity of the knee condition. Pros and cons vary depending on the individual patient's condition and needs.

Patient Experience

During the fitting, the patient may feel slight pressure but should not experience significant discomfort. After the orthosis is in place, there might be a period of adjustment as the patient gets used to the support. Pain relief should be noticeable, and any discomfort due to the fit should be addressed by follow-up adjustments.
