Name of the Procedure:
Common Name(s): Knee brace, Knee orthosis
Technical/Medical Term: Knee orthosis, adjustable knee joints (unicentric or polycentric), positional orthosis, rigid support, prefabricated, off-the shelf (HCPCS Code: L1833)
Summary
A knee orthosis is a type of brace designed to provide support, stabilization, and proper alignment for the knee joint. This particular brace is prefabricated, off-the-shelf, and features adjustable joints to customize fit and function for the patient's needs. It is typically used for those recovering from knee injuries or surgeries and offers a rigid support for effective mobility and healing.
Purpose
The knee orthosis addresses various orthopedic conditions involving knee joint instability, alignment issues, or post-operative recovery. Its main goals are to provide stability, proper alignment, and to reduce pain during movement, allowing for a safer and more effective rehabilitation process.
Indications
- Knee ligament injuries (e.g., ACL, PCL, MCL, LCL tears)
- Post-surgical recovery (e.g., knee arthroscopy, ligament reconstruction)
- Osteoarthritis or other degenerative knee diseases
- General knee instability or hyperextension
- Patients who need additional support during physical therapy
Preparation
- No specific fasting or medication adjustments required.
- A thorough evaluation by a healthcare provider to determine the correct size and type of orthosis.
- Measurements of the knee and leg circumference may be needed.
Procedure Description
- Evaluation: The healthcare provider assesses the patient’s knee condition and measures the leg for appropriate brace fitting.
- Fitting: The prefabricated knee orthosis is selected and adjusted to fit the patient’s leg, ensuring the joints (unicentric or polycentric) are aligned with the knee.
- Education: The patient is educated on how to wear, adjust, and care for the orthosis.
- Trial Wear: The patient wears the orthosis under supervision to confirm comfort and effectiveness.
Tools and Equipment: Prefabricated knee orthosis, measuring tape, adjustment tools.
Anesthesia or Sedation: Not applicable.
Duration
The fitting and education procedure typically takes around 30 minutes to 1 hour.
Setting
Performed in outpatient clinics, orthotics and prosthetics centers, or rehabilitation facilities.
Personnel
- Orthotists or prosthetists
- Physical therapists or rehabilitation specialists
- Physicians or orthopedic specialists (for prescription and evaluation)
Risks and Complications
- Skin irritation or pressure sores
- Discomfort or improper fitting
- Limited range of movement if improperly adjusted
Benefits
- Immediate stabilization and support for the knee
- Enhanced mobility and reduced pain
- Promotes proper healing and joint alignment
Recovery
- Follow-up appointments may be needed to adjust the brace and monitor progress.
- Patients should gradually increase activity under medical supervision.
- Regular skin checks and brace adjustment to avoid discomfort.
Alternatives
- Custom-fitted orthoses for more personalized support
- Physical therapy alone for mild cases
- Surgical intervention for severe or non-responsive conditions
Pros: Custom-fitted orthoses offer more tailored support; physical therapy is non-invasive.
Cons: Custom-fitted orthoses can be more expensive; surgery involves more risks and longer recovery.
Patient Experience
- During Fitting: Mild discomfort from adjustments, similar to trying on a new, snug garment.
After the Procedure: Initial awareness of the brace; mild soreness as the body adjusts to new support.
Pain Management: Over-the-counter pain relief as necessary, proactive skin care to prevent irritation.
Comfort Measures: Properly fitted orthosis, regular follow-ups to make adjustments, and clear education on use and care.
