Knee orthosis (ko), double upright, thigh and calf, with adjustable flexion and extension joint (unicentric or polycentric), medial-lateral and rotation control, with or without varus/valgus adjustment, prefabricated, off-the-shelf
HCPCS code
Name of the Procedure:
Knee Orthosis (KO), Double Upright, Thigh and Calf, with Adjustable Flexion and Extension Joint (Unicentric or Polycentric), Medial-Lateral and Rotation Control, with or without Varus/Valgus Adjustment, Prefabricated, Off-the-Shelf (K0902)
Summary
The knee orthosis (KO) is a specially designed brace that supports the knee joint. It features adjustable joints that control the knee’s range of motion and provide stability. The brace can manage medial-lateral and rotational movements and can be adjusted for varus (inward) or valgus (outward) alignment. This prefabricated, off-the-shelf device is commonly used to assist with rehabilitation or to manage conditions affecting knee function.
Purpose
To provide structural support to the knee joint. To manage and correct knee instability, alignment issues, or restricted movement. To aid in rehabilitation following knee injuries or surgeries. To offer pain relief by minimizing undue stress on the knee joint.
Indications
Symptoms such as knee instability, pain, and limited range of motion. Conditions including ligament injuries (ACL, PCL, MCL, LCL), meniscus tear, arthritis, patellar subluxation, or post-operative knee stabilization. Patients requiring support for impaired knee function due to injury or chronic conditions.
Preparation
No special preparation such as fasting or medication adjustment is typically needed. An evaluation by a healthcare professional to determine the correct size and fit for the brace. Possible imaging tests like X-rays or MRI to assess the condition of the knee.
Procedure Description
- The healthcare provider assesses the patient and selects an appropriately sized knee orthosis.
- The brace is positioned on the leg, covering the thigh, knee, and calf.
- Adjustable straps are fastened to ensure a secure fit, providing necessary compression.
- The joints on the brace are adjusted to control the knee’s range of motion, limiting or promoting flexion and extension as required.
- Additional adjustments are made for medial-lateral stability and varus/valgus alignment correction, if necessary.
No anesthesia or sedation is needed as the procedure is non-invasive.
Duration
The fitting and adjustment process typically takes about 20 to 30 minutes.
Setting
The procedure is generally performed in an outpatient clinic, orthotic/prosthetic facility, or physical therapy center.
Personnel
Orthotist or prosthetist to fit and adjust the brace. Physical therapists may be involved in demonstrating exercises or educating the patient on using the orthosis. Healthcare providers such as doctors or nurse practitioners who diagnose and recommend the use of the brace.
Risks and Complications
Minor risks include skin irritation, bruising, or discomfort from improper fit. Rare complications might involve pressure sores or impaired blood circulation if the brace is too tight. Proper fitting and regular follow-up can manage and mitigate these risks.
Benefits
Improved stability and support for the knee joint. Enhanced mobility and reduced pain. Assists in faster recovery during rehabilitation. The patient can typically notice benefits within a few days, as knee function begins to improve with continued use.
Recovery
Instructions on how to wear and adjust the brace. Guidelines for exercising and using the knee orthosis during daily activities. Follow-up appointments to monitor progress and make adjustments if needed. Recovery time varies depending on the underlying condition and adherence to rehabilitation protocols.
Alternatives
Other treatment options include physical therapy, medication, surgical interventions, or different types of knee braces. Physical therapy can strengthen muscles and improve knee function, but may not provide immediate stability. Surgical options can offer a permanent solution but come with higher risks and longer recovery times. Alternative braces might be custom-made for more precise fit but are typically more expensive.
Patient Experience
The patient might feel some initial pressure as they adapt to the brace. Minor discomfort might occur but should decrease with time and proper adjustment. Effective pain management measures include taking recommended pain relievers and following up on any discomfort with the healthcare provider.
