A custom knee refers to several different types of knee-related devices or procedures, all tailored to a specific individual. This contrasts with standard, "off-the-shelf" options.
Types of Custom Knees:
There are primarily two interpretations of "custom knee":
1. Custom Knee Implants (Prosthetics):
This refers to customized knee replacement implants. Unlike traditional knee replacements, which use prefabricated components, a custom knee prosthesis is designed using a 3D model created from an MRI scan of the patient's knee. Conformis is one example of a company that produces such implants. This individualized approach allows for:
- A more precise fit.
- Improved alignment.
- Potentially longer implant lifespan.
- Asymmetrical designs to address unique joint morphology (Mayo Clinic).

2. Custom Knee Braces:
These are orthopedic braces designed and manufactured to precisely fit an individual's leg. Unlike off-the-shelf braces, which are available in standard sizes, custom knee braces provide:
- Superior support and stability.
- Improved comfort and fit.
- Enhanced effectiveness in managing specific injuries or conditions like ligament instability or osteoarthritis.
- Lightweight materials for better comfort during wear.

Medicare Coding: It's important to note that both off-the-shelf and custom-fit knee braces are considered prefabricated braces for Medicare coding purposes (CMS). https://www.cms.gov/medicare-coverage-database/view/article.aspx?articleId=52465
