Knee osteoarthritis unloader orthosis
An overview of knee orthoses that aim to redistribute load in order to relieve the overloaded area of the knee joint.
What is an unloader knee orthosis?
An unloader (load-reducing) knee orthosis is a type of orthosis that aims to reduce pressure on the overloaded part of the joint in knee osteoarthritis. Osteoarthritis usually affects the inner or outer compartment of the knee more; unloader orthoses are intended to apply a slight corrective force to the knee alignment in order to relieve the load on that compartment.
These orthoses may be considered as a supportive part of the treatment plan together with exercise, lifestyle adjustments and other approaches the physician considers appropriate. Suitability and the choice of type are determined only through a physician's assessment.
How does it work?
Unloader orthoses work on the three-point pressure principle. With support taken from the thigh and calf, the knee is gently guided away from the compartment where the pain is. The aim is for the load to be distributed more evenly within the joint and for the overloaded area to be relieved.
- The aim of reducing pressure in the overloaded joint compartment
- Supporting knee alignment
- Contributing to comfort and confidence in movement during daily activities
Key features
The features below are for general information; which design is appropriate is determined according to the person's condition and the physician's assessment.
Load redistribution
A slight corrective force applied to the knee alignment aims to reduce pressure in the overloaded compartment.
Adjustable support
Many designs are intended to allow the level of support to be adjusted individually.
Hinged structure
Side hinges aim to contribute to lateral stability while supporting the natural movement of the knee.
Everyday use
Slim and lightweight design options aim to make it easier to wear under clothing and throughout the day.
Different design approaches
Unloader knee orthoses vary according to different levels of support and intended uses. The general groups below are examples; the choice is made by the physician.
Rigid-frame design
Designs focused on active use that aim to provide more pronounced support with a rigid frame and hinges.
Active lifestyle design
Designs that take durability into account for outdoor and physical activities and aim to contribute to confidence in movement.
Everyday comfort design
Designs that prioritize lightness and comfort for long periods of use during the day.
Light support design
Designs with a more flexible and slim structure that aim to provide a light level of support.
Who may it be suitable for?
Unloader knee orthoses are usually considered when knee osteoarthritis predominantly affects one compartment and the pain makes daily activities difficult. The aim is to contribute to supporting the person's mobility and quality of daily life.
- Situations where pain is concentrated in a particular joint compartment
- A need for support in walking and daily activities
- Suitability and the choice of design are determined through a physician's assessment
The orthosis fitting process
Physician's Assessment
The process begins with a specialist physician's assessment and a prescription/medical report.
Measurement and Planning
The condition of the knee and the affected compartment are assessed; the appropriate type of orthosis and the service plan are determined.
Fitting and Adaptation
The orthosis is fitted; the level of support and adjustments are set individually.
Follow-up
Training in use is provided; follow-up is arranged for check-ups and adjustments when necessary.
Frequently asked questions
Does an unloader knee orthosis relieve pain?
Orthoses are a supportive part of the treatment plan; the aim is to relieve the overloaded area and contribute to comfort in daily activities. Results vary from person to person and are determined through a physician's assessment.
Should I wear the orthosis all day?
The duration and manner of use are determined by the physician according to the person's condition. Some people use it only during certain activities, while others may benefit from longer use.
Should I exercise?
Exercise and movement play an important role in managing knee osteoarthritis. An orthosis does not replace an appropriate exercise program; the program should be planned under the guidance of a physician and physiotherapist.
