Key Findings
- 01Knee health is a critical factor influencing locomotion and mobility.
- 02Impaired knee function leads to biomechanical and physiological changes with significant public health and economic consequences.
- 03Knee health is a dynamic system involving structural integrity, neuromuscular control, biomechanics, and functional mobility.
Application
Design takeaway
Design products and systems that actively support or preserve knee health to ensure sustained user mobility and independence.
How to apply
When designing products for mobility, such as footwear, assistive devices, or even furniture, analyze the forces and movements involved and how they might affect the knee joint over extended periods of use.
Project actions
- 01When researching user needs, ask about any physical limitations or concerns related to joints.
- 02Consider how your design might affect the user's posture and gait, especially concerning the knees.

Strengths & Limitations
Strengths
- +Comprehensive synthesis of current knowledge.
- +Highlights the interconnectedness of various factors affecting mobility.
Limitations
The review is a synthesis of existing literature, not a primary experiment, so direct testing of specific design interventions based solely on this paper might be limited without further research.
Reliability & validity
The reliability of the findings in this review depends on the quality and consistency of the studies it synthesizes. Validity is enhanced by the broad scope of the review, covering multiple facets of knee health and mobility.
Think critically
How can design proactively address the decline in knee health and mobility, rather than merely reacting to existing conditions?
Design Principles
"Design for Longevity: Prioritize user well-being and functional independence by considering the long-term impact of design choices on physiological health, particularly joint integrity."
Designers and engineers must consider the long-term implications of product use on joint health. Products that place undue stress on the knees or fail to support proper biomechanics can lead to reduced mobility and increased health burdens for users over time.
What This Means for Your Design
Keeping your knees healthy is super important for being able to move around and do things on your own your whole life. If your knees aren't healthy, it can cause other problems and make life harder.

Paragraph starter
The healthspan is significantly influenced by the integrity of key joints, such as the knee. Research indicates that knee health is a primary determinant of mobility and functional independence, with impairments leading to biomechanical alterations and substantial public health challenges. Therefore, design interventions must consider the long-term physiological impact on users, prioritizing solutions that support or enhance knee function to ensure sustained mobility and quality of life throughout their lifespan.
