Ergonomic assessment and gait analysis of a knee joint model with an active spring-reinforced centrally-rollable knee bypass support system

Musculoskeletal issues can lead to severe immobility problems when not identified and addressed early. An ergonomic assessment and gait analysis of a novel knee joint model featuring an innovative active spring-reinforced centrally-rollable knee bypass support system was conducted in this work. The study employed computer simulations using human knee joint models integrated with the proposed knee support system. Gait parameters, joint angles, and muscle activations were assessed to evaluate the system’s effects on knee joint stability, impact forces, and gait mechanics during various activities. The knee support system notably improved knee joint alignment, lessened joint forces, and optimized muscle activation patterns. The knee bypass support system facilitated a natural knee roll during walking and running, ultimately enhancing gait efficiency and reducing joint stress. The study’s findings showcase improved biomechanics, which hold promising implications for injury prevention, rehabilitation, and overall performance enhancement. With the support system, dynamic changes in tendon forces during activity enhanced the knee joint stability and coordination, which will improve performance and injury prevention. Balance of forces during different activities also encompassed the joint stability. The knee support system demonstrates its potential to address musculoskeletal issues by enhancing knee joint stability and optimizing gait mechanics. This innovation could significantly contribute to minimizing immobility concerns and improving individuals’ quality of life.
