Today's KNOWLEDGE Share

Carbon fiber composite is a lightweight material commonly used in a running blade. The blade is often embedded directly into the socket or fixed below the socket within lower-limb prostheses.

Athletes with unilateral transtibial amputations are prescribed C- or J-shaped running blades with a manufacturer-recommended stiffness category based on body mass and activity level, and height based on unaffected leg and residual limb length.

C-shaped running blades attach distal to the socket and are recommended for distance running (e.g. 10 km, half marathon, and marathon) and J-shaped running blades attach posterior to the socket and are recommended for sprinting (e.g. 100 m, 200 m, and 400 m).

C- shaped running blade is more effective at storing and releasing energy over time which helps you to run more efficiently and for longer periods of time.

J - shaped running blade allows for a quick return of energy helping you to achieve higher speeds.

Running blade height is set based on the athlete’s contralateral unaffected leg length, stride kinematics, and their prosthetist’s and personal preference.

The height of a C-shaped running blade is adjusted by shortening or lengthening the pylon that connects the running blade to the socket, while the height of a J-shaped running blade is adjusted by changing its mounting position posterior to the socket.

Composites are gaining popularity in modern-day orthopaedics and are used in orthotic and prosthetic manufacturing. According to Stratview Research, the market for orthopaedic composites will reach USD 286 million in 2024.
