A sports knee joint has to withstand the high loads that develop and act on the prosthesis while running. The familiar, patented principle of rotation hydraulics is used in a modified form in the 3S80 Sport as well. The joint is also equipped with a manual lock. Compact and robust, the 3S80 Sport is optimised for any type of running.
The lower leg of the prosthesis swings through freely to an angle of about 60° in the flexion direction. Even at high stride rates, a smooth extension stop is ensured by extension damping applied along the entire extension movement, which increases significantly shortly before reaching the end position. Flexion and extension damping can be adjusted separately and individually.

Product Description
Ottobock 3S80 Sports Running Prosthetic Knee Joint
High-Performance Sports Knee for Dynamic Running & Athletics
The Ottobock 3S80 Sports Running Prosthetic Knee Joint is a specialized mechanical knee joint engineered specifically for running, sprinting, and athletic activities in above-knee (AK) and transfemoral amputees. Purpose-built for sports, the 3S80 is designed to withstand high loads, rapid cadence changes, and repeated impact forces, making it an ideal solution for amputee athletes and highly active users focused on performance rather than everyday walking.
Unlike conventional daily-use prosthetic knees, the 3S80 Sports Knee is optimized for dynamic motion and high-speed biomechanics. Its robust mechanical design supports secure stance stability during loading and enables fast, responsive swing dynamics required for running. The knee works seamlessly with carbon fiber running blades, allowing efficient energy transfer, smoother stride cycles, and improved rhythm during sprinting and endurance running.
Built with exceptional strength and durability, the Ottobock 3S80 can tolerate intense athletic stress while maintaining consistent performance. The knee’s mechanical simplicity ensures reliability, low maintenance, and predictable behavior, which are critical during competitive sports and high-impact training. The design prioritizes safety and performance, enabling athletes to accelerate, decelerate, and maintain control with confidence.
At Credence Prosthetic India, the Ottobock 3S80 Sports Running Knee is fitted using a sports-specific prosthetic protocol. This includes athlete assessment, dynamic alignment, integration with appropriate running blades, and activity-focused gait and performance training. Credence’s experienced prosthetists understand that sports prosthetics require precision tuning, load testing, and performance optimization, not just standard alignment.
As one of India’s leading advanced prosthetic clinics, Credence Prosthetic India supports athletes and high-activity amputees with specialized sports prosthetic solutions, helping users return to running, competition, and active lifestyles. When professionally fitted and trained, the Ottobock 3S80 Sports Running Prosthetic Knee Joint becomes a powerful tool for speed, confidence, and athletic independence.
