Ottobock Waterproof Prosthetics and Orthotics

Dive into the world of Waterproof Solutions by Ottobock.

Say hello to new possibilities for your patients. These prosthetic and orthotic devices are specifically engineered to withstand the challenges of water, allowing for patients to participate in their favorite aquatic activities with ease and confidence.


Many individuals live, work, and play in environments that have water exposure. This may include a spring rain shower on the golf course or watching the kids play around the pool. However, recreational needs are just part of the functional picture.

The most important applications for waterproof components are at home or work. Cleaning the gutters at home, cleaning up a workshop, or handling a construction job are very practical examples of the need for a worry-free prosthesis.


In manufacturing, ingress protection (IP) describes the degree to which a device’s electronics are protected against dust, solids, and liquids such as water. The prosthetics industry uses the same designations to describe levels of waterproofness for microprocessor knees and feet.

C-Leg 4 and Genium have an IP 67 rating. These MPKs are safe to use in fresh water under the following conditions: submersion up to 1 meter for 30 minutes.

Genium X3 has an IP 68 rating and is also corrosion resistant. The X3 can be submerged in fresh, salt, and chlorinated water up to 3 meters for 1 hour.

It’s important to remember that the IP rating only refers to protection for the product’s electronics. Microprocessor knees have IP ratings, but mechanical knees do not. A fully waterproof knee or foot must have the ability to resist corrosion when immersed in fresh water, chlorinated water, or salt water. That’s the reason Ottobock uses the terms water resistant and waterproof. Ottobock water resistant knees protect the electronics against limited submersion but require maintenance for the mechanical parts. Ottobock waterproof knees protect the electronics and the mechanical working parts.


Each individual user is responsible for maintaining their prosthesis. Even waterproof knees benefit from regular care. When prosthetic components are exposed to corrosive elements such as chlorinated water or salt water, the components should be thoroughly rinsed with fresh water, drained of excess moisture, and then dried with a lint-free towel.

It is often helpful to pair a waterproof knee with a foot that can drain water through the pyramid or the foot shell. This makes maintenance easier for the user.
