What are the main differences between Custom and Off-The-Shelf (OTS) braces?

The CTi Custom is hand-crafted to your exact leg size and shape. Photographs and measurements are taken of your leg and a custom sized frame is manufactured. There is also the option to have custom paint jobs on the CTi Custom, varying from changing the colour to fully personalised designs. (Custom colours are an extra cost).

The CTi Custom has two rigid lateral arms for further stability, because having your exact measurements allows us to manufacture a brace with a more intimate fit and a larger contact area to the leg.

The CTi OTS comes in a range of set frame sizes. The OTS can be adapted with different sizes of straps and padding which allow you to achieve the closest possible fit. Flexible subshells allow a customised fit.

The warranty options differ between the products and the different product parts.

What happens if my leg shape changes?

With the CTi OTS version of the brace there are varying thicknesses of condyle pads available. This allows you to adapt the brace to variations in knee width during the lifetime of the brace. In addition, the flexible subshells will conform to your leg shape as it changes.

The custom version is manufactured specifically to your  leg shape. Each CTi Custom comes with a 12-month fit guarantee. If your leg shape changes within the first 12 months so that the brace no longer fits correctly, we will re-measure and have a new brace made free of charge.

What is a PCL version of the brace?

For users with PCL instability, this version of the brace has additional supports to the thigh and calf to reduce movement of the shin backwards in relation

How do I clean my CTi?

You can remove the pads and straps to be cleaned. This should be done with mild, non-detergent soap and left to air dry. You should check the hinges for foreign objects after each use and remove anything found in the hinge. If you will be using the brace in salt water, be sure to rinse the brace and the straps with fresh water after each use to remove any salt or debris that might remain.

Can the CTi be used in water?

Yes, all CTi braces are non-corrosive and have been designed with water sports in mind. We recommend the use of an over sleeve when participating in water sports to insure that straps will remain firmly attached in high speed falls. If you will be using the brace in salt water, be sure to rinse the brace and the straps with clean water after each use to remove any salt or debris that might remain.

I ride MX - which brace is suitable?

Both the Custom and OTS can be used for Moto Cross. You will also need to order the MX kit, which contains a Patella Cup & a set of Gear Guards to provide extra protection for you and your bike.

How can I be fitted for a brace?

You can buy your CTi OTS knee brace online at www.ossurwebshop.co.uk where we have videos to help you measure for the right size and how to get the perfect fit. Alternatively, you can have your OTS or Custom fitted by a clinical professional at one of our partner clinics. If this is your first brace we recommend having it fitted by a clinical professional to ensure you’re wearing it correctly and you get the maximum protection you deserve from a CTi.

Can I wear it over clothes?

As the function of the CTI is to control movement at the knee joint the brace is designed to worn as close to bone/skin as possible. For this reason we recommend NOT wearing it over clothes. Although not ideal, undersleeves and tights offer a thin barrier if you are feeling any chaffing or irritation from the brace on your skin. Wetsuits can also be used under the brace if needed. Simply remove the padding and place the brace directly over the wetsuit – the thickness of the wetsuit will replace the padding and the brace should still fit correctly. The condyle pads which fit on the inside of the brace hinge can be altered for thickness, allowing you to wear thin underclothes or wetsuits if they need to.

How long will the brace last?

How long the brace will last depends on how it is used and how well it is maintained. You can remove the pads and straps to be cleaned. This should be done with mild, non-detergent soap and left to air dry. You should check the hinges for foreign objects after each use and remove anything found in the hinge.

For the CTi Custom there is a limited life-time manufacturer’s guarantee on the frame and six month guarantee on the soft good. The CTi OTS brace has a two year manufacturer guarantee on the frame and a six month guarantee on the soft goods.
