Aspen Ci Ligament Knee Brace

$840.00

The Aspen® Ci Knee is a rigid hinged brace for a knee that has lost its ligament support — after a cruciate ligament or meniscus injury, after surgery to repair one, or where the joint is unstable enough that it gives way.

A frame runs down both sides of the leg with a hinge at each side, and six numbered fasteners close in a set order so the brace ends up centred on the kneecap and stays there. The strap behind the calf is the one that matters most: it takes purchase over the calf muscle and is what stops the brace sliding down.

Both hinges accept stops that cap how far the knee may straighten or bend — extension at 0, 5, 15, 20 or 25 degrees, flexion at 0, 30, 45, 60, 75 or 90 — so the allowed range can be opened up as rehabilitation progresses.

Is this the right one for you?

Choose this if a ligament is torn or has been repaired — the cruciate ligaments inside the knee, or the ones at the sides.

Knee gives way or shifts? Bauerfeind GenuTrain S Pro Knee Brace adds hinges for side-to-side stability.

Prescribed a brace after surgery? Aspen ROM Knee Brace holds the knee still or limits how far it bends.

This is a medical-grade orthopaedic brace that incorporates rigid structural support. Braces and orthoses built with rigid components are usually covered under Canadian extended health benefit plans (e.g. Sun Life, Manulife, Canada Life, Blue Cross, Green Shield Canada) when accompanied by a valid prescription from your physician or nurse practitioner. It may also qualify as an eligible medical expense under the CRA's Medical Expense Tax Credit. We're happy to prepare an itemized estimate for your insurer — use Get an Insurance Estimate for this item, or add several to your cart and request one for everything at once. No charge, and it's not an order. Coverage details, annual limits, and prescription requirements vary by plan, so please confirm your specific benefits with your provider and keep your prescription and itemized receipt for your claim.

Aspen prints these steps; the range-of-motion stops should only be set by the clinician who prescribed the brace.

Open every fastener first by pressing the button on the side of each one.
Sitting down, bend the knee to about 30 degrees.
Hold the brace against the side of the leg so the centre of the hinge lines up with the centre of the kneecap.
Close the fasteners in the printed order: lower shin (1), upper rear thigh (2), lower thigh (3), rear calf (4), upper calf (5), front thigh (6).
Adjust straps 4 and 5, and 3 and 6, against each other so the hinge stays centred and the straps are snug but comfortable. The rear calf strap is what stops the brace migrating down the leg.
To take the brace off, press and release the fasteners; to put it back on, simply click them into place.
Straps that are too long can be cut to length: open the strap pad and the end of the binding strap, separate the hook and loop, trim, and re-attach the pad.
