medi M.4s PCL Dynamic Knee Brace

$948.00

The M.4s® PCL dynamic is a rigid four-point knee brace built for one job: treating the posterior cruciate ligament, the ligament that stops the shin bone sliding backwards under the thigh bone.

It is for non-surgical treatment after an injury to the posterior cruciate ligament, and for treatment after that ligament has been reconstructed.

A winged protection pad shaped to the shin presses forward on the tibia and holds it in the desired position. An integrated tensioning dial sets how much force the pad applies, and indicators on the side guide bars give a reference for its position; medi's own instructions have you turn the dial until the bony bump at the top of the shin sits level with the matching bump on the other leg. A rigid frame steadies the sides of the knee, the physioglide hinge follows its rolling and gliding movement, and wedges limit extension from 0 to 45 degrees and flexion from 0 to 90. Made as a left or a right.

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.

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.

Hand wash only, in lukewarm water (about 30°C/86°F) with a mild detergent
Close all hook-and-loop (velcro) fasteners, straps, and zippers before washing to protect the fabric
Do not use fabric softener, bleach, or harsh chemicals; do not dry clean
Remove and clean any removable pads or cushions separately with water or mild soap
Air dry fully -- do not tumble dry, use a hair dryer, or dry in direct sunlight
Apply skin creams or lotions after removing the support in the evening, not right before putting it on, since they can affect the material's properties

medi publishes these steps for putting the brace on. The tibia support is set up by a fitter first; ask to be shown once before doing it alone.

Open all the straps and pull them through the strap eyes, folding each end back on itself so the hook-and-loop does not catch on clothing.
Pull the knob out of the tibia support until it clicks, then draw the support back as far as it goes.
Bend the leg to about 70 degrees and put the brace on, so the centres of the hinges sit at the top edge of the kneecap and slightly behind the side centre line of the leg.
Fasten thigh strap number 3 and pull it tight, without letting the brace sit too far forward.
Turn the knob back in until it clicks, then turn the wheel until the bony bump at the top of the shin is level with the same bump on the other leg.
If the brace is being worn purely for stability, fasten the tibia strap last of all.
Move the knee gently a few times, check the position again and correct it if needed.
