The knee support thatstrengthens, not just supports.

The Kinetexx Knee Muscle Exerciser uses memory-retentive resistance springs to work the muscles around your knee as you move. It's built for ACL, MCL, PCL, patella, quad and hamstring injuries, and for osteoarthritis, designed to rehabilitate, protect, support and strengthen. Recovering from injury, training in the gym, or walking the dog: every step builds strength.

This is what makes Kinetexx different.

Inside every Kinetexx sit two memory-retentive resistance springs. They bend with your knee, gently loading the muscles around the joint with every single movement.

Memory-retentiveHowever hard you exercise or walk, the springs return to shape, every time.
Works both waysResists as you bend, assists as you straighten. The muscles do the work, the spring makes the work count.

How it works

Most knee supports hold your knee still. This one makes it stronger.

A compression sleeve squeezes the joint. Kinetexx works the muscles around it. That is a different job, and it is the reason this is not like anything you have already tried.

01 · Wear it

Pull it on like any support

Comfortable compression fit around the knee. No gym, no programme, no extra effort. Choose the spring level that matches where you are.

02 · Move

The springs work with every step

As your knee bends and straightens, the memory-retentive resistance springs gently load the muscles around the joint, the same muscles your physio tells you to strengthen.

03 · Get stronger

Strength builds during real life

The walk to work, the training session, the Sunday morning stroll. The strengthening happens while you live your life, not just in the physio room.

Compresses.

Warmth, compression and a feeling of support. Nothing works the muscle. Take it off and nothing has changed.

Kinetexx

Strengthens.

Resistance springs actively load the muscles around the knee during movement, so the support is building the strength your knee needs to protect itself.

What does it support?

One support, for the parts of the knee that take the strain.

Many knee conditions place increased demands on the muscles surrounding the joint. Building strength in the quadriceps and hamstrings can help improve stability, confidence and everyday movement.

Three resistance levels. One journey.

Progress at your own pace, from first steps to full strength.

Every Kinetexx comes with three interchangeable spring levels. They are not a specification detail. They are your route back.

The three Kinetexx resistance springs: white 2 x 3.5kg for recovery, yellow 2 x 5.0kg for strength, black 2 x 7.5kg for performance, each supplied as a pair White · Yellow · Black · supplied in pairs
White spring · 2x3.5kg

Begin

The gentlest resistance, for light exercise. For early recovery, getting moving again, and building the habit of movement without overloading the joint.

Stage 1 · Early recovery
Yellow spring · 2x5.0kg

Build

For moderate exercise. More resistance as the muscles respond, for daily wear, longer walks and a knee that is learning to trust itself again.

Stage 2 · Building strength
Black spring · 2x7.5kg

Perform

The strongest resistance. For training, sport and full activity, keeping the muscles around the knee working so you can stop second-guessing every step.

Stage 3 · Full activity
Nothing to lose

Try the one support that is actually trying to fix the problem.

Who it is for

Made for your knee, at every stage of life.

For osteoarthritis, everyday knee pain, and recovery after injury or surgery.

Kinetexx works the muscles around the knee so the joint is supported by strength, not simply held still. Whether you are coming back from an injury or keeping moving through the years, it meets you where you are.

Freedom, at any age

Life does not stop, and neither should you. As we get older the muscles around the knee weaken and the joint stiffens, and that is when a walk starts to feel like hard work. Kinetexx works those muscles with every step, so movement stays comfortable and your independence stays yours.

1 in 5people over 45 in the UK live with knee osteoarthritis. For most of them, staying active is the single most effective thing they can do.
  • Movement is medicine. For an arthritic or ageing knee, gentle exercise is the treatment doctors recommend first, ahead of painkillers. Keeping the joint moving eases stiffness and helps you stay mobile for longer.
  • Strong muscles protect the joint. The muscles around the knee are its shock absorbers. Working them, which is exactly what the springs are for, takes load off the joint and eases everyday aches.
  • It is never too late to start. Strength and mobility respond to gentle, progressive resistance at any age, in your sixties, seventies and beyond, not just in your twenties.
Recovery & rehabilitation

Back to full strength

Recovering from knee replacement surgery, a knee injury, or everyday osteoarthritis. Follow the guidelines of your physiotherapist or occupational therapist, and let gentle progressive resistance work the muscles that protect and stabilise the joint, so your knee feels steady and strong again.

Keep doing what you love

Managing osteoarthritis, easing stiffness, or simply staying mobile and independent as the years go on. Gentle, guided resistance keeps the muscles working, because for a knee, movement is medicine.
