Overcome chronic knee pain

and regain the independence, freedom and strength of your younger years

There’s still hope!

The good news is that we have decades of research and knowledge on knee pain and how to manage and overcome it.

Since the beginning of time, the brightest minds in history have dedicated their lives to helping people treat and manage their pain.

With the right strategies and habits, overcoming pain is possible.

And that’s what you’ll get today with our physiotherapist-led Back to 25 Rehab Program.

We partnered with Mathieu Sonier, a physiotherapist with 11 years of clinical experience.

He is going to show you exactly how you can recover from knee pain with several simple yet effective exercises. No equipment needed. You don’t even have to leave your house.

Knee Clinic courses are designed to specifically address the root-cause of age-related chronic knee pain and joint degeneration.

As we age, we lose muscle mass and function. We also experience changes in our neuro-motor system, such as reduced sensorimotor coordination and lower body strength and stability.

Weakened or improperly functioning muscles place increased stress on our joints and cartilage as we move around, subjecting them to increased wear and tear and causing structural joint problems and pain.

Knee Clinic uses the Neuromuscular Physical Therapy (NPT) approach

to progressively rebuild strength in key muscle groups connected to the knee, and retrain your neuromuscular system.

With improved muscle strength and better muscle activation and coordination, we relieve pressure on the knee joints.

This in turn relieves cartilage decay, increasing joint stability and functioning and reducing knee pain.

NPT is different from traditional physiotherapy.

It focuses on quality over quantity

enhancing muscle activation through functional and proprioceptive training, rather than simply increasing reps to become stronger.

This in turn relieves cartilage decay, increasing joint stability and functioning and reducing knee pain.

This training has been proven

to relieve pain, improve function and biomechanics in the knees, as well as even reverse cartilage decay, which is the root cause of pain in conditions like osteoarthritis.

With just 6-8 weeks of consistent and deliberate NPT training, you can improve your osteoarthritis pain and reclaim your freedom and independence.

Living pain-free is possible

Rehabilitation is a journey—a lifelong process.
And to be honest: it won’t be easy.

But on the day when you finally find yourself doing the things
you could only dream of before, everything will be worth it.

You have to be patient
and take it step by step…

  • Course 1: Salvage

    The very first step of knee rehab is to help you find relief from pain. To do that, we will start by rebuilding strength in your knees and retrain your neuromuscular system for better muscle activation and coordination.

  • Course 2: Stabilize

    The next step is to stabilize the joint ever further, and to create even more neuromuscular adaptations for a stronger and more stable knee.

    We’ll also work to improve your stability and balance overall, which will reduce the risk of falls and injury, and help you improve mobility and regain the confidence to move about freely and easily in your daily life.

  • Course 3: Strengthen

    Finally, with reduced pain and improved stability, we will build upon that foundation to enhance your muscle, bone and joint strength.

    We will prepare you to return to activities that you might have stopped doing because of your knee pain.

    These exercises will also help to slow down the progression of conditions like osteoarthritis, and help you get to a truly pain-free life. And done consistently, these exercises will also help you to live independently and remain mobile into your 80s or 90s.

    Don’t wait until your knees cross the line of no return, where you may have to rely on a wheelchair or walking aid to get around.

    The world was your oyster, full of opportunities and wonder.

    So many things to do, see and experience. You were only limited by the number of hours in a day.

    You could push your body to the limits, wake up the next morning like nothing happened. Any damage or illness would heal in a matter of days.

    It all boils down to your personal choice: keep moving forward or simply drift along.

    You decide.

    Frequently asked questions

    Knee Clinic is a physiotherapist-led rehab program designed to help people suffering from osteoarthritis and other age-related knee conditions to strengthen their knees and get relief from pain.

    Knee Clinic consists of three courses:

    • Knee Salvage, to kickstart your recovery;
    • Knee Stabilize, to establish a resilient foundation; and
    • Knee Strengthen, to empower lasting knee health.

    No equipment is needed for Knee Clinic programs. All you need is your body and a yoga or exercise mat for comfort.

    Each course consists of a set of exercises which take 10-15 minutes to complete. The exercises are split into 3 parts: warm up, physiotherapy, and cool down.

    You'll repeat the exercises over about 4-6 weeks, and progress to the next course when you're ready. It takes an average of 12-18 weeks to complete all three courses in the Knee Clinic program.

    We generally do not recommend people who have undergone knee surgery in the past 4-6 weeks to do the exercises in Knee Clinic programs. People with knee injuries that are in the acute inflammation stage should also avoid starting Knee Clinic until the inflammation stage has passed.

    Once you have recovered enough that you can walk without significant pain, you should be able to start work on Knee Clinic, beginning with the first course, Knee Salvage. However, please check with your physician or primary care provider, as your individual circumstances may vary.

    Knee Clinic is designed for people of all ages and experience levels to follow along at their own pace. Whether you are a first-timer or a seasoned athlete, Knee Clinic is for everyone who experiences knee pain and want to strengthen their knees and get relief.
