Knee osteoarthritis (gonarthrosis) is the wear and tear of the joint cartilage in the knee and the most common form of osteoarthritis overall. Typical signs include morning start-up pain, stiffness after prolonged sitting, and pain when climbing stairs. And unfortunately, the reflex to protect the knee is also typical. That is exactly what leads you in the wrong direction. At BodyLab in Zurich Altstetten, we focus on what treatment guidelines recommend as the first choice: training and physiotherapy, built specifically around your findings.
Knee Osteoarthritis: Movement Doesn't Harm—It's the Cure
Cartilage has no blood supply of its own; it's nourished through loading and unloading, just like a sponge. If you protect it too much, you cut off its supply, lose muscle mass, and the same load hits the joint completely unfiltered—a downward spiral of less movement and more pain. Guided loading turns things around. That is why active training is positioned ahead of injections and surgeries in international guidelines. Let's be honest about the goal: we are not trying to reverse the osteoarthritis on your X-ray, but rather to ensure you have less pain in your daily life and can do more of what you love again.
How We Treat Your Knee Osteoarthritis
First, the assessment: strength, mobility, gait, load capacity, and your personal goals. Your tailored program is built on this foundation: physical therapy and manual therapy to restore mobility, strength building for your thighs and hips, combined with functional daily movements like climbing stairs and standing up. You will train directly in our clinic, guided through medical training therapy (MTT) on medically certified equipment, and supported by a home exercise plan that fits seamlessly into your routine. Osteopathy can also play its part, looking at the entire kinetic chain surrounding the knee—such as the hip, pelvis, and foot—if they are contributing to the stress on your joint.
Delay Your Joint Replacement or Prepare for Success
Conservative treatment and joint replacement are not mutually exclusive; they are simply two stages on the same path. As long as your knee functions well with training, there is every reason to postpone surgery. And if a joint replacement does become the right step: going into surgery strong means starting your recovery with the absolute best foundation. We support you every step of the way, both before the procedure and during your rehabilitation, in close coordination with your doctor.

Stay Strong, Stay Secure
A painful knee alters the way you walk, and moving less leads to a loss of strength and stability. Especially as we get older, a dual approach pays off: treating the knee while simultaneously reducing the risk of falls.

Who covers the cost? Let's talk investment in your future.

Cycling is the perfect starting point: maximum movement with minimal impact. Running is definitely not off the table either—a resilient knee can often handle much more than you think. It's all about the right dosage, and we are here to define that perfect balance with you.
