Knee osteoarthritis/gonarthrosis

Osteoarthritis is a common disease in modern western society. On the one hand, pressure on the joints increases the more a person weighs and, on the other hand, strain is placed on the cartilage for much longer than just 50 years ago as life expectancy keeps increasing. Furthermore, civilised human beings spend most of their time walking on flat, hard everyday floors, and most shoe manufacturers follow the philosophy that a shoe has to support and guide the foot, and must have a small heel. But our knees are not built for this type of stress. It puts massive improper strain on them, causing them to wear much faster (knee osteoarthritis).


‘Osteoarthritis is a degenerative joint disorder, caused primarily by discrepancies between the load and load capacity of various parts of the joints and tissue.’ [1]

The knee joints are especially susceptible to osteoarthritis, since they have to support most of the body weight. Knee osteoarthritis is usually associated with pain and increasingly limited freedom of movement in the knees. Pain makes it more difficult to get enough exercise.


Osteoarthritis can be caused by excessive weight and excessive strain, such as occurs during extreme sports or when performing heavy physical labour. Causes also include changes in the cartilage metabolism with advanced age, metabolic disturbances, congenital malformations and acquired joint deformities, for example due to inflammatory joint diseases or after an injury.

Many years of improper strain on the knee joint while walking is another possible cause . (See Fig. 1 and 2) The greater the impact while walking and the less precise the movement, the faster the cartilage will wear. The main cause of improper strain on the knee joint is the long periods of time we in industrialised western nations sit every day, something that nature did not intend. Sitting for hours leads to the progressive shortening of the hip flexors. As a result, the person is no longer able to achieve a physiologically correct gait with the upper body upright. This in turn leads to excessive strain on the neck and back musculature, incorrect knee position, and therefore to increased cartilage wear.

Long-term consequences – trapped in a vicious circle

Pain caused by osteoarthritis can lead to relieving postures, subsequently causing excessive strain on the joints and other body structures or leading to secondary disorders or secondary osteoarthritis. Furthermore, pain leads to a reduction in exercise and those who move less automatically put on more weight. This in turn has a negative effect on osteoarthritis complaints. Many affected by osteoarthritis are therefore caught in a downward spiral. The primary therapy objective is to escape this downward spiral.

Conventional therapy

Conservative treatment methods for knee osteoarthritis primarily consist of weight loss where necessary and of movement exercises, which are put together and taught by a physiotherapist. The aim of such exercises is to strengthen the muscles surrounding the joint. Additional treatment approaches include massage, the application of heat and cold, orthopaedic devices, and surgery when conservative treatment is not successful. The objective of conservative therapy is to maintain joint function and reduce pain.[1]

The kybun principle of operation – being proactive

The kyBounder and kyBoot are ideal for bringing more movement to everyday life and escaping the downward spiral of osteoarthritis – all without spending any additional time. Acute pain is alleviated quickly and, thanks to gentle loading of the knee joints, walking longer distances without pain is possible again.

The soft, elastic foam material acts as a ‘crumple zone’, effectively dampening impact on the joints during running and walking.

Movement becomes more comfortable again and knee complaints are reduced, usually after just a few minutes. Those who like to exercise frequently find it much easier to shed extra pounds, which in turn reduces strain on the joints. Nearly all customers affected by osteoarthritis report a reduction in pain since they started wearing the kyBoot.

At the outset with conventional shoes

It’s not only the cushioning effect that helps alleviate pain. When standing the soft, elastic supporting underlay, one automatically keeps moving very slightly. When standing and walking on soft, elastic materials, the core stability musculature has to make a major contribution in order to stabilise the joints. Strong core stability musculature results in a more upright posture, leading to more precise movements in the joints. Lack of exercise due to pain results in long-term muscle loss (amyotrophia). Signs of excessive strain in the knee joint can develop more quickly as a result. The ability to stabilise the joints under strain can be improved further through proprioceptive, sensorimotor and coordinative training on unstable surfaces. This counteracts the progression of osteoarthritis. Training the core stabilising musculature is easy to integrate into everyday life by wearing the kyBoot.

Attention! Short-term effects are often confused with lasting effects.

The adjustment processes in the body triggered by the kyBoot can take months or even years. Achieving lasting change is a protracted process.

Despite that, the effect of the soft, elastic material can also be felt quickly, for example in the relaxation of tense muscles and the alleviation of pressure points. These short-term effects must not be confused with the effects in the long run, since the long-term adjustment process cannot progress far enough in a week to be perceptible.

Short-term effects, on the other hand, can disappear again just as quickly as they came, or can even turn into complaints if you do not take the necessary breaks in the beginning.

It important to understand that an initial reaction and a reduction of the positive feeling in the first weeks with the kyBoot does not mean that the kyBoot is no longer working, but merely that the short-term sense of well-being is reduced!

Prevention with kybun

Everyone knows that the body shows signs of wear over time and that problems and complaints while walking and running are bound to occur eventually. Yet most people only start to consciously perceive their body as a fragile and transient structure once they experience problems. In most cases, however, it is already too late because irreversible damage such as cartilage wear has already occurred.

Therefore it is important to act before pain can already be felt or is increasing. The kyBounder and kyBoot help protect the joints and prevent osteoarthritis problems even in youth.

Folgende Anpassungen der Standarddurchführung des Intervall Walkings sind bei einer Kniegelenksarthrose wichtig: 

  1. Ziel: Schmerzlinderung
    - Falls schnelle Übungen Schmerzen verursachen oder als unangenhem empfunden werden, sollte man kleinere Schritte machen mit hoher Schrittfrequenz
  2. Fokus auf langsame Übungen, um Stabilität und Zusammenarbeit der Muskeln zu fördern
  3. Variante für langsame Übung: rückwärts gehen (Stabilität durch das Quergewölbe im Vorfuss gegeben)
  4. bei Fortgeschrittenen: Abwärtsgehen (vorwärts)
     - hohe Anforderungen an Stabilisierung der Knie

Application tips

Everyday/leisure: Walk with the kyBoot or use the kyBounder as much as possible. Watch for fatigue > breaks

Job: Sit as little as possible. Alternate sitting and standing in the beginning, and take along replacement shoes to change into

Precise movements are essential in case of knee osteoarthritis. Be sure to move in a precise manner and take breaks in case of fatigue or weakness.

Contact a kybun dealer you trust if you have further questions, feel insecure or if there is no alleviation of pain when using the kyBoot even though you are following the tips.

Opinions/customer testimonials

I am so glad that we discovered the kyBoot in a medical supply shop while travelling in Switzerland. I bought my first pair there about three years ago. Before that, I had already been wearing MBT shoes quite often. I began searching for a place to buy kyBoot shoes in Germany due to an advancing case of varus gonarthrosis and increasing knee problems, and now I have finally found your online shop! I am a big fan of wearing these shoes because they relieve the pressure on my kneecaps. I wear them everywhere – at home, in the office, in my spare time... The unparalleled level of comfort, the shock-absorbing soles and the stylish design mean that kyBoot shoes are irreplaceable in my daily life!
Vor acht Jahren wurde ich (damals 42 J.) mit der Diagnose Kniearthrose vierten Grades konfrontiert. Merkwürdig - ich ernähre mich gesund und bin normalgewichtig. Als Krankenschwester muss ich sehr viel laufen und bin auf die Funktion meiner Beine angewiesen. In den ersten Jahren hatte ich lediglich Schmerzen beim abwärts gehen. Die Schmerzen nahmen zu, wenn ich viel auf den Beinen war. In meinem Beruf waren das über acht Stunden, manchmal ohne Pause. Gelegentlich nahm ich Schmerzmedikamente. Doch irgendwann wurde der Leidensdruck so groß, dass ich ein Knie operieren ließ. Zunächst meinte ich, von dem Eingriff zu profitieren.  Doch durch die einseitige Belastung direkt nach der OP, verschlechterte sich das andere Knie. Als wenn es so sein sollte, wurde ich vor der zweiten geplanten OP mit dem Kyboot konfrontiert. In einer Boutique bekam ich beiläufig die Beratung einer Kundin mit, und ich hörte interessiert zu. Der Verkäufer empfahl auch mir, den Schuh nur mal kurz zu probieren. Etwas skeptisch folgte ich seinem Rat. Die ersten Schritte waren: Wow super bequem! So einen Tragekomfort hatte ich noch nie erlebt. Und gut sahen sie auch noch aus. Ich muss dazu sagen, dass ich keine Trägerin von "Gesundheitsschuhen" war. Trotz der Knieprobleme war ich zu eitel. Also der Kyboot war unfassbar bequem und cool, aber 260.- Euro.... - puh! Meine mich begleitende Freundin redete mir zu: bei meinem Job , und mit den Knieproblemen brauche ich die Schuhe! Und ich habe die Investition nicht bereut. Den ganzen Tag über bin ich nun fast schmerzfrei auf den Beinen - ohne Schmerzmittel. Die OP habe ich vorerst storniert. Natürlich ersetzen die Schuhe nicht den Knorpel. Die Pufferzone fehlt nach wie vor. Bei Belastungen habe ich nach wie vor Schmerzen und komme nicht in die Knie. Aber ich kann meinen Beruf weitestgehend schmerzfrei ausüben. Und das gibt mir Lebensqualität. Ich werde häufig auf die Schuhe angesprochen. Zum Einen sind sie Blickfang in ansprechender Farbe. Zum Anderen wird gesagt "Es sieht so aus, als würdest Du auf Wolken gehen" - so "leichtfüßig". Und genau so läuft es sich auch.
Two years ago I had osteoarthritis and my knee was so hurt. I couldn't even walk but after I put the kyBoot shoes on it was like a miracle, I'mable to walk ride away. It was amazing, It was really amazing.
At 66 years old, I have had two hip replacements, a right knee replacement, and have undergone two major back operations. My knees had always been swollen, but once I tried kyBoot, they became normal again after two days. Now I can walk for hours without limping. I feel truly alive again.
In our job, we're out and about all day. I walk about on bumpy paddocks and have arthritic knees which leave me in constant pain. The kyBoot replaces the cushioning which I lack in my knees due to the arthrosis. That soothes the pain.
I have arthritis in one knee, and these shoes make an incredible difference. When I walk on hard surfaces for a long time wearing regular shoes, I feel pain after just ten minutes.
Er ist wirklich gut, weil ich Arthrose im rechten Knie habe. Ich kann so einfach viel besser laufen, völlig problemlos.  Video ansehen
