Take a new path – put a stop to osteoarthritis of the knee

Arthrosis is a widespread disease, with estimates indicating that more than 12 million people in Germany are affected by this joint disease. This group includes young and athletic people, too.

Arthrosis most often develops in the knee. The diagnosis can make those affected feel uncertain. Many fear that they will always have knee pain from now on and that they will need to take analgesics (pain medication) to be able to move. They wonder how long they will still be able to pursue their hobbies or climb the stairs, and at what point they may no longer be able to do anything without a prosthetic knee joint. Isn’t there any other way out of pain besides medication, no way to avoid or delay an operation?

Yes, there is! Put a stop to arthrosis. These days, there are good options for living an active life with arthrosis. In many cases, an orthosis can help reduce the pain – and help you regain your quality of life. Thanks to the appropriate orthosis, surgery can often be avoided. This website will tell you what you need to know about osteoarthritis of the knee. You will also find tips and information that will help you live your life with this disease on your own terms.

Cuadro clínico

Cuadro clínico de la gonartrosis

La artrosis de rodilla (gonartrosis en el lenguaje especializado) es una enfermedad que provoca el desgaste de la articulación de la rodilla. No tiene cura y origina alteraciones progresivas en la rodilla. En la fase inicial de la artrosis, no se produce dolor, o solo de forma aislada, ni limitaciones de la movilidad. A medida que la gonartrosis avanza, los dolores y las molestias pueden aumentar. La mayor parte de las personas desarrolla a la largo de la vida artrosis como consecuencia de un desgaste. Factores de riesgo como, por ejemplo, el sobrepeso, una desalineación articular, la falta de actividad física, la sobrecarga y la carga inadecuada de las articulaciones en algunos deportes o lesiones aceleran el desgaste de las articulaciones y pueden favorecer la aparición de una artrosis incluso en personas jóvenes.

Arthrosis changes the joint

Because it’s a degenerative joint disease, osteoarthritis of the knee typically starts with signs of degeneration and/or minimal damage in the joint cartilage. As time passes, the cartilage surface becomes rough and uneven. The joint no longer moves smoothly. It snags and grinds. Increasing friction leads to painful inflammation in the knee, and fluid is effused into the joint capsule. In this condition, also referred to as activated arthrosis, there is constant pain. In the advanced stage of arthrosis, cartilage damage increases and all the tissue involved in the joint is affected. The bones form spurs (osteophytes) to stabilise the joint but cause ankylosis, or stiffening, in the process. Knee pain occurs at increasingly shorter intervals and becomes more severe over time.

Osteoarthritis of the knee is classified into four degrees of severity:

  1. Arthrosis severity
    The joint cartilage has invisible signs of degeneration. It’s less elastic than healthy cartilage and can’t recover well after being subjected to strain. Initial knee pain may occur under high strain.

  2. Arthrosis severity
    The cartilage tissue becomes thinner. The cartilage surface becomes rough and uneven. The bones form initial spurs (osteophytes). The knee’s ability to bear weight is decreased. At this stage of arthrosis, the disease progression can be effectively slowed by exercises, weight loss and medical devices such as orthoses.

  3. Arthrosis severity
    The cartilage has partly disappeared so that the bones begin to rub against each other in some places. X-rays show pronounced bone spurs and narrowing of the joint space. At this advanced stage, arthrosis causes considerable restrictions of movement and knee pain.

  4. Arthrosis severity
    The joint space has narrowed considerably and the joint cartilage has almost completely disappeared. The bones are often damaged. The joint is deformed and often inflamed. In this final stage, joint replacement surgery – that is, a prosthetic knee joint – may be the best solution.

The vicious circle of arthrosis

Patients with osteoarthritis of the knee frequently get caught in a vicious circle:
In order to relieve the pain in their knee, the affected person exercises less and often adopts a certain posture to avoid discomfort. However, restricting their movement only provides short-term relief from pain. In the long run, a lack of exercise accelerates cartilage wear and increases pain in the knee. The affected person rests their knee even more often instead of exercising it, and the vicious circle closes.
Furthermore, the unnatural posture they take to avoid discomfort also puts excessive strain on other joints such as the hips, which can cause permanent damage.

Initial symptoms of osteoarthritis of the knee

The sooner osteoarthritis of the knee is diagnosed and actively addressed, the better the chances of getting knee pain under control, maintaining joint mobility for a long time to come and slowing down the progressive changes in the knee joint.
If you experience the following symptoms in your knee on a recurring basis, you should have it examined by an orthopaedist:

  • Knee pain after rest (start-up pain)

  • Knee pain after unusual exertion

  • Knee pain during certain movements

  • Knee stiffness

  • Grinding and cracking in the knee joint

  • Swelling and inflammation in the knee

Diagnosis and therapy

Diagnosis and therapy for osteoarthritis of the knee

If you have knee pain or limited knee function, you should have it examined by an orthopaedist.

Diagnosing osteoarthritis of the knee

When talking to the doctor, you should give a detailed description of your knee problems and answer the physician’s questions precisely. In addition to the knee disorder, other health information such as arthroses in other joints, injuries, infections or chronic diseases may also be relevant to knee pain. During the examination, the physician will look at the knee and check its functions. They will then take an X-ray to see if any visible changes have already developed in the joint. In some cases, further examinations will be necessary to arrive at a diagnosis. Depending on the case, these include, for example, examinations of the blood or the joint fluid as well as other imaging procedures.

Tratamiento de la gonartrosis

Se distingue entre tres métodos de tratamiento básicos de la gonartrosis: el tratamiento conservador (no invasivo), el tratamiento invasivo con conservación de la articulación y el tratamiento invasivo con reemplazo de la articulación. Se denomina invasivos a los tratamientos en los que el médico efectúa cambios en la articulación de la rodilla.

Aliviar el dolor

Las órtesis alivian el dolor de rodilla

Las órtesis de rodilla o las órtesis de pierna y pie, como la Agilium Freestep, descargan de forma específica las zonas de la articulación de rodilla con dolor y pueden aliviar de forma duradera el dolor. Estudios realizados lo demuestran. En muchos casos, el uso de órtesis cuando se sufre de gonartrosis permite dejar de tomar analgésicos o reducir la dosis. Los efectos secundarios de los medicamentos se evitan o se reducen de un modo eficaz. Las órtesis de rodilla o las órtesis de pierna y pie permiten a los pacientes con gonartrosis un movimiento prácticamente indoloro, así como practicar deporte. De este modo es posible romper el círculo vicioso de dolor, falta de actividad física y empeoramiento progresivo de la artrosis.

Most of my patients are very satisfied with the new orthosis. More than half of them have been able to avoid surgery so far.

Activo contra la artrosis

Activo contra la artrosis

La gonartrosis no tiene cura, pero usted puede aliviar de modo eficaz el dolor y las molestias y, así, mejorar su calidad de vida si contrarresta de forma activa la artrosis con una alimentación saludable y movimiento adaptado.


Su menú debe constar, sobre todo, de frutas y verduras, ensalada, aceites vegetales, nueces y semillas. Los pescados como la caballa, el salmón y el arenque son ricos en nutrientes y en ácidos grasos omega-3 que tienen propiedades antiinflamatorias. Por ese motivo, este pescado saludable puede consumirse dos veces por semana. Algunas especias no solo mejoran el sabor de los platos, sino que también son buenas para las articulaciones: la cúrcuma, la nuez moscada, la canela y el cilantro tienen efectos antiinflamatorios y bajan la hinchazón. El chile y el jengibre contribuyen a aliviar el dolor. Consuma carne con moderación, preferiblemente carne de ave. El consumo de carne de vacuno y de cerdo debería ser solo ocasional. Evite los productos azucarados y procesados ricos en grasas y el consumo de tabaco y alcohol. En caso de sobrepeso, adelgazar descargará sus articulaciones y contribuirá a que tenga menos dolor de rodilla y a que se sienta en general más ligero y en forma.

Exercise in everyday life

Regular exercise is essential to counteract the progressive changes caused by arthrosis, maintain knee function and relieve pain. You should therefore integrate more exercise into your daily routine. Take the stairs instead of the elevator, run small errands on foot or by bike instead of using the car and relax with an evening walk rather than sitting in front of the television. At work, you can do short exercises during breaks – you’ll see that this isn’t just good for your knee, it also refreshes your mind.

“Exercise is essential for arthrosis patients because muscle inactivity simply results in a joint that is unstable, weak and misaligned. And that’s why exercise, muscle training and compensating for misalignments have to be the key factors in counteracting arthrosis.”

Christian Krone

Modalidades deportivas

Además del movimiento en la vida diaria, practicar con regularidad determinados deportes es lo ideal para mantener la artrosis bajo control. La natación, la gimnasia acuática, la marcha nórdica, montar en bici o dar largos paseos, por ejemplo, preservan la movilidad de la rodilla y previenen el dolor. Asimismo, refuerzan la musculatura de las piernas y fomentan la movilidad y la resistencia en general. El máximo precepto aquí es: muévase mucho sin llegar a sobrecargar el cuerpo. De este modo hará algo bueno por las articulaciones de sus rodillas y se sentirá, en general, mejor y más activo.
Sin embargo, no debería practicar deportes que provoquen una carga excesiva de la articulación de rodilla debido a paradas abruptas, giros pronunciados o presión elevada puntual. Entre ellos se encuentran la mayor parte de los deportes de pelota, el deporte de contacto o el esquí alpino.
