Knee arthrosis causes therapy rehab

Knee osteoarthritisKnee osteoarthritis describes the Wear of the articular cartilage in the knee. As a result, the bones rub against each other more, causing more joint fluid to form. Inflammation develops, pain, redness and swelling occur. The disease leads to severe Movement restrictions.

What is knee osteoarthritis?

Knee osteoarthritis is also known as gonarthrosis. It may affect the inside or outside of the knee or the knee joint. Three forms are distinguished:

– Medial arthrosis in the inner side of the knee – Lateral arthrosis in the outer side of the knee – Patellofemoral arthrosis under the kneecap

Often occur Mixed forms on. Joints. About half of the women. One third of men over the age of 60. About half of the women. One third of men over the age of 60. are affected at the age of 60. The disease occurs more frequently in older age, but younger people are also affected.


At the beginning of osteoarthritis Pain occur exclusively during exertion. Sports activities, such as walking and running, increase the pain. Later, knee pain becomes more intense and frequent. Every movement is then perceived as painful. Swelling. Redness becomes visible. In the third stage, sufferers feel the pain even at rest, including at night.

In the course of the disease have stiffening of the joints. The complaints show up clearly in the morning after getting up, after sitting for a long time or in the evening. The progressive wear and tear of the joints in the knee can reduce mobility. Enormously restrict the quality of life of the affected person.

Causes and risk factors

The knee joint is the connection between the kneecap (patella) and the bones of the thigh and lower leg. The ends of the bones are surrounded by cartilage, a white substance. The healthy cartilage provides for the sliding ability. Allows low-friction movement of the knee. If the Cartilage thinner, softer or cracked the friction can no longer be mitigated, Pain develops.

Often there are injuries or. Overloads at work or during sports at the beginning of knee osteoarthritis. As Risk factors apply:

– congenital deformities – posture disorders – meniscus damage – incorrect loading of the joints after accidents and injuries – circulatory disorders – gout – lack of exercise

By the way, the wear of cartilage is a natural process of aging. Not all wear and tear requires therapy.

Diagnosis of knee osteoarthritis

After taking your medical history (anamnesis) by a specialist in orthopedics the Examination of the leg and the musculature as well as the evaluation of the gait pattern. The outer and cruciate ligaments of the knee are checked. The measurement of Muscle functions using EMG (electromyography) provides important information. The orthopedist checks the condition of the Meniscus.

Parallel to the examinations, the specialist questions the patient in order to be able to draw precise conclusions about the cause of the pain and the localization of the osteoarthritis. The orthopedic examinations are determined by Imaging procedures (MRI, CT, X-ray) supports.

What therapy is recommended?

There is a widespread amption that osteoarthritis cannot be improved, but only slowed down. This no longer applies to most patients today. There are Effective joint-preserving procedures available.

The conservative treatment

The goals of conservative treatment of osteoarthritis are Vslowing down the wear and tear on the joint and the Alleviation of symptoms. This form of treatment does not require surgery. Conservative therapy includes, among other things:

– Physiotherapy to strengthen muscles and relieve tension – Reduction of malpositions through orthotics – Exercise programs – Nutritional counseling – Weight reduction – Physical therapies (heat, cold)

The combination of various conservative forms of treatment can relieve pain and improve mobility.

The medicinal treatment

The aim of drug treatment for gonarthrosis is to Reduction of pain and inflammation. It takes place in three stages:

1. Non-opioid pain therapy 2. Treatment with weakly acting opioids 3. Treatment with strong opioids

Painkillers are administered as ointments, patches, tablets or injections.

The surgical treatment

If conservative measures are unsuccessful, surgical therapy may be considered. These include:

– Arthroscopy of the joint (knee arthroscopy) – Cartilage transplantation – Knee replacement (knee prosthesis)

Pain-free again with knee prosthesis

If the functionality of the knee joint is severely disturbed and cannot be restored by other measures, the knee joint can be replaced by a knee prosthesis. The following are available Full and partial prostheses. The costs of the treatment are covered by the health insurance company.

When a full knee prosthesis (knee TEP) is used, the knee joint and the joint surfaces on the thigh and tibia are replaced with metal, ceramic or plastic. All parts can slide on each other again. In addition to open surgery, in many cases a Minimally invasive surgery take place. The decision depends, among other things, on the progress of the disease, the patient's physical condition and the type of prosthesis to be used. The operation is performed on an inpatient basis. It lasts several hours. The stay in the hospital lasts about two weeks. Physiotherapy with initial movement exercises begins in the hospital as early as two to three days after insertion of the artificial knee joint. After about 10 days the wounds are healed.

Rehab for knee arthrosis

In the case of a normal course Immediately after the hospital stay or, at the latest two weeks after discharge, a three-week treatment period Follow-up treatment (AHB) at. Depending on the type of knee prosthesis used and the patient's condition, this orthopedic rehabilitation measure can be inpatient or outpatient take place. The goal is to improve mobility. Supporting the healing process. The patient learns under professional guidance the Movement with the new joint. The rehab program includes lymphatic drainage, gait training, and physical therapy, as well as counseling on reintegration into working life.

The costs of rehabilitation are covered by the pension insurance for employed persons. If the knee arthrosis is occupational, the statutory accident insurance is a possible cost bearer. Pensioners are also entitled to rehabilitation after knee joint surgery: In order to avoid the need for nursing care, the costs are covered by the health insurance companies. In the application process, z. B. the social service in the hospital.

Knee joint replacement: When can I return to work after the operation??

After successful completion of rehab, most patients can move safely again with the new knee joint. Depending on the course of recovery and the type of activity, the patient can return to work after a few days on average three months.


Pain in the knee means a loss of quality of life. This does not have to be. Modern medicine offers effective treatment options. Initially, conservative therapies such as physiotherapy, manual therapy, and lifestyle changes are the treatment of choice. If this does not lead to the desired success, an artificial knee joint can lead to a life with new mobility and without pain. Subsequent rehabilitation ensures that you are once again safe and mobile with the knee prosthesis.
