Patients are unable to walk independently. You are at high risk of disability. indications for endoprosthetics joint replacement:

Surgery for gonarthrosis

Despite advances in modern surgery, surgery is performed when conservative measures have failed. In the third stage of osteoarthritis, the cartilage has been destroyed to such an extent that the function of the joint can no longer be maintained with conservative measures and the patient has to be operated on. The attending physician selects the type of intervention. The choice depends on the severity of the process and the presence of synovitis, the patient's age and activity level, concomitant diseases and physical condition.

In the case of pure osteoarthritis, joint interventions have no long-term effect (pain reduction within one to two years), so arthroscopy for isolated gonarthrosis is considered an outdated tactic. However, in acute meniscal injury, arthroscopy has shown good results. It is a proven technique that allows reconstruction of the ligamentous apparatus and removal of detached cartilage or bone fragments.

An O- or X-shaped bend in the leg leads to increased stress on the knee joint. This can lead to premature osteoarthritis of the joint. With a bone replacement, also known as an osteotomy, the legs can be straightened again and the load can be optimally distributed. As a result, the arthrosis can no longer progress. Such surgeries are recommended from an early age because they are complex, traumatic and are performed in two stages.

Today, endoprosthetics is a modern and effective method of restoring the function of the knee joint. It is well established but still indicated in extreme cases. Only when the pain is constant when walking, exercising or playing sports, when pain medication is needed daily, when not only daily life but also sleep is disturbed (lack of sleep due to pain), replacement with an artificial joint is recommended . Endoprostheses are made of ceramic, plastic or a combination of high-strength and hypoallergenic materials.

cartilage transplant

Much work is currently being done in the field of cartilage transplantation. If cartilage damage can be repaired, this could provide a satisfactory alternative to artificial knee joints.

Rehabilitation after knee surgery takes place on an inpatient or outpatient basis. The role of the patient himself in the recovery process, his motivation and conscientiousness are extremely important. During the postoperative recovery period, the patient is taught to walk, exercises to strengthen the muscular skeleton are performed, and the function of the renewed joint is developed. The rehabilitation phase usually lasts three to six months. After a good period of rehabilitation, the amplitude of the knee joint (after endoprosthesis) is fully restored and the pain has disappeared.

Gonarthrosis surgery is performed at III-IV stages, when other measures do not help. The surgeon and the patient decide together on the type of operation, taking into account the patient's needs, previous illnesses, age and living conditions. The gold standard in orthopedics today is arthroplasty. Despite the traumatic and difficult joint replacement surgery, after a good and hard rehabilitation, the patient regains a full-fledged joint, which allows him to lead a normal life, relieves pain and enables sports.

Why kneecaps?

• arthrosis
• Pain syndromes in athletes such as 'runner's knee', 'jumper's knee', goose foot syndrome and others.
• Bursitis and synovitis
• torn ligaments
• Excessive physical strain on the knee (prophylactic)

The right choice of bandages allows for quick healing and less use of medication. Stabilizers are scientifically proven to lock the knee in the correct position and increase its stability both mechanically and through muscle activation.

knee straps

There is a plethora of different models of knee braces in today's medical market. Every manufacturer tries to offer something new with their products. By and large, however, all knee bandages can be divided into 3 types:

1. Bandages with joints. This type stabilizes the knee joint, and the joints allow the knee to move within limits that do not take into account the possibility of pathological abnormalities.

2. Compression bandages or soft bandages. The main purpose of such a product is the interaction of the patellar material with the skin and muscles. The bandage gently wraps the leg, relieving swelling and reducing pain. The compression changes rhythmically during movement and provides an additional massage effect.

3 stockings with elastic ribs and massaging silicone plates. A modern type of compression bandage with additional stimulation of muscle and ligament receptors.

Many products have additional accessories to make them easier to use, such as B. binding rings, belts or an increased fabric strength. There are also bandages that are designed to treat a specific condition. These include knee brace models for kneecap instability, Baker's cysts and cruciate ligament tears.

Symptoms of gonarthrosis

Common symptoms of gonarthrosis of the knee joint are:

• Severe knee pain when moving;
• dysfunction of the knee;
• swelling in the knee joint area;
• claudication;
• stiffness of the joint;
• Instability of the painful joint.

In the later stages of the disease, deformity (curvature) of the leg also occurs.

In most cases, osteoarthritis of the knee develops slowly and progresses in four consecutive stages.

First stage gonarthrosis of the knee is characterized by the following symptoms:

• Slight knee pain when climbing/climbing stairs, when squatting.
• 'Starting pain' when initiating movements.
• restriction of mobility.
• The discomfort disappears when the patient 'rolls out'.
• Pain in the knee after heavy exertion.
• The knee may appear healthy or slightly swollen.
• Synovitis (inflammation of the inner membrane causing fluid to form in the joint) can occur.

Bilateral second-degree gonarthrosis of the knee joint causes the following symptoms:

• The pain intensifies.
• The symptoms increase rapidly when squatting and walking.
• The pain is localized on the inside of the knees and gradually subsides with rest.
• crunching knees.
• The joint enlarges and fluid begins to collect in it (synovitis).
• Intra-articular fluid can fill a pit at the back of the joint (Baker's cyst).
• The individual joint surfaces feel hot.
• After physical warming, the stiffness may subside.
• The shape of the legs changes in the area of the knees (curvature).

The following symptoms are characteristic of tertiary osteoarthritis of the knee:

Diagnosis of gonarthrosis of the knee.

Diagnosis involves interviewing the patient, examining the inflamed joint, checking its volume, and assessing its range of motion. If there is a suspicion of gonarthrosis, the orthopedist recommends instrumental methods:

• ROENTGEN. In osteoarthritis of the knee, x-rays may show narrowing of the fissures, thinning of the bone beneath the cartilage, and ossification of the articular cartilage. Osteophytes—bony hypertrophies that run along the edge of the cartilage—may be present.
• Ultrasound examination of the knee joint.
• arthroscopy. During the examination, the surgeon inserts a special micro-camera connected to an arthroscope through punctures into the joint. An image of all parts of the examined area appears on the screen.
• Magnetic resonance imaging (MRI). This allows the extent of damage to the knee joints to be assessed.
• The blood test is an additional diagnostic method and does not always give a complete picture of the clinical picture. In the case of gonarthrosis, there may be no signs of inflammation in the blood.

Basic principles of movement therapy in gonarthrosis

Before performing exercises to develop and restore the knee joint in gonarthrosis, a specialist should be consulted. In some cases, therapeutic exercises may require a special approach. The exercises must not be performed with force, must be fun for the patient and must not cause any pain. If discomfort occurs, the exercises should be stopped immediately.

The exercises are tailored to each individual case. They largely depend on the fitness of the patient and the stage of the disease. If gonarthrosis worsens and the knee is swollen and causes severe pain, exercises should be stopped. Sport can be resumed in remission. Start with simple exercises and gradually increase them by increasing the number of repetitions and the duration of the training. Experts recommend combining these exercises with swimming, outdoor walks, and massage. But the most important thing is that you exercise regularly. Only with regular training can you restore the function of your knee joint and strengthen and build up your muscles. Exercises for gonarthrosis have a positive effect on the entire body of the gonarthrosis patient, and also on his psychological and emotional state.

Patients should carefully choose the right athletic shoes for exercise. You should buy sneakers with a flexible, but firm and hard sole. The upper material should preferably be made of natural leather and be soft. Also important are supinators, which support the foot. Good quality footwear for osteoarthritis patients can prevent unwanted injuries that can aggravate the knee joint.

The rest of the clothing should be loose and comfortable and should not restrict freedom of movement. This may also include shorts and a t-shirt or tracksuit. All exercises that are part of the therapeutic complex of exercises for gonarthrosis can be done at home. No special equipment is required, just a mat. For some exercises you need a support, which can be taken over by a simple chair.

Video lesson on therapeutic exercises for gonarthrosis

• Exercise 1. This exercise is also known as 'bicycle'. The starting position for this exercise is lying down with your elbows bent. The legs should be lifted up and the movement should mimic riding a bicycle. If you find it difficult to do the exercise with your elbows, you can also lie completely on your back.
• Exercise 2. This exercise is often referred to as 'scissors' and is similar to scissors. Lie on your back and propped up on your elbows, then cross your legs and raise them. Patients with poor physical preparation should lie on their backs.
• exercise 3 Lie on your back and straighten your legs. Now pull your legs towards you by bending them at the knees and lifting them a few inches off the floor.
• exercise 4 The starting position for this exercise is the same as for the previous one, but the knees must be bent. Alternately, raise each bent leg toward your stomach, then straighten and return to the starting position.
• exercise 5 For this exercise, lie on your side and slightly bend the leg that is on the floor at the knee. Alternately, lift the other leg toward your stomach and pull it back. Repeat this exercise a few times, then roll onto the other side and repeat with the other leg.
• exercise 6 This exercise is performed while sitting on a chair. Bend and straighten your legs with quick movements, one at a time. This exercise is very easy to perform as it doesn't take up a lot of space. Even during a break from work, you can train your knee joints in this way.
• exercise 7 This exercise is also performed on a chair. This time straighten your legs one at a time and hold them at the highest point for a few seconds.
• exercise 8 Pull yourself up on a chair, raise yourself onto your tiptoes and stay at the highest point for a few seconds. Repeat the exercise 5-8 times. Now lift your toes onto your heels.
• exercise 9 Lying on your back on the floor, alternately raise your leg up and hold this position for 30-40 seconds. Start with a shorter time and gradually increase the duration. While performing the exercise with one leg, the other leg should be on the floor and completely relaxed. Therapeutic exercises for gonarthrosis should be supplemented with massage. This can be done independently. To do this, rub your feet vigorously until they feel warm.

Symptoms of gonarthrosis

pain at osteoarthritis of the knee Don't leave immediately. For a long period of time, many months or even years, there is a slight pain that occurs only when walking, during physical exertion, climbing stairs or getting up from a chair.

If the knee pain comes on suddenly and there was no pain before, it usually indicates another condition or injury, such as a heart attack. B. a pinched meniscus or a piece of cartilage that is between the cartilages of the knee.

There are three stages of knee osteoarthritis:

• Gonarthritis (Arthritis) Stage I is characterized by limb fatigue, a slight restriction of movement in the joint, and possibly a mild grinding sensation. The pain usually occurs at the beginning of walking ('start-up pain') or after prolonged exertion. There is no pain at rest or with slight exertion. In the first stage, the bones of the knee retain their original shape and are only slightly deformed. X-rays show a slight narrowing of the joint space.
• Stage II osteoarthritis of the knee Movement restrictions occur. At this stage, pain accompanies almost every movement in the affected knee. However, the knee hurts particularly badly after walking for a long time or carrying light loads. The pain syndrome subsides only after a long period of rest. There is a noticeable crunching in the knee joint with movement, deformation of the joint, muscle hypotrophy and limping. On x-ray, the joint space is 2-3 times narrower than normal and osteophytes (marginal bony hypertrophy) appear. Synovitis (accumulation of pathological fluid in the joint) at this stage osteoarthritis of the knee Synovitis (accumulation of fluid in the joint) is much more common and severe at this stage of gonarthrosis than at the onset of the disease in the first stage.
• In the third stage of gonarthrosis In the third stage of gonarthrosis, the pain in the knee is even stronger. The mobility of the knee joint is reduced to a minimum. Third stage pain osteoarthritis of the knee The pain also persists at rest and does not subside after the rest phase. The bones in the knee joint are clearly deformed. The patient has difficulty finding a comfortable position in bed and positioning the affected knee in a way that does not cause pain. When the destruction of the joint is combined with poor circulation, the joints start to 'twist' in the middle of the night, usually when the weather changes - 'in the rain'. On the x-ray, the joint separation has almost completely disappeared. The articular surface is distorted, marginal hypertrophy is evident.

Conventional Osteoarthritis of the knee joint is divided into two types: primary and secondary.

Symptoms of gonarthrosis

The disease begins insidiously. In the first stages, patients experience slight pain with movement, especially when climbing and descending stairs. Stiffness in the joint and a feeling of tension in the tendons can occur. A characteristic symptom of osteoarthritis of the knee is 'tear pain' - a painful sensation that occurs with the first steps after rising from a sitting position. When the patient with osteoarthritis of the knee 'runs out', the pain subsides or disappears, but reappears after significant weight bearing.

Externally, the knee is unchanged. Sometimes patients with gonarthrosis notice a slight swelling of the affected area. In some cases, at the first stage of gonarthrosis, fluid accumulates in the joint – synovitis develops, which is characterized by an increase in the volume of the joint (it becomes swollen, spherical), a feeling of heaviness and limitations in movement.

In the second stage of gonarthrosis, the pain increases even with light exertion, and intensifies with intensive or prolonged walking. The pain is usually limited to the anterior surface of the joint. The pain usually subsides after prolonged rest and returns with movement.

As gonarthrosis progresses, the mobility of the joint gradually decreases, and severe pain occurs with maximum flexion of the leg. A harsh crunch may be heard with movement. The configuration of the joint changes as if it were enlarged. Synovitis is more common than stage I gonarthrosis and is characterized by a more persistent course and the accumulation of more fluid.

With stage III osteoarthritis of the knee, pain is almost constant and affects patients not only when walking, but also at rest. Patients spend a lot of time in the evening trying to find a comfortable sleeping position. It is not uncommon for the pain to also occur at night.

The flexion of the joint is significantly restricted. In some cases, not only flexion but also extension is limited, so that the osteoarthritis patient cannot fully straighten the leg. The joint is swollen and deformed. Some patients develop a valgus or varus deformity—the legs take on an X or O shape. The restriction of movement and deformation of the legs makes gait unstable and faulty. In severe cases, patients with osteoarthritis of the knee can only walk with the help of a cane or crutches.

diagnosis

The diagnosis of osteoarthritis of the knee is made on the basis of the complaints, objective examination and radiological data. Patients with stage I osteoarthritis of the knee usually do not show any external changes. In stage II and III gonarthrosis, thickening of the bone contours, joint deformation, restricted movement and curvature of the extremity axis are found. A grinding sound is heard when the kneecap is moved laterally. Palpation reveals a painful area on the inside of the kneecap, at the level of the joint space, and above and below the surface of the joint.

With synovitis, the joint increases in volume and its contours become flat. There is swelling at the anterolateral articular surfaces and over the patella. Fluctuations are noted on palpation.

X-ray of the knee is the classic technique for clarifying the diagnosis, determining the extent of pathological changes in gonarthrosis and monitoring the progression of the process through repeated exposures over a period of time. Due to its availability and low cost, it is still the most important method for diagnosing osteoarthritis of the knee. In addition, it can be used to exclude other pathological processes (e.g. tumors) in the tibia and femur.

In the early stages of gonarthrosis, X-rays cannot show any changes. Later, narrowing of the joint space and thickening of the subchondral surface can be observed. The articular ends of the femur and especially the tibia are enlarged, and the edges of the condyles are sharpened.

When analyzing X-ray images, it should be borne in mind that more or less pronounced changes characteristic of gonarthrosis are present in most elderly people and are not always accompanied by pathological symptoms. The diagnosis of osteoarthritis of the knee can only be made by a combination of radiological and clinical signs of the disease.

Functions of a knee brace

The main functions of this type of products are fixation, pressure relief and correction. Knee braces are used as a preventive measure to stop the progression of pre-existing joint deformities and prevent re-traumatization of the affected area. The main purpose of these aids is to improve the functioning of the musculoskeletal system. Orthotics can allow the joint to flex or completely immobilize the leg. In other words, dynamic orthotics help reduce pain and improve function in the lower limbs while allowing some range of motion. While static orthotics ensure complete rest and stabilization in a fixed position.

When answering the question 'How do I choose a knee brace?' it is important to consider the function of the orthosis:

• Flexible knee orthosis - ensures a slight immobilization of the knee joint.
• Knee orthosis with spiral stiffening ribs - used in chronic diseases: ligaments, arthrosis, synovitis.
• Kneecap joint brace - semi-rigid fixation works well in osteochondropathies, contractures of the knee joint.
• Orthosis – used in the treatment of Kenig's disease and in the acute phases of synovitis, hemarthrosis and synovitis.

When are orthoses used?

The most important parameters to look for when choosing an orthosis are the design, size and material of the orthosis. Before you buy a knee brace, you should consider that its design must be adapted to the type of disease or injury. There are several basic types of these products:

– With closed patella – available with soft or rigid elastic side panels (OS6211 and 9104 Orliman, Spain). There are also products with an integrated round silicone insert (Genumedi® 611/613 and Protect.Genu P776 Medi, Germany) and tension-regulating straps (Genumedi® Plus 613P, Medi and 9106, Orliman);

– With open patella and lateral ribs (polycentric joint). Some models have an integrated ring-shaped silicone insert (9105, Orliman), as well as special straps (9107/ 4104S /7104S Orliman, Stabimed® 826, Medi, 0659/0660, DJO USA).

– Rigid orthoses (890/891/892/893 Medi, 94260 Orliman, 0452/0453/0870/0871/0872/0873/1029/1030/1600/1601/DJO)

– Telescopic orthoses with a wide range of motion control and locking options (0961, DJO USA).

Before choosing a knee brace, three measurements should be taken:

Before purchasing an orthosis, it is important to consult your doctor who will tell you what type of product you need depending on the type of injury or illness. The consultants in orthotic stores can help you choose a model and determine the correct size. How long a knee brace (for therapy) should be worn is determined by the doctor after examining the leg. For a knee brace that is worn prophylactically or for sports, there are no restrictions on how long it can be worn, but the product must be removed at night.

Why do I need knee pads for osteoarthritis?

Medical knee pads strengthen the muscles around the joint, maintain bone strength, conserve energy and improve the overall quality of life. When the knee joint is affected by osteoarthritis (actual destruction of the cartilage within the tissue), its biomechanics are disrupted. Additional stabilization is required. This stabilization prevents unnecessary friction in the knee, stimulates cell regeneration and thus relieves pain. The knee ligaments also improve blood and lymph circulation. Swelling is eliminated and the functionality of the joint is improved.

Knee bandages for arthrosis have some distinctive features: most models are equipped with a special patellar ring, that is, a small element that encloses the middle of the kneecap and firmly fixes the meniscus. This gives extra support and prevents unnecessary movements that could damage the cartilage. Therapeutic knee pads can also have a warming effect and are made of wool, neoprene or cotton.

Knee orthoses for arthrosis form a separate group. These are special models with a sophisticated fastening system and medium to high rigidity. If you have decided to buy knee braces for osteoarthritis, we recommend that you consult your doctor before visiting an Ortomedical salon. The doctor will perform a diagnostic examination, determine the extent of the joint damage and prescribe a suitable knee brace model with the appropriate stiffness.

How do I choose the right knee brace for osteoarthritis?

When choosing a knee brace for osteoarthritis, you should use the following guidelines:

1. Kneecap type and design (with or without patellar ring, insulated or athletic, etc.).
2. Degree of fixation (flexible, medium or extra stiff).
3. Size (according to manufacturer's size chart).
4. Materials (wool, cotton, neoprene, etc.).
5. Closure system (strap/clip/velcro).

When choosing a knee pad, it is important to know what purpose you need the product for: treatment, prevention, sport, etc. The following groups of people can benefit from the use of a knee brace

• Patients with osteoarthritis and other similar degenerative-dystrophic diseases;
• People who are overweight (every extra kilogram negatively affects the joints);
• Pregnant women (because of the increased load on the lower limbs and as a prophylaxis against varicose veins)
• Athletes (athletes and people who play heavy sports).

The price of a kneecap depends on the manufacturer and the complexity of the design of the bandage. The rigidity of the product and the materials used also affect the price. High-quality knee braces can be purchased at very reasonable prices from the Orthomedical chain of stores.

Preoperative preparation for endoprosthetics and special features

Which type of knee arthroplasty is suitable for a specific patient is decided by the surgeon during the examination. The preoperative examination program includes a number of standard examinations. Before using prostheses, a general practitioner is consulted.

It is important to treat chronic infections prior to prosthetics. For this purpose, the patient is referred to a dentist, otolaryngologist and other specialists. Performing this procedure requires a first-class operating room, which is not available in every inpatient department.

The operation usually takes no more than two hours. Joint replacement surgeries are performed under combined anesthesia. The anesthetics are administered in the perioperative room. Intravenous support is also provided.

About 10 percent of operations are performed under endotracheal anesthesia. With endoprostheses, blood loss of between a hundred milliliters and one liter is possible. In 10 % of the cases, the patients require an intraoperative or postoperative hemotransfusion.

recommendations for patients

A person can improve their postoperative prognosis on their own. Important after a knee endoprosthesis Boost the immune system, eat a healthy diet, practice good hardening habits, and take weight-loss steps. These measures will help your body to recover from the operation and adapt to the changed conditions more quickly.

Before knee replacement surgery, patients must learn exercises that exercise the joints and strengthen the muscles. These are used after the operation during the rehabilitation period.

This speeds up the recovery process after knee arthroplasty. It is also important that the patient learns to use the rehabilitation aids correctly: crutches, walking aids, sticks.
