Kneecap jumped out

A cracked kneecap (patella) or kneecap dislocation refer to physicians as patellar dislocation. The kneecap jumps out of its slide bearing and usually shifts to the outside. It is one of the most common injuries of the knee joint and affects especially young athletic people. There are two types of patellar luxations, which are differentiated according to their cause. On the one hand, the kneecap can pop out due to an accident-related trauma. Of these, mostly teenagers are affected. On the other hand, the kneecap dislocation can occur due to the plant without a previous event. In the following, the symptoms, the causes, the diagnosis and the forms of therapy with a cracked kneecap are explained.

definition

A cracked knee sprain (patellar dislocation) refers to an injury to the knee joint in which the patella jumps out of its sliding bearing and usually shifts to the outside. It is not uncommon for the crack or tear of the inner bands of the knee.

Symptoms: Symptom Patella jumped out

The patella is a flat, V-shaped and free-running bone in front of the knee joint, which protects it and reduces the friction of the four-headed thigh muscle on the one hand and on the other hand strengthens its leverage, so that the maximum extension of the knee is possible. The patella is connected to the knee joint capsule by tendons, ligaments and muscles. It slides up and down on the thighbone (femur) when the knee joint moves in a normally fitting plain bearing. Due to the high forces that occur in the patellar joint, and a stabilized only by tendons, ligaments and muscles joint guidance, it may come to jump out of the kneecap for various reasons.

Patellar dislocation is very painful, with knee pain being most severe below the knee and on the inside of the kneecap, and immediately recognizable by a typical deformation of the knee. In addition, severe swelling of the knee joint due to articular effusion may occur if bleeding occurs due to ligament injuries. As a result, there is usually a restriction of movement of the knee. In some cases, small cartilages or pieces of bone break out due to the patellar dislocation, which can pinch in the joint and later cause damage to the cartilage and osteoarthritis of the knee.

Athletes are particularly affected by a trauma-related dislocation of the kneecap, for example, if the affected person receives a strong kick against the knee with the leg extended and the thigh muscles not strained or taut. Footballers are therefore more likely to suffer from patellar luxation. Sometimes impact accidents can cause the kneecap to pop out.

If the kneecap jumps out without a previous accident, it is usually a plant-related cause. This may for example be the case when the plain bearing, in the "track" the kneecap normally runs, is too flat. It is also possible to have a patella dysplasia or a patellar sting, which is often the result of an accident. Other plant-related causes of patellar dislocation may include the X-legs (genu valgum), a patellar shift to the opposite side and a general connective tissue weakness.

risk factors

The risk factors for pop-out of the kneecap relate primarily to the plant-related possible causes. Since women are more frequently affected than men, female sex is one of the risk factors for patellar dislocations. A general connective tissue weakness, axis misalignments as it occurs in X-legs, malformations of the patella or its plain bearing, disorders or weaknesses of the thigh extensor muscles as well as accidental or plant-related kneecap elevation are also included. In addition, sports such as football pose an increased risk of knee injuries.

diagnosis

If a kneecap jumps out of its slide bearing, it usually shifts outward. This can be seen from a visual diagnosis due to the typical deformation of the knee. Frequently, the kneecap spontaneously repositions itself, so that manipulation is no longer necessary. Sometimes a medical history survey is necessary if, for example, no accident or trauma of patellar luxation has preceded it. If necessary, measures are necessary to prevent the re-jumping out of the kneecap.

After the kneecap has returned either by itself or by manipulation back to their original position, a joint effusion is often visible and tactile. The areas on the inside of the kneecap and on the outer edge of the trough on the thigh are usually pressure sensitive and painful. In a so-called apprehension test, the doctor gently pushes the kneecap outwards to provoke a renewed patellar dislocation to find out if the patient's kneecap has previously popped out. If this is the case, the patient defends against pressing, because he already knows the feeling, or the Knischeibe can be moved beyond the slide bearing out.

Further examinations can be carried out by means of X-rays, magnetic resonance tomography (magnetic resonance imaging, MRI) or arthroscopy (joint mirroring). In the latter, small joint or cartilage pieces can be removed at the same time and joint flushing can be carried out.

treatment options

In order to avoid consequential damage, the treatment of a cracked kneecap should take place as early as possible. In most cases, the kneecap springs back to its original position by itself. However, if the patellar dislocation persists, it must be returned to the plain bearing by manipulation of a physician. Similar to a shoulder excursion increases with each further dislocation of the patella, the risk of renewed patellar dislocation. Although there is no causal conservative form of therapy, however, appropriate muscle training and the wearing of certain orthoses can reduce the risk of further incidents of this kind.

In addition, when an articular effusion occurs, a puncture may be necessary that not only drains the blood but also helps relieve pressure and relieve pain.

If, nevertheless, the patella pops out again or if there is cartilage or bone damage, surgery may be necessary. Depending on the cause and nature of the symptoms, different procedures can be used. Often a capsule removal or Patellazu gelation is performed, so that the path of the patella is predetermined and stabilized during movements.

Naturopathy therapy

If the kneecap pops out once or more frequently, a visit to the osteopath can make sense and provide information about the cause, which in the osteopathic view can affect all structures that have an influence on the statics of the body. It examines and, if necessary, treats all factors that can lead to tensions on or around the kneecap. An example of this is the iliotibial tract, a tendon that runs from the outer joint of the tibia where it connects to the lateral band of the patella and further to the thigh. On the Tractus are, among other things, the so-called Chapman points, treatment points that correspond to the intestine. Since the same nerves also supply parts of the intestine here, interactions are assumed in osteopathy. (No)
