In young athletes with their underdeveloped bone system, the bones are more supple, the cartilage is softer, and the ligaments, on the contrary, are more powerful. Therefore, if some burden in an adult athlete leads to a rupture of the tendon or ligament, then in a junior a similar burden can cause a fracture of the apophysis or pineal gland. If the treatment is not carried out correctly, there will be a violation of bone development – Osgood-Schlatter disease. This disease was first described at the very beginning of the 20th century. It occurs most often in boys aged 11 to 15 years. The reason is the injury (rupture) of the patella ligament in the area where the ligament is attached to the tuberosity of the tibia. Symptoms of the disease are pain and some localized swelling of the soft tissue.Osgood-Schlatter’s disease An x-ray shows changes in the ligament in different ways, and this depends on the age of the injured and on what stage of the disease. The picture should be taken in lateral projection, while the limb should be slightly turned inward. The picture should be decrypted by an experienced doctor, taking into account the structure and degree of ossification of the tuberosity of the tibia. A picture needs to be taken several times, after some periods of time. At a time when the tuberosity is still completely cartilaginous, the picture may not reveal any changes, but after a couple of weeks the picture may show areas of ossification or even a torn fragment. In older patients with already formed centers of ossification, changes can be seen immediately.
When the disease goes into the chronic stage, soft tissue edema will decrease, those pieces of bone that have undergone changes may increase slightly in size – the phase of enchodal ossification begins, as an option – a corn is formed. Broken bone fragments can connect with each other over time, and also attach to the tuberosity, which can also increase in size and cause discomfort, and in especially severe cases, even come off.
Treatment of the disease should include rest, walking exclusively with crutches, applying ice, the use of medications against edema or inflammation. Before the symptoms of the disease disappear, a program for the full rehabilitation of the quadriceps should be started. Usually by the end of adolescence, the disease usually completely and completely disappears. However, especially severe cases of the disease require surgical intervention. There may be complications – the tuberosity of the tibia does not grow together, the knee becomes concave, the patella ligament is shortened, special cases – chondromalacia and subluxation of the patella ligament.
Knee injury prevention measures
Proper workout before volleyball.
The right technique. The athlete should change the technique of jumping and landing so that the load on the patellar ligaments is minimal. This can be achieved by reducing the hallux tension on the legs during the jump, which consists in the fact that the athlete should try to keep his legs together during the jump. During touchdowns after the jump, try not to squat heavily.
The right training. The training should minimize the practice of jumping on a solid floor, while the load, duration and frequency of training should be increased gradually.
Proper rehabilitation. Only after the consequences of the injury have passed completely, the athlete can start training. Otherwise, there is a chance that it will not be possible to avoid repeated injury, in addition, previously earned tendonitis can become chronic. Do not forget about special exercises that help strengthen the patellar ligaments.
The correct bandage. Leading world rehabilitologists advise wearing special knee pads equipped with a special ring in the rehabilitation period, although detailed studies on this topic have not been conducted.
Prevention of volleyball injuries of the PKS – anterior cruciate ligament also has some of its own characteristics. To prevent such injuries, the athlete should try after landing to land on legs bent at the knees. At the same time, it is forbidden to bend the knees strongly in order to avoid the development of tendonitis, so that the landing does not end with a deep squat and overstrain of the patella ligaments. This applies to both defense games and attacks.
