What is the avulsion of the patellar ligament?

The Sinding-Larsen Johansson Syndrome is a rupture or avulsion of the patellar ligament at the distal point of the patella caused by traction. The patellar ligament or tendon is the distal part of the tendon of the M. Rectus Femoris, part of the quadriceps femoris, which is a continuation of it. It goes over the patella and is attached to the tibial tuberosity. It’s other attachment is the spina iliaca anterior inferior. The most superficial fibers originate from the rectus femoris, the deepest layer from the vastus intermedius and the intermediate layer from the vastus lateralis and vastus medialis.

What is the condition of the kneecap?

Sinding Larsen Johansson syndrome is an inflammation of the bone at the bottom of the patella (kneecap), where the tendon from the shin bone (tibia) attaches. It is an overuse knee injury rather than a traumatic injury. The syndrome usually appears in adolescence, during the growth spurt.

Why do I have knee pain?

Knee pain is a well-known symptom which can occur due to a variety of knee injuries and/or conditions, including sports injuries. The knee is one of the most complex joints in the human body as it is made-up of the intersection of four bones, four ligaments, various tendons, two menisci, and cartilage. According to the American Academy of Family Physicians, the most common causes of knee pain include patellar subluxation, patellar tendinitis or jumper’s knee, and Osgood-Schlatter disease. Although knee pain is most likely to occur in people over 60 years old, knee pain can also occur in children and adolescents. Knee pain can be treated at home following the RICE methods, however, severe knee injuries may require immediate medical attention, including chiropractic care.

What is the muscle group at the front of the upper leg called?

The large muscle group at the front of the upper leg is known as the quadriceps. When straightening the leg, the quadriceps pull to deliver the leg forward. This puts pressure on the growth plate at the bottom of the kneecap. During rapid growth, the bones and muscles don’t always grow at precisely the same rate.

What sports cause knee pain?

Sports that involve a lot of running and jumping, such as field and track or other sports such as football, gymnastics, basketball, lacrosse, and field hockey, can place stress on the knees. Increased or incorrect physical activity can add strain on the knees.

What is the pain at the bottom of the knee?

What is SLJ in medical terms?

Sinding-Larsen-Johansson, or SLJ, syndrome is medically referred to as a juvenile osteochondrosis which affects the patella tendon in the kneecap which attaches to the inferior pole of the patella in the shinbone. Commonly characterized by knee pain and inflammation, SLJ is considered an overuse knee injury rather than a traumatic injury.

Diagnosing Sinding-Larsen-Johansson syndrome

Clinical evaluation is typically enough to make a diagnosis. The pain can cause loss of function in the individual. This usually manifests as being unable to jump, unable to kick the ball hard, etc. Cold weather usually makes it worse, and the condition improves with warm weather.

Treatment for SLJ syndrome

The goal of treatment is to alleviate pain while maintaining normal activities as much as possible. This is usually done through a combination of stretches, icing the area, and anti-inflammatory medications.

When can I resume physical activity?

You can do strengthening and balance exercises once the pain has subsided to try to prevent the pain from returning. Doctors recommend practicing alternative training, or doing activities like cycling or swimming, which don’t require running or jumping.

How old is Sinding Larsen?

Is a thickening of the proximal patellar tendon seen?

Early findings are subtle or absent. Thickening of the proximal patellar tendon may be seen with possible stranding of the adjacent portions of Hoffa's fat pad. Dystrophic calcification and/or ossification may eventually occur.

What causes knee pain in children?

Sinding-Larsen-Johansson lesion or syndrome is one of a group of injuries known as osteochondroses which cause knee pain in children. Other similar injuries include: 1 Osgood’s Schlatter disease – is a chronic stress injury to the bottom of the kneecap. 2 Sever’s disease – causes pain at the back of the heel.

What causes a jumper's knee?

It is caused by a combination of excessive traction on the patella from the patella tendon and usually a period of rapid growth.

What is bipartite patella?

A bipartite patella occurs when the patella has a natural split in it and is not the result of a fracture. Cases of Sinding-Larsen-Johansson usually correct themselves once the skeleton matures.

Growth plates

Up until we are fully grown, we have so-called growth plates located at the ends of long bones such as the shinbone (tibia) and thighbone (femur). These growth plates consist of cartilage to which tendons of muscles are attached. When the body grows, the tendons can pull on and irritate the cartilage.

Better with time

Osgood-Schlatter and Sinding-Larsen-Johansson syndromes are self-limiting conditions that improve with time, but it can take up to 1 year to be symptom-free.

Causes

Osgood-Schlatter and Sinding-Larsen-Johansson syndromes are common in athletes who participate in sports with lots of sprinting and jumping, for example, athletics, football, volleyball, and basketball. They may be a result of repeated jumping and landing with volleyball and basketball players, or repeated long kicks with football players.

Diagnosis

The diagnosis is made on the basis of symptoms. An experienced doctor or physiotherapist will make an accurate diagnosis. These conditions can often be confused with patellofemoral pain syndrome (PFPS), which has some similarities but is more common in girls than boys.

Treatment

Both are treated the same. When symptoms flare up, ice can be an effective way to reduce pain, but the most important measure is to adjust the level of activity. This might involve refraining from certain activities which cause a lot of pain for a while so that the symptoms can subside.

Be honest!

Ignoring your symptoms is not recommended. Pushing through the pain or masking symptoms by taking painkillers like NSAIDs will in most cases prolong the rehabilitation period.

Epidemiology

  • Unlike "Jumper's Knee" which is seen at any age, SLJS is seen in active adolescents, typically between 10-14 years of age. 1. Children with cerebral palsy are also prone to SLJS.
See more on physio-pedia.com

Etiology

  • SLJS is caused by traction on the patellar ligament, causing inflammation at the insertion of the proximal ligament into the inferior pole of the patella. The extensor mechanism of the knee comprises the quadriceps tendon and muscles, patella, patellar ligament and the supporting retinaculum. Injuries can occur from direct trauma, overuse, degenerative disease. The most co…
