Sinding Larsen Johansson and Osgood Schlatter syndromes are often found in athletes who are involved in sports with plenty of jumping and sprinting like volleyball and basketball. Generally, boys in the age group of 12-15 years who are in the midst of a growth spurt are more susceptible, but even girls can be affected. Both Osgood Schlatter and Sinding Larsen Johansson are particularly common in children and adolescents.

However, they are differentiated by the spot where the pain originates. In Osgood Schlatter, the pain is situated at the top of the shinbone, whereas in Sinding Larsen Johansson, the pain is concentrated just below the kneecap. In both conditions, in addition to conservative treatment, the phytocannabinoid CBD can be effective in managing pain and inflammation caused by an overloading of the growth plate which contains cartilage on which the tendons of muscles are attached.

What Sinding Larsen Johansson Syndrome Means

Sinding Larsen Johansson (SLJ) syndrome is an aching knee condition that generally affects adolescents during their rapid growth. While we are developing, the patellar tendon connects to a growth plate beneath the kneecap. Continuous stress on the patellar tendon can result in inflammation and irritation on the growth plate. SLJ is an overuse knee injury instead of a traumatic injury.

What Causes Sinding Larsen Johansson Syndrome?

In teen athletes or skeletally immature individuals, Sinding Larsen Johansson syndrome arises from a traction injury of the knee extensor mechanism at the patellar ligament joint and the inferior pole of the patella. Powerful constant quadriceps contractions leads to a traction force on the inferior pole which disturbs the undeveloped bone. Children become more prone to Sinding Larsen Johansson syndrome during the (2nd) apophyseal stage of bone development when their bones are not able to bear high tensile forces.

A likely cause for Sinding Larsen Johansson syndrome can the underdevelopment of quadriceps in contrast to the femur. When there is growth spurt in teens, the lengthening of  the muscle is not able to cope with the speedily lengthening femur, which raises the tensile force on the patella.

Symptoms Related To Sinding Larsen Johansson (SLJ)

Some of the signs which indicate that the knee pain might be SLJ are:

  • Pain at the anterior portion of the knee, below the kneecap which is the primary symptom of SLJ
  • Inflammation and tenderness near the kneecap
  • Pain that gets worse with stair climbing, jumping, exercise, running and becomes severe with kneeling or squatting

Treat SLJ With Caution And Naturally

SLJ does not get resolved until the bones have completely developed and the growth plates are totally closed. During such time, knee pain can emerge and subside during activity. As a precaution you have to refrain from any activity that disturbs and irritates your knee. You can even apply the RICE formula of Rest, Ice or cold compress and Elevate.

Often anti inflammatory or painkilling drugs are also prescribed to assuage pain and lower swelling. But, such painkillers can have adverse side effects that are injurious to health.

However, the plant derived cannabidiol CBD has nil psychoactivity, causes no side effects and drug tolerance, is a natural painkiller and an anti inflammatory compound with a host of therapeutic properties. This compound can be equally effective in treating SLJ syndrome as it can offer the following medicinal benefits:

Works Like An Analgesic And Handles All Types Of Chronic Pain

To reduce the debilitating knee pain in Sinding Larsen Johansson syndrome, the analgesic properties of CBD can be handy as due to its biological properties it can interact with various signalling pathways and receptors within the body like serotonin receptors and RPV-1 receptor to name a few. CBD can efficiently attenuate inflammatory neuropathic as well as pain. The analgesic qualities of CBD can be attributed to its interaction with the alpha3 glycine receptors which helps to decrease persistent inflammatory and neuropathic pain.

The pain relieving properties of CBD are also related with its effect on the level of anandamide, an endogenous cannabinoid in the serum. By increasing the anandamide concentration in the serum, CBD curbs its degradation and the longer anandamide stays in the serum, the greater it will be effective in controlling pain.

Manages All Kinds Of Inflammatory Conditions

Cannabinoids like CBD can work upon the CB2 receptor of the endocannabinoid system which regulates the immune response. An overactive immune response can aggravate inflammation as the immune cells become hyperactive and recruit more cytokines which are pro inflammatory cells. CBD stimulates caspase, an anti inflammatory protein with starts the process of immune cell death, thereby controlling the inflammation and reducing the cytokine production. This can vastly help in lowering the inflammation of the growth plates and kneecap pain in SLJ.

Effective In Muscle Weakness And Stiffness

CBD relaxes the muscles and heals muscle spasms, strains, and stiffness. Muscle contractions arise because of the chemical messengers reaching the muscle and forcing its contraction. Its endocannabinoids only, which can assist in slowing down the excess chemicals which causes severe muscle contractions. CBD helps to supplement the endocannabinoids within the body and also assists in reducing the surge of chemical messengers which ultimately promotes muscle relaxation and mitigate muscle weaknesses.


The vast therapeutic use of the plant compound CBD to treat a variety of medical conditions that is involved with chronic and neuropathic pain, inflammatory disorders, muscle, tendon and ligament tear, bone fractures, tumor growth, and cell proliferation makes it a healing plant medicine. This plant cannabinoid supplements the endogenous cannabinoids present inside the body and works upon the endocannabinoid system of our body to promote homeostasis and ensure the optimum functioning of various biological processes. In addition, CBD has surfaced as a potential therapy to NSAIDs and other drugs as it has potent pain alleviating and anti inflammatory properties with nil side reactions and causes no drug tolerance.
