About Sinding Larsen Johansson (SLJ) Syndrome

Sinding Larsen Johansson syndrome commonly affects adolescents and young boys who are physically active during their growth spurts. Adolescents who participate in sports involving running, twisting and jumping such as basketball, football, and gymnastics etc… are more prone to this condition. It results from a mixture of extreme traction or pulling force on patella from patellar tendon in combination with a growth spurt. The condition is also termed as an adolescent equivalent to Jumper’s knee (patellar tendinopathy). Adolescents and young children are affected more easily as their bones, tendons and muscles are still growing and it makes them more vulnerable to this condition. This syndrome often heals on its own once the musculoskeletal system reaches its full maturity.
