Sinding Larsen Johansson Syndrome
Sinding Larsen Johansson (SLJ) syndrome is a medical condition that affects the knee joint primarily in the teenage population. This condition is categorized as the osteochondroses group of injuries. It causes pain during the growth phase of the teenagers (especially boys) and affects their use of the knee joint. The patellar tendon connects the patella (knee cap) to the lower leg bone. This tendon is also attached to a growth plate and stress to the tendon adversely affects the growth plate by causing inflammation. People between the ages of 10- 15 years are at the highest risk as they are undergoing a rapid growth phase. This condition has the ability to correct itself as the patient attains skeletal maturity.
