Sinding-Larsen-Johansson, or SLJ, syndrome is a debilitating knee condition that most commonly affects teens during periods of rapid growth. The kneecap, or patella, is attached to the shinbone, or tibia, from the patellar tendon. The tendon connects to an expansion plate at the bottom of the kneecap throughout growth.
Repetitive stress on the patellar tendon can make the growth plate within the knee become inflamed and irritated. SLJ mainly develops in children and adolescents between the ages of 10 and 15 because that is when most people experience growth spurts. SLJ is most common in young athletes due to excess or repetitive strain in the knee.
Sinding-Larsen-Johansson, or SLJ, syndrome is 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. Sinding-Larsen-Johansson syndrome is similar to Osgood-Schlatter syndrome. For more information, please feel free to ask Dr. Jimenez or contact us at (915) 850-0900.
