Sinding Larsen-Johansson Syndrome

Sinding Larsen-Johansson Syndrome (SLJS) is classified as a repetitive overuse injury leading to juvenile osteochondrosis and traction apophysitis.^1,2 SLJS typically occurs in the adolescent population between the ages of 10-14 and may occur during a growth spurt.^1,2 This syndrome can be diagnosed with radiographic imaging showing fragmentation of the patellar pole (distal/bottom of the patella).¹ One may also experience swelling, pain and tenderness, at the distal pole of the patella leading to functional limitations.¹ If gone untreated, this acute injury can become chronic which causes calcification at the distal pole of the patella and possible life-time impairments. It is important to make an appointment with your Physician to rule out other possible diagnosis such as Osgood-Schlatters Disease (OSD), Jumpers knee syndrome, Bursitis, Iliotibial Band syndrome, and patellofemoral pain syndrome to name a few.¹
