Osgood Schlatters Disease
Osgood Schlatters disease is a common knee condition in adolescents. It is characterised as an injury to the growth plate at the top of the tibia (shin bone) just below the knee.
The muscle group at the front of the thigh is the quadriceps, these muscles attach to the patella (knee cap), which then attaches to the top of the tibia (shin bone) via the patellar tendon. In individuals who have not yet finished skeletal growth, a growth plate exists where the patella tendon inserts into the shin bone. Every time the quadricep muscles contract, they pull on the patellar tendon which in turn pulls on the tibia’s growth plate. When this force is too high or repetitive, irritation to the growth plate may occur. Irritation will lead to pain and sometimes an increased bony prominence at the front of the shin, known as Osgood Schlatters.
What are the symptoms of Osgood Shlatters?
Pain is generally localised to the front of the knee just beneath the knee cap. The pain may increase during activities requiring strong quadricep contractions, for example, jumping, squatting, going up and down stairs or running. The area where the patellar tendon attaches on to, known as the tibial tuberosity, may be tender to touch or kneel upon. There may also be a visible bony prominence or swelling present at the top of the shin bone.
How can physiotherapy help?
Osgood Schlatters gradually resolves as the patient finishes growing and the growth plate within the knee disappears. Physiotherapy is very useful for patients with this condition as it can reduce pain and allow for increased activity levels. Treatment may include soft tissue massage, stretching, icing, taping/bracing, biomechanical correction, activity modification advice, and exercises to target strength and flexibility of specific muscles.
