Osgood Schlatter Disease
Osgood Schlatter disease is a common cause of pain in the front of knee in children and adolescents. It results in inflammation of the growth plate at the tibia (shin bone) typically between the ages of 9 to 15 years.
Causes
Repetitive stress, increased exercise intensity, jumping sports, change in exercise activity and growth spurts are common contributors to the onset Osgood Schlatter Disease
Increased load through the quadriceps muscle can put increased tension on the attachment of the patella tendon on the tibia.
During childhood the growth plate of the tibia is not fully fused and therefore the patella tendon can irritate this growth plate resulting in inflammation at the knee.
Signs & Symptoms
Pain and tenderness at the top of the shin bone, just below the knee cap.
Palpable bump at the top of the shin bone, below the knee cap.
Pain aggravated by weight bearing exercises such as walking, running and jumping
Usually occurs during ages of growth between 9-15yrs old
More common in males
Differential Diagnosis
Sinding-Larsen-Johannson syndrome
Referred pain from hip
Hoffa’s fat pad irritation
PROmotion Assessment and Outcomes Measures
Subjective examination including assessment of current and previous activity levels, past injury history, aggravating factors, footwear
Assessment of knee and hip range of motion
Palpation of knee and surrounding structures
Assessment of lower limb muscle, strength, control, flexibility and imbalances
Assessment of sporting footwear
How to Manage
Education and advice regarding load management. This will be dependent on the child’s current function and pain levels. Often a period of offloading is required in the early stages if highly irritable.
Advice regarding return to activity and load management. Osgood Shlatter disease is a self-limiting injury and will improve when full skeletal maturity is achieved, however it is important your child is able to stay active whilst managing there injury.
If applicable manual therapy to help improve pain, knee range of motion and decrease muscle tightness.
Prescription of a home exercise program targeted to impairments contributing to symptoms including lower limb and pelvic stability and control, strength and flexibility.
Following assessment of foot biomechanics, if appropriate advice regarding footwear and referral to Sports Podiatrist if necessary for orthotic review.
Management may also include referral to a sports doctor for review if any further medical intervention such as imaging, differential diagnosis and assistance with management plan.
