Osgood-Schlatter’s Disease Flashcards
What is Osgood-Schlatter’s Disease (OSD)?
Osteochondrosis of the tibial tubercle, typically only occurring in the immature athletic population.
How does OSD present clinically?
Atraumatic AKP localised to Patella Tendon insertion at the Tib Tuberosity.
What causes OSD?
Repetitive extensor mechanism stress in skeletally immature athletes.
What is treatment for OSD?
Symptomatic management with Ice, NSAIDs activity modification and rest from aggs.
Followed by stretching and strengthening regiment.
What is the Aetiology of OSD?
During bone maturation, males 10-12, females 12-14.
Repeated traction over the tib tubercle leads to microtears and evulsion.
What can happen with severe cases of OSD?
Can lead to a partial avulsion of hte tibial tubercle apophysis or a full avulsion fracture with added trauma.
What is the Epidemiology of OSD? (distribution in population)
Highly common in adolescent athletes
~12% of males and 8% of females.
What is the diagnostic procedure for OSD?
Radiological imaging is not usually required, typically only done if an avulsion fracture is suspected.
What is the Bilateral Correlation of OSD?
Symptoms are Bilateral in 20-30% of cases.
What is the Prognosis of OSD?
Excellent prognosis, the condition is self-limiting and usually recovers within a month or two. Sometimes persists up to 2 years if untreated.
What findings would indicate OSD?
POP tibial tuberosity, worsened with activity.
+ve Ely’s Test and pain resisted isometric KE.
Describe the Management of OSD:
Conservative only.
P.R.I.C.E., NSAIDs, Activity Modification and limiting aggravation.
Low-intensity Quads strengthening and stretching
McConnell Taping for activity
Ely’s Test can indicate OSD, describe what this test is and what it measures:
Patient lies prone and PT passively flexes the knee, +ve test if heel cannot touch buttock without hip rising (or pain/spasticity).
Measures Rec Fem tightness.
Sinding Larsen Johansson Syndrome is another juvenile osteochondrosis of the knee. Tell me how this differs from OSD:
SLJS - Pain at the lower pole of patella
OSD - Pain at tibial tuberosity (below patella)
Tell me about the use of bracing, casting and corticosteroids for OSD:
They are sometimes used in extreme circumstances but evidence and consensus is against these.
