MUSCULOSKELETAL,  PEADS ORTHO

Osgood-Schlatter disorder 

Clinical history

  • Most frequent cause of knee pain in children aged 10 to 15 years.
  • seen in active adolescents, especially those who jump and kick.
  • It is bilateral in 25-50% of patients 
  • age of onset
    • boys 10-15 years
    • females girls 8-12 years
  • Self-limiting but does not resolve until growth has halted
  • Risk factors – jumpers (basketball, volleyball) or sprinters

Symptoms

  • pain on anterior aspect of knee
  • exacerbated by kneeling

Physical exam

  • inspection
  • enlarged tibial tubercle
  • tenderness over tibial tubercle
  • provocative test [ pain on resisted knee extension

Investigations

  • Xray to rule out serious pathology such as:
    • neoplasm
    • acute tibial apophyseal fracture
    • infection

GP management

  • Reassurance parents that this is a self-limiting condition and symptoms will resolve with skeletal maturity (i.e. when the bones finish growing).
  • symptoms typically last from a few months up to 24 months.
  • In some cases, symptoms can persist longer, especially if the patient remains physically active without adequate treatment
  • Activity Modification:
    • Reducing activities that exacerbate symptoms, such as jumping or running, is often recommended.
  • Physical Therapy:
    • Strengthening and stretching exercises, particularly for the quadriceps and hamstring muscles, can help alleviate symptoms.
  • Cold Therapy:
    • Applying ice to the affected area can help reduce pain and swelling.
  • Knee Straps or Braces:
    • These can provide support to the area and reduce strain on the tibial tuberosity.
  • Rest:
    • Adequate rest is crucial, especially during periods of rapid growth or intense sports seasons.
  • Cast immobilization x 6 weeks
    • Casting is rarely required in the management of OSD.
    • It is generally considered only in severe cases where significant pain and functional impairment persist despite exhaustive conservative management.
    • Casting may also be considered if there is a large, painful ossicle that interferes with knee function, or if conservative measures have failed and surgery is not an option or is being deferred

Indications for specialist referral

  • symptoms not resolving with conservative treatment
  • home stretching program
  • symptoms persisting  longer than 18 months
