Brief Summary:
Osgood Schlatter is a common knee condition, affecting approximately 10% of adolescents. OSD is thought to be a growth related pain conditon, and thus resolve after maturation. Despite this, there a lack of prospective data investigating whether this is in fact the case.

Observational Model: Cohort
Time Perspective: Prospective
Official Title: A Prospective Investigation of Osgood Schlatter With 24 Month Follow-up
Actual Study Start Date : July 10, 2018
Actual Primary Completion Date : December 1, 2018
Actual Study Completion Date : February 28, 2019

Group/Cohort Intervention/treatment
51 adolescents with Osgood Schlatter who participated in an activity modification intervention.
Other: Activity modification
Activity modification, exercises and gradual return to sport

Primary Outcome Measures :
  1. Current knee pain [ Time Frame: 24 months ]
    Participants self-report if they still have knee pain

Secondary Outcome Measures :
  1. Pain intensity [ Time Frame: 24 months ]
    Worst pain in the previous week measured on a visual analogue scale (VAS) from 'no pain' to 'worst imaginable pain'

  2. Pain frequency [ Time Frame: 24 months ]
    Frequency of knee pain divided into (almost daily, several times per week, weekly, monthly, rarely, never)

  3. Duration of being pain-free [ Time Frame: 24 months ]
    Those who no longer have knee pain will be asked how long since their knee pain resoved

  4. Medical attention [ Time Frame: 24 months ]
    Participants will be asked to report if they sought medical attention outside of the intervention

  5. Use of pain killers [ Time Frame: 24months ]
    Participants will be asked if they use painkillers to manage their knee pain (y/n). If yes, they will be asked how often.

  6. knee injury and osteoarthritis outcomes score (KOOS) sport and activity subscale [ Time Frame: 24 months ]
    knee injury and osteoarthritis outcomes score (KOOS) subscale sport and activity. Minimum 0 points, maximum 100points, with 100 points being the best possible score.

  7. Sports participation [ Time Frame: 24 months ]
    Participants will report if they participate in sport. If yes how often and how much/week. They will also report if they have reduced sports participation due to knee pain.

  8. Health Related quality of life [ Time Frame: 24 months ]
    Health related quality of life assessed by EQ 5D 3L Y (EuroQol, 5 dimensions, 3 levels for youth). Minimum 0, maximum 1, with higher values indicating higher quality of life.

  9. Sleep [ Time Frame: 24 months ]
    Participants will be asked if they find it hard to sleep because of their knee pain (not at all, some nights, most nights).
