Study 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.

Read the detailed description

This is a prospective cohort study of 51 adolescents (aged 10-14 at baseline) with Osgood schlatter. Participants are followed for two years.

What researchers measure

Primary outcomes

  1. Current knee pain

    Participants self-report if they still have knee pain

    Time frame: 24 months

Secondary outcomes

  1. Pain intensity

    Worst pain in the previous week measured on a visual analogue scale (VAS) from 'no pain' to 'worst imaginable pain'

    Time frame: 24 months

  2. Pain frequency

    Frequency of knee pain divided into (almost daily, several times per week, weekly, monthly, rarely, never)

    Time frame: 24 months

  3. Duration of being pain-free

    Those who no longer have knee pain will be asked how long since their knee pain resoved

    Time frame: 24 months

  4. Medical attention

    Participants will be asked to report if they sought medical attention outside of the intervention

    Time frame: 24 months

  5. Use of pain killers

    Participants will be asked if they use painkillers to manage their knee pain (y/n). If yes, they will be asked how often.

    Time frame: 24months

  6. knee injury and osteoarthritis outcomes score (KOOS) sport and activity subscale

    knee injury and osteoarthritis outcomes score (KOOS) subscale sport and activity. Minimum 0 points, maximum 100points, with 100 points being the best possible score.

    Time frame: 24 months

  7. Sports participation

    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.

    Time frame: 24 months

  8. Health Related quality of life

    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.

    Time frame: 24 months

  9. Sleep

    Participants will be asked if they find it hard to sleep because of their knee pain (not at all, some nights, most nights).

    Time frame: 24 months

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 2, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
