NCT07096037

Brief Summary

The primary objective of this clinical trial is to evaluate the efficacy and safety of a topical Urtica dioica cataplasm in managing knee pain and functional limitations in athletic children diagnosed with Osgood-Schlatter Disease. Efficacy will be assessed through changes in knee pain using the Visual Analog Scale (VAS) and functional outcomes using the Knee Injury and Osteoarthritis Outcome Score (KOOS). Three groups will be tested:

  • UDC Group: topical application of Urtica dioica cataplasm
  • Standard Care Group: oral vitamin D supplementation and physical rest
  • Placebo Group: topical application of a placebo cataplasm using Beta vulgaris subsp. cicla

Outcome Measures

Primary Outcomes (1)

  • Pain intensity

    measured using the Visual Analog Scale (VAS), a 10-cm line anchored by "no pain" (0) and "worst imaginable pain" (10). VAS scores will be recorded at each clinical visit during the intervention period.

    At each clinical visit during the intervention period (three times a week during 6 weeks).

Secondary Outcomes (2)

  • Functional knee status

    Assessments will be done at baseline and after 6 weeks.

  • Return to sport

    6 weeks

Other Outcomes (1)

  • Adverse events

    At each follow-up visit during 6 weeks

Study Arms (3)

Urtica dioica cataplasm

EXPERIMENTAL

Topical application of Urtica dioica cataplasm

Other: Urtica dioica cataplasm

Standard Care Group

ACTIVE COMPARATOR

Oral vitamin D supplementation and physical rest

Drug: Vitamin DBehavioral: Resting conditions

Placebo

PLACEBO COMPARATOR

Topical application of a placebo cataplasm

Other: Placebo

Interventions

Participants will receive a warm Urtica dioica cataplasm applied topically on the affected knee, once daily for 60 minutes, three times per week (on alternate days) over a 6-week period.

Urtica dioica cataplasm
PlaceboOTHER

Participants will receive a placebo cataplasm, matched in texture, color, and odor to the active treatment. The placebo is inert and safe for pediatric topical use.

Placebo

Participants will receive oral vitamin D.

Standard Care Group

Reduction in physical activity based on orthopedic advice.
