Abstract
Background
A common knee complaint during adolescence, a crucial time for staying physically active, is Osgood Schlatter (OS). Activity ladders has been used for knee pathologies in adolescents to guide progression of loading during rehabilitation. They are based on order of expected symptom provocation from common activities. It is, however, unknown how adolescents with OS rate the level of aggravation from common activities.
Purpose / Aim of Study
To obtain self-reported ratings of common activities by adolescents with OS in order to rank them and comprise a activity ladder.
Materials and Methods
Adolescent patients with OS attending a specialized orthopedic clinic filled out a survey containing twenty-three activities, all of which were nominated as important by previous patients. Activities were rated by participants on a 5-point Likert scale ranging from 0 “does not provoke knee pain” to “provokes extreme knee pain” and subsequently ranked in groups (most, second most/least, and least aggravating activities) using median scores (x̃) and individually using mean (x̄) scores.
Findings / Results
Thirty-three patients (age 13.5±1.7 years, symptom-duration 23.6±16.1 months) participated. Activities were ranked in 3 groups (median scores 4, 3 and 2). The most aggravating activities (x̃ 4) were kneeling (x̄ 3.9), sprinting (x̄ 3.8), acceleration (x̄ 3.7), landing (x̄ 3.6), high-speed running (x̄ 3.6), and deceleration (x̄ 3.5). The second-most/least aggravating activities (x̃ 3) were squatting (x̄ 3.3), climbing stairs (x̄ 3.3), fast/hilly cycling (x̄ 3.2), one-legged jumping (x̄ 3.2), side-ways change of direction (x̄ 3.1), walking fast or for a long distance (x̄ 3.0), two-legged jumping (x̄ 2.9), jogging (x̄ 2.8), kicking a ball (x̄ 2.7), and backwards change of direction (x̄ 2.6). The least aggravating activities (x̃ 2) were getting up from chair/toilet (x̄ 2.7), side-ways running (x̄ 2.5), light cycling (x̄ 2.5), skipping (x̄ 2.4), prolonged standing (x̄ 2.4), kicking in the air (x̄ 2.4), and walking shortly (x̄ 2.2).
Conclusions
For adolescents with OS, knee pain is provoked especially by kneeling and high-velocity sports-specific actions. These findings can form the basis for an OS-specific activity ladder to guide rehabilitation.
