Summary

Osgood-Schlatter is a growth-related condition involving multiple different types of tissue in the tendon-bone interface at the tibial tubercle. Osgood-Schlatter affects one in ten adolescents causing persistent pain and reduced ability to maintain physical activities. Changes in rate of torque development is associated with decreased neuromuscular functioning and pain chronicity, thereby affecting athletic performances and general physical activities. However, changes in rate of torque development has not been investigate in patients with Osgood-Schlatter and could help characterize the condition and guide management. The aim of the study is to investigate early and peak rate of torque development during maximal voluntary isometric knee extension and knee flexion in adolescents with Osgood-Schlatter, compared to a matched group of asymptomatic adolescents (controls), in a cross-sectional study. The study will include 13 adolescent participants with Osgood-Schlatter and a group of 13 pain free controls matched on sex, age, and sports participation on the group level. Testing will include rate of torque measurements of knee extension and flexion for each limb with a fixated handheld dynamometer during a single test-session lasting approximately two hours. The examiner responsible for strength-testing will be blinded to case-status. Along with anthropometric data, participants will perform the anterior knee pain provocation test to assess pain-response to sustained knee loading, a countermovement jump test to assess power and jump height, and provide patient-reported measures of condition severity, pain, disability, and quality of life. Data collection will start March 2023 and is expected to finish by May 2023.

Conditions

• Osgood-Schlatter Disease

Interventions

Type	Name	Description
OTHER	Rate of torque development testing of knee flexors and knee extensors using a fixated handheld dynamometer (MicroFet 2, Hoggan, Scientific L.L.C., Salt Lake City, USA), sampling rate of 100hz)	Participants and their parents/guardian receives information about the test procedures. Written informed consent is obtained before clinical examination and testing. Clinical testing is performed, anthropometric values are obtained and patient reported outcome measure is filled out, before the tests are performed. Cases will receive treatment for their condition and controls a movie ticket as compensation.
