Abstract

Background: Osgood–Schlatter Disease (OSD) is a traction apophysitis of the tibial tuberosity commonly occurring in physically active adolescents, particularly in sports involving repetitive jumping and rapid directional changes. This condition may lead to anterior knee pain and functional limitations.

Objective: To describe the clinical outcomes of a structured physiotherapy exercise program in a badminton athlete with OSD.

Methods: A case report was conducted on a 14-year-old male badminton athlete diagnosed with OSD in the progressive loading phase. The patient underwent six physiotherapy sessions over two weeks. The intervention included functional and plyometric exercises such as runner’s climb exercise, single-leg squat, squat jumps, box jumps, single-leg hop, and speed skaters. Outcome measures included pain intensity using the Visual Analog Scale (VAS), knee range of motion (ROM), muscle strength assessed by Manual Muscle Testing (MMT), and functional performance using the Kujala Anterior Knee Pain Scale.

Results: Pain decreased from VAS 1 (palpation) and 2 (movement) to 0 and 1, respectively. Knee flexion improved from 110° to 125°, while muscle strength remained at 5/5. Functional performance increased, with the Kujala score improving from 65 to 76 points.

Conclusion: A structured physiotherapy program incorporating functional and plyometric exercises may improve pain, joint mobility, and functional performance in adolescents with OSD. Findings should be interpreted cautiously due to the single-case design.
