Department

Orthopaedics and Sports Medicine

Our goal is to keep people mobile as long as possible by improving therapeutic interventions. We study risk factors and (molecular) processes of skeletal growth & development disorders, sport & traumatic injuries and osteoarthritis.

About our Department

Our research

The mission of the department of Orthopedics and Sports Medicine is: “to promote sustainable improvement in physical activity, empowering individuals to lead healthier lives “. By implementing a comprehensive strategy, we aim to maintain global leadership in the field, focused on sustainable mobility and physical activity of the population, prevention of musculoskeletal (MSK) disorders, accessible and equal care for all patient groups, and innovative and cost-effective surgical and non-surgical treatments to optimize the use of the critical capacity of care.
The research strategy of our department is focused in 4 research lines:

‘Prevention and early treatment of osteoarthritis’

‘Musculoskeletal growth and development’

‘Exercise as medicine and healthcare for sports injuries’

‘Technology for Complex Musculoskeletal reconstructions’

LSR

Our aim was to evaluate the comparative effectiveness of all available treatments for Achilles tendinopathy in a regularly updated (“living”) systematic review using a network meta-analysis. We plan to keep updating this review every 2 years. Future results will be posted here every 2 years. When there are clinically relevant changes that impact clinical decision-making, we will plan to publish a new update as scientific article.

SET-study

Objective of current study is to compare continuous passive motion with physical therapy (CPM) versus early motion supervised physical therapy (PT) versus outpatient delayed physical therapy (DPT) as rehabilitation protocol after surgery for posttraumatic elbow contractures in a prospective randomized controlled trial, comparing elbow range of motion at 8 weeks, 5 months and 1 year after treatment.

SOS-Elbow

The aim of this study is to develop such an instrument for signaling overuse sports injuries in the pediatric elbow (SOS-Elbow).

SUSPECT-study

Patients with a clinically suspected scaphoid fracture and normal initial radiographs are treated with 2 weeks below-elbow cast. However, only 10% of these patients has eventually a scaphoid fracture. Therefore, we are treating most patients unnecessary.
