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


Osteoarthritis is a progressive and degenerative disease of the joints that causes impaired mobility and pain. It affects all joint tissues: cartilage, bone, synovium, tendons and ligaments. How these changes are orchestrated is not fully understood. We currently have no cure for osteoarthritis. At the end stage, joint replacement surgery is the main treatment option. By gaining more insight in osteoarthritis etiology, we aim to develop new treatments that can prevent the development of OA or delay the need for joint replacement surgery.


Sports & traumatic injuries

More and more patients are consulting sports physicians and orthopedic surgeons for injuries of cartilage, bone, tendon or ligaments due to trauma or sports. When these injuries are left untreated, there is a significant risk for the development of degenerative joint diseases. Our research focusses on the effectiveness of different treatment options and the development of new treatments to regenerate the damaged structures.


Skeletal growth and development

Changes in the joint shape and bone density in the developing joint are studied to relate observed joint changes to clinical symptoms, progression of the disease, environmental factors and genetic factors. To improve treatment, it is of importance to understand the processes that take place when the joint develops. Pathologies of the hip that occur in childhood and adolescence, such as dysplasia, CAM impingement, Perthes disease and slipped capital femoral epiphysis, have our special attention.

Upcoming defenses

On Thursday 18 February 2021 Letizia Vainieri will defend her thesis entitled "Towards cartilage regeneration: Biomaterial-assisted cell-free approach in a physiological joint-like environment".

Repairing cartilage damage in a joint is a major challenge in orthopaedics. Cartilage damage does not heal spontaneously and can lead to osteoarthritis, a chronic degenerative disease and is one of the leading causes of disability in the aging population. The main aim of the research for this thesis was to improve the quality of the repair tissue using an injectable hydrogel. In order to find better repair treatments, attention was needed to develop laboratory models to gain a better understanding of the different signals that influence cell decision-making and promote cartilage repair. First, an ideal hydrogel was selected that supported cell ingrowth and the formation of cartilage tissue. Subsequently, a laboratory model was set up in which we dynamically load the injectable hydrogel, as would happen in a joint while walking. To further mimic the environment in the joint, the gel was applied in a defect we made in the cartilage of a bovine joint obtained from the slaughterhouse. With this laboratory model, we tested hydrogels and biomolecules for their ability to promote the intrinsic repair capacity of the tissues in the body under joint-like conditions without using laboratory animals.
