Our research group advances translational orthopaedic science by combining biomechanics, biomaterials research, implant design and clinical evaluation. Our current projects focus on improving implant longevity, surgical safety and patient-specific treatment strategies.

We conduct a comprehensive analysis of mechanical, material and biological determinants of polyethylene wear in total hip arthroplasty. By integrating tribological testing, retrieval analysis and cellular response models, we aim to better understand wear particle generation and the associated periprosthetic tissue reaction.
 

Relevance:
Reducing wear and osteolysis is key to improving long-term implant survival and lowering revision rates.
 

Using imaging-based 3D modelling and additive manufacturing, we develop anatomically matched osteosynthesis plates tailored to individual patients. Mechanical performance and clinical feasibility are systematically evaluated.

Relevance:
Patient-specific fixation may enhance stability, reduce operative time and improve functional outcomes.
 

We are validating a newly developed instrument for safe and efficient removal of bone cement in revision arthroplasty. Bench testing and comparative analyses focus on safety, efficiency and bone preservation.
 

Relevance:
Improved cement removal techniques can reduce complications and preserve bone stock during revision procedures.
 

Fragility fractures of the femoral neck are an increasing challenge in ageing populations, and conventional hip stems are not optimised for fracture treatment in frail patients.
This project develops a stem specifically designed for this population, with emphasis on enhanced primary stability, optimised load transfer and immediate full weight-bearing. Development integrates anatomy-guided design, mechanical testing and early clinical evaluation.

Relevance:
A dedicated stem for fragility fractures aims to improve implant stability, reduce complication rates and support early mobilisation in a vulnerable patient group.
 

We are analysing data from the oldest hip prosthesis register in Switzerland to assess long-term outcomes, implant survival and complication patterns. Registry-based research enables large-scale outcome evaluation across decades.

Relevance:
Registry data provide high-level evidence to guide implant selection, surgical techniques and quality improvement strategies.
