Summary

Researchers at University Hospital Bonn are following 300 adults who undergo knee or hip replacement surgery to understand how their recovery unfolds. The study measures quality of life, hand grip strength, and bone density before and after the procedure. The goal is to identify factors that influence surgical outcomes and long-term health. This is an observational study, meaning participants receive standard joint replacement care without any experimental treatment.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Joint replacement surgery (arthroplasty)
What this could lead to
If successful, this study could help doctors better predict and improve recovery after knee or hip replacement, leading to more personalized care plans.
What could go wrong
This is an observational study, so it won't test a new treatment. Results may not apply to all patients, and the measures used may not capture every aspect of recovery.

Who is studied

In this longitudinal study, subjects will be recruited from the patient population of the orthopaedic outpatient clinic of the Clinic and Polyclinic for Orthopaedics and Trauma Surgery at the University Hospital Bonn. A total of 300 patients will be included. This explorative study design is based on the number of cases and the number of operations performed in recent years at the University Hospital Bonn, which amounts to approx. 550 arthroplasty operations per year.

Ages

18 to 100 years
