Single-stage surgery with antibiotic-coated implants for hip joint infection prevention

Single-stage Surgery With Antibiotic-loaded Hydrogel Coated Implants Versus Two Stage Surgery for Secondary Prevention of Complex Chronic Periprosthetic Hip Joint Infection SINBIOSE-H.

Not applicable Interventional Centre Hospitalier Universitaire de Saint Etienne · NCT04251377

This study is testing whether a single surgery using special antibiotic-coated implants can help people with hip joint infections recover faster and avoid complications compared to the usual two-surgery method.

What this trial studies

This clinical trial compares a single-stage surgical approach using antibiotic-loaded hydrogel coated implants to the traditional two-stage surgery for patients with chronic periprosthetic hip joint infections. The single-stage method aims to reduce the time to rehabilitation and minimize complications associated with prolonged antibiotic treatment and multiple surgeries. Patients will undergo implant removal followed by immediate re-implantation of a new prosthesis during the same procedure. The study seeks to evaluate the effectiveness and safety of this innovative approach in preventing infection recurrence.

Who should consider this trial

Good fit: Ideal candidates include individuals with chronic periprosthetic hip joint infections who meet specific diagnostic criteria.

Not a fit: Patients with hypersensitivity to hydrogel components or those with a life expectancy significantly limited by other health issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce recovery time and complications for patients suffering from hip prosthesis infections.

How similar studies have performed: While the two-stage surgery is a well-established protocol, the single-stage approach is relatively novel and has not been extensively tested in prior studies.
