About this trial

The primary aim of the clinical investigation is to demonstrate the efficacy of a silver-based antimicrobial coating on hip implants in the reduction of periprosthetic infections in revision hip arthroplasty due to periprosthetic infection.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Patients > 18 years

Patients indicated for unilateral cementless acetabular and hip stem revision due to chronic periprosthetic infection (according to EBJIS definition): single-stage or two-stage surgical procedure according to clinical standard at the clinical investigation site

According to the assessment of the clinical investigator, the subject is therapy compliant and able to attend the follow-up visits

ASA physical status I - III

Disqualifiers

Simultaneous participation in another interventional clinical trial (drugs or medical devices studies)

The investigational implant components (femoral and/or acetabular) are not suitable for the patient anatomy or bone defect

Patients who require plate osteosynthesis at the implantation site

Patients with an already implanted silver-coated device

Trial design

Trial outcomes

Primary outcomes

1

Occurrence of periprosthetic joint infections

Participants are monitored for 12 months after revision surgery. Every case of periprosthetic joint infection according to the definition of the EBJIS classification counts.

Time frame
12 months

Secondary outcomes

1

Change of functional outcome over follow-up period (Harris Hip Score (HHS))

Harris-Hip-Score: The Harris Hip Score (HHS) is a clinical tool used to evaluate the function of the hip joint, particularly after hip surgery or in cases of hip disease. The HHS consists of 10 items divided into four categories: Pain (maximum 44 points) Function (maximum 47 points) Range of Motion (maximum 5 points) Deformity (maximum 4 points)

Time frame
2 years post operative
2

Changes in quality of life

Measure Description: EQ-5D-5L The EQ-5D-5L is a standardized instrument used to measure health outcomes. Developed by the EuroQol Group (EQ), it assesses five dimensions (5D) of health: Mobility Self-care Usual activities Pain/discomfort Anxiety/depression Each dimension has five levels (5L) of severity: no problems, slight problems, moderate problems, severe problems, and extreme problems

Time frame
2 years post operative
3

Implant survival

Measure Description: Kaplan-Meier implant survival Kaplan-Meier Analysis is a standard statistical method to describe the survival of human subjects or medical products over a defined time period. The revision-free survival rate is the performance indicator of the product under investigation and confirms the clinical outcome of the hip prosthesis. Information on survival of the implant will be collected until the last follow-up of the study patients took place.

Time frame
2 years post operative
4

Radiographic assessment

radiographic measurements to assess implant migration, signs of loosening and changes in the fixation area over time

Time frame
2 years post operative
