Comparing two methods of knee stabilization after infection treatment

Impact of the Type of Stabilization in the Two-stage Knee Reimplantation on Reinfection - Prospective, Randomized Study.

Not applicable Interventional Prof A Gruca Teaching Hospital · NCT04446676

This study tests whether using a stem or sleeve method for knee stabilization helps people who have had an infection in their knee feel better and stay infection-free after surgery.

What this trial studies

This clinical trial investigates the impact of two different stabilization methods, stem versus sleeve, in patients undergoing two-stage knee reimplantation due to periprosthetic joint infection. Participants will first receive debridement and spacer implantation, followed by a six-week antibiotic treatment. After ensuring no signs of reinfection, they will be randomized to receive either a stem or sleeve stabilization during the second stage of the procedure. The study aims to evaluate the reinfection rates and overall knee function over a two-year period.

Who should consider this trial

Good fit: Ideal candidates are individuals who have undergone primary knee replacement and are now facing a second-stage reimplantation due to knee infection.

Not a fit: Patients with significant intraoperative bone defects, autoimmune diseases, or other specified health conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved outcomes and lower reinfection rates for patients undergoing knee reimplantation.

How similar studies have performed: While the approach of comparing stabilization methods is not widely tested, similar studies in orthopedic infection management have shown promising results.
