One-Stage Exchange Arthroplasty: A Surgical Technique Update

Area of Science:

• Orthopedic Surgery
• Infectious Disease Management

Background:

• Periprosthetic knee infection is a serious complication following knee replacement surgery.
• Standard treatment involves a two-stage surgical exchange to ensure infection eradication before reimplantation.

Purpose of the Study:

• To describe a single-stage surgical technique for managing chronic knee periprosthetic infections.
• To evaluate the efficacy of this single-stage approach in eradicating infection and restoring function.

Main Methods:

• A single-stage surgical exchange procedure for chronic knee periprosthetic infection was performed.
• The technique emphasizes controlling infection, preventing recurrence, and restoring joint function.
• Local and systemic antibiotic delivery was integrated into the surgical protocol.

Main Results:

• The single-stage exchange technique demonstrated high success rates in managing chronic knee periprosthetic infections.
• Infection eradication rates were comparable to those achieved with the traditional two-stage exchange method.
• The technique successfully restored function in patients with chronic knee periprosthetic infections.

Conclusions:

• A single-stage exchange surgery is a viable and effective option for chronic knee periprosthetic infections.
• When performed under appropriate conditions and with antibiotic support, it offers comparable outcomes to two-stage exchange.
• This approach provides a successful alternative for infection control and functional restoration in affected patients.
