Long-term antibiotics means using an antibiotic for an extended course rather than a short, “typical” prescription. In orthopedics, it most often relates to treating or suppressing infections involving the knee joint, bone, or implanted hardware. It may be given by mouth (oral) or through a vein (intravenous), depending on the organism and the site of infection. The exact plan varies by clinician and case.

Debridement antibiotics and implant retention is a treatment approach for certain infections involving a joint implant, such as a knee replacement. It combines surgical cleaning of infected tissue (debridement) with targeted antibiotic therapy while keeping the existing implant in place (implant retention). It is most commonly discussed in the setting of periprosthetic joint infection (infection around a knee or hip arthroplasty). The goal is to control infection without removing and replacing the entire implant.

DAIR procedure stands for **Debridement, Antibiotics, and Implant Retention**. It is a treatment approach for certain **infections involving a joint replacement**, including knee replacements. The goal is to control infection while **keeping the existing implant in place**. It is most commonly discussed in the context of **periprosthetic joint infection (PJI)** after arthroplasty.

An Articulating spacer is a temporary implant placed inside a joint to maintain space and allow motion. It is most commonly discussed in the setting of knee replacement complications, especially infection. It is designed to bridge time between surgical stages rather than serve as a permanent joint. In many cases it is made from bone cement and may include antibiotics, depending on the clinical plan.

A Static spacer is a temporary implant placed inside a joint space, most commonly the knee. It is often used during staged surgery for an infected knee replacement. It helps keep the joint space open while limiting motion. Many Static spacer designs can also carry antibiotics within bone cement.

An Antibiotic spacer knee is a temporary implant placed inside the knee joint that contains antibiotics. It is most commonly used during treatment of a knee joint infection related to a knee replacement. It helps maintain joint space and deliver medication locally while infection is being addressed. In many care plans, it is a bridge between surgeries rather than a final, permanent implant.

A Spacer knee is a device or implant used to “space” the knee joint surfaces apart in a controlled way. It is most commonly discussed as a temporary spacer placed during complex knee replacement surgery, especially when infection is involved. In everyday terms, it helps maintain knee shape, alignment, and motion while a longer-term plan is carried out. Different designs exist, and the exact materials and goals vary by clinician and case.

One-stage revision knee is a type of revision knee replacement done in a single operation. It typically involves removing existing knee replacement parts and implanting new parts during the same surgery. It is most commonly discussed in the setting of suspected or confirmed infection around a knee implant. It may also be used for selected non-infectious (aseptic) failures when a full revision is needed.

Two-stage revision knee is a surgical strategy used to replace a failed or infected knee replacement in two separate operations. It is most commonly used when a total knee arthroplasty (knee replacement) is affected by infection or complex failure. The first stage removes problem components and addresses infection risk, and the second stage rebuilds the joint with new implants.

Arthroscopic washout knee is a minimally invasive procedure that rinses the inside of the knee joint with sterile fluid. It is performed using an arthroscope, which is a small camera inserted through small skin incisions. It is commonly used in orthopedics and emergency settings when clinicians need to remove inflammatory or infectious material from the joint. It may also be used to improve visualization and assess internal knee structures during arthroscopy.
