Revision total knee arthroplasty (TKA) is the treatment of choice in patients with periprosthetic joint infection. It may be performed in either a single stage or two stages. In the latter option, between stages, an antibiotic-loaded spacer may be ...

During primary total knee replacement, the knee joint is replaced with an implant, or prosthesis, made of metal and plastic components (parts). There are three parts to a knee replacement implant: Femoral; Tibial; Patellar

2016年8月4日 · By simultaneously delivering high local concentrations of antibiotics and preserving the soft tissue envelope, bone cement spacers can be beneficial to both the patient and the revision knee surgeon. A well-made cement spacer confers stability to the knee, enhances early patient mobilization, and limits a patient’s period of disability.

2023年4月10日 · Several types of articulating spacers are reportedly available, including hand-made spacers, spacers fashioned from molds, commercially preformed spacers, spacers with additional metal or polyethylene elements, new or autoclaved prosthesis, custom-made articulating spacers, and 3D printing-assisted spacers.

2022年7月15日 · Revision surgery is the most common treatment for patients who develop infection after total knee arthroplasty (TKA). Two types of spacers are often used in revision surgery: dynamic spacers and static spacers. The comparative efficacy of these two types of spacers on knee prosthesis infections is not well established.

2021年3月11日 · The gold standard treatment for infected total knee arthroplasty (TKA) is two-stage revision. The first stage involves a temporary antibiotic spacer, which can be static or articulating; it remains unclear which is best. We aimed to compare 5-year outcomes between static and dynamic spacers.

2022年4月16日 · The 1.5-stage exchange TKA details placement of an articulating spacer for an indefinite period, prolonging revision until reinfection, deterioration of functional status, or construct failure. A 1.5-stage revision TKA technique is a viable option for treatment of chronic periprosthetic knee infections.

2019年9月23日 · In 1988, Cohen published a case-series of 3 prosthetic joint–infected total knee arthroplasties (TKAs) treated with antibiotic-loaded cement acting as a static spacer. These patients achieved excellent results with no evidence of loosening at 24-36 months and range of motion (ROM) 90-100 degrees [17].

Explantation and placement of an antibiotic spacer is a well-recognized treatment for periprosthetic infection after total knee replacement. Although static spacers may be occasionally indicated, many patients benet from an articulating spacer …

2013年11月29日 · Two-stage revision arthroplasty using an articulating cement spacer can be an effective therapy not only for the treatment of an infected TKA but also for recovery of knee ROM and function. Keywords: Knee, Infection, Revision total knee arthroplasty, Two-stage.
