Extended Oral Antibiotic Prophylaxis in High-Risk Patients Substantially Reduces Primary Total Hip and Knee Arthroplasty 90-Day Infection Rate.

Background: Total joint arthroplasty (TJA) episodic payment models shift risk and cost of periprosthetic joint infection (PJI) to surgeons and hospitals, causing some to avoid treating high-risk patients. Furthermore, there are little data to support optimization of host factors preoperatively to decrease PJI, and recent literature supports using extended antibiotic prophylaxis following reimplantation TJA. The purpose of this study was to evaluate whether extended oral antibiotic prophylaxis minimized PJI after primary TJA in high-risk patients.

Contemporary Dual Mobility Head Penetration at Five Years: Concern for the Additional Convex Bearing Surface?

Background: Dual mobility (DM) bearings are increasingly popular and second-generation designs contain highly cross-linked polyethylene. The purpose of this study is to report head penetration rates in modern DM bearings.

Methods: A review of 63 consecutive DM bearings was performed.

Mid-term Results of Femoral and Tibial Osteotomies and Fassier-Duval Nailing in Children With Osteogenesis Imperfecta.

Background: Patients with osteogenesis imperfecta (OI) have significant burden of both fractures and bony deformities. The present approach to care in this disorder is a combination of surgical care with intramedullary rod fixation, cyclic bisphosphonate therapy, and rehabilitation with goal of maximizing patient function and quality of life.

Methods: Retrospective chart review identified 58 children with OI who had realignment osteotomies with Fassier-Duval (FD) intramedullary nailing of the lower extremity by a single surgeon.

Periprosthetic joint infection: the economic impact of methicillin-resistant infections.

The orthopedic community has begun to witness a worrisome rise in the incidence of periprosthetic joint infections (PJIs) caused by resistant organisms. Besides other challenges associated with treating these infections, it appears that these infections may pose a higher cost compared to infections caused by sensitive organisms. Significantly higher cost of care for treatment of infections due to methicillin-resistant organisms were seen at a mean of $107,264 per case compared to $68,053 for treating PJI caused by sensitive strains (P < .

Irrigation and debridement in the management of prosthetic joint infection: traditional indications revisited.

Irrigation and debridement (I and D) is a procedure commonly used for the treatment of acute periprosthetic infection. This study retrospectively reviewed clinical records of patients with periprosthetic infection of the hip or knee who underwent I and D with retention of their prostheses between 1997 and 2005 at a single institution. One hundred four patients (44 males and 60 females) were identified.

Early failure of a nonmodular titanium femoral stem after primary hip arthroplasty.

Fully porous-coated cementless implants have a low failure rate and excellent survivorship in primary and revision surgery. Failure secondary to implant fracture is extremely rare with modern implant designs. We report an early fracture of a fully porous-coated femoral stem after primary total hip arthroplasty.
