Joint kinetics have been estimated via inverse dynamics with link-segment models to analyze the performance of non-articulated energy storage and return (NA-ESR) prosthetic feet [1] and to examine the motor control strategies and compensations adopted by lower limb amputees [2]. A central assumption of the link-segment model commonly used in this application is that the ankle’s axis of rotation...

Lactobacillus is a gram-positive rod bacteria found primarily in the gastrointestinal and female genital tracts. Prosthetic infections in implants are being increasingly reported. The authors present a case of a 58-year-old patient with Lactobacillus septic prosthetic knee joint infection. To the authors’ knowledge, this is the first reported case of chronic prosthetic knee infection with isola...

Total Hip Replacement is a method of prosthetic reconstruction of the acetabulum and proximal femur following hip joint destruction. Prosthetic fractures have been reported after primary surgery ; with majority of them at the prosthetic stem. Few had fracture through neck of prosthetic stem. Here, we report a rare case of fracture neck of prosthetic stem within 10 year of implantation in a pati...

Extended-spectrum beta-lactamase-producing Enterobacteriaceae have increasingly become a public health issue in a variety of infections, including urinary tract infections and postoperative infections. The complications that occur due to these organisms in bone, joint, and prosthetic joints have not been well defined. This study reviewed the clinical characteristics, risk factors, and outcomes ...

We present the first published case of Coxiella burnetii prosthetic joint infection. Diagnosis was established with PCR and culture of periprosthetic tissue and synovial fluid (and serology). A novel PCR assay is described herein. Q fever should be considered in patients with prosthetic joint infection without an identified pathogen.

This study aimed to identify, by systematic review of the literature, whether intra-articular steroid injection before total joint replacement confers an increased risk of post-operative deep prosthetic infection. All studies assessing the incidence of deep prosthetic infection in patients who had undergone steroid injection in the same joint were included. A mixed meta-analysis and narrative r...

Prosthetic joint infection is an unfortunate though well-recognized complication of total joint arthroplasty. An iliacus and/or iliopsoas muscle abscess is a rarely documented presentation of hip prosthetic joint infection. It is thought an unrecognized retroperitoneal nidus of infection can be a source of continual seeding of the prosthetic hip joint, prolonging attempts to eradicate infection...
