Does use of a biologic agent increase the incidence of postoperative infection in surgery for rheumatoid arthritis after total joint arthroplasty?

Objectives: The goal of the study was to examine the influence of biological agents on postoperative infections such as surgical site infection (SSI) and late infection in patients with rheumatoid arthritis after total joint arthroplasty at our hospital between January 2006 and December 2011.

Methods: The patients were divided into groups with (Bio group, 267 joints) and without (Non-Bio group, 300 joints) treatment with biological agents. We examined the incidence of postoperative infection in Bio group and Non-Bio group.

Perioperative complications in elective surgery in patients with rheumatoid arthritis treated with biologics.

We retrospectively investigated the influence of biological agents on delayed wound healing and the occurrence of postoperative surgical site infection (SSI) in patients after surgery for rheumatoid arthritis. The patients were divided into two groups-those with and without treatment with biological agents (276 and 278 joints, respectively)-and adverse events (delay in wound healing and SSI) were investigated. Wound healing was delayed in 11.

Analysis of the kinematics of total knee prostheses with a medial pivot design.

Analysis of the kinematics of the FINE Total Knee System (Nakashima Medical, Okayama, Japan) revealed that the medial condyle is fixed and the lateral condyle shows lateral posterior movement and tibial internal rotation. Analysis of the kinematics of the ADVANCE Total Knee System (Wright Medical Technology, Arlington, Tenn) revealed that the medial condyle is fixed and the lateral condyle shows anterior movement in the early stage, changing thereafter to posterior movement. With regard to rotation, initial external rotation subsequently changes to internal rotation.

Compartment syndrome of bilateral lower extremities following laparoscopic surgery of rectal cancer in lithotomy position: report of a case.

A 67-year-old man underwent laparoscopic surgery for rectal cancer in the lithotomy position. After surgery he complained of bilateral lower limb pain, swollen legs, and sensory disturbance. The serum creatine kinase value was 46 662 U/l.
