No direct link between dental procedures and prosthetic joint infection

The American Academy of Orthopaedic Surgeons (AAOS), and the American Dental Association (ADA) found that there is insufficient evidence to recommend the routine use of antibiotics for patients with orthopaedic implants to prevent infections prior to having dental procedures because there is no direct evidence that routine dental procedures cause prosthetic joint infections.

No differences between computer-navigated and traditional TKA related to knee function, pain

For many years, the use of computer-assisted navigation has been touted as improving the positioning, sizing and alignment of replacement knee joints, resulting in greater durability of joints and overall improvement in patient movement. However, new research published in the Journal of Bone and Joint Surgery (JBJS) found no difference in knee function, alignment or durability/survivorship between joints positioned and completed with the help of computer navigation, and those replaced with conventional total knee arthroplasty (TKA) procedures.
