The Influence of Postoperative Coronal Alignment on Tibial Migration After Total Knee Arthroplasty in Preoperative Varus and Valgus Knees: A Secondary Analysis of 10 Randomized Controlled Trials Using Radiostereometric Analysis.

J Bone Joint Surg Am 2021 Oct 14. Epub 2021 Oct 14.

Department of Biomedical Data Sciences, Leiden University Medical Center, Leiden, the Netherlands.

Background: Orthopaedic surgeons aim for mechanical alignment when performing total knee arthroplasty (TKA) as malalignment is associated with loosening. Loosening may be predicted by migration as measured with radiostereometric analysis (RSA), but previous RSA studies on postoperative alignment have shown contradictory results and have been limited to cemented implants and small numbers of patients. Therefore, we performed a secondary analysis of 10 previously published randomized controlled trials (RCTs) to compare migration between postoperative in-range and out-of-range cemented and uncemented TKA implants among patients with a preoperative varus or valgus knee.

Inflammatory Bowel Diseases Increase the Risk of Periprosthetic Joint Infection.

J Bone Joint Surg Am 2021 Oct 14. Epub 2021 Oct 14.

Rothman Orthopaedic Institute, Thomas Jefferson University, Philadelphia, Pennsylvania.

Background: A large body of evidence is emerging to implicate that dysregulation of the gut microbiome (dysbiosis) increases the risk of surgical site infections. Gut dysbiosis is known to occur in patients with inflammatory bowel disease (IBD), allowing for translocation of bacteria across the inflamed and highly permeable intestinal mucosal wall. The null hypothesis was that IBD was not associated with an increased risk of periprosthetic joint infection (PJI) after primary total hip and knee arthroplasty. Read More

Neurologic Dysfunction Associated With Mechanically Assisted Crevice Corrosion and Elevated Cobalt Ion Levels After Total Hip Arthroplasty.

Arthroplast Today 2021 Oct 7;11:217-221. Epub 2021 Oct 7.

Department of Orthopaedic Surgery, UCSF School of Medicine, San Francisco, CA, USA.

Adverse local tissue reactions secondary to mechanically assisted crevice corrosion (MACC) at the trunnion is a complication of total hip arthroplasty known to cause local soft-tissue damage. However, what is not as well appreciated is that MACC in metal-on-polyethylene (MOP) articulations can lead to cobalt ion serum elevations with associated neurological dysfunction just as in metal-on-metal articulations. We report a compelling case for the association of neurologic dysfunction tied to metal ion elevations secondary to MACC at two distinct MOP tapers in a 58-year-old intensive care unit nurse with two hips implanted 3 years apart.
