Study Compares Single- versus Two-stage Revision of Infected TKA

A study published online in The Journal of Arthroplasty compared single- versus two-stage revision total knee arthroplasty (TKA) for periprosthetic joint infection (PJI) Single-stage revision TKA patients (n = 44) were matched to two-stage revision TKA patients (n = 88). Preoperative patient-reported outcome measures did not largely differ between the groups; postoperatively, the single-stage revision TKA group had significantly higher Knee Injury and Osteoarthritis Outcome Score–Physical Function Short Form (SF), Physical SF 10A score, and Patient-Reported Outcomes Measurement Information System SF Physical and Mental scores. Reinfection and 90-day readmission rates did not largely differ between the groups.

Study: Effect of Cardiac Implantable Electronic Device on Cardiac Events After TJA

A study published in the July 15 issue of the Journal of the AAOS ® observed an increased risk for 90-day cardiac events after total joint arthroplasty (TJA) in patients with a history of a cardiac implantable electronic device (CIED). A total of 365 matched pairs of patients with TJA with and without a CIED were assessed. In the CIED group, there were 24 cardiac events, one death, 30 readmissions, and 39 emergency department (ED) visits. CIED patients were more likely than non-CIED patients to sustain cardiac events, but no differences were observed in mortality, readmissions, or ED visits.

Study: Do Opioid Prescribing Reductions Affect Satisfaction Surveys Following TSA?

According to a retrospective study published online in the Journal of Shoulder and Elbow Surgery, institution-wide reductions in opioid prescribing did not affect total shoulder arthroplasty (TSA) patient satisfaction on Press Ganey surveys. A total of 110 reverse TSA and 91 anatomic TSA patients were stratified into either a pre- or post-protocol group depending on whether they were treated before or after an institutional opioid reduction protocol. The average opioid prescription at discharge for the pre- and post-protocol groups was 426.3 milligram morphine equivalents (MME) and 193.8 MME, respectively; average pre- and post-protocol satisfaction with pain control was 4.71 and 4.74, respectively.

Study Reviews Thoracic Spinal Stenosis Prevalence and Characteristics

A systematic review published online in the European Spine Journal analyzed the prevalence and clinical characteristics of thoracic spinal stenosis. Studies reporting on the ossification of the posterior longitudinal ligaments (OPLL), ossification of the ligamentum flavum (OLF), and thoracic disk herniation (TDH) were included. Final analysis included 129 studies encompassing 1,935 patients; patients were diagnosed with OPLL (n = 361), OLF (n = 804), OPLL plus OLF (n = 143), and TDH (n = 627). Thoracic OPLL was more prevalent at the middle-thoracic spine (43.4 percent) and OLF at the lower-thoracic spine (63.1 percent). TDH was localized in the middle- (46.0 percent) and lower-thoracic (50.3 percent) spine.
