  Bi-unicompartmental knee arthroplasty is not superior to cruciate-retaining TKA at 24 months in exploratory randomized trial
  In an exploratory randomized trial at a tertiary center in Tehran, Iran, patients with severe bicompartmental femoro-tibial osteoarthritis and intact cruciate ligaments underwent simultaneous bi-unicompartmental knee arthroplasty or cruciate-retaining total knee arthroplasty, according to the Journal of Arthroplasty. The Forgotten Joint Score at 24 months, the primary end point, did not differ significantly (mean difference -4.91 points; 95% CI -17.92 to 8.09; P = .453) in a per-protocol, complete-case analysis of 26 and 30 patients. No major complications, reoperations or revisions occurred in either group.

  Shoulder Innovations begins limited release of InSet Go glenoid implant for anatomic shoulder arthroplasty
  Shoulder Innovations said it began a limited user release of the InSet Go, its next-generation glenoid implant for anatomic shoulder arthroplasty, and that the first case was performed by Dr. Robert Gillespie. According to the company, the design imprints the implant within a circumferential rim of hard, supportive bone to eliminate the rocking horse mechanism that leads to glenoid loosening, and it reduces the surgical steps, with the potential for shorter procedure times.
