Can AR Be Used to Reduce Perioperative Anxiety in Patients Undergoing Surgery?


JAMA Network Open published a randomized controlled trial evaluating the use of an augmented reality (AR) walkthrough on perioperative anxiety in patients undergoing elective orthopaedic surgery. Forty-six patients experienced an AR explanation of what to expect on their day of surgery while 49 patients received standard presurgery instructions. The primary outcome was change in State-Trait Anxiety Inventory (STAI) from screening to preoperative surveys. The AR group experienced a decrease in STAI scores (−2.4) and the standard care group experienced an increase (+2.6); however, there was no significant effect on postoperative anxiety, pain levels, or narcotic use.

Study Shows Robotic-arm–assisted THA Effective for Pre- and Intraoperative Decision Making


A randomized controlled trial in the Journal of Orthopaedic Surgery and Research of 60 patients undergoing total hip arthroplasty (THA) compared the efficacy of robotic-arm–assisted THA (rTHA) to conventional THA (cTHA). Predicted and actual prosthetic size, prosthetic position, and leg length were compared between groups. Complete coincidence of predicated versus actual implant size was seen in 90 percent and 86.2 percent in the rTHA and cTHA groups, respectively. There was a significant difference in leg length between the surgical side and contralateral side between the rTHA group (0281 mm) and the cTHA group (3.79 mm).

Study: Outcomes of Quadriceps Tendon with Bone versus Hamstring Tendon Autograft after ACLR


Comparing ACL reconstruction (ACLR) using quadriceps tendon with bone (QTB) versus hamstring tendon (HT) in patients with hyperextension of the knee, a retrospective study in Arthroscopy found that QTB yielded better anterior and rotational stability. Overall, there were 42 patients in the HT group and 21 in the QTB group. Side-to-side differences (SSD) and graft intensity were compared. The median SSD in the anterior translation was 1.75 mm in the HT group and 1.0 mm in the QTB group. Additionally, the signal intensity of the graft was also improved in the QTB group.

Study Finds TXA Use Is Not Associated with Increased Risk of VTE in Trauma Patients


Injury published a study that analyzed prospective, observational data to examine the association between tranexamic acid (TXA) use and the risk of venous thromboembolism (VTE) and mortality. A total of 7,331 patients were analyzed, of which 6.4 percent received TXA. The rate of VTE was 12.5 percent in the TXA group compared with 4.6 percent in the non-TXA group. For the TXA group, the rate of mortality was 5.6 percent versus 1.7 percent in the non-TXA group. TXA use was not significantly associated with VTE; however, TXA use was found to be significantly associated with increased mortality.

Study: Union Rate after Vascularized Pronator Quadratus Pedicled Bone versus Iliac Crest Bone Grafting


A study in Current Orthopaedic Practice compared the rate of the union of iliac crest bone and vascularized pronator quadratus pedicled bone grafting to treat scaphoid nonunion. Union rate and grip strength were retrospectively collected from 23 patients in the pronator quadratus group and 31 patients in the iliac crest groups. Bony union was achieved in all patients. Grip strength of the contralateral wrist was 85.6 percent in the pronator quadratus group and 87.8 percent in the iliac crest group, respectively
