Randomized Study: Impact of Preoperative Carbohydrate Loading on Acute TKA Outcomes
A randomized study in the June 1 issue of the Journal of the AAOS ® found that consumption of a carbohydrate-rich drink prior to total knee arthroplasty (TKA) did not improve immediate postoperative outcomes or increase risk of adverse events compared to a control group. In total, 153 patients received either a carbohydrate-rich drink, a placebo drink, or no drink prior to TKA. Postoperative pain, nausea/vomiting, and length of stay were similar overall. No patients in the intervention group were readmitted within 90 days, compared with 5.9 percent of the placebo group and 11.5 percent of the control group.

Survivorship after Aseptic Failure of a Tapered-wedge Cementless Femoral Stem in THA
A retrospective study published in the May 18 issue of the Journal of Bone & Joint Surgery reported “excellent” survivorship at a mean of 11.3 years after aseptic revision of a tapered-wedge, cementless, metaphyseal-coated femoral stem in total hip arthroplasty (THA). In total, 2,609 patients were included. The cumulative survival rate was 95.5 percent and 107 patients required revision. Loosening of the femoral component was the most common cause of aseptic failure, occurring in 33 patients (1.3 percent of the total cohort). Smaller femoral size and larger femoral head offset were associated with failure.

| Study: Postoperative Rotation and ROM in Total Shoulder Arthroplasty with LTO or Subscapularis Peel
In total shoulder arthroplasty patients, there were no differences in postoperative functional internal rotation and range of motion (ROM) between the use of a lesser tuberosity osteotomy (LTO) or a subscapularis peel to mobilize the subscapularis tendon, according to a retrospective study published online in the Journal of Shoulder and Elbow Surgery. The study included 563 patients with a minimum follow-up of two years. The peel group demonstrated greater improvement in Simple Shoulder Test scores compared with the LTO group, but this difference did not reach clinical significance.

| Systematic Review Identifies Various Methods of Quantifying Blood Loss during Trauma Surgery
A systematic review published online in the Journal of Orthopaedic Trauma identified eleven different methods of quantifying intraoperative blood loss in orthopaedic trauma surgery: six unique formulas, changes in hemoglobin and hematocrit levels, measured suction volume and weighed surgical gauze, transfusion quantification, cell salvage volumes, and hematoma evacuation frequency. The researchers queried three major databases and identified English-language orthopaedic articles published since 2010 that described methods of determining blood loss. The Gross equation was the most used formula (25 percent).

| Atypical Lower Limb Mechanics during Stair Descent after ACL Reconstruction
A study published online in the American Journal of Sports Medicine found differences in lower limb mechanics during weight acceptance in stair descent at different timepoints after unilateral ACL reconstruction (ACLR). Forty-nine athletes were grouped according to time post-ACLR: <6 months (early), six to 18 months (middle), and >18 months (late). Eighteen asymptomatic athletes were included as controls. Compared with controls, all ACLR groups demonstrated greater knee flexion angles and moments for both injured and noninjured legs, and each group had differences in velocities, moments, and powers in both legs.

AAOS Hosts Presentation of First Meyer Award to Reinhold Ganz, MD, at Annual Meeting
A tradition at each AAOS Annual Meeting is the President’s Symposium, spotlighting high-interest issues and cutting-edge innovations in orthopaedics. At this year’s meeting, the symposium was the setting for the first-ever Meyer Award, established by the ResOrtho Foundation to honor and commemorate Dominik C. Meyer, MD, an internationally renowned orthopaedic surgeon and researcher. The inaugural award went to Reinhold Ganz, MD, chairman emeritus at the University of Bern in Switzerland and an acclaimed innovator in hip surgery, in recognition of his groundbreaking work that led to new and less invasive approaches to treatment of osteoarthritis of the hip.

Take Part on a Key Informants Panel
AAOS is seeking volunteers to participate on a Key Informants Panel for the AAOS Management of Osteoarthritis of the Hip Clinical Practice Guideline. While not a voting member of the workgroup, a key informant would still be charged with reviewing introductory material, submitting guideline recommendation topics via survey, reviewing the PICO (Population, Intervention, Comparison, Outcome) list after it has been developed by the work group, and acting as a peer reviewer once this guideline has been developed. There are no financial conflict of interest limitations for Key Informants Panelists
