AAOS Makes Strategic Investment in Biologics Research and Development

AAOS announced a strategic investment in the field of biologics this week. Over the next five years, AAOS will prioritize research and development for a biologics-focused competency within the Academy’s existing business. The focus of this effort will be to create evidence-based, unbiased information, thought-leadership, position statements, and educational content to help shape and guide orthopaedic surgeons and their patients within this space.

Study: Does Intra-articular Plus IV Tranexamic Acid Reduce Bleeding in Bilateral TKA?

According to a study published online in BMC Musculoskeletal Disorders, the addition of intra-articular tranexamic acid (TXA) to intravenous (IV) TXA did not decrease blood loss in simultaneous bilateral total knee arthroplasty (TKA) compared to IV TXA alone. A total of 77 patients (154 knees) were randomized to receive IV TXA (intra-articular placebo for each knee) or combined TXA (1,000 mg of intra-articular TXA for each knee). TXA was administered immediately preoperatively and six hours later. Perioperative blood loss until postoperative day three did not significantly differ between the IV TXA and combined TXA groups (1,067 mL versus 997 mL). No allogenic blood transfusions were performed Thrombotic event rates did not largely differ between the IV TXA and combined TXA groups (12 percent versus 9 percent).

Study Analyzes Prevalence of Hip and Groin Problems Among Hockey Players

Regardless of playing position, hockey players may be prone to problems pertaining to the hip and groin, according to a study published online in Knee Surgery, Sports Traumatology, Arthroscopy. Professional male ice hockey players (n = 329; mean age, 24 years) responded to an online survey that included questions on hip and groin problems (time loss and nontime loss) and symptom duration (zero weeks, one to six weeks, or more than six weeks) in the prior season, as well as current self-reported hip and groin function via the Copenhagen Hip and Groin Outcome Score. Responses were stratified by the player’s position: goalkeeper (n = 92), defenseman (n = 93), and forward (n = 144). Just more than half (n = 175, 53.2 percent) of players reported hip and groin problems in the previous season; 158 players (48.0 percent) reported nontime loss problems, and 97 (29.5 percent) had time loss problems. Outcomes did not largely differ based on playing position. Players with different symptom duration reported significantly different function, and players with long symptom duration were more likely to report more disability.

Study Evaluates Wrist Biomechanics after Operative Treatment of Trapeziometacarpal Osteoarthritis

A study published online in The Journal of Hand Surgery assessed wrist muscle force changes after trapeziectomy with or without ligament reconstruction and replacement. This was a cadaveric study in which cyclic wrist motions were replicated using a validated physiological wrist simulator. The muscle forces needed to move the intact wrist were compared to those needed after performing trapeziectomy, suture suspension arthroplasty, prosthetic replacement, and ligament reconstruction with tendon interposition (LRTI). Following trapeziectomy, higher abductor pollicis longus forces in flexion and higher flexor carpi radialis forces coupled with lower extensor carpi ulnaris forces in radial deviation were required. Wrist muscle forces after LRTI, compared to prosthetic replacement and ligament reconstruction, most closely mirrored those of the intact wrist in range of all simulated motions.

Study: Which Suture Material Is Superior for Use in Shoulder Arthroscopy?

A study published online in Arthroscopy compared six different suture materials used in shoulder arthroscopies. The researchers performed creep testing on Ethibond, FiberWire, FiberTape, Orthocord, Ultrabraid, and Ultratape; outcomes included specimen stiffness, initial elongation at 60 N of load, static creep, and relaxed elongation. Cyclic testing was employed to compare dynamic creep, peak-to-peak displacement, and relaxed elongation; mechanical testing was performed using a material testing machine in 37 degrees Celsius phosphate-buffered saline solution. FiberTape presented the greatest stiffness, as well as smallest amounts of static and dynamic creep and peak-to-peak displacement. The smallest initial elongation was observed in FiberTape and FiberWire, and the greatest relaxed elongation was observed in Ultrabraid.

CMS Releases Estimated Improper Payment Rates for FY 2019

The Centers for Medicare & Medicaid Services (CMS) reported decreases in improper payment rates in its Medicare Fee-for-service (FFS), Part C, and Part D programs and increases in Medicaid and the Children ‘s Health Insurance Program (CHIP) from fiscal year (FY) 2018 to FY 2019. From 2018 to 2019, annual improper payment rates changed from 8.12 percent to 7.25 percent for Medicare FFS, 8.10 percent to 7.87 percent for Part C, and 1.66 percent to 0.75 percent for Part D. Improper payment rates increased from 9.79 percent to 14.90 percent for Medicaid and 8.57 percent to 15.83 percent for CHIP. According to CMS, year-over-year comparisons may not be accurate for Medicaid and CHIP due to the reintegration of the Payment Error Rate Measurement eligibility component.

Early Career Advice from the LGBTQ Community

This article is part two of a three-part series of interviews seeking recommendations to make orthopaedics more open and inclusive. In this article, individuals in the LGBTQ (lesbian, gay, bisexual, transgender, and queer [or questioning]) community share experiences about their orthopaedic training and early careers, as well as provide advice to individuals who may be considering a career in orthopaedics but feel excluded.
