Myocardial Injury in Patients with Hip Fracture: A HIP ATTACK Randomized Trial Substudy

Borges FK, Guerra-Farfan E, Bhandari M, Patel A, Slobogean G, Watts E, et al. (HIP ATTACK Investigators)

Journal of Bone and Joint Surgery Am. 2024 Dec 18;106(24):2303–2312. doi: 10.2106/JBJS.23.01459

Post-hoc analysis of 1,392 patients from the HIP ATTACK randomized trial examining the prevalence and prognostic significance of myocardial injury on presentation with hip fracture. Found that one in five patients presented with myocardial injury, and that accelerated surgery was associated with lower mortality in this subgroup.

Accelerated Surgery Versus Standard Care in Hip Fracture (HIP ATTACK): An International, Randomised, Controlled Trial

HIP ATTACK Investigators (including Watts E, Markham Stouffville Hospital site)

The Lancet. 2020 Feb 29;395(10225):698–708. doi: 10.1016/S0140-6736(20)30058-1

Landmark international RCT conducted across 69 hospitals in 17 countries (n = 2,970 patients), investigating whether accelerated surgery (goal: within 6 hours of diagnosis) compared to standard care reduces mortality and major complications in patients aged ≥45 with hip fracture. Dr. Watts served as a site investigator at Markham Stouffville Hospital.

Revision Total Knee Arthroplasty for the Management of Periprosthetic Fractures

Kuzyk PRT, Watts E, Backstein D

Journal of the American Academy of Orthopaedic Surgeons (JAAOS). 2017;25(9):624–633. doi: 10.5435/JAAOS-D-15-00680

Comprehensive review of surgical strategies for periprosthetic fractures following total knee arthroplasty — one of the most technically demanding scenarios in reconstructive orthopaedics. Covers patient risk stratification, fracture classification (distal femur, proximal tibia, patella), and management options including bone stock reconstruction with augments, metal cones, and endoprosthetic replacement.

Anabolic Steroids in Patients Undergoing Total Knee Arthroplasty

Metcalfe D, Watts E, Masters JP, Smith N

BMJ Open. 2012;2(5):e001435. doi: 10.1136/bmjopen-2012-001435

Systematic review of all clinical evidence for anabolic-androgenic steroids (AAS) as a rehabilitation adjunct following total knee replacement. Searched MEDLINE, EMBASE, AMED, CINAHL, and Cochrane. Found limited but positive pilot data suggesting AAS may improve quadriceps strength and functional scores, warranting a powered randomised trial.

Orthopaedic Trauma Association (OTA) — Resident Research Grant

What is the Effect of Antibiotic-Impregnated Bone Cement Spacers in the Healing Process of Large Bone Defects?

Role: Principal Investigator

Co-PI: Dr. Emil Schemitsch, MD, FRCSC

Amount Awarded: $20,000 USD

Preclinical research investigating the dose-response relationship between antibiotic-impregnated bone cement (using the Masquelet induced membrane technique) and the formation and biological activity of the induced membrane, as well as overall bone healing. Compared vancomycin and tobramycin at high and low doses against antibiotic-free controls in a rat femoral segmental defect model.
