Ottawa Researcher Lands $2M to Tackle One of Orthopedic Surgery's Toughest Challenges
Ottawa orthopedic surgeon Dr. Hesham Abdelbary has received a major boost in his fight against one of the most devastating complications in joint replacement surgery — prosthetic joint infections (PJIs). The Ontario Research Fund has awarded Dr. Abdelbary $2 million to support his groundbreaking research at The Ottawa Hospital, cementing the capital's reputation as a hub for world-class medical innovation.
Prosthetic joint infections are rare but catastrophic. When bacteria colonize an artificial hip or knee, the consequences for patients can be severe: multiple surgeries, prolonged hospital stays, long-term antibiotic treatment, and in some cases, permanent disability. Despite advances in surgical technique, PJIs remain notoriously difficult to treat, and existing approaches don't work for everyone.
What the Research Aims to Solve
Dr. Abdelbary's work focuses on developing better strategies to diagnose, treat, and ultimately prevent these infections. Biofilm — the protective layer bacteria form around implants — is a key target. Once bacteria establish a biofilm on a prosthetic surface, they become highly resistant to standard antibiotics, making infections stubborn and recurring.
The $2 million Ontario Research Fund grant will allow his team to investigate novel approaches, including new biomaterials and treatment protocols that could disrupt biofilm formation and give patients a better shot at keeping their implants.
Why This Matters for Ottawa Patients
Joint replacement surgery is among the most commonly performed procedures in Canada, with tens of thousands of hip and knee replacements carried out each year. As Ottawa's population ages, demand for these surgeries is only expected to grow — and with it, the number of patients at risk for PJIs.
For patients who do develop an infection, the road to recovery is long and difficult. Many require a two-stage revision surgery, where the infected implant is removed, a temporary spacer is inserted, and a new implant is placed months later after the infection is cleared. Research that could improve treatment or prevent infection entirely would have a significant impact on the quality of life of Ottawa residents.
Recognition for Ottawa's Medical Research Community
The Ontario Research Fund grant is a competitive award designed to support high-impact scientific research with real-world applications. Dr. Abdelbary's success in securing this level of funding speaks to the strength of Ottawa's research ecosystem, anchored by The Ottawa Hospital, the Ottawa Hospital Research Institute, and the University of Ottawa.
The capital has increasingly become a destination for leading clinician-researchers, and investments like this one help attract and retain top talent that directly benefits patients in the region.
Looking Ahead
With $2 million and the resources of one of Canada's leading academic health centres behind him, Dr. Abdelbary's research has the potential to change how prosthetic joint infections are managed not just in Ottawa, but across the country and beyond. Results from this work could eventually translate into new clinical guidelines, improved implant materials, and better outcomes for the thousands of Canadians who face this difficult complication each year.
