Clinical Profile

Show/hide details

Dr. Chaudhry is an orthopaedic surgeon in the Holland Bone and Joint Program with a clinical practice focused on hip and knee replacement surgery. He has a special interest in revision (i.e. re-do) surgery for failed hip/knee replacements, surgery in patients with obesity, and minimally invasive muscle-sparing approaches to hip replacement (e.g. the Direct Anterior Approach).

Dr. Chaudhry’s clinical practice philosophy is patient-centered, with the goal of personalizing each patient’s management plan through the integration of research-informed discussion and shared decision-making.

Dr. Chaudhry’s practice model is team-based—he works collectively with allied health care providers (for example, advanced practice providers), surgical trainees, medical doctors and other expert surgeons—to provide the best possible outcome and experience for all patients.

Research Summary:

Dr. Chaudhry is a researcher, a surgeon-investigator and an associate scientist in the Holland Bone and Joint Research Program at SRI. His research aims to improve clinical outcomes in patients with end-stage degenerative joint disease, with a focus on hip and knee reconstruction.

As most patients are generally very satisfied following hip and knee replacement, Dr. Chaudhry is specifically interested in identifying subgroups of patients who have relatively poor outcomes following surgery, and determining how to improve outcomes in these subgroups. These groups have included patients with high degrees of frailty, geriatric hip fracture patients, patients with cognitive impairment, and patients with severe and morbid obesity.

Dr. Chaudhry is also interested in streamlining perioperative care processes through the implementation of standardized evidence-based protocols and integration of emerging technologies.

Through formal training in health research practice, Dr. Chaudhry has acquired proficiency with cutting-edge research methods and techniques, including multinational clinical trials, large administrative database studies and network meta-analyses.
