RESEARCH PROJECT:

Title: Prehabilitation for patients undergoing hip arthroscopic surgery for Femoroacetabular Impingement syndrome- a feasibility study

Femoroacetabular impingement syndrome (FAIS), resulting from abnormal acetabular or femoral head/neck morphology is a well-known pathological entity found in young active adults. Patients with FAIS often have pain, stiffness and functional limitations. Hip arthroscopy is often recommended when conservative management has failed to address the symptoms. However, the road to recovery is often lengthy due to a multitude of factors. This study will evaluate the feasibility, suitability and acceptability of a novel prehabilitation programme within an NHS setting and inform the design of a future large-scale trial testing the effectiveness of prehabilitation in patients undergoing hip arthroscopy.

Sonia Ubong

MPHIL STUDENT

Sonia E. Ubong is currently undertaking her Master’s in Medical Sciences (Surgery) in the Division of Trauma and Orthopaedic surgery, at the University of Cambridge.

Her research is focused on investigating the relationship between Cam-type Femoroacetuabular Impingement and patients with Axial Spondylarthritis and Psoriatic Arthropathy.

Sonia was drawn to a career in Trauma and Orthopaedic surgery due to the variety in the demographic of patients and the practical nature of the speciality. Inspired by experiences as a medical student at King’s College London, Sonia recognised that although technical excellence and clinical judgment are imperative for all surgeons, a commitment to the study of fundamental pathology is essential for advancing the field of Orthopaedic Surgery. It is through this understanding that Sonia is now working on several projects at the Young Adult Hip Research group under Mr Vikas Khanduja’s guidance.


Sport has been a strong feature of Sonia’s career. She earned her Cambridge Blue in the 2022 Rugby Varsity match at Twickenham. Her keen interest in sport has ultimately led to her growing interest in orthopaedic pathologies that affect young adults.

Students being able to explore their interests in Orthopaedic surgery is extremely important to Sonia. As such, she currently sits on the British Orthopaedic Medical Society Association (BOMSA) collaborating with medical schools to enhance the student experience and exposure to Orthopaedic surgery.

Arman Memarzadeh

MBBS, FRCS (Tr and Orth), PGCME

Arman is a consultant in trauma and orthopaedics at Cambridge University Hospitals. Having completed his higher surgical training on the Cambridge rotation, he completed further fellowship training at the Fortius clinic in London, Leeds, and Oxford University Hospitals. He was also awarded a BOA travelling fellowship to visit Chicago and Philadelphia (Rothman Institute).

His clinical specialist interest is in knee surgery, sports and arthroplasty. Arman has been awarded a number of prizes, including the Trinity Cup, Cambridge Trainee of the Year and a research grant from Addenbrooke’s Charitable Trust. 

 
Arman has three children and enjoys watching, and sometimes playing, a variety of sports.
MD Summary
 
Arman took one year out of his surgical training program to start an MD research project, investigating the effect of pre-operative muscle strength on the outcomes of hip arthroscopy. The first part of the project was to validate a strength measurement protocol using an isokinetic dynamometer, according to the ‘Cambridge Protocol’. This showed high inter- and intra-observer correlation for the protocol, and was published in 2022. 
 
The second part of the project will correlate pre-operative strength with post-op outcomes; it has received ethical approval and is due to be completed by the end of 2022.

He has published over 20 articles in peer reviewed journals, with work presented at international conferences.

Sunil Kamar

Postgraduate Researcher
Mr Sunil Kumar is an Orthopaedic Surgeon with a special interest in Young Adult Hip Surgery. He completed his orthopaedic training in the East of England based around Cambridge. 

He is completing a Hip Preservation Fellow at Northumbria prior to taking up a substantive consultant position at Addenbrookes Hospital, Cambridge. 

 

Mr Sunil Kumar maintains an active academic interest in research and teaching. He is a keen educationalist and a Member of Faculty of Surgical Trainers. His interest in outcomes in young adult hip pathology led him embarking on a journey to establish core outcome set in hip preservation surgery.

Research Summary
 
Project: Core Outcome Measure in Hip Preservation Surgery 
Publishing articles on hip preservation surgery (HPS), made me aware of the usage of patient reported outcome measures (PROMs) in YAH pathologies with no consistency amongst different studies. The project plan consists of (1) Evaluating the different PROMs used in HPS via a systematic review, (2) qualitative interview of patients to get feedback regarding the outcomes relevant to those suffering from non-arthritic hip pain and (3) finally a consensus study amongst expert from around the world via a Delphi process to come to a conclusion of the core outcome set (COS) in HPS, which has the potential to become a standard for future trial in HPS.

Andronic Octavian

Postgraduate Researcher
Born and raised in Republic of Moldova, I then have pursuit my medical studies in Romania where I graduated in 2017 at the University of Medicine and Pharmacy in Iasi. After moving to Switzerland for my orthopaedic surgical training at Balgrist University Hospital in Zurich, I soon began a Ph.D. research degree under the supervision of Mr. Vikas Khanduja in Cambridge, United Kingdom. 
 
I am currently in my final year of orthopaedic training and plan to complete a Fellowship subspecialty training in Primary and Revision Hip and Knee Arthroplasty and Orthopaedic Trauma at the University of Western Australia in Perth under the supervision of Prof Piers Yates in 2023 .
 
I am pursuing my long-term goal of becoming a complete hip surgeon and am blessed to be part of the young adult hip group led by Mr. Vikas Khanduja in Cambridge, a place where the world of hip replacement is continually evolving.
 
100-word Research Summary for Ph.D. at Anglia Ruskin University:
My Ph.D. Thesis aims to investigate effective treatments and management strategies in patients with FAI and concomitant Tönnis Grade 2 or greater hip OA.  
 
We aim to perform a series of studies to elucidate the current evidence of the efficacy of all treatment types for femoroacetabular impingement and concomitant hip degeneration and then elaborate a Delphi Consensus with an international expert panel.

These projects would then constitute the evidence-based design of a subsequent randomized controlled trial that would define guidelines for the gold standard treatment approach in this patient subpopulation.

Richard Holleyman
MBBS, MSc, FRCS (Tr&Orth)

Specialty Trainee in Trauma & Orthopaedic Surgery, Health Education North-East, Newcastle upon Tyne, UK.
British Hip Society and Orthopaedic Research UK Research Fellow.
 
Richard is a registrar in Trauma & Orthopaedic surgery based in the North-East, and is currently undertaking a PhD studying outcomes following hip surgery using national datasets. Richard is privileged to have been awarded research fellowships from the Royal College of Surgeons of England (Shears Fellowship), Orthopaedic Research UK, the British Hip Society, and the National Hip Fracture Database (honorary) in support of his work.
 
He has a passion for epidemiological research and informatics, having worked extensively with large national datasets including the Non-Arthroplasty Hip Registry (NAHR, where he has helped produce the annual report since 2017), National Joint Registry (NJR), National Hip Fracture Database (NHFD), and Hospital Episode Statistics (HES). Over the last decade, Richard has developed particular expertise in the linkage and modelling of complex local and population level data for research, health surveillance, and quality improvement and has worked with, and consulted for, a number of public and private organisations.
 
Richard’s PhD encompasses analysis of outcomes following young adult hip surgery (using NAHR data), hip fracture surgery (using NHFD data) and now, as part of a recently awarded fellowship co-funded by the British Hip Society and Orthopaedic Research UK, he is working with the research committee to examine the outcomes following complex hip arthroplasty (particularly revision/re-do surgery) and their determinants using linked data from the NJR and NHS Digital (Hospital Episode Statistics).
