Mr Kosuge is Principal Investigator for The Princess Alexandra Hospital NHS Trust in a national study recruiting patients with osteoarthritis of the knee. Funded by the National Institute for Health and Care Research and entitled ‘Obesity and Arthritis of the Knee Study’, the aim of the study is to qualitatively explore patients’ lived experience of knee pain and weight treatment in the NHS. In addition, it aims to explore and model which baseline or treatment factors predict knee function at 12 months after a secondary care appointment in the NHS for osteoarthritis of the knee.

Over the course of the past one-year, Mr Kosuge and the research team at The Princess Alexandra Hospital NHS Trust helped recruit patients seen in his out-patient clinic to participate in this study. In addition to recruitment from three other hospitals, the milestone of 400 patients was reached in December 2025.

The study will now follow-up these patients and is aimed for completion in 2027. Mr Kosuge is looking forward to the results with the hope that treatment of osteoarthritis in the knee, especially in the obese population, in can be improved in the future.
