Mr Kosuge is pleased to report his latest patient outcomes following knee replacement surgery at Rivers Hospital, Sawbridgeworth.

The Oxford Knee Score is based on 12 questions that patients are asked that relate to pain and function of their knee. The lowest score is 12 (indicating immense pain and poor function) and the highest score is 48 (indicating no pain and excellent function). It is a tool that is used to assess patient symptoms and is now commonly used as one of many ways to assess outcomes after knee replacement surgery.

Patients who have undergone a total knee replacement by Mr Kosuge at Rivers Hospital have an average Oxford Knee Score of 39.81 at six-months post-operation. This is based on a response rate of 65.4% of patients who were sent the questionnaires, in keeping with what one would expect in terms of response rates. This is above the national average of 36.03 at six-months after a knee replacement.

If you have arthritis in your knee, Mr Kosuge would be delighted to make an assessment and discuss management options with you. To book an appointment to see Mr Kosuge:

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.
