About Professor Stephen McDonnell

Stephen McDonnell is an Associate Professor at the University of Cambridge and a Consultant Knee and Hip Surgeon working at Addenbrookes Hospital. He undertook his research MD and orthopaedic surgical training in Oxford, based at the Nuffield Orthopaedic Centre. He has a specialist knee and hip "Sports and Joints" fellowship in Melbourne with the Melbourne Orthopaedic Group. He gained an extensive experience in patients with sports injuries and arthritis. He believes that each patient should be prescribed a personalised package of care and treatment program.

 I have a special interest and undertake the majority his knee replacements, partial unicompartmental knee replacements (sometimes called knee resurfacing) only replacing the damaged area of the knee, which have lower risks from surgery and can provide a superior functional outcome for patients. 

He has a keen interest in sport and has been the match orthopaedic surgeon for first-class rugby internationals, and is a regular motorsports doctor at Silverstone for the Formula One British Grand Prix.

He is heavily involved in research, education, and lectures locally, nationally and internationally. He has developed the undergraduate orthopaedic curriculum, inspiring orthopaedic medical students to be orthopaedic surgeons of the future.

The whole experience was excellent. Despite being a significant surgical procedure (total hip replacement) I found the visit stress free. The manner of both Professor McDonnell and the support offered was excellent. The 2 nights I spent in the hospital were comfortable and everything was managed in a very professional manner. Everything was clearly explained so that I knew what to expect and this was done in a way that did not create any anxiety as I was left feeling completely confident in the abilities of those involved with my operation.

Well what can I say , from start to finish (which he obviously knew the outcome) my views were listened to and everything explained. From my first visit years ago he said I needed a replacement but I wasn’t ready , so went away , then came back and had an Unloader brace . Eventually I came back and asked for the surgery. That was 3 months ago but my life has wound back at least six years !!!

Professor McDonnell replaced my right hip nearly 5 years ago and I was very happy with that experience, so when my left hip needed replacing my immediate reaction was to seek his help. The operation on this second hip went equally smoothly and he was able to answer the two minor queries I had at the follow-up appointment so that my mind was put at rest. I would not hesitate to seek his help with any other orthopedic problems.

I have really appreciated Prof. McDonnell's calm, straight forward manner and the way he communicates. He clearly did an amazing job with my knee and I am eternally grateful and looking forward to getting the second one completed.

The purpose of my partial knee replacement was to allow me to ski at a high level again. 3 months post op I am once again lifting weights and boxing. With the ski season starting 3 months from now I am confident that I will be back on the slopes and I could not be happier with the outcome.

Acl surgery with LET, the process was smooth and we took the time to plan the complication of cyclops lesion which was preventing me to get back to active sports. We've completed the removal of the cyclops lesion and other issues around the knee since it was being opened up. Overall experience was great from Stephen, Nuffield team, secratary, nurses, surgery team, physio etc... I am now kn the road to recovery, bearing weight and hope to get back to football and bjj.

Prof McDonnell was amazing. He clearly explained the procedure and I felt like I was on good hands for my surgery. This was a seamless process and I feel confident that the aftercare is still there if needed. I felt listened to and fixed within a relatively short time.
