Welcome to



Most cases of hip pain in adults are caused by osteoarthritis.

This is the most common type of arthritis in the UK.


The treatment of an arthritic hip is made after a discussion between the patient and surgeon.
I will discuss the alternatives to surgery with you, as well as the potential risks and benefits of an operation.

About us

Mr Alun John,
Consultant Orthopaedic Surgeon

I am a native of Llandeilo and a welsh speaker. I attended the Medical School of St Bartholomew’s Hospital in London. My orthopaedic training was undertaken in Wales and Australia.

Since being appointed as a consultant in Cardiff University Hospitals twenty yeas ago I have specialised in hip replacement surgery and I now perform up to 300 hundred primary and revision hip replacement operations a year. 


What our Patients say

My initial consultation with Mr Alun John was in February. He heard me out as to how my deteriorating hip was causing increasing pain and affecting my mobility and well-being. The hip, according to him was severely arthritic and we agreed upon a date for a hip replacement in April. He fully explained what the operation entailed. The original date had to be cancelled due to the Covid pandemic. Mr John took the trouble to get in touch with me personally and relay the bad news, promising he would get in touch as soon as the situation improved. True to his word, he contacted me mid July and offered a new date. The operation was successfully performed in early August. I am now pain free and increasingly mobile. During my stay in hospital and the subsequent follow-up appointment I was impressed by his calm and professional approach. Under his initial gruff exterior there is a kindness and a genuine care for the patient.

Mr John was recommended to me by another consultant due to his expertise in complex hip replacement operations. I have found Mr John to be both knowledgeable and professional throughout both my complicated total hip replacement procedures. He has put myself and my family at ease throughout and has been extremely helpful and efficient in dealing with any enquiry or problem. I would highly recommend him to others and have already done so.
