I had an old knee injury that was starting to be a problem and was recommended to Mr Cossey. Within less that 2 weeks I had had a consultation x-rays, and MRI and booked in for surgery a few weeks later. The day of surgery all was explained clearly by the anaesthetist and Mr Cossey. The surgery went well and I returned home the same day. The difference it has made to the way I walk and the functionality of my knee is remarkable, This is clearly your area of expertise. Thank you! Mr Cossey and the Just Knees Team take a lot of pride in providing a personalised 1st class experience from start to finish. Even the Physio is hand chosen and partners directly with Mr Cossey to continue the 1st class service with my recovery. Thanks.

HA knee injections have worked very well for me. As a result and at the age of 68, I have been able to continue regular cross country running and long distance walking. Kind regards.

In May 2023 following an MRI scan Mr Cossey recommended a Hyaluronic acid injection as a first course of treatment for severe knee pain caused by osteoarthritis. Just had third injection at six monthly intervals. I can't believe that the results have been so good. From being unable to walk any distance without acute discomfort I can now go on long countryside walks and play a full round of golf without pain. Life changing would not overstate the difference.


Spring has sprung and following the knee surgery you so expertly performed, I am bouncing about like a spring lamb on the tennis court and everywhere else. I am delighted at the outcome and very happy I had it done. I can’t even tell where you made the incision, as I told you, I've had bigger scratches pruning the roses! I am also amazed at the level of care I received from you and your team and the whole of the staff at Spire Hospital from start to finish. I don’t know how they managed to do it all for the cost of the operation which was excellent value, but the impressive efficiency of the whole process inspires confidence without ever feeling like I am being rushed through.


I visited Mr A Cossey’s one stop MRI Clinic yesterday. Very professional quick and efficient. Within less than 2hrs examined scanned and diagnosed what else could you ask for and he’s a very nice Man as well.


I can thoroughly recommend Andrew Cossey and the Team from JUST KNEES. Andrew exudes a suitable balance of optimism and pragmatism in his diagnosis and execution. Andrew is passionate about doing the very best for his patients and this shines through.


My knee suddenly locked after a brief walk following swimming in the sea. It slowly eased up over the next few days but there remained pain and discomfort and it needed addressing. I sought the best knee surgeon BUPA provided and asked for a consultation with Mr Cossey. I’d had an earlier meniscus tear and surgery with another surgeon in London. Mr Cossey was very positive and focused on getting my range of motion and exercise ability back to where it had been before my injury. He arranged a same day MRI to see what was happening in my knee, which confirmed it needed meniscus surgery. On the day of the operation, the hospital was clean and staff friendly and I was well cared for. Now at week 6 I am 98% back to normal and am starting to progress with my physio into movements I wasn't doing before my injury. I highly recommend Mr Cossey.


After tearing my ACL in 2014 I feared that my days of playing sport were over before they had really started. Thanks to Mr Cossey I was able to return to playing sport at the highest level after an ACL reconstruction and will be representing Great Britain at the upcoming World Ultimate Frisbee Championships.


My knee pain was affecting my life, sleep, sport, holidays and gardening all became difficult. After a consultation with Mr Cossey, and an MRI scan, he confirmed I needed a full knee replacement. He explained what the operation would entail and what the recovery process would involve. I opted for a nerve block so that a general anaesthetic was not needed. I was also offered a VR (virtual reality) headset which was very relaxing and made the operation seem very short. The whole treatment package was very professional and successful, and I am now doing the things I enjoy once more.
