Looking for runners after a total hip or total knee replacement for research [in United Kingdom only]

Hi all,

I am Bernard, a Senior Lecturer from the University of Essex in the United of Kingdom. I am conducting a piece of research on the biomechanical safety of high-impact exercises, like running, on hip and knee replacement implants. As part of this project, I want to collect high-resolution biomechanics data of various high-impact activities (running, jumping, landing from a height, various agility drills) in people who have successfully returned to high-impact sports after a total hip or total knee replacement.

A detailed set of eligibility criteria to be suitable to participate, can be found in the information sheet, but basically you must be 1) < 85 years, 2) 12 months after a total hip or total knee replacement , and 3) already returned to high-impact activities (running, tennis, etc) for 3 months.

What is involved? A single full day of biomechanics testing in our state of art laboratory, filling out questionnaires, muscle strength testing, and wearing an activity monitor for seven days at home. Full details in the information sheet below.

Location: Colchester, Essex.

Reimbursement: We will fully reimburse you for your travels (car, train, etc), and up to 2 nights of stay on our on-campus Wivenhoe Hotel, plus food during the stay. If you are staying far from Essex, travelling can be tiring and will interfere with testing. Depending on where you are travelling from, day 1 (arrival) may be a detailed briefing, day 2 will be the testing, and day 2 or 3 may be the departure.

Testing period: We plan to collect data on 20 people (10 hips and 10 knees) from September 2024 to September 2025. This means if you had a hip/knee replacement but not gone back to running yet as it is still too early, you may still be eligible later, so still do contact me.

Interested or have any questions? My full contact details are in the information sheet, but drop me an email at bl19622@essex.ac.uk . I will set up a time to have a chat over Zoom/Teams/Telephone with you to answer all your questions.

The first week: steady improvement each day

Hi all you inspiring hip runners

Here’s a slightly belated post on the first week following surg.


I am on day 6 following a THR of my left hip, and am feeling pretty good! It’s much better than I imagined 5 1/2 days ago. I just completed my longest walk so far (not quite 2km) with one crutch, and just tested walking up & down stairs and it feels almost like normal, easier than walking.

Indoors I am walking mostly without crutches, but when I feel tired I started using one.

I don’t really have pain now, but my hip has a ‘funny bone’ feel to it, and the operated leg feels longer when I walk. When I stand, though, it feels normal, so I’m hoping this is due to swelling.

Here’s how the previous 5 days went.

Day 1:

In France you must meet with the anesthesiologist a few weeks before the surgery, and to my surprise I was given the choice of general anesthesia vs radicular anesthesia + ‘sleepy gas’ – I chose the latter, to avoid the nausea.

It worked like a charm, and my head, at least, was fully alert by the time I got to the wake-up room in the early afternoon. It took my legs and especially the bladder longer to wake up!

There they hooked me up to liquid iron since my hemoglobin was low, and about an hour after surgery I was back in my room, dying for some food at last.

That evening the physio had me get up and use the crutches to walk, very gingerly, around my bed.

No dizziness, but I was surprised/alarmed at the pain. This was much worse than the permanent, dull ache that I had going into surgery! And my operated leg feels longer! Focused on tasks at hand (like getting in & out of bed) to put off panic.

I was instructed to do 10 reps of a few basic exercises every hour. I didn’t quite manage every hour, but was surprised that glute bridges were pretty painless, much better than walking.

‘How to Run with a Hip Relacement’ eBook

Hi all.
I’ve been absent from the blog for some time now, but I haven’t been idle. A foot injury has kept me from running (now much improved) so I poured my energy into writing an eBook, ‘How to Run with a Hip Replacement’.


A presumptuous title as running with a hip replacement is a tricky business and there are as many ‘right’ and ‘wrong’ approaches as there are opinions – as we all know. However I’ve taken a stab at throwing my thoughts down and put it on Amazon’s bookshelves. The 90 page eBook is available for a nominal  fee ($2.99) – I just looked and people are already purchasing it.

I’m hoping that it will let a runner or two know that all is not lost when they are told that a hip replacement is on the cards, and that they are not alone either.

I will update the contents occasionally so let me know if you would like a subject covered or something corrected. I’ve already spotted a few errors that I need to change. If you do read it and think you’d like to review it on Amazon, I’d appreciate it.

I’ve put a link to this blog in the Resources section at the back of the book, I hope you don’t mind. Now that it’s finished (whew!) I can put some writing energy into a blog or two.

Oh, you can buy the eBook through Amazon by clicking this link.

Dave – I’ve caught the running bug – my next 3 5K races 22:12, 21:26 & 20:55.

So after the Guppy Gallop I continued running 2 – 3 times a week, once with our Wednesday night running group along the beach and another couple of runs each week to try to keep fit and improve upon my time. I didn’t have a firm plan for my next race but didn’t think I would be waiting 12 months, I had never ran more than 1 race in a year. Several members of the group run races on a regular basis so they were always talking about their next race so I knew it would just be a matter of time. I had to travel to California 3 times for my work, once to Texas and a vacation back to England so I took my running shoes with me, running in the mountains or the hills of San Fran was very different than the beach and I really enjoyed the change of scenery. However either during every trip or immediately upon returning the same calf pain would attack me, similar to the pain when I started running after my hip replacement. I would be a mile or two into the run and then a sharp pain in the back center of my calf would attack me, I don’t think it was a cramp but my muscle would be solid and very tender where the pain was. Each time it would take about a week to recover and start running again, I did try wearing compression socks on the flight but that didn’t appear to make any difference. The only time since then I’ve flown and not experienced the same was later that year when I would stand up and walk about the plane as much as possible, so maybe that’s the trick.

mnirgOn July 9th, 2012 I then joined another running group, the Monday Night Interval Running Group, which was a much bigger group of about 50 runners that would run fast intervals of different lengths each week. It was good to run with a much fast group and add a different type of workout to … (Click Here to View Full Post and Comments)

Dave – 5K race, a Half Marathon (by accident) and a new running club

So 4 months after my hip replacement I had just completed my first 5K race in a time of 26:41 but I was beat by my 14 year old nephew who had a time of 22:17. I vowed at that time to beat him next year if they came back over from England and so my 1 year training plan began. Now I had got over the barrier of being able to complete a 5K without stopping I thought this was going to be easy, but I quickly found that running is not only a physical challenge, especially after the operation, but also a mental challenge. Running by myself along the beach, without much of a background of running and also the uncertainty of what I was going to be capable of, it’s just too easy to stop, rest and then start again. I know I should still had been glad of my accomplishment of getting out and running 3 – 4 miles a couple of times a week, I was stopping from 2 to 6 times per run and not running as fast as I did during the race. I definitely went through various emotions beginning to think I would never be able to get faster and compete, which was something I wanted to do but couldn’t while playing soccer and thought I would be able to after that. But now I was 51 and with a hip replacement and even though I had the desire didn’t feel I had the ability, I had ran a 19:12 many years earlier in one of my only handful of races so how would I ever get better.

Well my birthday wasn’t too long after the 5K race and my 3 children Sarah, Andrew and Richard clubbed together and bought me a Garmin 210 GPS watch and various running apparel. Now I could at least look and feel good even though I wasn’t running great, but I think the watch was the start of what was to come and I would recommend to everyone. Now I’m able to record all my runs, … (Click Here to View Full Post and Comments)

Alistair – Running with a hip replacement and loving it

running after a hip replacement On Christmas day 2005 I walked out of Wellington Public Hospital with a new hip replacement and no pain at last. If it wasn’t for the crutches I’d have thrown my arms in the air in celebration, just as I did finishing the Western States 100 fourteen years earlier.

Hi fellow hippies and hippies-to-be, I’m Alistair from New Zealand, “thanks” Tom for bringing us all together. I mention the WS100 mile ultra-marathon because during that last long run in 1991 my genes overtook me – Hip dysplasia, the family curse. Over the following years niggling hip pain deteriorated until I struggled to walk. You probably know the stabbing hip pain well.

After hip replacement surgery I began using trekking poles and was soon able to enjoy walking some of my old trail-running routes. I had dutifully listened to my hip surgeon who answered “No” to the inevitable question “Will I be able to run after a hip replacement?”.

Running after hip replacement surgery in Belmont Regional ParkOne day though, about 5 years post-surgery, an old urge sneaked up on me. As I began my walk up Belmont Trig I leaned forward on my toes and started to run up the steep gravel track. My hip felt strong and it seemed such a natural thing to do. Since then I have spent many happy miles playing with and researching safe running techniques and learned a lot about running with a hip replacement, and myself.

My weekend runs range from two to five hours, although I have to sheepishly admit to injuring my right foot on a tough bush run about 5 weeks ago. It’s healing but, as I sit contemplating my unused running gear, I am reminded once again not to take running for granted.… (Click Here to View Full Post and Comments)
