Hi Brent,
I’m in my mid-sixties and had my THR in 2016. I started running very low mileage about 4-5 months later and ran a 5 km race after about 9 months. I have continued running low mileage, about 20 km per week, usually at a pace around 5 1/2 minutes per km plus or minus (8 1/2 – 9 minutes per mile, I think). My longest run since the operation is about 12 km.
I have never had any pain in the area of the operated hip since about the 8-9 month mark, except a couple of times I experienced brief episodes of what felt like hip bursitis pain on the outside of that hip. I’m pretty active in a couple of other recreational pursuits that may be equally hard on the hip, but no pain and I’ve never felt the need to ice it. For example, last summer I was able to do a multi-day hike carrying a 35 pound pack over steep and rugged terrain for as much as 32 km in a day.
However, one thing I’ve learned from talking to other people with replaced hips is that there is a wide range of how quickly pain settles down, so I don’t think you should be discouraged that you still have some discomfort with yours at 10 months. Here’s hoping your next X-ray checks out fine and that the soreness gradually subsides.
Doug
