I had my right hip replaced in 2021. At that time the surgeon said no running or impact sports. He has since retired and I just had my left hip replaced by his protege. Both hips are same make and model, but the new surgeon said I can do whatever I want after I recover. Both surgeons are excellent, only work on hips and knees, and do a bunch of research, writing, lecturing on hips and knees. They know what's up when it comes to joint replacement. The guy who did my right hip was doing 500 joints per year. My new surgeon is doing 800 joints per year. So, why the different advice? The new surgeon said that the old surgeon was a little "old school" with his advice because he was around long enough to have installed some of the earlier generation materials. Back then they hoped to get 20 years out of hip, so the advice was based on a desire to minimize wear of the plastic component. Once the liner wears out the risk of dislocating the hip gets pretty high. I was told that the latest generation of plastic used in the acetabular cup liners shows very little wear and that they are expected to last much longer, but it will take decades for the data to develop. Also, if you are able to wear one out, and assuming the stem and cup are still well seated, an anterior approach revision to replace the plastic liner is supposed to be a "pretty easy" surgery.
