Hey Brian,
I personally haven't heard of any specific sporting restrictions that are specified by most of the surgeons on here. I don't know, perhaps there are some, for example competitive tackle football or extreme gymnastics (though I haven't heard these restrictions yet). When I was doing my research, I recall a claim made by Dr. Su (one of the best HR surgeons in the world). Here is what he said:
I am often asked by patients what sorts of activities they may expect to do after a hip resurfacing. To this, I am happy to respond, “EVERYTHING!” Of course, each patient and each hip situation is different, but the entire purpose of going through with the operation is to get back to doing the activities that you love doing. Once the healing process has occurred and the bone around the implants has strengthened, I release you from all restrictions. I have many patients who are martial artists, dancers, yoga practioners (sic), swimmers, cyclists and weight lifters. Many patients play competitive tennis, soccer, squash, racquetball, basketball, and volleyball. My most active patients are triathletes and marathoners…
Of course, as John C recommended, you should definitely get your surgeon's input on this. I've heard individuals come back to some very high-impact sports which place heavy loads on the hip joints (martial arts, weight-lifting, long distance running, skiing, ...) without any issues. In terms of device longevity, the long-term statistics are not in abundance at this time, as there are far more patients who have had HR procedures within the last 10 years. However, the future seems bright as most patients devices are still viable 15-20 years out.
I had bilateral HR surgeries two years ago (Dr. Gross). Beach volleyball was the primary sport I wanted to return to. And I was playing 6 months after my surgeries - it was great! It took another 3-5 months to feel like I was close to 100% recovered. I play at least once per week now, and I have zero issues or problems. Get yourself a competent surgeon and go for it!
