I advise patients not to return to impact sport for 1 year after surgery. For those patients who want to road run, I get them running on a treadmill at 10 months post-op and they resume road running at 12 months post-op. My unit published on activity level after resurfacing some years ago in a group of patients who followed those rules. In young men with a single osteoarthritic hip resurfaced, 92 % played sport and 62 % played impact sport. The ladies were not quite as active, but you can see from the publication that they still had an impressive activity level. In the total group their 10 year implant survival is 99.8 % showing that high activity introduced at a sensible time does not deteriorate the results.
The bone is well healed at 6-12 weeks. I allow running at 6 months. I do not use cementless resurfacing. I use Smith and Nephew Birmingham hip.
I remove activity restrictions at 6 months. I would ideally like the hip resurfacing implant to last as long as possible, and I feel that repetitive running on hard surfaces may be detrimental to the implant and it’s connection with the bone. If a patient feels strongly about running, I would prefer it be done on a softer surface.
Patients have returned to such activities as: marathons, rugby, volleyball, mountain climbing, hiking, ballroom dancing, performance dance, Thai kickboxing, mixed martial arts, judo, tae kwon doe, soccer, baseball, pitching, basketball, golf, tennis, among others.
