American doubles player Bob Bryan says there are "no limitations" to what he can do, seven months after a similar hip surgery to Andy Murray's.
Murray, 31, hopes to resume his singles career and thinks it may be possible to return to the world's top 50.
Bryan, 40, is back playing with twin brother Mike, winning their 117th title as a pair in Florida last month.
"It feels way better than it did even five years ago when the hip was supposedly in great shape," Bryan said.
Former world number one Murray had the hip resurfacing operation - which keeps more of the damaged bone than a hip replacement, smoothing the ball down and covering it with a metal cap - in London on 28 January.
