I had a hip replacement 4 yrs. ago, had a P/T come to my house briefly. I did the exercises faithfully and work out 3x wk. plus walk 4-5x wk. I have had tendinitis (originally diagnosed as bursitis) off and on for the past 2 years for which I went to P/T. I had a steroid shot which did not help but I find the exercise machines I use at my gym help the most. I continue to play golf 3x wk. and the tendinitis is no longer a problem.
