You may be experiencing some loss of strength. This happens in many patients one to two years after recovery from a total hip replacement (THR). Sometimes an exercise program is all you need. Your muscles can be tested and a specific program of exercises given for any weakness. A regular program of walking 30 minutes at your own pace each day has also been shown to help. Patients do best when they combine an exercise program with daily walking. It's a good idea to have your doctor check you over for any medical causes of this change in your function. If you get the all-clear signal make an appointment with a physical therapist for muscle testing and an exercise program. Most programs of this type can be done on your own at home.
