Abstract
We studied the cases of twenty-six patients (all female, age from 27 to 63 years) with osteoarthritic hips which had total hip arthroplasty (over 10 years follow-up). The correlation between hip joint function at the time of this study and post-operative patient activity were evaluated with the results as follows:
1) Younger patients tended to have lower hip joint function than older patients.
2) Patients who had a professional work also tended to have lower hip joint function than housewives.
3) There was no significant correlation between body weight and hip joint function.
4) High frequency of going up and down stairs or squatting and standing was considered to be a factor to make worse hip joint function.
5) Patients who kept on doing non-weight beared muscle strengthening exercise of hip abductors appeared to preserve good hip joint function.
These results indicate that it is important to advise patients who had total hip arthroplasty on their daily living in detail, in order to maintain good hip joint function for a long time.
