Exercise may help in postponing total hip replacement surgery in patients with hip OA

Over the years, the number of patients suffering from osteoarthritis of hip has been steadily increasing. These patients ultimately require a total hip replacement surgery which may be quite expensive. A new research published in the journal Annals of the Rheumatic Diseases has found that patients who underwent an educational program and exercise reduced their need for hip replacement surgery by almost 44%.
For their research which was led by Ida C. Svege from the Oslo University, the researchers did a randomized trial exercise in 109 patients who had symptomatic and radiographically documented hip OA. The average age of the patients was 58 and almost half of them were women. At the start of the study, the patients suffered from night pain but were not candidate for hip replacement. All the participants were given three educational sessions about hip OA. Half of them were also made to undergo two to three exercise sessions every weak in order to strengthen and increase function and flexibility.
The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) was used to assess the symptoms and functional status of the hip joint. The activity of the joint was rated on the Physical Activity Scale for the Elderly (PASE). During the follow-up period of the study, 22 patients from the exercise group and 31 patients from the control group underwent hip replacement surgery. The researchers observed that the survival of the original hip was 0.41 in the exercise group compared to 0.25 in the control group after doing a Kaplan-Maier analysis.
There was a considerable difference seen in the WOMAC function of the joint in the two groups although not much difference in the degree of pain perceived by the two groups. This has made the researchers opine that the longer time to hip replacement surgery in the exercise group is because of the better joint function. Recommending regular exercises to patients suffering from hip OA may increase the survival of the original joint and reduce the need for hip replacement surgery.
