Abstract
We studied changes of pain intensity and functional impairment in 22 patients with osteoarthrosis undergoing total hip replacement. Using a visual analogue scale, the mean scores for pain and disability before surgery were 71.7 and 70.9 respectively. Both scores showed gradual improvement during a 1-year follow-up period, with more than 90% of the total improvement occurring within the first 3 months. After 1 year, the scores for pain and disability were 11.9 and 4.1 respectively. The hip joint capsule was studied using immunohistochemistry to detect neurofilaments. Neurofilament immunoreactivity was observed in 16/22 cases and was correlated with pain and disability scores. However, there were no correlations between pre- and postoperative pain scores, the score changes, and the quantity of capsular neurofilaments. Thus, other factors than capsular neurofilaments influence the scores of pain and disability in osteoarthritis.
