[Effect of inpatient rehabilitation measures on patients with total hip endoprostheses--evaluation 15 months after operation]

Abstract

159 patients were examined approximately 15 months after hip arthroplasty. 116 of these patients have had at that time point a postoperative 4 week hospital stay for rehabilitation. A score that considered pain at motion and at rest, maximal walking capacity and activity of daily living was used for evaluation. The preoperative conditions did not differ between patients that had their postoperative hospital stay for rehabilitation (n = 116) and those that did not (n = 43). The results at the time of examination were regarded as excellent (group 1; score 3) in 64 (40.3%) patients, as good (group 2; score 4) in 56 (35.2%) patients and as poor (group 3; score > or = 5) in 39 (24.5%) patients. The amount of patients with a hospital stay for rehabilitation was significantly (p = 0.025) higher in the patient groups with excellent or good results in comparison with the patients with poor postoperative outcome. The most excellent results were obtained in patients who had their rehabilitation within the first two months after surgery (p = 0.008). Apart from the above mentioned score the following-additionally assessed-parameters differed significantly between the 3 groups: hip mobility; pain elicited by pressure on the operated joint; pain in the contralateral hip or knee joints; consumption of analgetics; walking time for 15 meters; degree of handicap as assessed by the patient or the occupational therapist or the physician; coping with household activities (for females only). We conclude that a poor result of hip arthroplasty may be due not only to degenerative joint disease of the lower limbs but also (or in combination) to the lack of a postoperative hospital stay for rehabilitation.
