OUTCOME OF TOTAL KNEE ARTHROPLASTY IN OSTEOARTHRITIS PATIENTS AT FANG HOSPITAL, CHAING MAI PROVINCE

Abstract

ABSTRACT

BACKGROUND

                Osteoarthritis is one of the causes for disabilities and has effect to aging people’s health status. In these times, total knee replacement surgery has been a successfully way to treat patients with osteoarthritis. Treatment results of surgery come from patient’s own self-adjustment. Following up treatment after total knee replacement surgery indicates patient care quality.

OBJECTIVE

                To study total knee replacement surgery results in range of motion also studies the correlation between self-adjustment efficacies and results of total knee replacement surgery.

 METHODS

                A cross-sectional descriptive study was applied to the sample group of 87 patients with osteoarthritis who had been in the total knee replacement surgery in Fang Hospital, Chiang Mai from October 1st 2014 to September 30th 2016. Data were analyzed by Spearman’s correlation coefficient and chi-square statistics.

RESULTS

                The study found the 0-degree extension range of the undergone surgery knee’s movement as 87.4% while the 91-110 flexion as 37.9%. There were 94.3% of post-surgery patients without complications. After the operation, total self-adjustment efficacy of patients was in progress of adaptation. Physical adjustability was effective, meanwhile other three adjustability remained in progress. There were 54.02% of patients who were in progress and 45.98% were effectively adjusted. The study found positive factors effecting the after-operation adjustability were education, family income, duration after the surgery and mean knee movement. Age was a negative factor for adjustability while gender and marital status were not significantly correlated with overall patient adaptation.

CONCLUSIONS AND DISCUSSIONS

                In conclusion, negative factor effecting the treatment is age. Thus, we should support or focus more in elderly patients before the operation process. Education about osteoarthritis, surgery process, knee movement practice and daily living skills should be given to patients and their family. Family should take part in the preparation process from the beginning, in order to help patient’s acknowledgement and self-care practice after the procedure.
