Purposes To identify the factors that influence the recovery of physical function after unilateral total knee arthroplasty (TKA) in middle-aged and elderly patients with osteoarthritis. Methods A cross-sectional study design was adopted, and 101 patients who underwent unilateral TKA between September 10, 2018, and March 31, 2019, were recruited from the orthopedics ward of a regional hospital in South Taiwan as the subjects of this study. The patients were assessed preoperatively and postoperatively using the activities of daily living scale, visual analogue scale (VAS), and self-administered Western Ontario and McMaster Universities Osteoarthritis questionnaire. Results Patient age, anesthetic technique, frequency of postoperative ambulatory activity, preoperative VAS score, and preoperative ability to perform activities of daily living were identified as important predictors of postoperative recovery of physical function (F=11.791, p<0.001) and explained 56.4% of the total variance. Conclusions Bed rest for long periods with little engagement in ambulatory activities during postoperative hospitalization led to a higher tendency of prolonged knee function recovery time. Therefore, regular administration of analgesics during hospitalization is recommended, as it is significantly correlated with knee joint recovery. Engaging in ambulation and increased frequency of postoperative ambulatory activity are also recommended to promote the stabilization of knee function and increase quadriceps muscle strength, which will consequently enhance the postoperative recovery of physical function. The results of this study can serve as a reference for the provision of clinical care during the postoperative recovery period of patients after undergoing unilateral TKA. |
