Abstract:
Objective:To explore the effect of preoperative intensive functional training on the balance and functional recovery of patients with knee osteoarthritis (KOA) receiving total knee arthroplasty (TKA).Methods:Sixty KOA patients were randomly divided into an outpatient group, a home-based group and a control group, each of 20. Before their TKAs, both the outpatient and home-based groups underwent intensive functional training for 4 weeks, while the control group did nothing special. After the TKA, all received 4 weeks of standardized postoperative rehabilitation training. Before any training, after the 4 weeks of preoperative training and 4 weeks after the TKAs, all of the subjects performed the timed up and go test (TUGT), and their joint range of motion (ROM) was recorded. They also completed the 30-second chair stand strength test (30sCST), and the 6-minute walk exercise endurance test (6MWT). KOA osteoarthritis indices (WOMACs) were also recorded.Results:After the 4 weeks of preoperative training, significant differences were observed in the trajectory length, elliptical area and TUGT times of both the outpatient and home-based groups. Four weeks after the TKAs, significant differences were observed in all of the measurements in all three groups, but the results of the outpatient and home-based groups were significantly better than those of the control group, on average. After the 4 weeks of postoperative training, there were significant differences between the outpatient and home-based groups in terms of the average knee flexion angle, knee extension angle, 30sCST and 6MWT results. There were significant differences among the 3 groups in all of the measurements 4 weeks after the TKAs, with those of the two training groups showing significantly better results than the control group. The pain scores, stiffness scores, function scores and total WOMAC scores had improved significantly compared with the control group, but the average function and total WOMAC scores of the outpatient group (24.25±2.38) and (35.41±3.02) were then significantly superior to the home-based group′s averages.Conclusions:Intensive preoperative functional training conducted in an outpatient clinic or at home can significantly improve the balance, lower limb strength, exercise endurance and symptoms of KOA patients after TKA.
