Comparative Study on Therapeutic Effect and Life Quality of Elderly Patients with Knee Osteoarthritis and Rheumatoid Arthritis After Total Knee Arthroplasty
Abstract
Objective. The purpose was to explore the therapeutic effect of total knee arthroplasty (TKA) in elderly patients with knee osteoarthritis (OA) and rheumatoid arthritis (RA), and to compare the changes in life quality of patients.
Methods. The clinical data of patients treated with TKA in our hospital from September 2016 to September 2017 were retrospectively analyzed, including 58 patients with OA and 58 patients with RA, to compare the therapeutic effect and the impact on life quality in the two groups of patients.
Results. The KSS clinical score and KSS functional score of the OA group were significantly higher than those of the RA group 12 months after operation (P<0.001). The MRMI scores after treatment in both groups were significantly higher than those before treatment, and the MRMI score of the OA group after treatment was significantly higher than that of the RA group (P<0.001). There was no significant difference in the operation time between the two groups of patients (P>0.05), and the drainage and hospitalization time of the OA group after operation were significant better that those of the RA group (P<0.05). There was no significant difference in the VAS scores between the two groups of patients before operation (P>0.05), and the VAS scores of the OA group at 1 month, 3 months and 12 months after operation were significantly lower than those of the RA group (P<0.001). The MBI and MMSE scores of the two groups after treatment were significantly better than those before treatment (P<0.001), and the MBI and MMSE scores of the OA group after treatment were significantly better than those of the RA group (P<0.001). The SAS and SDS scores after treatment in both groups were significantly lower than those before treatment (P<0.001), and the SAS and SDS scores of the OA group after treatment were significantly lower than those of the RA group (P<0.001). The total incidence of postoperative complications in the OA group was significantly lower than that in the RA group (P<0.05).
Conclusion. The therapeutic effect of TKA in OA patients is better than that in RA patients, and the life quality and knee joint recovery after operation in OA patients are significantly better than those in RA patients, with a lower complication rate.
