Abstract

Abstract:

BACKGROUND: The number of total knee arthroplasty has exceeded that of total hip arthroplasty, however, there are fewer cases receiving total knee arthroplasty in China. This discrepancy can be explained by the uncertain attitude of patients towards the efficacy of total knee arthroplasty. More studies are needed to explore the clinical efficacy and related influencing factors.

OBJECTIVE: To investigate the changes of knee function and its influencing factors after total knee arthroplasty in aged patients with osteoarthritis.

METHODS: 60 patients with osteoarthritis were treated with total knee arthroplasty surgery and rehabilitation training in Anshan Central Hospital from August 2012 to May 2014. The patient’s age, weight, height, body mass index, muscle strength, VAS score, HSS score, ROM before and after total knee arthroplasty surgery, as well as early postoperative application of CPM were recorded. The correlation between postoperative HSS score and other factors was analyzed with Pearson correlation method.

RESULTS AND CONCLUSION: The postoperative HSS score and ROM [87.3±5.5, (98.4±7.9)°] were significantly higher than those before surgery [45.8±5.7, (66.5±4.3)°, P < 0.05]. The postoperative HSS score was negatively correlated with preoperative VAS scores, preoperative HSS scores, preoperative ROM, and early postoperative application of CPM (P < 0.05). Total knee arthroplasty has an important treatment value of aged patients with osteoarthritis and can significantly improve joint function of patients. At the same time preoperative knee pain score, preoperative HSS score, preoperative ROM and early postoperative CPM application will influence the treatment effect.
