Abstract
OBJECTIVES:This study examined periarticular multimodal drug injection and the use of nonsteroidal anti-inflammatory drugs for an early analgesic effect after total knee arthroplasty and total hip arthroplasty. Patient satisfaction and benefits from the treatment were also assessed.METHODS:A total of 110 patients who were scheduled to undergo total knee arthroplasty and 86 patients who were scheduled to undergo total hip arthroplasty were divided into two groups, the study group and the control group. The study group received a periarticular multimodal drug injection during surgery. The control group received an equal volume of normal saline. All patients received an analgesia pump and a moderate dose of nonsteroidal anti-inflammatory drugs. Resting and motion Numeric Rating Scale scores, the Western Ontario and McMaster Universities Arthritis Index, knee or hip joint range of motion, length of postoperative hospital stay, patient satisfaction, total nonsteroidal anti-inflammatory drug consumption and side effects were recorded.RESULTS:Both study groups exhibited significant improvement in pain Numeric Rating Scale scores during rest and exercise several days after the surgery. The range of joint motion was greater in the study group, and the length of postoperative hospital stay was shorter than that in the control group. Patients in the study group consumed fewer nonsteroidal anti-inflammatory drugs and reported greater satisfaction with surgery.CONCLUSION:Intraoperative periarticular multimodal drug injection significantly relieved pain after surgery and reduced nonsteroidal anti-inflammatory drug consumption. These patient had a better postoperative experience, including satisfaction and rehabilitation.
Highlights
Total knee arthroplasty (TKA) and total hip arthroplasty (THA) are important treatments for severe joint disease that can relieve joint pain and improve joint function
We found that Numeric Rating Scale score (NRS) scores with activity within a few days after surgery were lower in the study group than in the control group (Table 2, Figure 2)
The TKA study group showed a larger range of knee flexion within 4 days postoperatively than the control group, whereas the THA study group showed a larger range of hip flexion within 7 days postoperatively (Table 4, Figure 4)
Summary
Total knee arthroplasty (TKA) and total hip arthroplasty (THA) are important treatments for severe joint disease that can relieve joint pain and improve joint function. 90% of patients with pain and dysfunction show improvement after TKA, which improves their quality of life. Most patients (85%) are very satisfied with the curative effect of surgery and postoperative quality of life [1,2]. Postoperative pain has a harmful effect on important organs and directly affects postoperative rehabilitation exercises [3,4]. Pain after surgery increases patients’ concerns about rehabilitation exercises, which affects the rehabilitation.
