Abstract
Objective: Osteoarthritis is a chronic progressive disease that can be treated with several conservative and surgical methods. One commonly used surgical method is total knee arthroplasty. However, some patients have persistent annoying pain afterward. The aim of our study was to investigate the effectiveness of radiofrequency treatment accompanied by fluoroscopy in patients who underwent total knee arthroplasty and had no other reason for their persistent pain. Material and methods: Twenty-eight patients who had undergone total knee arthroplasty for osteoarthritis were retrospectively analyzed and included in the study. Patients who are dissatisfied after total knee arthroplasty procedure, were performed radiofrequency ablation by fluoroscopy. All patients were examined in terms of visual analog scale (VAS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores preoperatively and 2 weeks and 1 and 3 months postoperatively. Results: The VAS and WOMAC scores at postoperative week 2 and months 1 and 3 were statistically significantly different than the preoperative values for all patients (P=0.001). Conclusion: Patients with persistent pain after total knee arthroplasty obtained good results in terms of pain and knee function after conventional radiofrequency ablation accompanied by fluoroscopy but more studies with more patients are needed.
Highlights
Among the types of chronic arthritis, osteoarthritis is one of the most common complaints at admission to a hospital or a visit to an outpatient orthopedics and pain clinic
The study included 28 patients who had previously visited our clinic for osteoarthritis, did not respond to conservative treatment, had a total knee arthroplasty, and still had persistent pain
Our study of patients who underwent total knee arthroplasty for osteoarthritis showed that RF can be used as an alternative treatment in these patients who have persistent pain after surgery
Summary
Among the types of chronic arthritis, osteoarthritis is one of the most common complaints at admission to a hospital or a visit to an outpatient orthopedics and pain clinic. This condition, which restricts a patient from performing the activities of daily living and impairs the quality of life, causes irreversible joint damage. Patients visit the clinic with complaints of limited ability to move, muscle weakness, and even the inability to walk. All these conditions can prevent a patient from walking, climbing stairs, or even sitting [2]
