Comparison of curative effect between arthroscopic surgery and extracorporeal shock wave in the treatment of knee osteoarthritis
A total of 90 patients with knee osteoarthritis who met the inclusion criteria were selected as the research subjects. According to the different treatment methods selected by the patients, the 90 patients were divided into a shock wave group (using extracorporeal shock wave therapy) and an arthroscopy group (using arthroscopic surgery). ), 45 cases in each group, and 15 cases in each group were divided into Ⅰ, Ⅱ and Ⅲ grades according to Kellgren-Lawrecne classification (K-L classification). The shock wave group received shock wave therapy on the pain points of the affected knee, the shock wave frequency was 10 Hz, the treatment pressure was 3 bar (1 bar=100 kPa), and each pain point was impacted 2000 times, once a week, for a total of 5 times; the arthroscopy group received arthroscopy Surgical treatment. Before treatment and at 1, 3, and 6 months after treatment, the K-L grading of the two groups was assessed using Lysholm functional score, Western Ontario and McMaster University Osteoarthritis Index (WOMAC) score and visual analogy (VAS) pain score. The knee joint functional activities and pain conditions of patients with grades Ⅰ-Ⅲ were evaluated and statistically analyzed and compared. Results After treatment, the Lysholm score, WOMAC score and VAS score of shock wave group and arthroscopy group were significantly different from those before treatment (P<0.05). Compared with the arthroscopy group at the same time point, there was no significant difference (P>0.05); the shock wave group K-L grade II and III patients had better scores at each time point after treatment than the arthroscopy group (P<0.05) . Conclusion Early intervention for knee osteoarthritis is necessary; extracorporeal shock wave therapy seems to be superior to arthroscopic surgery in relieving joint pain and improving knee function in patients with grade II and III knee osteoarthritis
