Application effect of arthroscopic patellofemoral joint denervation combined with high tibial osteotomy in knee osteoarthritis
From January 2019 to December 2020, 100 patients with varus medial tibiofemoral arthritis and patellofemoral arthritis who were admitted to Nanchang First Hospital were selected as the research objects. They were divided into arthroscopic group and artificial total knee replacement according to patients' wishes. operation group, 50 cases in each group. The arthroscopy group underwent arthroscopic radiofrequency denervation of the patellofemoral joint combined with high tibial osteotomy, and the total knee arthroplasty group underwent total knee arthroplasty. The operation-related conditions, Hospital for Special Surgery (HSS) knee score, Lysholm knee score, and visual analog score (VAS) were compared between the two groups at the time of discharge, and the changes in hemoglobin levels before and after surgery were compared between the two groups. Results The intraoperative blood loss in the arthroscopy group was less than that in the total knee arthroplasty group, and the difference was statistically significant (P<0.05). The operation time and postoperative hospital stay in the arthroscopy group were shorter than those in the total knee arthroplasty group, and the difference was statistically significant (P<0.05); the HSS knee score and Lysholm in the arthroscopy group The knee joint score was higher than the total knee arthroplasty group, the difference was statistically significant (P<0.05); the VAS score of the arthroscopy group was lower than the total knee arthroplasty group, the difference was statistically significant (P<0.05); The level of hemoglobin in the arthroscopy group was higher than that in the total knee arthroplasty group after surgery, and the difference was statistically significant (P<0.05). Conclusion For patients with knee osteoarthritis who need knee arthroplasty, arthroscopic radiofrequency denervation of the patellofemoral joint combined with high tibial osteotomy has less surgical trauma, quicker postoperative recovery, and can effectively improve the patient's joint function. , and less residual postoperative chronic pain
