ObjectiveTo analyze the effects of high tibial osteotomy (HTO) combined with arthroscopy on the degree of inflammation and the gait activity indexes of patients with medial knee osteoarthritis.MethodsWe collected the records of 112 patients with medial knee osteoarthritis treated in the Department of Orthopedics of our hospital from June 2019 to June 2021. We divided the data into two groups: the control group included those of 54 patients who had received simple HTO and the observation group included those of 58 patients who had undergone HTO combined with arthroscopy. We assessed clinical efficacies, degrees of inflammation and gait activity indexes of the two groups to compare treatment outcomes.ResultsThe percentage of excellent and good outcomes in the observation group (89.66%) was significantly higher than that in the control group (66.67%; p < 0.05). One year after the operation, the serum and synovial fluid levels of interleukin-1β (IL-1β), interleukin-6 (IL-6) and interleukin-17 (IL-17) in the observation group were significantly lower than those in the control group (p < 0.05). Moreover, the double support phase was significantly lower in the observation group than in the control group, while the step length, speed and frequency were significantly higher in the observation group than in the control group (p < 0.05).ConclusionsHTO combined with Arthroscopy in patients with medial knee osteoarthritis improves the curative effect and the degree of inflammation, and it promotes the recovery of gait activity indices.Copyright: © Pakistan Journal of Medical Sciences.
