Abstract:

Objective To observe the effects of preoperative ozone injection combined with high tibial osteotomy (HTO) on joint function, gait recovery, and serum inflammatory factors in patients with knee osteoarthritis (KOA). Methods A total of 93 patients with KOA who underwent HTO in the hospital were retrospectively enrolled from March 2024 to March 2025. Based on the presence or absence of preoperative knee injection of ozone, they were divided into group A (injection, n = 47) and group B (non-injection, n = 46). The changes in joint function, including the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Hospital for Special Surgery Knee Score (HSS score), medial proximal tibial angle (MPTA), and range of motion (ROM), gait recovery (step length, walking speed, stride frequency), and serum levels of Interleukin (IL)-1β, IL-6, IL-8, and IL-10 before and after treatment were compared between the two groups. Knee pain, as measured by the visual analogue scale (VAS), was observed at 5 weeks, 1 month, and 6 months after surgery, and complications were recorded. Results At 5 weeks post-surgery, the WOMAC and MPTA in group A were lower than those in group B, whereas the HSS score and ROM were higher than those in group B (P < 0.05). In the 120-meter gait test, the step length, walking speed, and stride frequency in group A were all higher than those in group B (P < 0.05). The serum levels of IL-1β, IL-6, and IL-8 in group A were lower than those in group B, and the level of IL-10 was higher than that in group B (P < 0.05). At 5 weeks, 1 month, and 6 months post-surgery, the Visual Analog Scale (VAS) scores in group A were lower than those in group B (P < 0.05). There was no significant difference in the incidence of postoperative complications between the two groups (P > 0.05). Conclusion Intra-knee injection of ozone can effectively promote the postoperative recovery of joint function and gait, alleviate the serum inflammatory response, and relieve postoperative pain in patients with KAO before HTO.
