Abstract:

Objective　To investigate the effect of different concentrations of platelet-rich plasma combined with quadricep muscle training in cartilage repair of knee osteoarthritis. Methods　A total of 114 patients with cartilage repair of knee osteoarthritis treated in Shaanxi Rehabilitation Hospital from June 2022 to December 2023 were retrospectively selected as the study objects. According to different platelet-rich plasma concentrations, the patients were divided into three groups, 38 cases in each group. There were 23 males and 15 females in group A, aged (59.38±3.61) years, with a course of disease of (4.15±0.59) years, 22 cases of left knee and 16 cases of right knee, Kellgren-Lawrence (K-L) classification: 27 cases of grade Ⅱ and 11 cases of grade Ⅲ. There were 24 males and 14 females in group B, aged (60.11±3.64) years, with a course of disease of (4.18±0.62) years, 23 cases of left knee and 15 cases of right knee, K-L classification: 29 cases of grade Ⅱ and 9 cases of grade Ⅲ. There were 21 males and 17 females in group C, aged (59.94±3.62) years, with a course of disease of (4.17±0.60) years, 30 cases of left knee and 8 cases of right knee, K-L classification: 30 cases of grade Ⅱ and 8 cases of grade Ⅲ. All the three groups were treated with quadricep muscle training, and on the basis of this, different concentrations of platelet-rich plasma were injected into the knee joint. The platelet-rich plasma concentration in group A was 900 to 1 500×10⁹/L, 1 500 to 1 800×10⁹/L in group B, and 1 800 to 2 100×10⁹/L in group C. All the three groups were treated for 6 weeks. The knee function [Western Ontario and McMaster University Osteoarthritis Index (WMOAC)] and inflammatory factors and oxidative stress indexes [interleukin-17 (IL-17), Toll-like receptor 4 (TLR4), nitric oxide (NO), oxidized low density lipoprotein (ox-LDL), and glutathione peroxidase (GSH-Px)] before and after treatment and the occurrence of adverse reactions during treatment were compared among the 3 groups. Independent sample t test, paired t test, ANOVA, and χ² test were used. Results　After treatment, the scores of pain, limitation of daily living, and stiffness of the WMOAC in the 3 groups were lower than those before treatment (all P<0.05); the above scores of group B were lower than those of groups A and C [(6.39±1.52) points vs. (18.52±2.61) points and (18.54±2.63) points, (60.23±5.21) points vs. (79.46±7.12) points and (79.48±7.10) points. (4.32±0.61) points vs. (7.82±1.12) points and (7.85±1.14) points] (all P<0.05). After treatment, the levels of IL-17, TLR4, NO, and ox-LDL in the 3 groups were lower than those before treatment, and the GSH-Px level was higher than that before treatment (all P<0.05); the levels of IL-17, TLR4, NO, and ox-LDL in group B were lower than those in groups A and C [(3.22±0.43) ng/L vs. (4.51±0.57) ng/L and (4.53±0.59) ng/L, (9.78±1.21) μg/L vs. (13.25±1.95) μg/L and (13.27±1.97) μg/L, (83.52±6.72) μmol/L vs. (102.14±8.74) μmol/L and (102.18±8.79) μmol/L, (10.62±0.87) nmol/L vs. (12.15±1.34) nmol/L and (12.17±1.36) nmol/L], and the GSH-Px level was higher than those in groups A and C [(247.39±18.72) mg/L vs. (195.37±15.41) mg/L and (196.11±15.43) mg/L] (all P<0.05). During the treatment period, there was no statistically significant difference in the total incidence of adverse reactions among the 3 groups (P>0.05). Conclusion　Different concentrations of platelet-rich plasma combined with quadricep muscle training for cartilage repair of knee osteoarthritis can achieve good repair effects, and the treatment effect of platelet-rich plasma concentration of 1 500-1 800×10⁹/L is the best, which can reduce the patients' pain, improve the function of knee joint, reduce the levels of inflammatory factors and oxidative stress in the body, and is safe.
