RÉSUMÉ
Objective:To investigate the clinical efficacy of arthroscopy combined with sodium hyaluronate and platelet-rich plasma in the treatment of Stoller grade III meniscus injury.Methods:Sixty patients with Stoller grade III meniscus injury who received treatment in The Second People's Hospital of Liaocheng from October 2019 to October 2020 were included in this study. They were randomly divided into an observation group and a control group ( n = 30 per group). Patients in the observation group were treated with arthroscopy combined with sodium hyaluronate and platelet-rich plasma, while patients in the control group were treated with arthroscopy combined with sodium hyaluronate. Before and 1, 3, and 6 months after surgery, the Visual Analogue Scale (VAS) score, Lysholm score, and The Western Ontario and McMaster Universities Arthritis Index (WOMAC) score of the knee joint were compared between the two groups. Results:There were no serious complications in each group. Compared with pre-treatment, the VAS and Lysholm scores of the knee joint in both groups significantly decreased at 1, 3, and 6 months after surgery, while the WOMAC score showed a significant increase ( F = 514.96, 673.19, 96.31, 124.16, 230.99, 531.84, all P < 0.001). After 3 and 6 months of treatment, the VAS score in the observation group was (1.1 ± 0.5) points and (0.8 ± 0.4) points, respectively, which were significantly lower than (2.5 ± 0.7) points and (1.3 ± 0.5) points in the control group ( t = 8.91, 4.28, both P < 0.001). After 3 and 6 months of treatment, the Lysholm score of the knee joint in the observation group was (86.2 ± 9.1) points and (93.8 ± 13.2) points, respectively, which were significantly higher than (79.8 ± 11.3) points and (87.5 ± 9.2) points in the control group ( t = 2.42, 2.14, both P < 0.05). After 3 and 6 months of treatment, the WOMAC score in the observation group was (17.5 ± 3.6) points and (16.5 ± 3.2) points, respectively, which were significantly lower than (25.4 ± 5.2) points and (24.8 ± 6.4) points in the control group ( t = 6.84, 6.35, both P < 0.001). Conclusion:Arthroscopy combined with sodium hyaluronate and platelet-rich plasma is more effective in treating Stoller III grade meniscus injury than arthroscopy combined with sodium hyaluronate. The former therapy can be promoted in the clinic.
