Objective:To investigate the effects of arthroscopic meniscus suturing on pain indicators and knee joint function in patients with meniscus injury.Methods:A retrospective analysis was conducted on the clinical data of 132 patients with meniscus injury admitted to the Linhai Second People's Hospital from January 2021 to June 2024. Based on different surgical methods, the patients were divided into two groups: the resection group ( n = 66) undergoing arthroscopic meniscectomy and the suture group ( n = 66) undergoing arthroscopic meniscus suturing. The Visual Analogue Scale scores of both groups were compared at 1, 3, and 5 days after surgery. Postoperative complications were also compared between the two groups. The levels of inflammatory factors, including interleukin-1β, interleukin-6, and tumor necrosis factor-α, were compared between the two groups before surgery and 1 week after surgery. Additionally, the knee joint range of motion and the Lysholm knee score were compared between the two groups before surgery and 3 months after surgery. Results:At 1, 3, and 5 days after surgery, the Visual Analogue Scale scores for patients in the suture group were (3.85 ± 0.43), (1.85 ± 0.29), and (0.85 ± 0.10), respectively, all of which were significantly lower than those in the resection group [(4.23 ± 0.23), (2.12 ± 0.34), (1.15 ± 0.25), t = 6.33, 4.91, 9.05, all P < 0.001]. There was no significant difference in the incidence of postoperative complications between the suture and resection groups [3.03% (2/66) vs. 1.52% (1/66), χ2 = 0.0, P = 1.000]. At 1 week after surgery, the levels of interleukin-1 β, interleukin-6, and tumor necrosis factor-α in the suture group were (0.15 ± 0.01) ng/L, (5.15 ± 0.38) ng/L, and (5.72 ± 0.59) ng/L, respectively. The values were significantly lower than those in the resection group [(0.17 ± 0.0) ng/L, (5.55 ± 0.56) ng/L, (6.10 ± 0.66) ng/L, t = 7.27, 4.80, 3.49, all P < 0.001]. At 3 months after surgery, the Lysholm knee scores and knee joint range of motion for patients in the suture group were (86.73 ± 2.85) and (126.52 ± 4.29)°, respectively. These values were significantly higher than those in the resection group [(84.15 ± 3.92), (120.65 ± 4.52)°, t = 4.33, 7.65, both P < 0.001]. Conclusions:Arthroscopic meniscus suturing causes less damage compared with arthroscopic meniscectomy. Patients undergoing meniscus suturing experience less postoperative pain, a milder inflammatory response, faster recovery, better restoration of knee joint function, and fewer complications, making the procedure safer and more reliable.
