Objective To investigate the clinical effect and prognosis of cystic fluid aspiration plus intra-articular injection of triamcinolone acetonide acetate and sodium hyaluronate on Becker's cyst, and to investigate effects on serum inflammatory factors and bone metabolism of patients with Becker's cyst. Methods A total of 120 patients with Becker's cyst treated in the 900th Hospital of the Joint Logistics Support Force PLA from May 2018 to June 2020 were selected as the research objects for prospective randomized control trial (RCT), the patients were randomly divided into control group and experimental group, with 60 cases in each group. The patients in the control group were treated with traditional open surgery, with S-line incision to remove the cyst fromthe root. The patients in the experimental group were treated with cystic fluid aspiration and intra-articular injection of triamcinolone acetonide acetate and sodium hyaluronate. Under lidocaine infiltration anesthesia, one end of the shallowest cyst was selected for puncture and the cyst fluid was removed. Extract it and clean the cystic cavity with 0.9% sodium chloride solution until the flushing liquid becomes clear. Without pulling out the needle, inject 20 mg triamcinolone acetonide acetate injection and 2 mL 1% sodium hyaluronate injection into the articular cavity, bind and fix the knee joint and keep braking for 48 hours. Once a week for five weeks. The clinical efficacy and recurrence rate of the two groups were compared. The changes of visual analog (VAS) score, Lysholm score of knee joint, serum inflammatory factors and bone metabolism indexes were compared between the two groups before and after treatment, and the complications of the two groups were recorded. Results The total effective rate of the experimental group (95.0%) was significantly higher than that of the control group (75.0%), the difference between the two groups was statistically significant (P < 0.05). Compared with before treatment, the VAS score of the two groups decreased significantly (P < 0.05), the Lysholm score increased significantly (P < 0.05), and the score of the experimental group improved more significantly (P < 0.05). Compared with before treatment, the serum tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-1β (IL-1β) of the two groups after treatment were decreased significantly (P < 0.05), and the levels of inflammatory factors in the experimental group decreased more significantly (P < 0.05). Compared with before treatment, the levels of β collagen degradation products (β-CTX), nuclear transcription factor κB receptor activating factor ligand (RANKL) of the two groups after treatment were decreased significantly (P < 0.05), and the levels of serum osteoprotegerin (OPG) and insulin-like growth factor-1 (IGF-1) were increased significantly (P < 0.05), and the improvement of the above indexes in the experimental group was more significant (P < 0.05). There were no complications such as nerve and vascular injury, knee infection, flap necrosis and incision cracking in both groups during follow-up. Conclusion Cystic fluid aspiration plus intra-articular injection of triamcinolone acetonide acetate and sodium hyaluronate in the treatment of Becker's cyst can effectively improve knee function, relieve pain symptoms and reduce inflammatory reaction. The curative effect is significant, and it has certain clinical application value.
