Effectiveness of Needle Aspiration versus Surgical Excision for Symptomatic Synovial Cysts of the Hip: A Single-Center, Retrospective Study
MEDICAL SCIENCE MONITOR(2023)
Abstract
Background: This study was performed to evaluate the clinical effectiveness of needle aspiration vs surgical excision for symptomatic synovial cysts of the hip.Material/Methods: This retrospective study analyzed the clinical data of patients diagnosed with synovial cysts of the hip and treated in a single-center hospital from January 2012 to April 2022. Patients receiving needle aspiration were assigned to group A and those treated with surgery were assigned to group B. Demographic characteristics, etiology, symptoms, cyst location, postoperative complications and recurrence, Harris Hip Score (HHS) and Visual Analog Scale of Pain (VAS) scores before treatment and at 3, 6, and 12 months after treatment were recorded to assess hip function in both groups.Results: This study recruited 44 patients, with 18 patients in group A and 26 in group B, and the 2 arms were well-balanced in terms of baseline patient profiles. Needle aspiration resulted in significantly better pain mitigation for patients at 24 h, 48 h, and 72 h after treatment vs surgical interventions (P<0.05). Needle joint aspiration resulted in significantly better function restoration of the hip joint than surgery at 3 months after treatment, as evidenced by the lower HHS score of 85.31 & PLUSMN;13.16 in group A vs 78.51 & PLUSMN;11.66 in group B (P=0.002). Surgery was associated with a significantly lower incidence of disease relapse (0.00%) vs needle aspiration (27.7%) (P=0.004). Conclusions: Needle aspiration in the treatment of symptomatic synovial cysts of the hip causes less damage to the soft tissue and leads to faster recovery in the short term than surgical resection. Surgical resection has a lower recurrence rate and better long-term efficacy.
