Infiltration is one of the treatment options for lateral epicondylosis, a degenerative process in the tendon of the musculus extensor carpi radialis brevis. The aim of this study was to evaluate the clinical outcome of a standardised fenestration technique, the Instant Tennis Elbow Cure (ITEC) technique, with injection of betamethasone versus autologous blood. A prospective comparative study was performed. Twenty-eight patients received an infiltration with 1 mL betamethasone, in combination with 1 mL 2% lidocaine. Twenty-eight patients received an infiltration with 2 mL autologous blood. Both infiltrations were administered using the ITEC-technique. The patients were evaluated at baseline, 6 weeks, 3 months and 6 months using Visual Analogue Scale (VAS), Patient-Rated Tennis Elbow Evaluation (PRTEE) and Nirschl staging. At the 6-week follow-up, the corticosteroid group showed significantly better results for VAS. At the 3-month follow-up, no significant differences were observed for all three scores. At the 6-monthfollow-up, the autologous blood group showed significantly better results for all three scores. Standardised fenestration using the ITEC-technique with corticosteroid infiltration is more effective in reducing pain at the 6-week follow-up. At the 6-month follow-up, the use of autologous blood is more effective in pain reduction and functional recovery. Level II.
渗透是治疗外侧上髁炎（桡侧腕短伸肌腱的退行性病变）的治疗选择之一。本研究旨在评估标准化开窗技术（即时网球肘治疗（ITEC）技术）联合倍他米松注射与自体血注射的临床疗效。进行了一项前瞻性比较研究。28 名患者接受了 1 mL 倍他米松和 1 mL 2%利多卡因联合浸润治疗，28 名患者接受了 2 mL 自体血浸润治疗。两种浸润均采用 ITEC 技术进行。患者在基线、6 周、3 个月和 6 个月时使用视觉模拟量表（VAS）、患者自评网球肘评估（PRTEE）和 Nirschl 分期进行评估。在 6 周随访时，皮质类固醇组的 VAS 评分显著更好。在 3 个月随访时，所有三个评分均无显著差异。在 6 个月随访时，自体血组在所有三个评分中均显示出显著更好的结果。使用 ITEC 技术进行标准化开窗，并进行皮质类固醇浸润，在 6 周随访时可更有效地减轻疼痛。在 6 个月随访时，使用自体血在减轻疼痛和功能恢复方面更有效。Ⅱ级。
