Objective: While many biomechanical studies have compared various biotenodesis materials for biceps tenodesis, there is a lack of research comparing different types of interference screws. This study aimed to compare the impact of a polyether ether ketone (PEEK) forked eyelet tenodesis screw with the traditional PEEK closed eyelet whipstitching technique. The focus was on evaluating the occurrence of Popeye deformity, which is an objective predictor of a successful arthroscopic suprapectoral long head of biceps tenodesis. Methods: A retrospective analysis was conducted on patients who underwent arthroscopic rotator cuff repair and biceps tenodesis performed by a single surgeon between January 2010 and 2020 at a single center. The follow-up period was at least 1 year. Exclusion criteria included previous shoulder surgery and osteoarthritis. Patients were divided into 2 groups based on the type of tenodesis anchor used: forked eyelet tenodesis screw versus closed eyelet tenodesis screw. The occurrence of Popeye deformity was compared between the 2 groups. Results: A total of 82 patients who underwent arthroscopic rotator cuff repair and biceps tenodesis were evaluated, with a mean follow-up of 24.5 ± 4 months. The patients operated on using forked eyelet tenodesis screw were labeled as Group I (n=72) and those with traditional PEEK closed eyelet screw as Group II (n=10). There were no significant differences between the groups in terms of age (Group I: 59.4 ± 5, Group II: 58.4 ± 4, P=.896), gender (both groups predominantly male, P=.886), and body mass index (Group I: 26.7 ± 2, Group II: 27 ± 3; P=.896). The overall rate of popeye deformity in all patients was 8% (n=7). No significant difference in popeye deformity occurrence was observed between the 2 groups (Group I: 6/72 (8.3%), Group II: 1/10 (10%); P=.998). Conclusion: The incidence of Popeye deformity after arthroscopic biceps tenodesis in patients undergoing concomitant rotator cuff repair is low. The choice of fixation anchor, whether a forked eyelet or closed eyelet PEEK anchor, does not significantly influence the occurrence of Popeye deformity. Level of Evidence: Level III, Therapeutic study.
虽然许多生物力学研究比较了用于肱二头肌固定术的各种生物固定材料，但缺乏对不同类型干涉螺钉的比较研究。本研究旨在比较聚醚醚酮（PEEK）叉眼固定螺钉与传统PEEK闭眼缝合技术的影响。重点是评估“大力水手”畸形的发生率，这是关节镜下胸肌上肱二头肌长头固定术成功的客观预测指标。方法：对2010年1月至2020年在单一中心由同一外科医生进行关节镜下肩袖修复和肱二头肌固定术的患者进行回顾性分析。随访期至少为1年。排除标准包括既往肩部手术和骨关节炎。根据固定锚的类型将患者分为两组：叉眼固定螺钉组与闭眼固定螺钉组。比较两组之间“大力水手”畸形的发生率。结果：共评估了82例行关节镜下肩袖修复和肱二头肌固定术的患者，平均随访24.5±4个月。使用叉眼固定螺钉进行手术的患者标记为I组（n = 72），使用传统PEEK闭眼螺钉的患者标记为II组（n = 10）。两组在年龄（I组：59.4±5，II组：58.4±4，P = 0.896）、性别（两组均以男性为主，P = 0.886）和体重指数（I组：26.7±2，II组：27±3；P = 0.896）方面无显著差异。所有患者中“大力水手”畸形的总体发生率为8%（n = 7）。两组之间在“大力水手”畸形发生率上未观察到显著差异（I组：6/72（8.3%），II组：1/10（10%）；P = 0.998）。结论：在接受肩袖修复的患者中，关节镜下肱二头肌固定术后“大力水手”畸形的发生率较低。固定锚的选择，无论是叉眼还是闭眼PEEK锚，对“大力水手”畸形的发生没有显著影响。证据级别：III级，治疗性研究。
