摘要

目的：本研究调查了前交叉韧带（ACL）重建术后与膝关节旋前肌病变和膝关节伸展功能丧失有关的背景因素和骨隧道位置，以及膝关节旋前肌病变与术后肌力变化之间的关系。方法：本研究纳入了 192 例接受 ACL 双束重建术的患者（101 例男性，91 例女性，平均年龄 27.9 岁[13-70 岁]），这些患者均通过磁共振成像或第二眼关节镜评估了膝关节旋前肌病变。使用计算机断层扫描测量骨隧道位置，术后测量膝关节伸展受限情况。术前和术后测量了膝关节伸屈力量。分析了旋前肌组和无旋前肌组之间的差异。结果旋前肌病变的存在与股骨后外侧束骨隧道较浅显著相关（p = 0.03）。在存在旋前病变的情况下，前内侧束股骨骨隧道位置较高（p = 0.01）和胫骨骨隧道位置较后（p = 0.048）会导致伸展受限。旋前组和无旋前组的膝关节伸展力量在术前没有差异（p = 0.73），而术后 4、6、9、12 个月的差异（各 p < 0.05）明显更大，旋前组的数值低于无旋前组。结论骨隧道位置和移植物大小与环形病灶的形成有关，随后的伸展功能丧失和环形病灶与前交叉韧带重建一年后的伸展力量减弱有关。

Etiology and effects of cyclops lesions in double-bundle anterior cruciate ligament reconstruction: A case-control study

Purpose

This study investigated background factors and bone tunnel location related to cyclops lesions and knee extension loss after anterior cruciate ligament (ACL) reconstruction, and the relationship between cyclops lesions and postoperative muscle strength changes.

Methods

This study included 192 patients (101 male and 91 female patients, mean age of 27.9 years [range, 13–70 years]) who had undergone ACL double-bundle reconstruction and had cyclops lesions evaluated by magnetic resonance imaging or second-look arthroscopy. The bone tunnel position was measured using computed tomography, and knee extension limitation was measured postoperatively. Knee extension and flexion strength was measured preoperatively and postoperatively. Differences between the cyclops and no-cyclops groups were analyzed.

Results

The presence of cyclops lesions was significantly associated with a shallower femoral bone tunnel of the posterolateral bundle (p = 0.03). In the presence of a cyclops lesion, the higher position of the femoral bone tunnel of the anteromedial bundle (p = 0.01) and the posterior location of the tibial bone tunnel (p = 0.048) cause extension limitation. There was no difference in knee extension strength between the cyclops and no-cyclops groups preoperatively (p = 0.73), and the postoperative differences at 4, 6, 9,12 months (each p < 0.05) were significantly larger, with the cyclops group having lower values than the no-cyclops groups. There was no significant difference in knee flexion strength (p > 0.05).

Conclusion

Bone tunnel position and graft size are associated with the formation of cyclops lesions, and subsequent extension loss and cyclops lesions are related to weakness in extension strength one year after ACL reconstruction.

期刊介绍： Journal of Orthopaedics aims to be a leading journal in orthopaedics and contribute towards the improvement of quality of orthopedic health care. The journal publishes original research work and review articles related to different aspects of orthopaedics including Arthroplasty, Arthroscopy, Sports Medicine, Trauma, Spine and Spinal deformities, Pediatric orthopaedics, limb reconstruction procedures, hand surgery, and orthopaedic oncology. It also publishes articles on continuing education, health-related information, case reports and letters to the editor. It is requested to note that the journal has an international readership and all submissions should be aimed at specifying something about the setting in which the work was conducted. Authors must also provide any specific reasons for the research and also provide an elaborate description of the results.
