PURPOSE
Reconstruction of the Anterior cruciate ligament (ACL) using tendon grafting is an established method for restoring knee function and stability. Multiple methods are established for graft fixation. Several involve anchoring the autograft distant to the joint with hardware that remains implanted. This study reports the first early to midterm results in patients who received ACL reconstruction (ACLR) using the T-Lock Osteotrans femoral near joint fixation method with a tibial fixation using the BioactIF Osteotrans interference screw.
METHODS
This consecutive prospective series included 20 Patients (14 Male, 6 Female) with a primary ACL rupture. All patients were treated with an ACLR using a semitendinosus autograft fixated with the T-Lock Osteotrans and were followed-up postoperatively. The following parameters were assessed: Side-to-side difference of the posterior-anterior translation measured using the KT-1000 arthrometer, Tegner activity score, Lysholm score, IKDC subjective knee evaluation form. Magnetic resonance imaging (MRI) was done to assess tunnel enlargement and integrity of the anchoring device.
RESULTS
The average follow-up duration was 2 years (range 1-4.2 years). One patient was lost to follow-up. Two Patients suffered a traumatic ACL re-rupture 2 years postoperatively and received a 2-stage revision ACLR. Difference in the posterior-anterior translation was 1.8 mm (range 0-5). The median Tegner score was 6 (range 4-10) and 9 patients (45%) returned to their preinjury level of activity. The mean IKDC subjective knee evaluation form scored 91 points (range 77-100). The mean Lysholm score was 86 points (74-96). All mentioned scores were significantly better compared to preoperative values. No relevant tunnel enlargement was seen on MRI. The anchoring device was evaluated to be intact in all patients.
CONCLUSION
ACLR with the aforementioned procedure leads to good clinical and radiological outcome.
目的
使用肌腱移植物重建前交叉韧带（ACL）是恢复膝关节功能和稳定性的一种成熟方法。已经建立了多种移植物固定方法。其中一些方法是使用植入物固定远离关节的自体移植物。本研究报告了使用 T-Lock Osteotrans 股骨近关节固定方法和胫骨 BioactIF Osteotrans 干扰螺钉固定进行 ACL 重建（ACLR）的患者的早期到中期结果。
方法
本连续前瞻性系列研究纳入了 20 例（14 名男性，6 名女性）初次 ACL 断裂患者。所有患者均采用半腱肌自体移植物固定的 ACLR 治疗，并用 T-Lock Osteotrans 固定，并在术后进行随访。评估以下参数：使用 KT-1000 关节测量仪测量的前后平移的侧间差异，Tegner 活动评分，Lysholm 评分，IKDC 主观膝关节评估表。进行磁共振成像（MRI）以评估隧道扩大和锚固装置的完整性。
结果
平均随访时间为 2 年（范围 1-4.2 年）。1 例患者失访。2 例患者在术后 2 年发生创伤性 ACL 再断裂，接受了 2 期 ACLR 翻修。前后平移的差异为 1.8mm（范围 0-5）。中位数 Tegner 评分为 6（范围 4-10），9 例（45%）患者恢复到受伤前的活动水平。IKDC 主观膝关节评估表的平均评分为 91 分（范围 77-100）。平均 Lysholm 评分为 86 分（74-96）。与术前相比，所有这些评分均明显改善。MRI 未见相关隧道扩大。所有患者的锚固装置均被评估为完整。
结论
采用上述方法进行 ACLR 可获得良好的临床和影像学结果。
