摘要

目的比较4股HS ACLR直径≥8mm （HS-ACLR- 4s≥8mm）患者与4股HS ACLR直径≥8mm （HS-ACLR- 4s≥8mm）患者制备5股、6股、7股或8股前交叉韧带重建（ACLR）移植物的腘绳肌腱足够长的比例。方法纳入2008年至2018年期间因单束ACLR接受内侧HS采集的患者。如果ACLR移植物是双半腱肌和双股薄肌，并且它们骨骼成熟，则纳入患者。主要结果是HS的长度。比较HS-ACLR- 4s与HS-ACLR- 4s≥8mm和HS-ACLR- 4s≥8mm的成功制备5股或更多肌腱（HS-ACLR≥5S）的可能性。报告了任何与HS-ACLR≥5S制备可行性显著相关的人体测量因素。结果共纳入296例患者，其中男性223例，女性73例。HS-ACLR-4S≥8 mm 100例，HS-ACLR-4S≥8 mm 196例。与HS- aclr - 4s≥8 mm组相比，HS- aclr - 4s≥8 mm组的HS长度更短(P <；措施)。两组成功制备5股移植物的几率无显著差异(分别为97%和98%；P = .327)。然而，在HS-ACLR-4S = 8-mm的患者中，使用6股或7股肌腱制备ACLR移植物的机会较低(P = 0.031和P <；措施,分别)。此外，身高是成功制备超过5股肌腱的HS-ACLR的可能性的唯一独立预测因子。结论不论HS-ACLR-4S移植体直径小于8mm还是大于8mm，制备5链ACLR移植体几乎都是可行的。较矮的身高与成功制备5股肌腱HS-ACLR的机会较低相关。然而，与HS- aclr - 4s≥8mm的患者相比，HS- aclr - 4s≥8mm的患者成功制备6股和7股HS- aclr移植物的可能性较低。临床相关性了解与ACL - HS肌腱自体移植物制备相关的因素可以使外科医生确保移植物具有足够的长度和直径。

Four-Strand Hamstring Autografts Less Than 8-mm Wide Provide Less Capability for Conversion to a 6- or 7-Strand Graft Than Larger-Diameter Hamstring Autografts

Purpose

To report the proportion of patients who have long-enough hamstring (HS) tendons to prepare an anterior cruciate ligament reconstruction (ACLR) graft of 5 strands, 6 strands, 7 strands, or 8 strands in patients with a small 4-strand HS ACLR graft diameter <8 mm (HS-ACLR-4S <8 mm) compared with patients who had a 4-strand HS ACLR graft diameter ≥8 mm (HS-ACLR-4S ≥8 mm).

Methods

Patients who underwent medial HS harvest for single-bundle ACLR between 2008 and 2018 were included. Patients were included if the ACLR graft was a doubled semitendinosus and doubled gracilis autograft and they were skeletally mature. The primary outcome was the length of the HS. The likelihood of successful preparing an HS ACLR with 5 strands of tendons or more (HS-ACLR ≥5S) was compared between HS-ACLR-4S <8 mm and HS-ACLR-4S ≥8 mm. Any anthropometric factors significantly associated with the feasibility of preparing a HS-ACLR≥5S were reported.

Results

A total of 296 patients, including 223 men and 73 women, were included. One hundred patients had HS-ACLR-4S <8 mm, whereas 196 patients had HS-ACLR-4S ≥8 mm. The length of the HS was shorter in the HS-ACLR-4S <8-mm group compared with the HS-ACLR-4S ≥8-mm group (P < .001). There was no significant difference between the 2 groups in the chance of successfully preparing a 5-strand graft (97% and 98%, respectively; P = .327). However, there was a lower chance of preparing an ACLR graft using 6 or 7 strands of tendons in patients with HS-ACLR-4S <8-mm (P = .031 and P < .001, respectively). In addition, body height was the sole independent predictor of the likelihood of successfully preparing a HS-ACLR of more than 5 strands of tendon.

Conclusions

Preparation of a 5-strand ACLR graft is almost always possible, regardless of whether the HS-ACLR-4S graft diameter was less than 8 mm or 8 mm or greater. Shorter body height was associated with a lower chance of successfully preparing an HS-ACLR with 5 strands of tendons. However, the likelihood of successfully preparing a 6-strand and a 7-strand HS-ACLR graft were lower in the group of patients with an HS-ACLR-4S <8 mm compared with HS-ACLR-4S ≥8 mm.
