“…26 The mean width of the ACL calculated in the current study was 8.2 mm, ranging from 5.1-13.7 mm. This measurement differs slightly from the range of 7-12 mm as determined by Bicer et al, 7 Zantop et al 5 and Odensten and Gillquist. 25 Previous authors found the ACL to have a mean width of 10 mm 25 and 11 mm.…”

Background: Ligament grafts used in anterior cruciate ligament (ACL) reconstruction need to be the correct length for proper functioning. If the graft length is incorrect, the patient could risk knee instability, loss of range of motion, or failure of graft fixation. Easier and time-efficient reconstruction will be facilitated if the length of the ACL is predicted in advance.Apart from examining the morphological properties of the ACL, this study aimed to determine whether the epicondylar width of an individual can be used to predict ACL length and thereby assist in restoring the normal anatomy of the ACL.

“…In cross-section, the smallest part of the ligament is at the mid-substance, measuring between 36 and 48.9 mm 2 (Bicer et al, 2010), and the insertion sites are approximately 3.5 times greater in area (Harner et al, 1999). Structurally, the ligament is obliquely orientated within the knee and divided into collections of fascicles termed bundles (Arnoczky, 1983).…”

“…The tibial insertion of the ACL is considered the broadest part of the ligament and is described as either oval or triangular in shape (Bicer et al, 2010;Harner et al, 1999). Located in the anterior intercondylar fossa of the tibia and antero-lateral to the medial tibial spine, the area covered by the ACL is 7 -16 mm medial to lateral and 9 -19.5 mm anterior to posterior .…”

“…Described as a circle segment or oval shape, the size of the ACL at insertion ranges between 12.9 -17.2 mm proximal to distal and 6.8 -9.9 mm anterior to posterior (Piefer, Pflugner, Hwang, & Lubowitz, 2012), accounting for 45 -75 % of the lateral femoral notch (Dienst et al, 2002). Within the femoral footprint, the AM bundle is positioned proximal and anterior relative to the PL bundle, which is posterior and inferior [ Figure 2-3] (Bicer et al, 2010). …”

Graft tensioning in anterior cruciate ligament reconstruction

BackgroundAnterior cruciate ligament reconstruction (ACLR) is an effective procedure for restoring stability and function. Being a technically demanding procedure, patient outcomes are highly dependent on numerous surgical factors, which are critical for success. The application of tension to the graft prior to tibial fixation is one such factor and is considered essential for the restoration of joint stability, normal knee biomechanics, graft revascularisation and patient function. In applying tension, a key factor is the amount of force applied to the graft. However, the method of applying the tension, position of the knee during tensioning, properties of the graft material, tunnel placement and graft fixation device can all influence the effect that graft tension has on outcomes. Despite the reported importance of graft tension there has been limited empirical evidence defining the best tensioning practice for restoring patient outcome post ACLR. AimsThe goal of this program of research was to explore the effect that different aspects of graft tensioning has on patient function post ACLR. To address the aims of the thesis, three studies were conducted. The first study was a systematic review aimed at examining if a particular amount of tension results in better functional outcomes post ACLR. The second study aimed to compare the effect of two methods of applying graft tension on patient function post ACLR. The study used a prospective randomised controlled trial to compare manual tensioning with the use of a tensioning device. The third study aimed to define current graft tensioning practices and explore the factors that influence surgical decision making. A national survey of Australian orthopaedic surgeons was conducted to achieve the aims of the study. ResultsThe systematic review (study one) revealed that a medium graft tension of 79N to 90N produced the least side-to-side difference (STSD) in anterior posterior (AP) tibial translation as measured by a KT-1000 when compared to tensions <79 or >90N. However, the heterogeneous use of functional outcomes inhibited the ability to draw conclusions on other patient specific functional outcomes.Furthermore, the review highlighted the lack of high quality studies, which also failed to discuss other aspects of graft tension such as the method of applying tension.iii Building on the findings of study one, the second study undertook a RCT to compare the functional outcomes of applying 80N of force with a tensioning device (TD) (n=10) to a manual tensioning method (MT) (n=13) using an estimated force described as a sustained maximum one handed pull.Patients were assessed at pre-surgery and two weeks, three months, six months and 12 months post Based on the findings of study one, tensioning between 79N and 90N appeared to improve the restoration of joint stability, when compared to higher and lower tensions. However, no effect on patient function within 24 months post surgery was apparent. Furthermore, study two observed that tension did not appear to have an...
