“…And these studies focused on the correlation between CSA and diameter of hamstring tendon on preoperative MRI and intraoperative hamstring graft size. [1,[6][7][8] For this reason, standard sections were evaluated for the comparisons. Wernecke et al, [6] Bickel et al, [7] and Erquicia et al [8] measured the ST diameter at the level of the largest region of the medial femoral condyle, and Beyzadeoglu et al [1] measured at two different levels -distal to the musculotendinous junction and at the level of the JL.…”

“…However, 7 mm was considered as the baseline threshold value in some MRI studies. [1,6,7] Measurements were performed under × 10 magnification by an observer blinded to the intraoperative measurements of the autograft diameter. A significant statistical correlation was found between the diameter of the 4-stranded ST autograft and ML diameter and the AP diameter at both levels.…”

“…Regarding the success of ACL reconstruction, the major factor for hamstring autograft is the graft size. [1,2] As it is widely accepted opinion that hamstring tendon autograft should be at least 7 mm in diameter for a successful treatment. [2,3] In recent studies, the authors have indicated that the diameter of tendon equal to or more than 8 mm decreases the risk of graft failure.…”

“…[1,[6][7][8][9][10] In all studies about this subject, both gracilis tendon (GT) and semitendinosus tendon (ST) were used for ACL reconstruction. [1,[6][7][8][9][10] Some authors prefer both ST and GT to obtain 4-stranded autograft, whereas some of them prefer only ST in singlebundle ACL reconstruction. [7,11] This present study was designed for primary ACL reconstruction technique with 4-stranded ST autograft.…”

Aims & Objectives:To assess the accuracy of preoperative measurement of Hamstring graft thickness using Magnetic Resonance Imaging (MRI) with intra-operative measurements. Materials: The present prospective type of clinical study was conducted. A total of 50 patients operated for Anterior Cruciate Ligament (ACL) reconstruction were selected for the study. Informed consent was obtained from all study participants. Patients who fulfilled the inclusion criteria were studied and evaluated. Results and Observations: It was observed that the maximum number of patients (56%) belonged to age group 21-30 years. The mean ± standard deviation of age was 31.04±6.58. It was observed that 72% of patients were males and 28% females, the mean ± standard deviation of anteroposterior (AP) and mediolateral (ML) diameter of semitendinosis on Magnetic Resonance Imaging at joint line was 6.34±0.88 and 6.57±0.71 respectively. The anteroposterior and mediolateral diameter of semitendinosis on Magnetic Resonance Imaging at physeal line was 6.71±0.61 and 6.99±0.39 respectively. It was observed that the measured values on Magnetic Resonance Imaging at joint level and physeal level correlated with the intraoperative values of semitendinosis graft and p value was significant. (p value<0.05). Conclusion: A significant statistical correlation was found between the diameter of the 4-stranded semitendinosis autograft and mediolateral diameter and the anteroposterior diameter at both levels.

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...

PurposeTo evaluate the utility of semitendinosus tendon (ST) and gracilis tendon (GT) cross‐sectional area (CSA) on magnetic resonance imaging (MRI) and anthropometric characteristics in preoperative estimation of graft diameter in patients undergoing anterior cruciate ligament reconstruction (ACLR) with four‐strand hamstring autografts.MethodsThree databases were searched on 29 August 2023. The authors adhered to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta‐Analyses) and R‐AMSTAR (Revised Assessment of Multiple Systematic Review) guidelines and the Cochrane Handbook for Systematic Reviews of Interventions. Data on demographics, anthropometric characteristics, imaging techniques, tendon CSA, correlation coefficients, sensitivities, specificities, regression models and cutoffs for predicting intraoperative graft diameters above 8 mm were recorded.ResultsForty‐six studies comprising 4140 patients were included. Twelve of 19 (63.2%) studies reporting on ST + GT CSA found a moderate to very high correlation with intraoperative graft diameter. Five of 10 (50%) and one of seven (14.3%) studies reporting on ST CSA and GT CSA, respectively, found a moderate to high correlation with intraoperative graft diameter. Cutoffs of ST + GT CSA for predicting graft diameters above 8 mm ranged from 15.8 to 31.2 mm2. Nine of 35 (25.7%) studies that reported on height found a moderate to very high correlation with graft diameter. Seven of 33 (21.2%) studies reporting on weight found a moderate correlation with graft diameter.ConclusionOf the MRI parameters assessed, ST + GT CSA was the most reliable predictor of graft diameter. However, cutoffs, sensitivities, and specificities for predicting diameters above 8 mm were highly variable. Anthropometric characteristics in general were less predictive of graft diameter than MRI parameters. This information can be used by clinicians to predict patients at risk for ACLR failure due to insufficient graft size.Level of EvidenceLevel IV.
