“…Causes of graft failure are multifactorial with the most important being trauma, technical error and failure of graft incorporation (12). It has not yet been determined which fixation method and what position of the drilling tunnels offers a lower rate of graft failure (12,13). Graft failure rate in our study was 12% and the result is comparable with previous papers, which reported graft failure of quadruple stranded STGR in 4% -15.3% (13,14).…”

Background: Anterior cruciate ligament reconstruction (ACL-R) technique affects graft positioning. However, how ACL graft positioning affects graft signal intensity (GSI) is yet unknown. The aim of our study was to find out if ACL-R technique affects GSI at mid-term follow-up. Methods: A total of 50 patients were included in the study. They underwent 3.0 T MRI of the knee 4-7 years after ACL-R. Patients were divided into two groups according to ACL-R technique (transtibial technique with RIGIDfix fixation [group 1] and anteromedial portal technique with Endobutton fixation [group 2]). GSI, graft failure, graft impingement and graft position were assessed. GSI characteristics were evaluated on proton density turbo spin echo fat saturation images. Graft was divided into two portionsintraarticular portion (IAP) and intraosseous portion (IOP). Intraosseous portion was further divided into two parts -femoral (fIOP) and tibial (tIOP). Results: Graft failure was identified in 12.0%. Only 9.8% showed low signal intensity of the entire graft course. Group 2 showed higher rates of increased graft signal intensity (IGSI) of the IAP and fIOP. Patients with IGSI of the IAP showed more horizontal position of the coronal tibial tunnel. Patients with IGSI of the fIOP showed more horizontal position of the coronal femoral tunnel. Patients with IGSI of the tIOP showed more horizontal position of the sagittal tibial tunnel. Conclusions: IGSI can be seen in the majority of patients after ACL-R at mid-term follow-up. Our study demonstrates that graft tunnel positioning and graft fixation device may influence GSI.

“…One systematic review cited a 6.8 times greater relative risk of failure at or below 8 mm in width and noted that in the patients younger than 20 years of age grafts larger than 8 mm decreased failure rates [7]. One retrospective study showed revision was non-existent in patients of all ages with graft size >8 mm and that 18.3% of patients less than 18 years old and with a graft width of less than 8 mm underwent revision.…”

“…[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. [2,4] However, the diameter of the hamstring graft can only be determined after folding the harvested autograft into 4-stranded. [5] This situation leads to interest in finding ways to predict graft diameter preoperatively.…”

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.
