“…Indeed, this review observed that the most consistent arthroscopic landmark for the tibial footprint was the anterior border of the posterior cruciate ligament, with the tibial footprint center 15 mm anterior to the border (Cuomo et al 2006; Edwards et al 2007; Heming et al 2007). However, it is worth noting that Hussein et al (Hwang et al 2012) performed a systematic review of subjective interpretations and failed to provide a definitive, quantitative synthesis through meta-analyses.…”

BackgroundTo determine if tibial tunnel reaming during anatomic single-bundle anterior cruciate ligament (ACL) reconstruction using hamstring autograft can result in anterolateral meniscal root injury, as diagnosed by magnetic resonance imaging (MRI).MethodsA case series of 104 primary anatomic single-bundle ACL reconstructions using hamstring autograft was retrospectively reviewed. Pre- and post-operative (>1 year) MRIs were radiologically evaluated for each patient, with a lateral meniscus extrusion > 3 mm at the level of the medial collateral ligament midportion on a coronal MRI, to establish anterolateral meniscal root injury.ResultsNo patients presented radiological findings of anterolateral meniscal root injury in this case series.ConclusionsExamining a single-bundle ACL reconstruction technique using hamstring autograft that considered tibial tunnel positioning in the center of the tibial footprint, this case series found no evidence of anterolateral meniscal root injury in patient MRIs, even more than 1-year post-operation.

“…First, the cartilage-based GPA provided a common geometric base across the specimens, effectively serving as a 3D geometric normalization procedure. In conventional morphometric studies, insertion site locations are expressed as percentages of the tibial plateau depth or width or similar representation and the normalization is therefore based on a single dimension [11], [15], [27], [28]. An underlying assumption for single-dimension-based normalization is that the involved morphometric measures adhere to isometric rather than allometric scaling [45].…”

“…A few observational studies have described the locations of the meniscal root attachments in relation to bony or soft tissue landmarks [31]–[33], but the location measures were not scaled or normalized by any tibial measure to elicit potential invariant or common morphological features. The shape variability of cruciate ligament insertions has been documented largely by qualitative descriptions [28], [29], [34], [35]. The ACL tibial insertion sites were found to be triangular or oval in most specimens in some studies [22], [36], and to be more variable than that of the femoral attachments in others [24], [28], [34].…”

The Morphometry of Soft Tissue Insertions on the Tibial Plateau: Data Acquisition and Statistical Shape Analysis

2014

This study characterized the soft tissue insertion morphometrics on the tibial plateau and their inter-relationships as well as variabilities. The outlines of the cruciate ligament and meniscal root insertions along with the medial and lateral cartilage on 20 cadaveric tibias (10 left and 10 right knees) were digitized and co-registered with corresponding CT-based 3D bone models. Generalized Procrustes Analysis was employed in conjunction with Principal Components Analysis to first create a geometric consensus based on tibial cartilage and then determine the means and variations of insertion morphometrics including shape, size, location, and inter-relationship measures. Step-wise regression analysis was conducted in search of parsimonious models relating the morphometric measures to the tibial plateau width and depth, and basic anthropometric and gender factors. The analyses resulted in statistical morphometric representations for Procrustes-superimposed cruciate ligament and meniscus insertions, and identified only a few moderate correlations (R 2: 0.37–0.49). The study provided evidence challenging the isometric scaling based on a single dimension frequently employed in related morphometric studies, and data for evaluating cruciate ligament reconstruction strategies in terms of re-creating the native anatomy and minimizing the risk of iatrogenic injury. It paved the way for future development of computer-aided personalized orthopaedic surgery applications improving the quality of care and patient safety, and biomechanical models with a better population or average representation.

“…Regardless of the surgical intervention method used, the key element in ACL surgery remains knee and ACL anatomy, which have been resolved thoroughly for the tibial and femoral sides [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. The ACL has two bundles, anteromedial and posterolateral, the names given from the tibial insertion site.…”

Purpose Anterior cruciate ligament (ACL) reconstruction has been under intensive discussion and debate, although the anatomy of this ligament was resolved thoroughly almost 200 years ago. The ACL consist of two bundles, anteromedial (AM) and posterolateral (PL). The conventional single-bundle method reconstructs the AM bundle only, while the modern double-bundle technique recreates both bundles for their anatomical sites. Methods An English language literature search was undertaken over the years 2000-2012 for ACL reconstruction, double-bundle versus single bundle technique. The search found 14 RCTs and two meta-analyses published to date. Results Two of the 14 studies (14 %) showed no difference between the two reconstruction methods while the remaining majority (12 trials, 86 %) concluded that the DB technique was better than the SB method. After the DB reconstruction, rotational stability of the knee was better in seven studies (50 %) and anteroposterior stability in six (43 %). No study spoke for the single-bundle technique. In addition, with the double-bundle technique knee scores were reported to be better in five (36 %) studies, and three trials (21 %) revealed less reoperations in the double-bundle group. Conclusions The double-bundle ACL reconstruction technique was reported to have better or at least the same results as the conventional single-bundle method-even at a fiveyear follow-up. However, the majority of these studies had a rather short follow-up, and thus, longer studies are needed to confirm the true long-term results of ACL surgery. Long follow-up periods are also needed to find out whether double-bundle ACL reconstruction can eventually prevent knee osteoarthritis.
