“…Nevertheless, it was thought that the size of the graft should not be larger than the footprint of ACL to avoid impingement. In a study, the footprint of the ACL on the femur condyle and tibial plateau was 13.8×10.6 mm and 13.4×10.2 mm, respectively 17. The method of this study harvested enough content of graft, not exceeded the expected dimensions.…”

Introduction:The quadriceps tendon (QT) is a common autologous graft for anterior cruciate ligament reconstruction. However, the best way to harvest it is still undefined. This study aims to determine the QT's anatomical structures as a graft for anterior cruciate ligament reconstruction and the ideal harvest site.Methods: Thirty fresh frozen knees from 15 cadavers were dissected, and the QT was analyzed. The length, depth, and width of the QT were measured in a standardized manner for each cadaver.Results: The QT superficial morphology showed 2 distinct peaks, with the maximum length correlating with the real lateral peak. The full length of the tendon was located at 64.3% 5.4% of the width from the medial border of the insertion. The maximum length of the QT was 79.4 4.5 mm. The mean width at its insertion onto the patella was 36.0 4.3 mm. The thickness at its maximum length on patella insertion was 7.2 0.4 mm. The mean diameter of the QT graft was 8.5 0.5 mm, with a mean cross-sectional area of 64.7 4.1 mm 2 . Conclusion:QT graft harvest should begin by locating the apex (maximum length) of the tendon (64.3% of the distance from the patella's medial edge). The surgeon should then harvest a 10 mm wide graft medially to the maximum length, harvesting 70 mm long and fullthickness tendon.

“…From the left to the right; Full-thickness QT with bone, Full-thickness QT without bone, Partialthickness QT without bone, BTB, double rectus femoris, quadruple semi-tendinosis Switzerland) to ensure symmetric size of the tendon graft and a minimum length of 80 mm. All QT grafts had 25 mm of exposed tendon between the two clamps in order to try to simulate a native ACL length [1,19,32]. For bone plug harvesting, a 10 mm width and a 25 mm length were measured, and a sagittal saw (Smith & Nephew Inc., Andover, Massachusetts) was used to harvest the bone plug.…”

Purpose Despite increasing interest in utilizing quadriceps tendon (QT) grafts in anterior cruciate ligament reconstruction (ACLR), data on the optimal quadriceps graft thickness are limited. The purpose of this study was to characterize the mechanical properties for the quadriceps tendon, comparing full-thickness (FT) QT grafts with and without bone to a partialthickness (PT) QT graft, and comparing the three QT grafts to four-stranded semitendinosus (4-SST) and bone-patellar tendon-bone (BTB) grafts and one experimental graft, the two-stranded rectus femoris (RF). Methods Forty-eight (n = 48) young cadaveric grafts (mean age 32 ± 6 years) were utilized for testing with N = 8 specimens in each of the following groups; (1) FT QT with bone, (2) FT QT without bone, (3) PT QT without bone, (4) BTB, (5) RF, and (6) 4-SST. Each specimen was harvested and rigidly fixed in custom clamps to a dynamic tensile testing machine for biomechanical evaluation. Graft ultimate load and stiffness were recorded. Independent groups one-factor ANOVAs and Tukey's pairwise comparisons were performed for statistical analyses. Results FT QT with bone and 4-SST grafts demonstrated similar ultimate loads to BTB grafts (both n.s), whereas PT QT demonstrate statistically significantly lower ultimate loads to BTB grafts (n.s) and 4-SST grafts (n.s). Furthermore, no statistically significant differences were observed between the ultimate loads of FT QT vs. PT QT grafts without bone (n.s) or between FT QT with vs. without bone (n.s). FT QT grafts with bone did not demonstrate statistically significantly greater ultimate loads than PT QT grafts without bone (n.s). The RF graft demonstrated statistically significantly lower ultimate loads to BTB grafts (p < 0.005) and 4-SST grafts (p < 0.014). Conclusions Full thickness QT grafts with bone had similar material properties to BTB and a 4-SST grafts, while Partial thickness QT graft without bone had significantly lower material properties than BTB and 4-SST, in a biomechanical setting.

“…По-перше, покращились наші знання про анатомію ПХЗ та роль різних її структурних елементів. Так з'явилась концепція ПХЗ у вигляді стрічки [8,9], була уточнена кількість та роль її пучків [10,11,12] та роль ПХЗ взагалі [13,14]. Покращилось розуміння значення ПХЗ для різних видів спорту, тому при лікуванні спортсменів високого рівня з підвищеними вимогами до стабільності колінного суглоба вже недостатньо знати про "часткове" ушкодження ПХЗ.…”

Summary. Standard MRI protocols of the knee joint in case of suspected anterior cruciate ligament (ACL) injury involve tomography in three mutually perpendicular planes – coronal, sagittal, and axial. Modern methods of treatment (especially refixation of the ACL and reconstruction of separate ACL bundles) and rehabilitation require more accurate diagnosis not only of the fact of injury, but also its clear location, degree and term. It is especially difficult to assess the nature and extent of ACL damage in the acute period and in cases of partial injury. Therefore, we propose to introduce into the standard of ACL MRI examination the additional use of oblique sagittal and oblique coronal sequences (images) oriented at an angle of ACL fibers with reduced to 0-2 mm interslice interval to improve the diagnosis of ACL injury. To reduce the duration of the study, it is possible to limit yourself to a small number of slices (images) in additional projections only in the area of the ACL.
