The Blumensaat ’s line morphology influences to the femoral tunnel position in anatomical ACL reconstruction

ConclusionFemoral ACL tunnel placement was significantly influenced by the morphological variations of the Blumensaat ’s line. As detecting morphological variation in arthroscopic surgery is difficult, surgeons should confirm such variations pre-operatively using radiograph or CT so as to avoid making extremely shallow and low tunnels in hill type knees.Level of evidenceCase-controlled study, III.

AbstractPurposeBone tunnel widening following anterior cruciate ligament reconstruction (ACLR) is well documented, although the aetiology and clinical significance of this phenomenon remain unclear. At mid-term follow-up, a greater prevalence of tunnel enlargement has been reported with the use of hamstring (HS) grafts. However, there are paucity of data on what happens in the longer term. The aim of this study was to assess the change in femoral and tibial tunnel dimensions 15  years after four-strand HS ACLR.MethodsThis is a retrospective review of 15 patients who underwent arthroscopic ACLR using HS autograft tendo...

ConclusionBimeniscal replacement by an allograft and/or substitute provides good short-term functional and anatomical outcomes. Nevertheless, this procedure is warranted only in highly selected patients.Level of evidenceIV, retrospective study.

Fu, Volker MusahlAbstractSmall intercondylar notch size is associated with increased risk of anterior cruciate ligament (ACL) injuries and increased difficulty of ACL reconstruction. When encountering a small notch during surgery, some surgeons may resort to a notchplasty, which has been shown to have associated morbidity. The ability to predict notch size on preoperative imaging could allow the orthopaedic surgeon to anticipate surgical difficulty su...

ConclusionsAnatomic ACL reconstruction could restore not only the normal anterior knee laxity, but also the normal tibiofemoral relationship even under an anterior tibial load.

J Knee Surg DOI: 10.1055/s-0039-1695040Patellar bone–tendon–bone (pBTB) autografts are often considered the “gold standard” for complete anterior cruciate ligament (ACL) reconstruction and are also associated with significant complications and early-onset knee osteoarthritis (OA). A novel quadriceps tendon allograft with synthetic augmentation, or “internal brace” (QTIB), has been reported to have potential advantages for ACL reconstruction based on animal model data. In this preclinical canine comparison study, we hypothesized that QTIB allograft compared with pBTB autograft would provi...

This study aimed to compare patient demographics, associated lesions (concurrent meniscal and chondral injuries), and clinical outcomes between revision and re-revision anterior cruciate ligament reconstructions.MethodsPatients who underwent revision or re-revision anterior cruciate ligament reconstruction between 2008 and 2016 with a minimum 2-year follow-up were retrospectively evaluated. Detailed patient demographic data, radiographic preoperative tunnel diameters, posterior tibia slope, and concurrent meniscal and chondral lesion were reviewed. Clinical scores and laxity tests ’ results were compared between the ...

To date, there is no consensus regarding which type of cortical suspension device is biomechanically superior during anterior cruciate ligament reconstruction. Retensioning or knotting has been reported to improve the biomechanical profile of adjustable-length devices, although fixed-length devices demonstrated overall superior biomechanical properties. Intraoperative or postoperative loop slippage and graft displacement should be investigated in future clinical and radiographic studies including serial magnetic resonance imaging.

ConclusionGood mid-term results were obtained for combined revision ACL reconstruction and lateral extra-articular procedures. Despite the fact that in clinical practice LET are a common indication associated with revision ACL, there are no high-level studies supporting this technique.Level of evidenceIV.

ConclusionACL reconstruction in patients older than 50  years is a safe procedure with good results that are comparable to those of younger patients previously reported. Age itself is not a contraindication to ACL surgery because physiological age, clinical symptoms and functional requests are more important than chronological age in decision process. Since cohort size in the present study is not large enough, and taking into account the high occurrence of concomitant meniscal and chondral lesions, more high-quality studies are necessary to draw definitive conclusions about development of osteoarthritis of the knee af...
