The occurrence of ACL injury influenced by the variance in width between the tibial spine and the femoral intercondylar notch

ConclusionBoth tibial spine width/notch outlet length and tibial spine width/notch width index were significantly smaller in the ACL tear group when compared with the ACL intact group. The occurrence of ACL injury influenced by the variance in width between the tibial spine and the femoral intercondylar notch.Level of evidenceIII.

ConclusionOverall, the AE ACLR technique can achieve good postoperative functional outcomes while notably minimizing the incidence of primary issue of physeal disruption and potential associated leg-length discrepancies. AE ACLR should be considered in pediatric patients with at least 2  years of skeletal growth remaining based on radiographic bone age to minimize the impact of growth-related complications.Level of evidenceIV (Systematic Review of Level III and IV evidence).

Anterior cruciate ligament (ACL) reconstruction is a commonly performed procedure, with an increasing frequency leading to an increased number of revision procedures. Etiologies for graft rupture are varied and can include technical issues, repeat trauma, and graft choice. The preoperative evaluation before a revision ACL reconstruction should include a detailed history and physical exam, as well as radiographs, magnetic resonance imaging to evaluate graft integrity and for concomitant injuries, as well as computed tomography to measure for bone tunnel osteolysis. Surgical techniques for revision ACL reconstruction include...

ConclusionACL reconstruction provides satisfactory knee stability. The risk of subsequent osteoarthritis depends chiefly on the status of the menisci. Residual laxity is also associated with the development of osteoarthritis.Level of evidenceIV, retrospective cohort study.

This study sought to postoperatively compare femoral cortical button (FCB) placement in anterior cruciate ligament (ACL) reconstruction performed using an adjustable loop cortical femoral fixation button under direct arthroscopic visualization vs indirect methods. The authors conducted a retrospective review of postoperative knee radiographs from 76 patients who had undergone ACL reconstruction with an adjustable loop cortical femoral fixation button. Operative reports were reviewed to determine the technique used for graft placement. Two sports fellowship-trained surgeons reviewed the collected radiographs, and the positi...

ConclusionsACL reconstruction in the juvenile with living parental hamstring tendon allograft is a viable procedure associated with excellent clinical stability, patient-reported outcomes and return to sport over 2  years. Further ACL injury to the reconstructed and the contralateral knee remains a significant risk, with identical prevalence observed between the reconstructed and contralateral ACL between 12 and 24 months after surgery.Level of evidenceIII (Cohort Study).

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.

Publication date: Available online 26 September 2019Source: Arthroscopy TechniquesAuthor(s): Ravi Vaswani, Sean J. Meredith, Jayson Lian, Ryan Li, Michael Nickoli, Freddie H. 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.
