Santhanam Suresh, Gildasio S De Oliveira
We evaluated blood bupivacaine concentrations in children having a single-shot sciatic and continuous femoral blocks after anterior cruciate ligament repair. Dried blood spot samples were analyzed for bupivacaine levels at 0, 5, 15, 30, 60, and 120 minutes and 4, 24, and 48 hours. The highest 99% upper confidence interval limit was 135 ng/mL at the 4-hour evaluation point. The 99% upper confidence interval was below potentially toxic levels (1500 ng/mL) across all sampling times. The risk of local anesthetic toxicity in pediatric patients receiving single-shot sciatic and continuous femoral nerve blocks is very low...

Traumatic lunate fractures are very rare and those treatments require an understanding of anatomical features. We present a case of an ulnolunate ligament avulsion fracture of the lunate that was successfully repaired by surgical fixation with open reduction and internal fixation. We believe that restoration of ulnolunate ligament function is important to prevent further deterioration of wrist function after this injury.

BACKGROUND: Revision anterior cruciate ligament reconstruction (ACLR) is becoming increasingly common as the number of primary ACLR cases continues to rise. Despite this, there are limited data on the outcomes of revision ACLR and even less information specifically addressing the differences in 1-stage revision reconstruction versus those performed in a 2-stage fashion after primary reconstruction. PURPOSE: To compare the outcomes, patient satisfaction, and failure rates of 1-stage versus 2-stage revision ACLR...

Soft supporting tissues in the human body, such as cartilages and ligaments, are tough materials and firmly fixed to bones. These soft tissues, once injured, cannot regenerate spontaneously invivo. Developing tough and biocompatible hydrogels as artificial soft supporting tissues would substantially improve outcomes after soft tissue injury. Collagen is the main rigid component in soft connective tissues which is organized in various hierarchical arrays. We have successfully developed a novel class of collagen fibril-based tough hydrogels based on the double network (DN) concept using swim bladder collagen (SBC) extracted from Bester sturgeon fish...

INTRODUCTION: The operative treatment of unstable pelvic injuries in paediatrics is not frequently indicated. The detailed modes of pelvic ring failure, surgical techniques, fixation choices, and peri-operative difficulties are not well reported. METHODS: From September 2010 to March 2016, 62 paediatric patients were admitted to an academic level I trauma center with the diagnosis of pelvic ring injury. Of them, 29 (17 males and 12 females) had operative fixation of unstable pelvic injuries...

Meniscal root tears occur in isolation or concurrently with ligamentous knee injury and cause significantly altered knee mechanics with the loss of normal meniscus hoop stress. This loss of normal meniscus function can result in abnormal knee kinematics and, subsequently, more rapid degenerative changes of the knee articular surface. In the setting of anterior cruciate ligament tear, the posterolateral meniscus root is most commonly damaged. Several techniques exist for meniscus root repair; however, none have been shown to be clearly superior...

INTRODUCTION AND HYPOTHESIS: Several reports have described vaginal prolapse in Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome patients after creation of a neovagina. To our knowledge, no reports of primary vaginal prolapse of a blind pouch without previous intervention, or surgery for this condition, have been described. METHODS: In this case report, we describe a 19-year-old woman with MRKH and complete prolapse of her shortened vaginal pouch. Surgical correction utilizing permanent suture-based sacrospinous ligament fixation was performed...

Roger P van Riet
Simple elbow dislocations are usually treated conservatively. Radiographs are negative in simple dislocations. Results are generally good, although a small percentage of patients may develop chronic instability. Ligamentous repair can be indicated in high demand patients or if the elbow remains unstable following a closed reduction. Chronic instability is classified per their direction. Surgery is often indicated in the chronically unstable elbow.

BACKGROUND: Early ACL reconstruction, before retuning to activity eliminates recurrent episodes of instability and thereby decreases chances of meniscal and cartilage injury. However, there are no clear and uniform guidelines regarding the timing of ACL reconstruction or clarity in the definition of early and delayed reconstruction to reduce the complications after reconstruction in the ACL injured knee. The purpose of this study was to compare the clinical outcome, stability, muscle power, and postural control after early and delayed anterior cruciate ligament (ACL) reconstruction...

BACKGROUND: Access to the plantar plate has been described using either a plantar approach or an extensive dorsal approach that required complete joint destabilization and often a metatarsal osteotomy. Clinical scenarios related to plantar plate tear vary and the pathologies in early stages are frequently limited to unilateral soft tissue structures; a less invasive operative approach may be possible. A novel approach requiring a release of only the lateral collateral ligament and the lateral half of the plantar plate is presented in this cadaver model; the extent of joint exposure possible is described...

BACKGROUND: Traumatic tears of the tibialis posterior (TP) tendon following an ankle sprain are rare. The purpose of this study was to report our case series of TP tendon tears following an ankle sprain. METHODS: Patients with persistent TP tendon pain after an ankle sprain were retrospectively identified over a 4-year period and reviewed. A comparison of magnetic resonance imaging (MRI) interpretations by a radiologist and surgeon was made. Patients failing conservative management underwent operative repair of the TP tendon tear and concomitant pathology...

BACKGROUND: The open modified Broström anatomic repair technique is widely accepted as the reference standard for lateral ankle stabilization. Despite recent increases in publications regarding arthroscopic repair of the anterior talofibular ligament (ATFL) for treatment of chronic ankle instability, research is lacking that compares the functional outcomes between arthroscopic repair and open repair procedures for chronic ankle instability. PURPOSE: To compare function and activity level after arthroscopic repair versus open repair of the ATFL in patients with lateral ankle instability...

BACKGROUND: The purpose was retrospectively to investigate functional and clinical outcomes after anterior talofibular ligament (ATFL) and calcaneofibular ligament (CFL) reconstruction using a single allograft. METHODS: Patients with severe chronic lateral instability of the ankle underwent surgery after conservative treatment failed. Ultrasounds of the ankle were performed, and if the AFTL and CFL were completely torn without enough soft tissue for repair, the ligaments were reconstructed using allograft tendon...

The Multicenter Orthopaedic Outcomes Network (MOON) is an NIH-funded prospective, longitudinal cohort of over 3500 patients who have undergone anterior cruciate ligament reconstruction (ACLR) by 14 sports medicine surgeons at 7 academic medical centers. Patient reported outcome questionnaires (PRO's) are completed at baseline and multiple timepoints after surgery, and a nested cohort of patients return for radiographs to assess the development of joint space changes. We review the risk factors for worse patient reported outcomes, the predictors of clinically significant symptoms of post-traumatic osteoarthritis (PTOA), and the factors associated with more radiographic joint space narrowing...

Anterior cruciate ligament (ACL) rupture is a common condition that can be devastating and life changing, particularly in young adults. A non-contact mechanism is typical. Second ACL ruptures through rupture of the contralateral ACL or rupture of a graft repair is also common. Risk of rupture is increased in females. ACL rupture is also common in dogs. Disease prevalence exceeds 5% in several dog breeds, ~100 fold higher than human beings. We provide insight into the genetic etiology of ACL rupture by genome-wide association study (GWAS) in a high-risk breed using 98 case and 139 control Labrador Retrievers...

Tibial spine avulsion fractures are uncommon knee injuries that predominantly occur in children and young adults. Restoration of anterior cruciate ligament length through surgical reduction and fixation of the fracture is necessary to ensure stability of the knee with suitable range of motion and minimal knee laxity. Arthroscopic repair of tibial spine avulsion fractures is a technically complex procedure, specifically when performing and maintaining the initial anatomic reduction. We describe in this technical note and accompanying video a unique 3-point fixation repair of tibial spine avulsion fractures using an arthroscopic assisted suture lever reduction technique...

Scapholunate ligament (SLL) injury is the most frequent injury of the intrinsic carpal ligaments. The dorsal part of the SLL is the most important part for the stability of the scapholunate joint, and tears of this part and at least one of its secondary capsular attachments cause scapholunate dissociation. The arthroscopic technique most frequently used for acute injuries is reduction and fixation with Kirschner wires, and techniques that involve a primary repair of the injured ligament are performed by open surgery with efficient results...

The radioulnar ligament of the triangular fibrocartilage complex (TFCC), especially the deep fibers inserted at the ulnar fovea, is the key component for the distal radioulnar joint (DRUJ) stability. Traumatic injuries to the TFCC foveal insertion would cause DRUJ instability. Traditionally, arthroscopic techniques of the TFCC repair are suturing the ulnar-sided disruption peripherally to the dorsal or ulnar capsule instead of suturing the TFCC to the fovea and thus fail to restore the DRUJ stability if the TFCC is detached from the fovea...
