- Midterm Clinical Outcome of Combined Posterior Cruciate Ligament Reconstruction and Posterolateral Corner Surgery Using Second-Look Arthroscopic "Lateral Gutter Drive-Through" Test as an Adjunctive Evaluation. [Journal Article]
- OSOrthop Surg 2019; 11(3):422-430
- CONCLUSIONS: In the series of surgically treated patients with PCL and PLC injury: (i) patients had improved subjective and objective clinical outcome after combined PCL reconstruction and PLC surgery at a minimum of 24-months follow-up; and (ii) second arthroscopic LGDT sign testing had high sensitivity and specificity in detecting postoperative PLRI, and a positive LGDT sign was related with inferior subjective and objective results.
- Radiographic study of the development of the pelvis and hip and the femorotibial joints in domestic cats. [Journal Article]
- JFJ Feline Med Surg 2019 Jun 11; :1098612X19854809
- CONCLUSIONS: The complete closure of the growth plates of domestic cats occurs at approximately 18 months of age. Skeletal maturation at approximately 18 months of age is an important parameter to be considered in radiographic evaluation of certain skeletal changes, evolution of fractures and nutritional imbalance.
- Does Knee Flexion Influence the Relationship between the Femoral Tunnel and the Lateral Anatomic Structures During ACL Reconstruction? [Journal Article]
- COClin Orthop Relat Res 2019 May 30
- CONCLUSIONS: As knee flexion increased, the femoral tunnel's outlet tended to move more anteriorly and distally. Consequently, the safe distance to the lateral head of the gastrocnemius increased and the distances to the lateral epicondyle, lateral collateral ligament, and popliteus tendon decreased with increased knee flexion. To avoid possible damage to the lateral anatomic structures and obtain stable fixation in ACL reconstruction using the transportal technique, we recommend creating a femoral tunnel within 121° and 131° of knee flexion.
- The International Society of Arthroscopy, Knee Surgery and Orthopaedic Sports Medicine classification of knee meniscus tears: three-dimensional MRI and arthroscopy correlation. [Journal Article]
- EREur Radiol 2019 May 21
- CONCLUSIONS: The ISAKOS classification of meniscal tears on 3D MRI provides mostly moderate agreement, which was similar to the agreement at arthroscopy.• There is a fair to good inter-method correlation in most categories of ISAKOS meniscus tear classification. • The tear lengths are significantly larger on MRI than on arthroscopy. • The inter-reader correlation on 3D MRI is moderate to excellent, with the exception of lateral meniscus tear patterns.
- Types of posterolateral corner injury associated with both bundle and selective-bundle ACL tears. [Journal Article]
- ARActa Radiol 2019 May 01; :284185119842833
- CONCLUSIONS: Superior PMF injury is more common in both-bundle tears than selective-bundle tears. There is no statistically significant difference in the prevalence of PLC injury between both-bundle tears and selective-bundle tears.

The first edition of the Terminologia Anatomica was published in 1998 by the Federative Committee on Anatomical Terminology, whereas the second edition was issued in 2011 by the Federative International Programme on Anatomical Terminologies. Since then many attempts have been made to revise and extend the official terminology as several inconsistencies have been noted. Moreover, numerous crucial terms were either omitted or deliberately excluded from the official terminology, like sulcus popliteus and diaphragma urogenitale, respectively. Furthermore, several synonyms are to be discarded. Notwithstanding the criticism, the use of the current version of terminology is strongly recommended. Although the Terminologia Anatomica is open to future expansion and revision, every change should be made after a thorough discussion of the historical context and scientific legitimacy of a given term. The anatomical nomenclature must be as simple as possible but also precise and coherent. It is generally accepted that hasty innovation ought not to be endorsed. Therefore, there is a need to take a closer look at these new proposals as they have been presented in numerous dispersed papers. This article provides an overview of these issues and concentrates on selected revisions and extensions that are didactically and clinically useful, thereby summarising the salient aspects of these new and compelling proposals.

The original description of the LaPrade technique for anatomic posterolateral corner reconstruction addresses the 3 main stabilizing structures: the fibular collateral ligament, the popliteus, and the popliteofibular ligament. The use of two separate grafts (originally described with a tendo-Achilles allograft) may restrict the utility of the technique when sources of allograft may be limited and autografts must be used, particularly in the context of multiligament reconstruction. We present a modification of the technique, in which an adjustable cortical button is used for tibial fixation, which allows for the use of a single graft while maintaining the ability to independently tension the popliteus, popliteofibular ligament, and fibular collateral ligament limbs of the graft.

The flexor hallucis longus (FHL) muscle is one of the four muscles that compose the deep posterior compartment of the lower limb. The other three deep muscles are the flexor digitorum longus (FDL), tibialis posterior, and popliteus muscles. The flexor hallucis longus originates at the posterior surface of the fibula, inserting at the plantar aspect at the base of the distal phalanx of the great toe. The flexor hallucis longus' primary function is flexion of the great toe, also serving to plantarflex and invert the foot. The antagonistic muscle is the extensor hallucis longus (EHL).

Posterolateral corner (PLC) structures of the knee joint comprise complex anatomical soft tissues that support static and dynamic functional movements of the knee. Most previous studies analyzed posterolateral stability in vitro under static loading conditions. This study aimed to evaluate the contributions of the lateral (fibular) collateral ligament (LCL), popliteofibular ligament (PFL), and popliteus tendon (PT) to cruciate ligament forces under simulated dynamic loading conditions by using selective individual resection. We combined medical imaging and motion capture of healthy subjects (four males and one female) to develop subject-specific knee models that simulated the 12 degrees of freedom of tibiofemoral and patellofemoral joint behaviors. These computational models were validated by comparing electromyographic (EMG) data with muscle activation data and were based on previous experimental studies. A rigid multi-body dynamics simulation using a lower extremity musculoskeletal model was performed to incorporate intact and selective resection of ligaments, based on a novel force-dependent kinematics method, during gait (walking) and squatting. Deficiency of the PLC structures resulted in increased loading on the posterior cruciate ligament and anterior cruciate ligament. Among PLC structures, the PT is the most influential on cruciate ligament forces under dynamic loading conditions.
