The evaluation of the distance between the popliteus tendon and the lateral collateral ligament footprint and the implant in Total knee Arthroplasty using a 3-dimensional template.

BMC Musculoskelet Disord 2020 May 22;21(1):322. Epub 2020 May 22.

Department of Functional Morphology, Nihon University School of Medicine, Tokyo, Japan.

Background: The popliteus tendon (PT) or lateral collateral ligament (LCL) stabilizes the postero-lateral aspects of the knees. When surgeons perform total knee arthroplasty (TKA), PT and LCL iatrogenic injuries are a risk because the femoral attachments are relatively close to the femoral bone resection area. The purpose of this study was to evaluate the distance between the PT or LCL footprint and the TKA implant using a 3D template system and to evaluate any significant differences according to the implant model.

Klinik und Poliklinik für Unfallchirurgie, Klinikum rechts der Isar, Technische Universität München, Ismaninger Str. 22, 81675, München, Deutschland.

Shaft fractures of the tibia and fibula mainly affect younger patients and are therefore of great socioeconomic importance. Due to the high proportion of high-energy direct trauma mechanisms and the thin soft tissue covering layer of the ventromedian tibia, open factures occur in up to 39%. A structured diagnostic and therapeutic approach is essential for successful treatment. Read More

Medial Patellofemoral Ligament Reconstruction in Skeletally Immature Patients.

JBJS Essent Surg Tech 2020 Jan-Mar;10(1). Epub 2020 Feb 3.

Division of Pediatric Orthopaedic Surgery, Hospital for Special Surgery, New York, NY.

Patellofemoral instability is a common problem affecting children and adolescents, with recurrent instability often requiring surgical intervention. Medial patellofemoral ligament (MPFL) reconstruction has become a mainstay for the treatment of patellofemoral instability because of the biomechanical importance of the MPFL against lateral dislocation as well as the high frequency of MPFL injury following traumatic patellar dislocation. The concern in managing skeletally immature patients is the potential for injury to the distal femoral physis. Read More

Optimal configuration for stability and magnetic resonance imaging quality in temporary external fixation of tibial plateau fractures.

Orthop Traumatol Surg Res 2020 Mar 31. Epub 2020 Mar 31.

Department of Orthopaedic Surgery, Louisiana State University Health Science Center, Shreveport, LA, United States. Electronic address:

Introduction: Temporary external fixation has been widely utilized in the stabilization of plateau fractures while waiting for an optimization of the soft tissue conditions before subsequent permanent internal fixation. Simultaneously, MRI is beneficial in the assessment of concomitant damage to ligaments and menisci so that these injuries could be promptly identified, and surgical planning executed at the time of definitive fixation of the bony injury. Increasing numbers of side-bars and pins have been previously suggested to increase frame rigidity, but at the same time, several studies have indicated the presence of MRI artifacts which may obscure key anatomical structures, even when MRI-compatible fixation devices are used.

Department of Orthopedic Surgery (D.T.L., M.T.M) and Division of Trauma Surgery (K.A.E.), NYU Langone School of Medicine (L.J.G.), NYU Langone Orthopedic Hospital, New York, NY.

Tibial plateau fracture is an injury commonly seen by those who treat trauma around the knee and/or sports-related injuries. In this video article, we present our protocol for surgical treatment of a tibial plateau fracture, which includes definitive fixation with use of a plate-and-screw construct, addressing of all associated soft-tissue injuries at the time of the surgical procedure, filling of any residual voids with bone cement, and early rehabilitation with weight-bearing beginning at 10 to 12 weeks postoperatively. The major steps of the procedure are (1) preoperative planning with digitally templated plates and screws, (2) patient positioning and setup, (3) anterolateral approach toward the proximal aspect of the tibia, (4) submeniscal arthrotomy, (5) booking open of the proximal aspect of the tibia at the fracture site, (6) tagging of the meniscus, (7) fracture reduction and placement of the Kirschner wire, (8) confirmation of reduction with C-arm image intensification, (9) internal fixation with a plate-and-screw construct, and (10) closure.

Exploring new genetic variants within COL5A1 intron 4-exon 5 region and TGF-β family with risk of anterior cruciate ligament ruptures.

J Orthop Res 2020 Jan 10. Epub 2020 Jan 10.

Division of Exercise Science and Sports Medicine (ESSM), University of Cape Town, Cape Town, South Africa.

Variants within genes encoding structural and regulatory elements of ligaments have been associated with musculoskeletal soft tissue injury risk. The role of intron 4-exon 5 variants within the α1 chain of type V collagen (COL5A1) gene and genes of the transforming growth factor-β (TGF-β) family, TGFBR3 and TGFBI, was investigated on the risk of anterior cruciate ligament (ACL) ruptures. A case-control genetic association study was performed on 210 control (CON) and 249 participants with surgically diagnosed ruptures (ACL), of which 147 reported a noncontact mechanism of injury (NON).

Larger free flap size is associated with increased complications in lower extremity trauma reconstruction.

Microsurgery 2020 May 8;40(4):473-478. Epub 2020 Jan 8.

Hansjörg Wyss Department of Plastic Surgery, NYU Langone Health, New York, New York.

Background: Free flap reconstruction after lower extremity trauma remains challenging with various factors affecting overall success. Increasing defect and flap size have been demonstrated to be a surrogate for overall injury severity and correlated with complications. In addition, larger free flaps that encompass more tissue theoretically possess high metabolic demand, and may be more susceptible to ischemic insult. Read More

Primary Anterior Cruciate Ligament Repair With Hyaluronic Scaffold and Autogenous Bone Marrow Aspirate Augmentation in Adolescents With Open Physes.

Arthrosc Tech 2019 Dec 20;8(12):e1561-e1568. Epub 2019 Dec 20.

Orthopaedic Arthroscopic Surgery International (OASI) Bioresearch Foundation, Milan, Italy.

It is well known that the anterior cruciate ligament (ACL) is the main stabilizer to the anterior tibial translation in the knee. The current gold standard of treatment for such lesions is ACL reconstruction. However, there are notable disadvantages to ACL reconstruction that include loss of proprioception, donor site morbidity, incomplete return to high-demand sports, and the inability to restore normal kinematics of the knee joint.
