BACKGROUND: Surgical reconstruction of ligaments and tendons is frequently required in clinical practice. The commonly used autografts, allografts, or synthetic transplants present limitations in terms of availability, biocompatibility, cost, and mechanical properties that tissue bioengineering aims to overcome. It classically combines an exogenous extracellular matrix with cells, but this approach remains complex and expensive. Using a rat model, we tested a new bioengineering strategy for the in vivo and de novo generation of autologous grafts without the addition of extracellular matrix or cells, and analyzed their biomechanical and structural properties...

Patients who suffer from the recurrent patellar dislocation mainly show the recurrent dislocation of patellar, giving way, most patients have the history of trauma or dysplasia of keen joint. Traditional therapies of recurrent patellar dislocation include medical retinaculum placation, lateral retinaculum release, tibial tubercle osteotomy, femoral trochleoplasty etc. In recent years, with the development of anatomical and biomechanical researches on medial patellofemoral ligament(MPFL), more and more experts focus on the role of MPFL played in preventing the patellar dislocation...

BACKGROUND: With the improvement of the surgical technique of Laparoscopic pancreaticoduodenectomy (LPD), indications will be extended to patients with vascular invasion. With LPD, vascular grafts for reconstruction are more frequently needed because adequate mobilization is not always done and vascular grafts can safely facilitate reconstruction. We describe our experience of reconstruction with the falciform ligament. METHODS: Venous reconstruction is performed after removal of the specimen...

The crossing internal suture augmentation technique is an all-inside technique of anterior cruciate ligament reconstruction with augmentation of the hamstring tendon autograft with a braided ultrahigh-molecular-weight polyester-polyethylene suture tape resting on the adjustable cortical buttons on both the femoral and tibial sides. The internal suture augmentation acts as a backbone supporting and protecting the graft until the process of healing and ligamentization of the graft is completed. The ends of the suture tape are tied on the tibial button and additionally fixed to the tibia with a knotless anchor as a backup fixation with the knee in full extension...

Bone defects caused by femoral and tibial tunnel enlargement can pose a significant technical challenge when planning to perform revision anterior cruciate ligament reconstruction. A number of options have been described for managing osseous deficiencies, including the use of large autograft or allograft bone dowels to provide sufficient tunnel fill and subsequent structural support for revision surgery. These techniques can be time-consuming and technically demanding to ensure proper tunnel fill and press-fit stability of the bone graft...

Posterolateral corner injuries are a severe and often unrecognized pathology. Injuries to these structures are difficult to identify using magnetic resonance images. Physical examination tests including the dial test, frog-leg test, and varus stress test can be difficult to perform. In addition it is difficult to correctly evaluate the results in a multiligament injury setting. The correct diagnosis of this pathology is essential to determine the proper treatment and improve outcomes. Furthermore, failure to recognize this pathology is associated with a high risk of failure following isolated anterior cruciate ligament reconstructions...

Brett Fritsch, Francisco Figueroa, Bertrand Semay
Hamstring autografts are frequently used for anterior cruciate ligament reconstruction. The inherent variability in graft diameter has been stated as a disadvantage in its use because the presence of smaller graft diameters has been correlated with increased risk of re-rupture. Several techniques have been described to address this concern. Modifications of the basic Graftlink technique allows for increased control over final graft diameter using a standard harvest of the semitendinosus tendon with or without the gracilis tendon, and results in a graft of adequate length and diameter in all patients with rigid cortical fixation on the femur and tibia...

Medial patellofemoral ligament (MPFL) injuries are common in children and young adults. In patients with recurrent patellar dislocations with normal lower-extremity alignment, anatomic reconstruction of the MPFL has been shown to restore patellar stability. We describe a technique that creates an anatomic reconstruction using a dual docking technique into the patella. Our technique is simple and efficacious for reconstructing the MPFL without implant fixation in the patella, allowing a maximal bone-tendon interface for healing...

Anterior cruciate ligament reconstruction is one of the most commonly performed procedures in orthopaedics, with more than 125,000 performed in the United States per year. There are several reconstruction graft choices that can be used to reconstruct the native anterior cruciate ligament, with autograft hamstring tendons being one of the most commonly used. Preparation of a hamstring autograft varies depending on patient characteristics and physician preference. The purpose of this Technical Note is to describe in detail different variants of hamstring graft preparation techniques that are commonly used in practice...

INTRODUCTION: Patients with anterior cruciate ligament (ACL) tears have persistent quadriceps strength deficits that are thought to be due to altered neurophysiological function. Our goal was to determine the changes in muscle fiber contractility independent of the ability of motor neurons to activate fibers. METHODS: We obtained quadriceps biopsies of patients undergoing ACL reconstruction, and additional biopsies one, two, and six months after surgery. Muscles fiber contractility was assessed in vitro, along with whole muscle strength testing...

BACKGROUND: Paediatric PCL injuries are rare but constitute a significant management challenge. We describe a novel approach to the surgical management of an 11-year-old boy who presented with persisting symptomatic instability following 18months of failed conservative therapy. METHODS: PCL reconstruction was performed using a physeal sparing, all-inside technique under fluoroscopic control. This avoids the potential for iatrogenic growth injury. A parentally donated hamstrings allograft was used to ensure adequate graft size, and reinforced using a non-elastic two millimetre braided suture...
