Background: Knee osteoarthritis is a common disease with increasing incidence and prevalence in western countries. It can cause severe pain and functional limitations, thereby representing a threat for patients' quality of life and a burden for national health systems. Intra-articular injections with hyaluronic acid (HA) and platelet-rich plasma (...

Purpose: Gait analysis was used to evaluate knee kinematics in patients who underwent successful primary total knee arthroplasty (TKA) using two modern bi-cruciate substituting designs. The knee joint was balanced intraoperatively using real-time sensor technology, developed to provide dynamic feedback regarding stability and tibiofemoral load. Th...

Septic non-union (SNU) represents an insidious complication of open fractures. SNU is defined as a clinical and radiological evidence of cessation of fracture healing after 6-8 months of treatment, associated with persistence of clinical, laboratoristic and radiological signs of infection. The infection is mostly caused by bacteria and when it occu...

Aim and objective: Multifocal fractures of the humerus are rare. The aim of our study is to evaluate the effectiveness of surgical treatment and propose a modification to the Maresca-Pascarella classification. A flowchart for surgical treatment is provided. Materials and methods: Thirty-one patients with multifocal humeral fractures were treated...

Introduction: Although Total Knee Arthroplasty (TKA) is a successful procedure, a significant number of patients are still unsatisfied, reporting instability at the mid-flexion range (Mid-Flexion Instability-MFI). To avoid this complication, many innovations, including load sensors (LS), have been introduced. The intraoperative use of LS may facil...

Introduction Viscosupplementation is a well-known strategy for managing early stages knee Osteoarthritis. However, despite its effectiveness in reducing symptoms, it has not yet been found to have an effect on joint cartilage. The aim of this study is to evaluate the clinical efficacy of a new product with gel-like behaviour and its in vivo effects...

Background and aim of the work: since 2003, a series of so called 'micro-posterior' approaches have been developed in the orthopaedic surgery to perform total hip replacement. These techniques present several theoretical advantages compared to the classic postero-lateral approach: reduction in blood loss, post-operative pain, and length of stay bu...

Background and aim of the work: Patellar tendon rupture is a rare complication after Total Knee Arthroplasty (TKA) which often requires surgical treatment. Patients with chronic lesions or tendon degenerations showed good results when treated using autografts or allografts, but these techniques showed poor outcomes at long-term follow-up (FU). Mor...

Background and aim of the work In the orthopaedic and traumatological fields septic non-unions represent a severe complication, hard to manage and treat. Traditionally, the surgical technique consists in to two sequential steps: debridement with administration of local and systemic antibiotics associated with temporary stabilization of the fracture...

Chronic tears of the distal triceps tendon are extremely uncommon lesions. Surgical therapy can be performed with a direct reattachment of the 2 sides of the lesion or—in case of significant tendon retraction—using grafts to fill the resulting gap. Herein, we report a case of a torn distal triceps tendon that occurred in a 33-year-old patient suffe...

Introduction The Pandemic caused by the SARS-CoV-2 has put a strain on the most of health systems all over the world. Many hospitals had to re-organize to deal with the emergency, so that the non-core activities have been suspended or cancelled, raising management problems. The aim of this multicentre study is to report the epidemiological orthopae...

Instability during primary or revision total knee arthroplasty (TKA) in the setting of major bone deficiency and/or soft tissue laxity might require increasing levels of constraint to restore knee stability. Unfortunately, increasing the level of constraint not always correlates with mid-to-long-term satisfactory results. This article reviews the r...

A successful Total Knee Arthroplasty (TKA) requires stability, but rarely, in primary TKA, the use of a prosthesis with more constraint than a posterior- stabilizer (PS) is necessary. The use of Total-Stabilizer (TS) or Constrained Condylar Knee (CCK) prosthesis provides more stability than the a PS one, but presents some theoretical disadvantages,...

he disruption of extensor mechanism is an uncommon event in Total Knee Arthroplasty (TKA). Patellar tendon rupture (PT-R) is one of the most dangerous complication in TKA, having negative impact on the prosthetic joint functions and on the survivorship of implant itself. When an acute total rupture occurs with a good residual tendon quality, surgic...

Instability during primary or revision total knee arthroplasty (TKA) in the setting of major bone deficiency and/or soft tissue laxity might require increasing levels of constraint to restore knee stability. Unfortunately, increasing the level of constraint not always correlates with mid-to-long-term satisfactory results. This article reviews the r...

We report our preliminary results about the effect of HYMOVIS viscosupplementation on the knee cartilage, patients' clinical symptoms and function. The articular cartilage is studied with a 7 Tesla Magnet in the present work.

In questo Poster trattiamo l'utilizzo di una PTG semi-vincolata come primo impianto in pazienti complessi con gravi deformità e instabilità articolare. Riportiamo la nostra esperienza, indicazioni e risultati clinico-strumentali.

A new philosophy of science and medicine had spread throughout the 17th-century Italy: the “Scientific Revolution.” Giovanni Alfonso Borelli (1608–1679) was one of the most charismatic and brilliant scientists of his generation in Europe. He extended to biology the rigorous analytic methods developed by his indirect mentor Galileo in the field of m...

Riportiamo il caso clinico di una pseudoartrosi infetta di femore trattata mediante tecnica chirurgica one-step con l'utilizzo di un chiodo in carbonio rivestito con cemento antibiotico custom made. Viene illustrata la tecnica chirurgica da noi utilizzata e vengono riportati i risultati clinici e strumentali.

Purpose The aim of this retrospective study was to evaluate the subjective and functional outcome of anterior cruciate ligament (ACL) reconstruction with the synthetic Ligament Advanced Reinforcement System (LARS) ligament. Methods Twenty-six patients were reviewed at an average follow-up of 11.6 years. Objective clinical evaluation was performed w...

Introduction Septic arthritis of the hip is a rare condition in adults and its treatment depends on symptoms duration: early onset of infection can be treated with open or arthroscopic debridement, while more aggressive surgery is required when articular damage takes place such as articular resection or total hip replacement (THA). Presentation of...

A successful Total Knee Arthroplasty (TKA) requires stability, but rarely in primary TKA, a prosthesis with more constraint than a posterior-stabilizer (PS) is necessary. In patients with severe varus/valgus deformities with incompetent collateral ligaments or in knees that cannot be adequately balanced after ligaments release, a total-stabilizer (...

Introduction Femoral nerve compression caused by iliopsoas hematoma is a rare complication after hip surgery. To the best of our knowledge, this is the first case after hemiarthroplasty. In this case, iliacus hematoma resulted from spontaneous bleeding favored by anticoagulant therapy. Case Report A 78-year-old female developed left groin pain ass...

Introduction Vascular complications after femoral fixation are rare and not only easy to recognize but also potentially life-threatening. The aim of this case report is to describe how a pseudoaneurysm of the deep femoral artery can complicate an intramedullary nailing after a pertrochanteric fracture and how it can be treated. Case Report We repo...
