Proximal avulsion of the hamstring in young athlete patients: a case series and review of literature.

Hamstring injuries are a frequent occurrence of athletes, leading to a stop in practice and long-term alterations in sports performance. About 12% of these lesions involve avulsion at the level of the proximal insertion that can be complete (about 6%) or partial. Starting from an epidemiological and treatment evaluation of these lesions in literature, the aim of this study was to examine the functional outcomes and the rate of "return to play" in a population composed of athletes of various levels who have undergone surgery to reinsert the hamstring muscles at the ischial insertion, for a complete detachment of one or more tendon heads.

First Italian Experience with the Oxinium Metal-Backed Fixed-Bearing Medial Journey II Unicompartmental Knee System: Promising Short-Term Outcomes of 145 Cases.

From the central pivot to the peripheal knee injuries in the skier: a narrative review.

The improvement in the technology in the last 20 years has showed its main effect on the increase of the speed in the curves, thus leading to a rise of knee injuries. In fact, the most injured zone of the body was the knee (35,6 %) and the distal part of the lower body (11,5%), with ACL lesion as the most frequent diagnosis (49% of all the injuries to the knee) due to a trauma in valgus and external rotation in most of cases. The MCL is involved in the 15-20% of the cases while the LCL in only the 4,2% of the patients.

Italian consensus statement for the use of allografts in ACL reconstructive surgery.

Purpose: Graft choice for primary anterior cruciate ligament reconstruction (ACL-R) is debated, with considerable controversy and variability among surgeons. Autograft tendons are actually the most used grafts for primary surgery; however, allografts have been used in greater frequency for both primary and revision ACL surgery over the past decade. Given the great debate on the use of allografts in ACL-R, the "Allografts for Anterior Cruciate Ligament Reconstruction" consensus statement was developed among orthopedic surgeons and members of SIGASCOT (Società Italiana del Ginocchio, Artroscopia, Sport, Cartilagine, Tecnologie Ortopediche), with extensive experience in ACL-R, to investigate their habits in the use of allograft in different clinical situations.

Role of MRI in predicting meniscal tear reparability.

Objective: To elucidate the role of MRI in predicting meniscal tear reparability according to tear type and location in relation to vascular zones.

Materials And Methods: In this retrospective study, two readers evaluated 79 pre-surgical MRIs of meniscal tears arthroscopically treated with meniscectomy or meniscal repair. Tears were classified according to type into vertical, horizontal, radial, complex, flaps and bucket handle and were considered reparable if the distance measured from the tear to the menisco-capsular junction was less than or equal to 5 mm.

Platelet-rich plasma in the treatment of acute hamstring injuries in professional football players.

Purpose: muscle injuries have a high incidence in professional football and are responsible for the largest number of days lost from competition. Several in vitro studies have confirmed the positive role of platelet-rich plasma (PRP) in accelerating recovery and in promoting muscle regeneration, and not fibrosis, in the healing process. This study examines the results of intralesional administration of PRP in the treatment of primary hamstring injuries sustained by players belonging to a major league football club.

Non-surgical treatments for the management of early osteoarthritis.

Non-surgical treatments are usually the first choice for the management of knee degeneration, especially in the early osteoarthritis (OA) phase when no clear lesions or combined abnormalities need to be addressed surgically. Early OA may be addressed by a wide range of non-surgical approaches, from non-pharmacological modalities to dietary supplements and pharmacological therapies, as well as physical therapies and novel biological minimally invasive procedures involving injections of various substances to obtain a clinical improvement and possibly a disease-modifying effect. Numerous pharmaceutical agents are able to provide clinical benefit, but no one has shown all the characteristic of an ideal treatment, and side effects have been reported at both systemic and local level.

Clinical and radiographic outcomes of a trabecular titanium™ acetabular component in hip arthroplasty: results at minimum 5 years follow-up.

Osteochondritis dissecans of the talus.

Osteochondritis dissecans (OCD) is an acquired idiopathic lesion of subchondral bone that can produce delamination and sequestration with or without articular cartilage involvement and instability. The cause of OCD is still debated: the most recognized etiology is the occurrence of repetitive micro-traumas associated with vascular impairment, causing progressive ankle pain and dysfunction in skeletally immature and young adult patients. Ankle OCD is classically located in the medial part of the talus, while lateral and posterior involvement is less frequent.

Osteochondritis dissecans of the knee.

Osteochondritis dissecans (OCD) of the knee is a common cause of knee pain and dysfunction among skeletally immature and young adult patients. OCD is increasingly frequently seen in pediatric, adolescent and young adult athletes. If it is not recognized and treated appropriately, it can lead to secondary osteoarthritis with pain and functional limitation.

Renal transplantation in children weighing <15 kg: does concomitant lower urinary tract dysfunction influence the outcome?

Background: We reviewed our experience with renal transplantation (RTx) in children weighing <15 kg to determine if the presence of lower urinary tract dysfunction (LUTD) influenced the outcome.

Methods: Between 1987 and 2012, 68 RTx were performed in patients weighing less than 15 kg, including 17 with associated LUTD and 51 without. We detailed the lower urinary tract management in these patients, and compared graft survival rates and estimated clearance 12 and 60 months after RTx between groups.
