Ultrasonography for evaluation of hamstring tendon diameter: is it possible to predict the size of the graft?

Objective: Perform the preoperative measurement of the hamstring tendons using ultrasound imaging, validating and correlating the measured value with that found during surgical reconstruction of the ligament.

Methods: A cross-sectional study was carried out with 24 patients who underwent ultrasonographic measurement of the semitendinosus and gracilis muscle tendons and were subsequently submitted to surgical reconstruction of the ACL, with ipsilateral semitendinosus and gracilis tendon grafting.

Results: The patients' ages ranged from 16 to 43 years, with a mean of 24.

Reconstruction of the medial patellofemoral ligament in cases of acute traumatic dislocation of the patella: current perspectives and trends in Brazil.

Objective: To evaluate the approaches and procedures used by knee surgeons in Brazil for treating medial patellofemoral lesions (MPFL) of the knee in cases of acute traumatic dislocation of the patella.

Materials And Methods: A questionnaire comprising 15 closed questions on topics relating to treating MPFL of the knee following acute dislocation of the patella was used. It was applied to Brazilian knee surgeons during the three days of the 44th Brazilian Congress of Orthopedics and Traumatology, in 2012.

Updates in biological therapies for knee injuries: menisci.

The preservation of meniscal tissue is paramount for long-term joint function, especially in younger patients who are athletically active. Many studies have reported encouraging results following the repair of meniscus tears, including both simple longitudinal tears located in the periphery and complex multiplanar tears that extend into the central third avascular region. However, most types of meniscal lesions are managed with a partial meniscectomy.

The effects of exertion on the postural stability in young soccer players.

Objective: : Analyze the effects of physical exertion during a soccer match on the functional capacity and stability of the lower limbs of young soccer players.

Methods: : We analyzed 10 soccer players who underwent functional capacity assessment of the lower limbs by a Hop Test protocol and evaluation of the level of postural stability in the Biodex Stability System (Biodex, Inc., Shirley, NY) before and immediately after a friendly game lasting 45 minutes.

OSTEOCHONDRAL AUTOLOGOUS TRANSPLANTATION FOR TREATING CHONDRAL LESIONS IN THE PATELLA.

Objective: The primary aim of this study was to assess the clinical and functional evolution of patients with total-thickness symptomatic cartilaginous injury of the patellar joint surface, treated by means of osteochondral autologous transplantation.

Methods: This prospective study was conducted from June 2008 to March 2011 and involved 17 patients. The specific questionnaires of Lysholm, Kujala and Fulkerson were completed preoperatively and one year postoperatively in order to assess the affected knee, and SF-36 was used to assess these patients' general quality of life.

ANTERIOR CRUCIATE LIGAMENT INJURY: TREATMENT AND REHABILITATION. CURRENT PERSPECTIVES AND TRENDS.

Objective: The aim of this study was to evaluate the procedures used by knee surgeons in Brazil for treating and rehabilitating anterior cruciate ligament injuries.

Methods: A questionnaire consisting of 21 closed questions was developed, addressing topics relating to treatment and rehabilitation after anterior cruciate ligament reconstruction. The questionnaire was applied to Brazilian knee surgeons during the three days of the 42(nd) Brazilian Congress of Orthopedics and Traumatology in 2010.

UNICOMPARTMENTAL KNEE ARTHROPLASTY: CURRENT PERSPECTIVES AND TRENDS IN BRAZIL.

Objective: The aim of this study was to evaluate the approaches and procedures used by Brazilian orthopedic surgeons for treating osteoarthrosis by means of unicompartmental knee arthroplasty and high tibial osteotomy of the knee.

Methods: A questionnaire with 14 closed questions was developed and applied to Brazilian knee surgeons during the three days of the 43(rd) Brazilian Congress of Orthopedics and Traumatology.

Results: A total of 113 surgeons filled out the questionnaire completely and became part of the sample analyzed.

Introducing 3-dimensional stereoscopic imaging to the study of musculoskeletal anatomy.

The stereoscopic imaging technique is an option for a more realistic understanding of what we normally see in 2 dimensions on paper or on a screen. To produce a 3-dimensional image of an object, it is necessary to register 2 different images of the same object at the same distance and height with the use of cameras that focus on one particular point. A convergence between the left and right images is required for human vision.

CORRELATION BETWEEN TIME UNTIL SURGICAL TREATMENT AND MORTALITY AMONG ELDERLY PATIENTS WITH FRACTURES AT THE PROXIMAL END OF THE FEMUR.

Objective: The primary aim of this study was to analyze the possible association between delay in receiving surgical treatment and mortality among elderly patients with fractures at the proximal end of the femur.

Methods: 269 patients with fractures at the proximal end of the femur (femur neck and intertrochanteric fractures) who were treated surgically at Hospital São Paulo, UNIFESP, São Paulo, between January 2003 and December 2007, were studied. The following attributes were analyzed and compared with the literature relating to this subject: sex, age, type of fracture, classification of the fracture, affected side, synthesis used, trauma mechanism, length of hospitalization, waiting time for surgery, associated comorbidities, hemogram on admission, type of anesthesia, need for blood transfusion, day of the week and season of the year of the fracture.

Surgical versus nonsurgical treatment in first traumatic anterior dislocation of the shoulder in athletes.

Anterior traumatic dislocation is a common problem faced by orthopedic surgeons. After the first episode of shoulder dislocation, a combination of lesions can lead to chronic instability. The management in treatment of young athletes after the first acute anterior shoulder dislocation is controversial.

CORRELATION BETWEEN AVASCULAR NECROSIS AND EARLY STABILIZATION OF PROXIMAL FEMORAL FRACTURES IN CHILDHOOD.

Objective: We developed this study with the aim of evaluating the results from treating patients with proximal femoral fractures, in a series of cases. We sought to observe the influence of the most prevalent complications on the final results after a minimum follow-up of two years. We especially considered the relationship between establishment of avascular necrosis and the time between the accident and the therapeutic intervention.
