The Effectiveness of Periarticular Anesthetic Infiltration in Postoperative Analgesia of Total Hip Arthroplasty.

 The present study aims to evaluate the effectiveness of the periarticular hip infiltration technique in the postoperative period of total hip arthroplasty.  This is a randomized double-blind controlled clinical trial in patients with femoral neck fractures or hip osteoarthritis submitted to a total hip arthroplasty at our institution. The periarticular infiltration technique consisted of the administration of an anesthetic (levobupivacaine) and a steroid (dexamethasone) agent in the nociceptor-rich tissues of the hip after orthopedic implants placement.

Arthroscopic Treatment of Femoroacetabular Impingement in Slipped Capital Femoral Epiphysiolysis: A Case Report.

Slipped capital femoral epiphysiolysis (SCFE) may result in femoroacetabular impingement (FAI) of the hip in up to one third of the cases. Residual deformity of the cam-type, or "pistol-grip", is associated with chondrolabral injury, resulting in pain, functional disability, and early osteoarthritis. The arthroscopic treatment with osteochondroplasty proved to be beneficial in a selected case of FAI secondary to SCFE.

Evaluation of Nutritional Status and Correlation with Postoperative Complications in Elderly Patients Submitted to Surgical Treatment of Proximal Femoral Fractures.

 This study aims to evaluate and correlate the nutritional status with potential complications during the immediate postoperative period of elderly patients surgically treated for proximal femoral fractures.  A prospective, cross-sectional analytical study with a quantitative approach, targeting patients aged 60 years old or more who were admitted to a hospital in Amazonas, Brazil, for surgical treatment of proximal femoral fractures. Surgical complications during the immediate postoperative period and their relationship with the nutritional status of the patient were determined using the mini nutritional assessment (MNA); in addition, the lymphocyte numbers and serum albumin levels were determined and correlated with the length of hospital stay.

Primary lipoma arborescens of the knee.

Lipoma arborescens is a rare and benign intra-articular lesion of unknown etiology; it is characterized by synovial villous proliferation and sub-synovial connective tissue replacement by mature fatty tissue. It is part of the differential diagnosis in patients with an articulation affected by a slow, progressive, and chronically inflamed affection. We report primary knee involvement in a patient without significant articulate antecedents.

Internal fixators: a safe option for managing distal femur fractures?

Objective: Evaluate safety and reliability of internal fixator for the treatment of intra-articular and periarticular distal femur fractures.

Methods: Retrospective data evaluation of 28 patients with 29 fractures fixed with internal fixator was performed. There was a predominance of male patients (53.

Updates in biological therapies for knee injuries: bone.

Bone is a unique tissue because of its mechanical properties, ability for self-repair, and enrollment in different metabolic processes such as calcium homeostasis and hematopoietic cell production. Bone barely tolerates deformation and tends to fail when overloaded. Fracture healing is a complex process that in particular cases is impaired.

Varization open-wedge osteotomy of the distal femur: comparison between locking plate and angle blade plate constructs.

Purpose: Biomechanical properties of locking plate and angle blade plate constructs in opening-wedge distal femur osteotomy were compared, with special attention to the impact of opposite cortex breakage and buttressing.

Methods: Forty-eight synthetic femora underwent a lateral opening-wedge distal femur osteotomy, which was fixed either with a locking plate or with an angle blade plate. Two main groups were constituted based on the integrity of the opposite medial cortex-intact medial cortex and fractured medial cortex (FMC).
