Recovery of the Hip Rotation Center with Tantalum in Revision Arthroplasty.

 The objective of the present study is to evaluate the restoration capacity of the hip anatomic rotation center with the use of acetabular tantalum cups, associated or not with addition wedges.  Retrospective analysis of patients undergoing hip arthroplasty revision using tantalum between June 2013 and April 2017. The abduction angle of the acetabular component and the horizontal and vertical distances of the component to the center of anatomical rotation of the hip were evaluated.

Reliability of the Arthroscopic Classifications of Hip Chondral Lesions.

 To evaluate the inter- and intraobserver reliability of the Outerbridge, Beck, and Haddad classifications for acetabular joint cartilage lesions through the arthroscopic procedure.  A total of 60 hip arthroscopy videos were evaluated twice by 4 surgeons at 2 different times to assess the inter- and intraobserver reproducibility of the classifications, and the data was analyzed by means of the weighted Cohen Kappa index.  The mean weighted Kappa values in the interobserver assessment of the Outerbridge, Beck, and Haddad classifications were, respectively, 0.

Evaluation of the ischiofemoral space: a case-control study.

Objective: To determine the size of the ischiofemoral space (IFS) and quadratus femoris space (QFS) in patients with and without ischiofemoral impingement (IFI).

Materials And Methods: Case-control study including consecutive patients submitted to magnetic resonance imaging (MRI) of the hip joint during a three-month period. Patients with deep gluteal pain who tested positive for IFI on at least one clinical test and showed signal changes in the quadratus femoris muscle on MRI were categorized as having a confirmed diagnosis of IFI.

Piriformis Pyomyositis in a Patient with Kikuchi-Fujimoto Disease - A Case Report and Literature Review.

Primary pyomyositis is a deep bacterial infection of the skeletal muscle. If left undiagnosed and untreated, the infection spreads, leading to sepsis, septic shock, and even death. The authors report a 23-year-old female presenting with piriformis pyomyositis during a treatment for Kikuchi-Fujimoto disease.

Determining Reliability of Arthroscopic Classifications for Hip Labral Tears.

Objective: Evaluate interobserver and intraobserver reliability of hip arthroscopic classifications for labral tears.

Design: Retrospective diagnostic study of nonconsecutive patients.

Setting: Institutional study.

Clinical outcomes of arthroscopic repair of acetabular labral tears.

Purpose: To evaluate the primary clinical outcomes of arthroscopic labral repair.

Methods: All patients who underwent arthroscopic repair of the acetabular labrum performed by a senior surgeon between October 2010 and December 2013 were invited to participate in this prospective study. Patients included were those who had a preoperative diagnosis of labral tears, a lateral centre edge greater than 25° and a labral tear believed to be suturable during the intraoperative evaluation.

Efficacy evaluation of a protocol for safe hip surgery (total hip arthroplasty).

Objective: To propose a multidisciplinary protocol to standardize the care of patients undergoing total hip arthroplasty (THA) and evaluate it effectiveness after implementation.

Methods: Retrospective evaluation of 95 consecutive patients undergoing THA divided into two groups, one group of 47 patients operated before the protocol implementation and 48 after.

Results: Assessing the re-admission rate, among 47 patients evaluated prior to implementation of the protocol, seven (14.

Diffuse pigmented villonodular synovitis in knee joint: diagnosis and treatment.

Pigmented villonodular synovitis is a rare proliferative condition of the synovium. Although the condition can present in any joint, the knee is the most commonly affected site. Despite being a benign condition, pigmented villonodular synovitis is often aggressive, with marked extra-articular extension in some cases.

A New Technique for Surgical Treatment of Proximal Hamstring Tendinopathy in a Triathlon Athlete.

Introduction: Proximal hamstring tendinopathy (PHT) is the result of chronic overload caused by repetitive eccentric contraction. Surgical treatment becomes an option for patients with chronic symptoms that do not respond to conservative treatment.

Case Report: This report describes a case of a 48-year-old man, an amateur triathlete, with deep gluteal pain in the left hip for 12 months, leading to a decline in sports performance.
