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.

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.
