Randomized Controlled Trial Comparative StudyMost effective regimen of tranexamic acid in knee arthroplasty: a prospective randomized controlled study in 240 patients.
The antifibrinolytic tranexamic acid reduces surgical blood loss, but studies have not identified an optimal regimen. ⋯ Single-dose tranexamic acid did not give effective results. The two-dose regimen of POIO was the least amount necessary for effective results. When compared against the control, this regimen produced reduction of drain loss and total blood loss, whereas the IOPO regimen did not. The three-dose regimen of POIOPO produced maximum effective reduction of drain loss and total blood loss.

Editorial ReviewReviewing for clinical orthopaedics and related research.
Peer review in science was established in the 17th Century and while not without detractors and some controversy, has been a mainstay of high-quality scientific publications ever since. Most believe peer review adds substantially to the value of papers that achieve publication. However, in practice, peer review can be practiced with varying degrees of rigor and the value of the review depends on rigor. ⋯ In this brief review I outline such key questions. An invitation to review is an honor and reflects the confidence of the editor in the reviewer's expertise and accomplishments. Given proper reviews and recommendations, the majority of authors believe peer review adds great value to their papers and the reviewer makes contributions to the community and their own knowledge.

Neer modification of open Bankart procedure: what are the rates of recurrent instability, functional outcome, and arthritis?
Neer modified the Bankart procedure by combining a superoinferior capsular shift with the labral reattachment. The theoretical advantages of the modification were that such a procedure would restore the patient's anatomy and also treat the repeated capsular stretching encountered in anteroinferior instability without limiting external rotation and, thereby reducing the risk of arthritis. ⋯ The open Bankart procedure modified by Neer provided high function scores but a relatively low rate of return to sport and high rate of recurrent instability. Our rate of recurrent instability, similar to that obtained with arthroscopic Bankart procedures, has prompted us to abandon the open procedure.

High survival of dome pelvic osteotomy in patients with early osteoarthritis from hip dysplasia.
The Chiari osteotomy reportedly has a 60% to 91% survival rate at a minimum 20 years followup. The dome pelvic osteotomy (DPO) has the advantage of allowing a larger weightbearing surface, and congruity in the sagittal plane presumably would reduce the joint contact stress and perhaps increase longevity. ⋯ DPO is a reasonable treatment option for patients with DDH and prearthritis or early osteoarthritis, with high survival at greater than 25 years.

Triple innominate osteotomy for Legg-Calvé-Perthes disease in children: does the lateral coverage change with time?
Triple innominate osteotomy (TIO) is one of the modalities of surgical containment in Legg-Calvé-Perthes disease (LCPD). However, overcoverage with TIO can lead to pincer impingement. ⋯ TIO resulted in femoral head containment in all cases. Lateral acetabular coverage changed during the growing years in all patients. Surgical correction beyond 44° of CE angle and -6° of ARA should be avoided to prevent pincer morphology later.
