Nonoperative Treatment for Partial Ruptures of the Lateral Collateral Ligament Occurring in Combination With Complete Ruptures of the Anterolateral Ligament: A Common Injury Pattern in Brazilian Jiu-Jitsu Athletes With Acute Knee Injury.

Background: Combined partial lateral collateral and complete anterolateral ligament (PLCCALL) injuries are a specific injury pattern seen in Brazilian jiu-jitsu (BJJ) because of the knee varus-flexion mechanism that frequently occurs during grappling.

Purpose/hypothesis: The purpose of this study was to evaluate the incidence of this injury pattern in a series of BJJ athletes with an acute knee injury and to evaluate clinical and functional outcomes after nonoperative management at a minimum follow-up of 1 year. Our hypotheses were that PLCCALL injuries are common in BJJ and that nonoperative treatment is associated with excellent clinical outcomes and return to the preinjury level of sport.

Range of motion predictability after total knee arthroplasty with medial pivot prosthesis.

Objective: To assess whether there the final range of motion (ROM) results achieved by patients undergoing total knee arthroplasty (TKA) with prosthesis using Medial Pivot design are predictable.

Methods: Between January and August of 2014, 155 patients with primary osteoarthritis of knee who underwent TKA using the prosthesis ADVANCE Medial Pivot were prospectively assessed. All ROM measures were made and recorded before, during, and after surgery.

Richness, composition and trophic groups of an avian community in the Pernambuco Endemism Centre, Alagoas, Brazil.

In northeastern Brazil, the reduction of the natural forest cover to a series of small, isolated fragments has had negative consequences for the local avian fauna, in particular, a loss of the more specialized species, while the populations of some generalists have tended to increase. The present study focuses on the composition and trophic groups of a bird community on a farm in the northeastern Brazilian state of Alagoas. Monthly surveys were conducted between November 2008 and October 2009, based on mist-netting and systematic observations.
