Is load control necessary to produce physiological AP displacement and axial rotation in wear testing of TAR?

The International Standard Organization, ISO 22622, specifies two options for joint wear simulator evaluation of total ankle replacements (TARs): load-controlled and displacement-controlled. In the present study, the load-controlled testing parameters were applied to cadaveric specimens to quantify and compare the observed sagittal translations and axial rotations to those specified under the displacement-controlled option. Twelve cadaveric specimens were stripped of extraneous tissues, keeping surrounding ankle ligaments.

Incidence and predictors of early complications following primary and revision total ankle arthroplasty.

Background: Total ankle arthroplasty (TAA) offers an effective option for end-stage osteoarthritis. The incidence and preoperative risk factors for early adverse events (AEs) following primary and revision TAA may be useful information for providers.

Methods: A large database was queried from 2010 to 2016 to identify 905 patients of whom 818 underwent primary TAA (90.

A Clinical Nurse's Walk Through Research: Relieving Postoperative Urinary Urgency.

A clinical nurse at a small community hospital recognized a need to help patients with urinary urgency following laparoscopic-assisted vaginal hysterectomy. The subsequent continuous quality improve- ment project is described.

Large BM Intra-Articular Allograft.

Posttraumatic tibiotalar arthritis is a challenging problem in young, active patients. Many of these patients do not want to pursue ankle arthrodesis after they fail conservative treatment measures, as they wish to preserve joint motion. Osteochondral shell allograft arthroplasty has been described as a reasonable alternative for treating these patients.

Incidence of Preoperative Deep Vein Thrombosis in Calcaneal Fractures.

Objectives: This study examined the incidence and risk factors of preoperative deep vein thrombosis (DVT) in patients presenting to an outpatient setting with an isolated calcaneal fracture.

Design: Retrospective chart review.

Setting: All patients included in the study presented to the treating surgeon at a Level I trauma center with isolated calcaneal fractures as an outpatient between 2005 and 2013.

Intraoperative and perioperative complications during revision arthroplasty for salvage of a failed total ankle arthroplasty.

Background: Revision of a failed total ankle arthroplasty (TAA) remains a challenge. Advances in total ankle implant design have renewed interest in revision TAA as an alternative to ankle arthrodesis or amputation in the management of a failed TAA. The purpose of our study was to review a series of failed Agility TAA revised to INBONE II TAA and identify reasons for revision as well as perioperative complications.
