A number of postoperative complications of navigated total knee arthroplasty have been discussed in the literature, including tracker pin site infection and fracture. In this paper we discuss the low postoperative complication rate in a series of 3100 navigated total knee arthroplasties and the overall complication rate in a systematic analysis of the literature. 3100 consecutive patients with navigated total knee arthroplasties from 2001 to 2016 were retrospectively evaluated for complications specific to navigation. We discuss the two cases of postoperative fracture through tracker pin sites that we experienced and compare this systematically to the literature.Abstract
Methods
Genu recurvatum is a deformity rarely seen in patients receiving total knee arthroplasty. This deformity is defined as hyperextension of the knee greater than 5°. The incidence of recurvatum has been cited in the literature as less than 1%. The purpose of this study was to report data on 1510 consecutive total knee replacements (TKR) with navigation to demonstrate that the incidence of genu recurvatum is higher than what is cited in the literature.Introduction
Purpose
The concept and method of repeatedly connecting an extracorporeal blood pump to produce elevated pancycle inflow pressures to ischaemic limbs is presented. The aim of this study was to determine if intermittent increased perfusion would improve the clinical picture in peripheral arterial disease. Animal studies—to determine the safety and efficacy of the pumping and the access device were performed on 12 sheep. Following successful completion of that study, pilot studies of 18 patients were treated using the Peripheral Access Device (PAD) and Hypertensive Extracorporeal Limb Hyperperfusion (HELP). Treatment was offered to patients who had no other alternative than major amputation. Patients were treated for less than 100 hours of total pumping, broken over three or less treatment periods over approximately one week. Improvement was measured by pain scores, clinical examination and digital thermography.Introduction
