Computer-assisted total knee replacement

Computer-assisted revision total knee replacement.

A technique for performing allograft-augmented revision total knee replacement (TKR) using computer assistance is described, on the basis of the results in 14 patients. Bone deficits were made up with impaction grafting. Femoral grafting was made possible by the construction of a retaining wall or dam which allowed pressurisation and retention of the graft. Tibial grafting used a mixture of cor...

Concepts in Computer Assisted Total Knee Replacement Surgery

Total knee arthroplasty (TKA) is commonly considered to be a reliable procedure, with implant survival rates higher than 90% at 10 to 15 years of follow-up. The goal of total knee replacement surgery is to relieve pain and obtain better knee function, those achieved by correct patient selection, pre-operative deformity, implant design, correct surgical technique and patient participation in the...

In June 2001 the senior author (JMS) was approached by representatives of the Stryker organisation with the request that he introduce and evaluate their computer navigation technology (Stryker Corp, Leibinger, Kalamazoo, Michigan), version 1.1, for total kne...

Embolic phenomena during computer-assisted and conventional total knee replacement.

Systemic emboli released during total knee replacement have been implicated as a cause of peri-operative morbidity and neurological dysfunction. We undertook a prospective, double-blind, randomised study to compare the cardiac embolic load sustained during computer-assisted and conventional, intramedullary-aligned, total knee replacement, as measured by transoesophageal echocardiography. There ...
