Learn the First Stage Revision Total Knee Replacement for Acute Prosthetic Joint Infection (Zimmer Biomet articulating spacer) surgical technique with step by step instructions on OrthOracle. Our e-learning platform contains high resolution images and a certified CME of the First Stage Revision Total Knee Replacement for Acute Prosthetic Joint Infection (Zimmer Biomet articulating spacer) surgical procedure.

Periprosthetic joint infection (PJI) is a devastating complication of prosthetic joint replacement, accounting for 22.5% of 60,671 of revision total knee arthroplasties performed in the UK between 2003-2017.[i]

Surgical management involves identification of the infecting pathogens and optimisation of the host prior to major surgery, which may involve debridement and implant retention, or a single or two-staged revision procedure. Staged revision surgery remains the gold standard of care. At the first stage the prosthetic components are explanted and the involved soft-tissues are radically debrided. The joint is temporarily stabilised with either an articulating cement spacer, as in this case, or non-articulating spacer for approximately 3 months. At the second stage, following repeat debridement, the joint is reconstructed.

The articulating spacer (StageOne Cement Spacer Molds, Zimmer Biomet) permit the delivery of local antibiotics after the initial explantation and debridement whilst preserving some joint motion thus improving patient function and satisfaction between stages and preserving soft-tissue planes for the second stage.

  • Each operation and the questions associated become a named course in the CPD section
  • The operative technique itself is read as a lesson as is any company implant information if this is being assessed.
  • You’ll need to tick the box to confirm this has been done and can do this immediately if you have already read the op tech.
  • The vast majority of operations have a 10-15 MCQ quiz covering all aspects of the decision making and the technique
  • There are four possible answers of which one is correct (or on occasion more correct) than the others.
  • There are additional quiz modules on the surgical steps, the implants and problem cases being added continually
  • The course is completed once all the lessons are read and quizzes submitted and passed.
  • On successful completion of each quiz you will receive validated CPD points that add to the certificate in your CPD folder.
  • Your dashboard also will contain a record of the time you have spent logged onto and using the site.
  • The timer suspends after 5 minutes though if there is no activity.
  • When you restart you will resume at the same point in the module.
  • Once you have completed each quiz you will need to feedback on the module first then click “submit” and your paper will be marked.
    The pass mark is 75%.
  • If you fall below this level you will be directed back to re-read the slides where you’ve tripped up.
  • Once these have been read you can re-do just the questions you failed on.
  • Once you have passed the quiz you can return at a future stage & resit .

CPD Points:

  • Operation Quiz – 1 CPD point
  • Surgical steps Quiz – 1/4 CPD point
  • Implants Quiz – 1/4 CPD point
  • Problem case Quiz – 1/2 CPD point

One CPD point equates to one hour of academic activity

COURSE

Welcome to the Professional Development question section. The objective of taking these tests is to demonstrate that you have understood all aspects of the assessment and management of patients requiring surgical intevention. On successful completion you will receive a certificate accredited by both the Royal College of Surgeons of both England and Edinburgh as well as the British Orthopaedic Association.
