A Case-Based Approach to Unicondylar Knee Arthroplasty – Recording

Moderators:  Adolph V. Lombardi, Jr., MD and Kevin D. Plancher, MD
Date recorded: September 25, 2018


This webinar took place on September 25, 2018. It included discussion of partial knee arthroplasty (UKA) and its increased growth in the last several years. Patient selection along with an understanding of which ancillary tests are necessary has generated much discussion on this topic. Medial and Lateral UKA can be a technically demanding procedure for the surgeon if not performed frequently. This symposium provided up to date information allowing for success in performing a unicompartmental knee arthroplasty and dispelled mistaken thoughts as to its outcome and longevity. Illustrative cases and audience participation were important aspects in this webinar.


  • Describe the current indications and understand proper patient selection for medial and lateral unicompartmental knee arthroplasty.
  • Identify the clinical presentation as well as radiographic evaluation and imaging studies which should be obtained preoperatively to determine patient selection for partial knee arthroplasty.
  • Review Tips and tricks for a Medial Unicompartmental Knee Arthroplasty.
  • Review Tips and tricks for a Lateral Unicompartmental Knee Arthroplasty.
  • Plan the execution of a Revision of Partial Knee Arthroplasty to a Total Knee Arthroplasty.
