Abstract:
Cruciate-retaining total knee arthroplasty has had high success rates but does not always have optimal functional outcomes. The purpose of this study was to compare 2 polyethylene inserts of varying constraint that were used in a new cruciate-retaining total knee arthroplasty design to determine whether differences were found in clinical or functional outcomes. The use of the newer cruciate-retaining total knee arthroplasty design showed comparable results with both polyethylene inserts at short-term follow-up. The cruciate-retaining design had a greater than 99% survivorship, although further study is needed to make assessments regarding long-term functional results and outcomes.
