The JBJS Quiz of the Month is a collection of 10 relevant questions from each orthopaedic subspecialty. The questions are drawn from JBJS Clinical Classroom, which houses over 4,500 questions and 3,100 learning resources. Take the Quiz to see how you score against your peers!

NOTE: This quiz does not earn users CME credits. The questions must be answered within Clinical Classroom to earn CME credits.

When compared with posterior-stabilized total knee arthroplasty, which of the following is an advantage of cruciate-retaining total knee arthroplasty?
  • Improved range of motion
    • There is no evidence to support improved range of motion of cruciate-retaining versus cruciate-sacrificing total knee arthroplasty.

  • More required bone resection when using a measured resection technique
    • Gap balancing and measured resection techniques can be used with either cruciate-retaining or cruciate-sacrificing total knee arthroplasty.

  • Enhanced proprioception as evidenced by improved functional outcome scores
    • Some authors do suggest that there is increased proprioception with cruciate ligament retention; however, there is no evidence to support improved functional outcome scores.

  • Maintenance of the anatomic joint line
    • Over-resection of the distal aspect of the femur and use of a gap-balancing technique risks joint line elevation in posterior stabilized knee implants.
