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.
