|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.
