Abstract
- PURPOSE
The purpose of this study is to compare the change of joint line and patellar position between posterior crucate ligament-retained and posterior cruciate ligament-sacrificed total knee arthroplasty. MATERIALS AND METHODS: Fifty posterior crucate ligament-retained and fifty posterior cruciate-sacrificed total knee arthroplasties were evaluated to compare the joint line height from tibial tuberosity, patella bone height from joint line, patella articular height from joint line, patella bone height from tibial tuberoisty and patella articular height from tibial tuberosity. The measurements were assessed preoperatively and postoperatively. RESULTS: No difference in joint line height from tibial tuberosity, patellar bone height from joint line, patellar articualr height from joint line, patellar bone height from tibial tuberosity and patellar articular height from tibial tuberosity were found with either design (p>0.05). CONCLUSION: This study demonstrates that the resection of the posterior cruciate ligament can be one of the preferable method to increase the flexion gap without influencing the joint line in Total knee arthroplasty.
