摘要Introduction: Prevalence of total knee arthroplasty is projected to substantially rise. Approximately 20% of patients remain unsatisfied with complaint of knee pain and poor functional outcome, prompting development of new surgical techniques. Current improvement in implant design includes preserving the PCL (Cruciate Retaining) or both the ACL and PCL (Bi-Cruciate Retaining). Replication of the normal kinematics and proprioception by preserving the cruciate ligaments with the aid of robotics may pave way in improving patient satisfaction.
Methods: This was a retrospective case-controlled study. The kinematics analysis includes gait cycle, sit-to-stand, and stairs. Measured outcomes include flexion-extension, varus-valgus, and internal-external rotation. Proprioception was measured by an isokinetic dynamometer at thirty and forty degrees. Functional outcomes were measured by the Knee Society Score and Knee Function Scores.
Results: 15 patients each were recruited. All of them were robotic-assisted. The maximum range of flexion and the range of flexion to extension during walking was significantly larger in BCR knees. There was a trend of better knee society score at early post-op and knee function score at 6 months post-op in BCR. The proprioception of BCR tends to better as well.
Discussion and conclusion: Preserving the anterior cruciate ligament in bi-cruciate retaining knees is preferential in kinematics and proprioception with promising functional scores.
