Short-term clinical and radiological outcomes of a guided-motion bicruciate-substituting total knee system in Chinese patients

Abstract

Introduction: The JOURNEY II Bi-Cruciate substituting total knee system is a second-generation guided-motion knee implant. We looked at the short-term clinical and radiological outcomes in Chinese patients. Methods: Data for 110 primary total knee arthroplasties (TKAs) performed in three hospitals under one university health system were reviewed. The pre- and post-operative knee and lower limb standing radiographs were used to measure the change in lower limb alignment and component positioning. Knee Society Score (KSS) and Knee Society Function Score (KFA) were used for clinical assessment. Complications were documented. Results: A total of 110 TKAs were performed in 97 patients (71 females, 26 males). The average age was 68.7 years (range, 49-87 years). Patellae were not resurfaced. The mean follow-up time was 1.5 years. At the latest follow-up, KSS and KFA showed significant improvement compared with the preoperative value. The radiological assessments showed satisfactory restoration of mechanical alignment and components positioning. There was no major complication or revision documented. Conclusion: The second-generation guided-motion bicruciate-substituting total knee implant demonstrated satisfactory short-term outcomes in Chinese patients.
