“…Although both cruciate ligaments were preserved in all BCR TKA systems, lateral pivoting during gait was only observed in 60% of patients with this BCR TKA system. This may suggest that, in addition to the cruciate ligaments, different articular polyethylene surface designs in these BCR TKA systems may, in part, play an important role in determining in vivo knee contact kinematics during gait.…”

Bi-cruciate retaining (BCR) total knee arthroplasty (TKA) design preserves both anterior and posterior cruciate ligaments with the potential to restore normal posterior femoral rollback and joint kinematics. Abnormal knee kinematics and "paradoxical" anterior femoral translation in conventional TKA designs have been suggested as potential causes of patient dissatisfaction. However, there is a paucity of data on the in vivo kinematics and articular contact behavior of BCR-TKA. This study aimed to investigate in vivo kinematics, articular contact position, and pivot point location of the BCR-TKA during gait. In vivo kinematics of 30 patients with unilateral BCR-TKA during treadmill walking was determined using validated dual fluoroscopic imaging tracking technique. The BCR-TKA exhibited less extension than the normal healthy knee between heel strike and 48% of gait cycle. Although the average external rotation trend observed for BCR TKA was similar to the normal healthy knee, the range of motion was not fully comparable. The lowest point of the medial condyle showed longer anteroposterior translation excursion than the lateral condyle, leading to a lateral-pivoting pattern in 60% of BCR TKA patients during stance phase. BCR-TKA demonstrated no statistical significant differences in anterior-posterior translation as well as varus rotation, when compared to normal healthy knees during the stance phase. However, sagittal plane motion and tibiofemoral articular contact characteristics including pivoting patterns were not fully restored in BCR TKA patients during gait, suggesting that BCR TKA does not restore native tibiofemoral articular contact kinematics.

“…However, another aspect to consider that could influence kinematics is the implant design, which has been significantly improved with the last anatomic models. Several ex vivo studies demonstrated that BCR implants could preserve the screw-home mechanism, maintaining a more anterior femorotibial contact point, increasing the axial rotation and the posterior displacement through flexion in contrast to the ACL-sacrificing design and similar to a native knee[ 39 - 42 ]. However, in addition to ACL preservation, some authors have highlighted the importance of tibial geometry in the restoration of the physiological knee kinematics[ 41 , 43 ].…”

Primary total knee arthroplasty (TKA) is a widespread procedure to address end stage osteoarthritis with good results, clinical outcomes, and long-term survivorship. Although it is frequently performed in elderly, an increased demand in young and active people is expected in the next years. However, a considerable dissatisfaction rate has been reported by highly demanding patients due to the intrinsic limitations provided by the TKA. Bicruciate-retaining (BCR) TKA was developed to mimic knee biomechanics, through anterior cruciate ligament preservation. First-generation BCR TKA has not gained popularity due to its being a challenging technique and having poor survival outcomes. Thanks to implant design improvement and surgeon-friendly instrumentation, second-generation BCR TKA has seen renewed interest. This review will focus on surgical indications, kinematical basis, clinical results and latest developments of second-generation BCR TKA.

“…BCR implants have shown a more physiologic anterior femorotibial contact point and a greater posterior translation in motion compared to ACL-sacrificing implants [7][8][9][10][11]. Recently, Peersman et al [8] showed that changes by removal of the conforming meniscus and cartilage have more impact on tibiofemoral kinematics than different inlay sizes of a BCR TKA. However, they confirmed close to normal knee kinematics for BCR-TKA.…”
