“…Twenty-two knees in 21 patients (5.6%) were revised and the most common causes where polyethylene wear, aseptic loosening of the femoral or tibial component (seven revisions) and infection (four revisions)[ 31 ]. Ries et al [ 50 ] showed mechanical failure in 20 first-generation BCR TKAs that required revision; the authors retrieved 16 porous coated cementless Ti-6Al-4V tibial trays (BioPro, Port Huron, MI, United States), 2 cast CoCr tibial trays (BioPro) , and two all polyethylene tibial implants (Geomedic; Howmedica, Rutherford, NJ, United States). Four failure implant ways were identified, namely fracture of the anterior tibial tray or bridge (fatigue fracture), insert dissociation, UHMWPE wear, and tibial component loosening[ 21 ].…”

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.
