Table 2 Post-operative patient-reported outcome scores and knee extension and flexion for the B-in-S MC + PCL insert. Values presented are the median (interquartile-range) and mean ± standard deviation (range)

From: A new tibial insert design with ball-in-socket medial conformity and posterior cruciate ligament retention closely restores native knee tibial rotation after unrestricted kinematic alignment
