Sagittal radius of curvature, trochlea design and ultracongruent insert in total knee arthroplasty
Jimmy Wui Guan Ng, Benjamin V. Bloch, and Peter J. JamesKnee
-
Multi radius (MR) total knee arthroplasty (TKA) has been associated with mid-flexion instability.
-
Single radius (SR) TKA may provide better anteroposterior stability through single flexion axis and biomechanical advantage for quadriceps function.
-
Medial pivot (MP) TKA and gradually reducing (GR) radius TKA produce better knee kinematics.
-
Clinical outcomes are equivalent for SR, MR and MP TKA.
-
Short-term studies have shown better clinical outcomes and kinematics for GR TKA.
-
Thinner and narrow anterior flange, deeper trochlea groove and more anatomical trochlea design reduces patellofemoral complications in TKA
-
Ultracongruent inserts provide comparable clinical outcomes to posterior-stabilized TKA and cruciate retaining TKA.
