Higher rates of fully preserved posterior cruciate ligament in total knee arthroplasty using a double tibial cut: a prospective randomized controlled trial
PurposeIn cruciate retaining total knee arthroplasty, posterior cruciate ligament damage may occur during tibial cutting. A prospective randomized...

Knee joint laxity is restored in a bi-cruciate retaining TKA-design
PurposeThe goal is to evaluate the passive stability of a bicruciate retaining, cruciate retaining and bicruciate substituting TKA design in relation...

PCL preservation or sacrifice does not influence clinical outcomes and survivorship at mid-term follow-up of a J-curve CR total knee replacement with a medial congruent liner and a functional coronal alignment
BackgroundIn recent years, increasing interest has arisen for medial pivoting TKA implants, designed to mimic the physiological knee kinematics,...

Biomechanics and Outcomes of Modern Tibial Polyethylene Inserts
Purpose of ReviewThere have been many attempts to use variations in tibial polyethylene design to better recreate normal knee kinematics in the total...
-
Comparable level of joint awareness between the bi-cruciate and cruciate retaining total knee arthroplasty with patient-specific instruments: a case-controlled study
PurposeBi-cruciate-retaining total knee arthroplasty (BCR-TKA) is recognized as an alternative to the cruciate-retaining total knee arthroplasty...

Retention of the posterior cruciate ligament stabilizes the medial femoral condyle during kneeling using a tibial insert with ball-in-socket medial conformity
PurposeResecting the posterior cruciate ligament (PCL) increases posterior laxity and increases the flexion gap more than the extension gap in the...
-
Short-term clinical results of bicruciate-retaining total knee arthroplasty using personalized alignment
BackgroundBicruciate-retaining (BCR) prosthesis has been introduced to recreate normal knee movement by preserving both the anterior and posterior...

Changes in femoral rollback and rotation with increasing coupling in knee arthroplasty—a biomechanical in-vitro study
BackgroundAfter total knee arthroplasty, 10–30% of patients still complain about knee pain, even after exact positioning of the components. Altered...
-
Unrestricted kinematic alignment corrects fixed flexion contracture in robotically aligned total knees without raising the joint line in extension
PurposeMechanically Aligned Total Knee Arthroplasty (MA TKA) typically addresses fixed flexion contractures (FFC) by raising the joint line during...

Factors that impact the patellofemoral contact stress in the TKA: a review
Abnormal retro patellar stress is believed to contribute to patellofemoral complications after total knee arthroplasty (TKA), but the causal link...
-
Prediction of wear performance in femoral and tibial conformity in patient-specific cruciate-retaining total knee arthroplasty
BackgroundArticular surface curvature design is important in tibiofemoral kinematics and the contact mechanics of total knee arthroplasty (TKA). Thus...

Early functional outcomes after condylar-stabilizing (deep-dish) versus standard bearing surface for cruciate-retaining total knee arthroplasty
AimsThe primary study aim was to compare early knee-specific function of patients undergoing cemented total knee arthroplasty (TKA) with either a...
-
Functional alignment in total knee arthroplasty best achieves balanced gaps and minimal bone resections: an analysis comparing mechanical, kinematic and functional alignment strategies
PurposeKey concepts in total knee arthroplasty include restoration of limb alignment and soft-tissue balance. Although differences in balance have...

Posterior-stabilized total knee arthroplasty kinematics and joint laxity: A hybrid biomechanical study
BackgroundPosterior-stabilized (PS)-total knee arthroplasty (TKA) arose as an alternative to cruciate-retaining (CR)-TKA in the 1970s. Since then, it...
