Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.Abstract Purpose Functional alignment (FA) in total knee arthroplasty (TKA) prioritizes soft tissue balancing and anatomical restoration without systematic correction to neutral alignment. Most studies have focused on varus deformity, with little evidence available about FA in valgus deformity. The hypothesis of the present study was that FA in robotic‐

Theoretical and Applied Mechanics Letters, 2023 Researchers have proposed various linkage mechanisms to connect knee and ankle joints for above-knee prostheses, but most of them only offer natural walking. However, studies have shown that people assume a squatting posture during daily activities. This

Acute, recurrent total knee dislocation: Polyethylene dislocation and malreduction
Arthroplasty Today, 2015 A 62-year-old man underwent total knee arthroplasty using a mobile-bearing prosthesis. Four days post-operatively the patient experienced the first of several acute knee dislocations. Closed reduction was performed at an outside hospital a total of three

MOBILE and the provision of total joint replacement [PDF]
, 2008 Modern joint replacements have been available for 45 years, but we still do not have clear indications for these interventions, and we do not know how to optimize the outcome for patients who agree to have them done.

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.Abstract Purpose The posterior cruciate‐retaining (CR) design offers rotational freedom but risks abnormal kinematics and instability. The medial pivot (MP) design mimics native joint motion with a high‐conformity medial and flat lateral interface. Within clinical studies, the MP design outclassed the CR design, but biomechanical studies are lacking ...
