iNew Medicine, EarlyView.In the freezing of gait in Parkinson's disease, white matter shows decreased local activity but increased functional connectivity. These distinct dysfunctions are uniquely associated with specific neurotransmitter systems (GABA, dopamine, etc.), mapping a new neurochemical basis for this debilitating symptom. ABSTRACT Freezing of gait (FOG) is a severe

Journal of Orthopaedic Research, EarlyView.ABSTRACT Total knee replacement (TKR) is a successful intervention for relieving pain and improving quality of life. In this context, mid‐flexion instability and paradoxical anterior femoral movement remain challenging. However, the role of implant design in cruciate‐sacrificing (CS) scenarios is unclear.

Personalized alignment in total knee arthroplasty reduces patellar tilt: A retrospective study
Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.Abstract Purpose Patellofemoral kinematics is crucial for patient satisfaction following total knee arthroplasty (TKA). A postoperative patellar tilt greater than 5° has been associated with inferior clinical outcomes. While a femoral component external rotation beyond 3° is generally protective against patellar tilt, personalized alignment may not ...
