A 5-year follow-up of Achilles tendon reconstruction using a full-thickness graft processed with the clearant method and retrograde fixation in the calcaneus: a case study of an amateur soccer player
We present a case of a 41-year-old male amateur soccer player with no comorbidities, who experienced a rerupture of the Achilles tendon 5 years after his initial end-to-end plasty. To address this, we opted fo... (Source: Journal of Experimental Orthopaedics)

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
In total knee arthroplasty (TKA) with posterior cruciate ligament (PCL) retention, the medial and lateral insert conformity that restores in vivo native (i.e., healthy) knee tibial rotation and high function w... (Source: Journal of Experimental Orthopaedics)

Unrestricted kinematic alignment corrects fixed flexion contracture in robotically aligned total knees without raising the joint line in extension
Mechanically Aligned Total Knee Arthroplasty (MA TKA) typically addresses fixed flexion contractures (FFC) by raising the joint line during extension. However, in unrestricted Kinematically Aligned TKA (KA TKA... (Source: Journal of Experimental Orthopaedics)

Distal Kaplan fibers and anterolateral ligament injuries are associated with greater intra-articular internal tibial rotation in ACL-deficient knees based on magnetic resonance imaging
The purpose of the present study was to assess the internal rotation of the tibia on Magnetic Resonance Imaging (MRI) in a series of consecutive athletes with Anterior cruciate Ligament (ACL) tears. (Source: Journal of Experimental Orthopaedics)
