quadriceps and hamstrings muscles represent the primary dynamic stabilizers of the knee joint. Anterior shear force generated during knee extension, as well as the contact phase of landing, is mainly determined by the quadriceps muscle action via the patella tendon-tibia shaft angle. 24 , 25 During landing

bone patellar tendon bone (BTB) and hamstring tendon (HT) grafts, especially skeletally mature patients with ACL. For skeletally immature ACL patients with significant growth remaining, physeal-sparing techniques are often utilized. The most well-studied physeal-sparing technique to date is the

The triceps surae muscle–tendon units are important in governing walking performance, acting to regulate mechanical behavior of the ankle joint through the interaction between active muscle and passive elastic structures. 1 – 3 Ankle joint quasi-stiffness (k A ), the slope of the relation between

The present case describes the conservative treatment of a supraspinatus tendon tear with accompanying scapular dyskinesis in a synchronized ice skater. While rotator cuff injuries are present in ice skating, 20 , 21 to the author’s knowledge, this is the first case study detailing a successful

return to sport (RTS). 4 , 5 Traditionally, a bone–patellar tendon–bone (BPTB) graft has been the preferred method of ACLR, 6 though systematic reviews over the past 10–15 years have demonstrated the lack of superiority of BPTB over hamstring autografts, 7 with less postoperative complications

return to preinjury performance and functional level of professional athletes or injured individuals. 8 ACLR can be performed using a hamstring or patellar tendon autograft. In surgical techniques using hamstring tendon grafts, anterior knee pain, loss of proprioception, decrease of hamstring muscle
