Effects of the ankle angle on the electromyographic activity of the trunk and lower extremities during isometric squat exercises

Journal of Men's Health, 2022
Background: Life in modern society has become convenient, but the lack of exercise due to a sedentary lifestyle has led to muscle weakness. The quadriceps femoris is essential for walking, standing, and using stairs in daily life.

Allograft Medial Patellofemoral Ligament Reconstruction Using Patellar Suture Anchors and Stepwise Medial Imbrication. [PDF]

Arthrosc Tech
Abstract Patellar instability commonly affects adolescents and young athletes and is associated with injury to the medial patellofemoral ligament (MPFL). MPFL reconstruction is a well‐established treatment for recurrent instability; however, complications related to graft tensioning, fixation, and incomplete restoration of medial soft‐tissue restraints

Comprehensive Medial Knee Four-Arm Reconstruction to Address Complex Instability With Hamstring Autograft. [PDF]

Arthrosc Tech
Abstract Medial knee ligament injuries are increasingly recognized as complex, multiplanar lesions, resulting not only in simple medial instability but also anteromedial rotatory instability, anteromedial instability, posteromedial instability, posteromedial rotatory instability, and post‐traumatic medial asymmetric hyperextension.

A cadaver study of the function of the oblique part of vastus medialis [PDF]

The Journal of Bone and Joint Surgery. British volume, 1995
Six normal cadaver lower limbs were mounted on a specially designed loading apparatus. Wires were used to simulate the five muscle bellies of the quadriceps, the ratio of their tensions having been determined from that of the anatomical cross-sectional areas of the muscles. A three-camera system was used to track the patella during knee movements from

The Effect of Patellofemoral Pain Syndrome in Athletes on Electromyographic Activity Ratio of Patellar Stability Muscles during Maximum Voluntary Isometric Contraction [PDF]

Sport Sciences and Health Research, 2013
Patellofemoral pain syndrome is a common condition athletes suffer from. One of the predictive factors of this syndrome is reduced activity ratio of vastus medialis oblique (VMO) to vastus lateralis (VL).
