Anatomical variations in vastus medialis obliquus and its implications in minimally-invasive total knee replacement. An MRI study.

Effect Of Vastus Medialis Obliquus Deficiency On Patellar Bone Strain After Total Knee Arthroplasty

Anatomy of the lateral retinaculum of the knee.

Anatomical descriptions of the lateral retinaculum have been published, but the attachments, name or even existence of its tissue bands and layers are ill-defined. We have examined 35 specimens of the knee. The deep fascia is the most superficial layer and the joint capsule is the deepest. The intermediate layer is the most substantial and consists of derivatives of the iliotibial band and the ...

The Immediate Effect of Knee Brace on the Activity of Selected Lower Limb Muscles during Stance Phase of Walking in Females with Patellofemoral Pain Syndrome

Background & Aims: The purpose of this study was to determine the immediate effect of patella support brace on co-contraction and electromyographic activity of selected lower limb muscles in females with patellofemoral pain syndrome during stance phase of gait. Methods: EMG activity of vastus lateralis, vastus medialis, rectus femoris, gastrocnemius, biceps femoris, semitendinosus, gluteus medi...

Vastus Lateralis and Vastus Medialis Obliquus Activity During a Straight-Leg Raise and Knee Extension With Lateral Hip Rotation

Objective: To compare average electromyogram (EMG) activity of the vastus medialis obliquus (VMO) and vastus lateralis (VL) during straight-leg raise (SLR) and knee extension (KE) with the hip in neutral and lateral rotation. Design: 1  4 factorial repeated-measures. Setting: Laboratory. Participants: 13 male college students. Intervention: SLR with hip flexed at 40°, in neutral position, and ...

A Biomechanical Study in Vitro

J Bone Joint Surg [Br] 2005;87-B:577-82. Received 8 July 2003; Accepted after revision 18 June 2004 Normal function of the patellofemoral joint is maintained by a complex interaction between soft tissues and articular surfaces. No quantitative data have been found on the relative contributions of these structures to patellar stability. Eight knees were studied using a materials testing machine ...
