Quadricepsplasty for Patellar Obligate (Habitual) Lateral Flexion Dislocation [PDF]

Arthroscopy Techniques
There are multiple underlying etiologies of patellar instability including both osseous and soft-tissue factors. Obligate flexion dislocation consists of lateral dislocation of the patella, occurring each time the knee flexes. This generally results from

Medial patellofemoral ligament is a part of the vastus medialis obliquus and vastus intermedius aponeuroses attaching to the medial epicondyle. [PDF]

Knee Surg Sports Traumatol Arthrosc, 2022
AbstractPurposeThis study aimed to investigate the bony surface characteristic of the femoral attachment of the medial patellofemoral ligament (MPFL) and the correlation between the relevant layered structures, including muscular aponeurosis and the joint capsule, which contribute to patellofemoral joint (PFJ) stability.MethodsThe morphology of the ...

Vastus medialis obliquus muscle morphology in primary and recurrent lateral patellar instability. [PDF]

Biomed Res Int, 2014
The morphology of the vastus medialis obliquus (VMO) muscle in the anatomical setting of an unstable patella has not been described. Therefore, the purpose of this study was to investigate the morphological parameters of the VMO muscle that delineate its importance in the maintenance of patellofemoral joint stability.

Computational assessment of the influence of vastus medialis obliquus function on patellofemoral pressures: Model evaluation [PDF]

Journal of Biomechanics, 2010
A study was performed to evaluate a computational model used to characterize the influence of vastus medialis obliquus (VMO) function on the patellofemoral pressure distribution. Ten knees were tested in vitro at 40 degrees, 60 degrees and 80 degrees of knee flexion with quadriceps loads applied to represent a normal VMO, and with the VMO force ...

Tendon Yaw (TY) Angle: Direct Measurement of the Quadriceps Vector Resolves the Rotational Enigma of Recurrent Patellar Instability [PDF]

Medicina
Background and Objectives: To validate a computed tomography (CT) measure of tendon yaw (TY) and determine its diagnostic specificity, precision, and clinical relevance in recurrent patellar instability (RPI) in comparison with standard imaging tests ...

Improving vastus medialis obliquus function reduces pressure applied to lateral patellofemoral cartilage [PDF]

Journal of Orthopaedic Research, 2009
AbstractThe current study was performed to characterize how improving vastus medialis obliquus (VMO) function influences the pressure applied to patellofemoral cartilage. An additional focus was characterizing how lateral and medial cartilage lesions influence cartilage pressures.

Delayed onset of electromyographic activity of vastus medialis obliquus relative to vastus lateralis in subjects with patellofemoral pain syndrome

Gait and Posture, 2010
Patellofemoral Pain Syndrome (PFPS) is a common musculoskeletal complaint. The presence of a delay between vastus medialis obliquus (VMO) and vastus lateralis (VL) muscle onset has been suggested in the literature as a possible cause of PFPS, with poor agreement amongst authors on the value of the delay.

Evaluation of the reduction in perceived and performance fatigability by functional compression tights during squat exercises via electromyography and electroencephalography analysis. [PDF]

PLoS ONE
ObjectivesFunctional compression tights are widely used to support muscle activity, enhance blood flow and reduce fatigue, which comprises performance (motor or cognitive) and perceived fatigability.
