 Quadriceps Tendonitis Information & Treatment Advice - iTendonitis.com
Quadriceps tendonitis is the inflammation and irritation of the quadriceps tendon.
Quadriceps tendonitis is a very common condition amoungst athletes and sports peoplewho are involved in activites that place excess strain and the knees and legs.
Quadriceps tendonitis usually occurs as a result of overdoing an activity and placing too much stress on the quadriceps tendon before it is strong enough to handle the stress.

 eMedicine - Quadriceps Injury : Article by Thomas M DeBerardino
Rupture of the quadriceps tendon after surgery may be associated with the procedure to harvest the graft used to reconstruct the cruciate ligaments or aggressive release of soft tissues in the case of lateral release and total knee replacement.
Muscle strain: Tenderness is elicited by direct palpation of the quadriceps at the patellar insertion, or the patient reports pain when testing for resisted extension.
Quadriceps muscle hernia: A soft mobile mass, which may be tender, is palpated anteriorly with contraction of the quadriceps.

 Spartanburg SC | GoUpstate.com | Spartanburg Herald-Journal
The quadriceps femoris (quadriceps, quadriceps extensor, guads or quads) includes the four prevailing muscles on the front of the thigh.
It is the great extensor muscle of the knee, forming a large fleshy mass which covers the front and sides of the femur.
All four parts of the quadriceps muscle attach to the patella via the quadriceps tendon.

 The function of the quadriceps muscle after a fracture of the femur in - Wheeless' Textbook of Orthopaedics
Six patients (18 per cent) had a deficit according to the one-leg-hop for distance test, fourteen (42 per cent) had an average loss of ten millimeters in the circumference of the thigh, and sixteen (48 per cent) had an average loss of 10 degrees of flexion of the knee.
The amount of maximum displacement of the fracture, as seen on the initial radiographs, was the only factor that was significant for the prediction of weakness of the quadriceps (p = 0.006) at both test speeds of the Cybex dynamometer and in all statistical analyses.
A subclinical deficit in the strength of the quadriceps may be related to damage sustained by the muscle at the time of the fracture.

 Muscle-relaxers.org - Muscle Systems
Back pain is one of the most common forms of muscle pain and may come as the result of an injury or as a side effect of another condition.
In the case of muscle spasms, a muscle relaxant may be prescribed for a short time, or three to four days.
Muscle relaxants are also sometimes used to treat Fibromyalgia, a condition that involves aches, stiffness and tiredness.

  QUADRICEPS TENDON RUPTURE AND SURGICAL REPAIR
The quadriceps muscle is the large muscle on the front of the thigh.
As the quadriceps muscle contracts (shortens), it pulls on the quadriceps tendon, the patella, the patellar tendon, and the tibia to move the knee from a flexed (bent) position to an extended (straight) position.
The examination consists of palpating the quadriceps tendon and the patella.

 Knee function reduced following surgery due to decreased quadriceps strength
The results showed that muscle strength and functional performance were lower for the leg that was operated on compared to the leg that was not operated on.
They add that the relationship between the quadriceps strength ratio and the 1-leg rising test ratio (in which the seated patient was asked to rise on one leg as many times as possible in succession) may indicate that decreased quads strength contributes to limited knee function.
Muscle impairment may also contribute to the feeling of instability that meniscectomy patients frequently mention and may play a role in osteoarthritis.

 Building Bigger Stronger Thigh Muscles: Quadriceps
The quadriceps are powerful muscles and when the quadriceps incorporate the equally powerful gluteals, very heavy loads can be placed on the entire body.
The VMO is the primary muscle in the quadriceps for full-knee extension and knee stability.
Bodybuilders use this high-risk exercise to move the stress load from the gluteals and hips to the quadriceps and primarily the vastus lateralis in the quadriceps group.

 Muscle Performance References
Quadriceps endurance decreased, whereas the effect of superimposing single twitches on isometric contraction and hand-grip strength was unaffected by the GH treatment.
Muscle strength and muscle fatigue were estimated by measuring torques in the ankle during attempts of maximal voluntary contraction (MVC) in the direction of dorsal flexion of the foot and during electrically evoked contractions (EEC).
Muscle strength was estimated by measuring torques in the ankle during short attempts of maximal voluntary isometric contraction (MVIC) in the direction of dorsal flexion of the foot.
