BACKGROUND The purpose of this investigation was to evaluate if clinical assessment, Ultrasound + Colour Doppler (US + CD) and Ultrasound Tissue Characterisation (UTC) can be useful in detecting plantaris tendon involvement in patients with midportion Achilles tendinopathy. METHODS Twenty-three tendons in 18 patients (14 men, mean age: 37 years and 4 women: 44 years) (5 patients with bilatera...

BACKGROUND Semitendinosus and gracilis muscles whose tendons are used in surgical reconstruction of the anterior cruciate ligament maintain their contractile ability, and a limited decrease of hamstring muscles force is observed postoperatively despite important changes. The goal was to quantify the influence of the myofascial structures on excursions and moment arms of knee muscles to attempt ...

Hamstring muscle injuries are common in athletes and mostly consist of sprains at the myotendinous junction, which often respond well to conservative treatment. Proximal hamstring avulsion injuries, though less common, can be severely debilitating. This injury is often seen in water skiers but has been described in many other sports and in middle-aged patients. Complete avulsions in young and a...

This study examined the effectiveness of a functional hamstring training exercise, the razor curl on conditioning the hamstring and gluteal musculature. Eight healthy, female intercollegiate athletes participated (mean age 20.8 +/- 3.9 years; mean height, 177.8 +/- 10.9 cm; mean weight, 67.3 +/- 9.9 kg). Electromyographic (EMG) data were collected on the following muscles: medial hamstring (sem...

Background: Hamstring muscle injuries are among the most common lower extremity injuries in athletes. Pain in the posterior thigh and leg weakness are usual presenting symptoms. Less dramatic onset in nonathletes, without pain in the posterior thigh, is more often thought of as an ischial bursitis or as pain from the sacroiliac joint or the gluteal or piriformis muscles. Pain localized over the...

Recent anatomical and biomechanical studies on the anterolateral ligament (ALL) of the knee have shown that this structure has an important function in relation to joint stability, especially when associated with anterior cruciate ligament (ACL) injury. However, the criteria for its reconstruction have not yet been fully established and the surgical techniques that have been described present v...

In order to reconstruct the medial knee to restore the original biomechanical function of its ligamentous structures, a thorough understanding of its anatomic placement and relationship with surrounding structures is required. To restore the knee to normal kinematics, the diagnosis and surgical approach have to be aligned, to successfully reconstruct the area of injury. Three important ligament...
