There is considerable evidence to support a number of biomechanical risk factors associated with non-contact anterior cruciate ligament (ACL) injury. This paper aims to review these biomechanical risk factors and highlight future directions relating to them. Current perspectives investigating trunk position and relationships between strength, muscle activity and biomechanics during landing/cutt...

BACKGROUND Hamstring injuries are the most common muscle injuries in soccer, and they have a high rate of recurrence. Eccentric hamstrings strength is recognized as an important modifiable risk factor. This led to the development of prevention exercises such as the nordic hamstring exercise (NHE). The effectiveness of the NHE on hamstring injury prevention has never been investigated in amateur...

BACKGROUND Because a proximal hamstring avulsion results in residual loss of function, surgical repair is recommended. Few studies have investigated postoperative function with validated outcomes. PURPOSE To examine lower extremity function after surgical repair of proximal hamstring avulsions using validated self-reported and performance-based functional outcomes. STUDY DESIGN Case series;...

CONTEXT Hamstring acute muscle injuries are prevalent in several sports including AFL football (Australian Football League), sprinting and soccer, and are often associated with prolonged time away from sport. EVIDENCE ACQUISITION In response to this, research into prevention and management of hamstring injury has increased, but epidemiological data shows no decline in injury and re-injury rat...

The aim of the study was to analyse the effect of mulligan bent leg raise technique on hamstring trigger point. 40 subjects who were diagnosed by hamstring trigger point randomly recruited in the study All subjects received Mulligan bent leg raise technique (BLR), To determine the effect of intervention the patient were assessed on the measures of Active knee extension test (AKE) and visual ana...

The purpose of this study was to evaluate the results of operative treatment of entrapment of the sciatic nerve by tight fibrous structures associated with the hamstring tendons close to their proximal insertion. We retrospectively evaluated the results of 22 operations performed in 16 patients (6 bilateral operations), on average six years postoperatively. There was complete relief in 11 cases...

Br J Sports Med February 2012 Vol 46 No 2 81 Acute hamstring injuries are the most prevalent muscle injuries reported in sport. Despite a thorough and concentrated effort to prevent and rehabilitate hamstring injuries, injury occurrence and re-injury rates have not improved over the last three decades. This failure is most likely due to the following: (1) a lack of studies with high level of ev...

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...

PURPOSE The aim of the present study was to compare primary stability in ACL reconstruction and ultimate load to failure of a mesh augmented hamstring tendon graft fixed with two cross pins to established hamstrings and bone-patellar-tendon-bone (BTB) graft fixation methods. METHODS Forty fresh porcine femora were divided into four groups: (A): BTB graft fixed with two RigidFix® pins, (B): ha...

BACKGROUND Despite the importance of hamstring tendon autograft, one major disadvantage in applying this technique in the surgical reconstruction of anterior cruciate ligament is individual variability in the tendon diameter. Hence, the purpose of the present study was to use anthropometric parameters such as gender, height and body mass index to predict 4-strand (quadruple) hamstring tendons (...
