Context: Quadriceps and hamstrings weakness occurs frequently after anterior cruciate
ligament (ACL) injury and reconstruction. Evidence suggests that knee injury may precipitate …

Background: After an anterior cruciate ligament (ACL) injury, the uninjured contralateral
lower limb may become weakened because of neuromuscular changes, proprioceptive …

Objective Even some time after a ruptured ACL has been reconstructed thigh musculature
atrophy, voluntary activation, and knee-extensor strength deficits may be encountered. The …

Objectives Quadriceps weakness persists after anterior cruciate ligament reconstruction.
Muscle atrophy and activation failure may contribute. This study examined the roles of …

Objective: To determine the association of quadriceps and hamstrings strength to anterior
cruciate ligament (ACL) injury risk in female athletes. The primary hypothesis was that there …

Context: Individuals with anterior cruciate ligament reconstruction (ACLR) have quadriceps
dysfunction that contributes to physical disability and posttraumatic knee osteoarthritis …

Objective: To identify preoperative predictive factors for knee function two years after
reconstructive surgery of the anterior cruciate ligament (ACL). The main hypothesis was that …

Study Design Cross-sectional analytical study in which subjects served as their own
controls. Objective To assess the concentric and eccentric peak toque in the hamstrings and …

Background: Core stability is influential in the incidence of lower extremity injuries, including
anterior cruciate ligament (ACL) injuries, but the effects of core strength training on the risk …

We evaluated whether quadriceps and hamstrings weakness depended on chronicity in
amateur athletes with anterior cruciate ligament deficiencies. We hypothesized that the …
