STUDY DESIGN Phenomenographic, cross-sectional. OBJECTIVES To describe ways of experiencing participation in activities of individuals with a nonreconstructed anterior cruciate ligament injury and to describe the emotional aspects related to participation. Further, the objective was to explore factors affecting the activity level. BACKGROUND The importance of assessing different factors (kn...

BACKGROUND Identification of biomechanical risk factors associated with anterior cruciate ligament (ACL) injury can facilitate injury prevention. The purpose of this study is to investigate the effects of three foot landing positions, "toe-in", "toe-out" and "neutral", on biomechanical risk factors for ACL injury in males and females. The authors hypothesize that 1) relative to neutral, the toe...

Internal tibial rotation with the knee close to full extension combined with valgus collapse during drop landing generally results in non-contact anterior cruciate ligament (ACL) injury. The purpose of this study was to investigate the relationship between internal rotation of the knee and muscle activity from internal and external rotator muscles, and between the internal rotation of knee and ...

One of the most frequent issues humans have had to deal with from beginning time is a knee injury. Knee injuries caused by variety diseases, acute degenerative, can affect articular cartilage. The trauma, infection, or inflammation this In these circumstances, full clinical examination not possible since patients are in too much pain cooperate. Then non-invasive multiplanar imaging and MRI come...

Post-traumatic osteoarthritis (PTOA) is a common long-term consequence of joint injuries such as anterior cruciate ligament (ACL) rupture. In this study we used a tibial compression overload mouse model to compare knee injury induced at low speed (1mm/s), which creates an avulsion fracture, to injury induced at high speed (500mm/s), which induces midsubstance tear of the ACL. Mice were sacrific...

BACKGROUND High knee abduction moment (KAM) landing mechanics, measured in the biomechanics laboratory, can successfully identify female athletes at increased risk for anterior cruciate ligament (ACL) injury. METHODS The authors validated a simpler, clinic-based ACL injury prediction algorithm to identify female athletes with high KAM measures. The validated ACL injury prediction algorithm em...

This research aimed to determine when kinetic changes place greatest risk for noncontact ACL (anterior cruciate ligament) injury during football cutting in match play. Fourteen professional football players undertook three trials of a straight line run and sidestep cutting at 30° and 60° with standardised velocity on an approved football surface. Two types of standardised studded football boots...

BACKGROUND Knee valgus load during sports movement is viewed as an important predictor of non-contact anterior cruciate ligament injury risk, particularly in females. Formulating movement strategies that can reduce valgus loading during these movements therefore appears pertinent to reducing anterior cruciate ligament injury rates. With this in mind, the current study examined the relationship ...
