It is a well-known fact that the verisimilitude of sustaining the anterior cruciate ligament (ACL) injury in a noncontact situation is greater for females than for males, dramatically (1). In sports science, many researchers have studied the mechanism and the risk factors of ACL injury, and excessive knee valgus angle (KVA) has received considerable attention as a reason of higher incidence of ...

Female athletes are substantially more susceptible than males to suffer acute non-contact anterior cruciate ligament injury. A limited number of studies have identified possible biomechanical risk factors that differ between genders. The effect of fatigue on the biomechanics of landing has also been inadequately investigated. The objective of the study was to examine the effect of gender and fa...

BACKGROUND Accurate femoral rotational alignment is of vital importance for successful total knee arthroplasty (TKA). The value of computer-assisted surgery TKA (CAS-TKA) in increasing the accuracy of femoral rotational alignment remains controversial. We hypothesize that outcomes are related to the severity of preoperative varus and valgus deformity and that CAS-TKA may be beneficial under cer...

PURPOSE Since the existence of an extra-articular deformity seriously alters the normal geometry and kinetics around the knee joint, difficulties are often encountered in total knee arthroplasty (TKA) using a standard surgical technique. The purpose of this study was to evaluate the usefulness of surgical navigation system as a treatment option for osteoarthritic knees with extra-articular defo...

OBJECTIVE Excessive frontal plane knee movement during forward lunge movements might be associated with the occurrence of knee injuries in tennis. Here, we attempt to determine whether hip muscle strength is related to the frontal plane motion of the knee during a functional lunge movement. DESIGN A correlational study. PARTICIPANTS A total of 84 healthy subjects (76 men, 8 women), with no ...

ACL injuries are multifactorial in nature meaning they can be the result of faulty biomechanics, individual genetic predisposition, or environmental factors (Alentorn- Geli et al., 2009). A focus most healthcare professionals including physical therapists and athletic trainers includes screening for preventable risk non- contact injuries. Preventable include asymmetry between a person’s limbs, ...

The objectives of this study were (1) to develop subject-specific experimental and finite element (FE) techniques to study the three-dimensional stress-strain behavior of ligaments, with application to the human medial collateral ligament (MCL), and (2) to determine the importance of subject-specific material properties and initial (in situ) strain distribution for prediction of the strain dist...

BACKGROUND There are many opinions and controversies regard the effect of lateral wedge insoles and valgus stress 3point knee braces in treatment of medial compartment knee osteoarthritis (OA). In this study we compared the effect of lateral wedge insoles and 3 point knee supports in treatment of medial compartment knee OA. METHOD Sixty patients (35-65 years), with knee pain and genu varum an...
