Small knee flexion angles at initial contact and large ground reaction forces during landing have been identified as risk factors for non-contact anterior cruciate ligament injuries that are common in sports. This study investigated the effects of knee extension constraint on knee flexion angle and ground reaction forces for patients who were 4-6 months post ACL reconstruction surgery, and also...

OBJECTIVE To determine changes in physical and social function during a prolonged preoperative waiting period and at 3 months after total knee arthroplasty. SUBJECTS Forty-three patients were evaluated on the day that surgery was decided, the day before surgery, and 3 months afterwards. METHODS Knee pain and function were assessed using a visual analogue scale and a functional assessment sy...

BACKGROUND Gap-balancing is an alignment method for total knee arthroplasty with the goal of creating uniform tension in the periarticular soft-tissue restraints and equal laxities throughout the arc of flexion. However, there is little evidence that achieving equal laxities prevents either overly tight or overly loose soft-tissue restraints after total knee arthroplasty. Accordingly, the purpo...

BACKGROUND Little information exists to support that patients care about flexion beyond what is needed to perform activities of daily living (ADL) after Total knee arthroplasty (TKA). The purpose of this study was to investigate if the achievement of a higher degree of knee flexion after TKA would result in a better patient perceived outcome. METHODS The study is a randomized, double-blinded,...

The hamstrings are often associated with the development of crouch gait, a fatiguing form of walking characterized by excessive hip flexion, knee flexion and ankle dorsiflexion during stance. However, recent studies have called into question whether abnormally active hamstrings induce the limb to move into a crouch posture. The purpose of this study was to directly measure the influence of the ...

PURPOSE Because a strong and stable knee is paramount to an athlete's or patient's success, an understanding of knee biomechanics while performing the squat is helpful to therapists, trainers, sports medicine physicians, researchers, coaches, and athletes who are interested in closed kinetic chain exercises, knee rehabilitation, and training for sport. The purpose of this review was to examine ...

Knee OA is the most common degenerative disease in old individuals which affects ability of walking, sitting and climbing stairs. There are several manual therapy techniques for limited painful knee flexion, but there very few evidence about combined effect Exercise Mulligan’s Mobilization with Movement (MWM) osteoarthritis knee.

BACKGROUND The cruciate ligaments are important stabilizers of the knee joint and determine joint kinematics in the natural knee and after cruciate retaining arthroplasty.No in vitro data is available to biomechanically evaluate the ability of the anterior cruciate ligament (ACL) to maintain knee joint kinematics after bicruciate-retaining bi-compartmental knee arthroplasty (BKA).Therefore, the...

Knee joint pain is a common symptom in obese individuals and walking is often prescribed as part of management programs. Past studies in obese individuals have focused on standing alignment and kinematics in the sagittal and coronal planes. Investigation of 6 degree-of-freedom (6DOF) knee joint kinematics during standing and gait is important to thoroughly understand knee function in obese indi...
