BACKGROUND To identify and characterize the concomitant ligamentous and meniscal injuries in floating knee. METHODS A total of 37 cases of floating knee were enrolled. Arthroscopic or open surgical examination of the knee, Lachman test, posterior drawer's test, and varus and valgus stress tests under anesthesia were carried out to determine the incidence of knee injury. RESULTS Through arth...

BACKGROUND Self-reported knee joint instability compromises function in individuals with medial knee osteoarthritis and may be related to impaired joint mechanics. The purpose of this study was to evaluate the relationship between self-reported instability and the passive varus-valgus mechanical behaviour of the medial osteoarthritis knee. METHODS Passive varus-valgus angular laxity and stiff...

BACKGROUND There is a lack of knowledge on the primary and secondary static stabilizing functions of the posterior oblique ligament (POL), the proximal and distal divisions of the superficial medial collateral ligament (sMCL), and the meniscofemoral and meniscotibial portions of the deep medial collateral ligament (MCL). HYPOTHESIS Identification of the primary and secondary stabilizing funct...

objectives: knee osteoarthritis (oa) is a leading cause of disability in older adults. in current study, the effects of three types of orthoses on pain reduction were evaluated in oa patients in iran. methods & materials: in this prospective clinical trial, thirty six patients consisting of 11 men and 25 women with age (mean±sd) of 54.56±2.82 years and diagnosis of mild to moderate knee oa incl...

OBJECTIVE To evaluate whether an alteration of the lower limb axis is associated with meniscal extrusion. MATERIALS AND METHODS Ninety-four patients who had complained of knee pain with good knee function and had a knee magnetic resonance image (MRI) and a full-length X-ray taken of the lower limb were included in the study. Meniscal extrusion was measured in the coronal MRI. Subluxation of t...

BACKGROUND The mechanisms of anterior cruciate ligament injury in basketball are not well defined. PURPOSE To describe the mechanisms of anterior cruciate ligament injury in basketball based on videos of injury situations. STUDY DESIGN Case series; Level of evidence, 4. METHODS Six international experts performed visual inspection analyses of 39 videos (17 male and 22 female players) of a...

CONTEXT Multiple factors have been suggested to increase the risk of faulty dynamic alignments that predict noncontact anterior cruciate ligament injury. Few researchers have examined this relationship using an integrated, multifactorial approach. OBJECTIVE To describe the relationship among static lower extremity alignment (LEA), hip muscle activation, and hip and knee motion during a single...

The ligaments of the knee consist of fiber bundles with variable orientations, lengths and mechanical properties. In concept, however, these structures were too often seen as homogeneous structures, which are either stretched or slack during knee motions. In previous studies, we proposed a new structural concept of the ligaments of the knee. In this concept, the ligaments were considered as mul...

The internal brace technique uses a high-strength suture tie to augment injured tissues or a primary repair, allowing early rehabilitation. Anatomic repair with internal bracing is a novel and promising treatment for femoral-sided medial knee avulsion injuries of the medial collateral ligament and posterior oblique ligament. Unfortunately, biomechanical and clinical data are lacking. To evaluat...

CONTEXT Patellofemoral pain syndrome (PFPS) is one of the most common overuse injuries. OBJECTIVE To assess the collective evidence of predisposing factors to PFPS. DATA SOURCES MEDLINE (1960-June 2010), EMBASE (1980-June 2010), and CINAHL (1982-June 2010). STUDY SELECTION Studies were included if patients were asymptomatic at baseline testing (free of PFPS) and were prospectively followe...
