OBJECTIVE
Reports in the literature of low-energy (LE) knee dislocation (KD) in obese patients have been increasing. This study was undertaken to define the risk factors for KD by LE mechanisms and the outcomes of these patients compared with those with high-energy (HE) trauma.
METHODS
All patients
Knee dislocations are rare injuries typically associated with severe traumatic mechanisms. We report 2 cases of morbidly obese patients who had complete knee dislocations after falls from standing height. Both cases resulted in significant morbidity secondary to popliteal artery injury. Emergency
Knee dislocations of morbidly obese patients after a trivial fall are not uncommon. We report a case of closed reduction for a dislocated right knee of a 26-year-old obese woman. After closed reduction under general anaesthesia, her knee was supported by pillows in 30 degrees flexion. No external
Complete dislocation of the knee joint is a severe injury that is commonly the result of high-velocity injuries and often associated with disruption of the popliteal artery. We report two cases in which obesity appeared to be the principal cause of knee dislocation with vascular compromise.
OBJECTIVE
The purpose of this study was to evaluate the incidence, cause, injury patterns, and MRI findings in knee dislocation in patients with normal and increased body mass index and to determine whether obesity interferes with knee MRI examinations.
METHODS
A retrospective study of the period
We describe a case of a morbidly obese Jehovah's Witness who sustained a popliteal artery and vein transection after a spontaneous knee dislocation. Following surgical repair, the patient fatally deteriorated, while blood products had to be withheld according to the patient's preoperative request.
Though a relatively rare orthopedic injury, knee dislocation in the morbidly obese population has been increasingly reported in the literature. These injuries are often referred to as "ultralow-velocity knee dislocations" since they commonly occur after a seemingly trivial injury, such as a ground
BACKGROUND
Knee dislocations from minor trauma have been reported sparsely in the literature. The consensus is that these injuries tend not to be associated with neurovascular compromise.
OBJECTIVE
To present a series of atraumatic knee dislocations in obese and morbidly obese patients and to
Ultra-low-velocity knee dislocations are historically rare but increasingly common events. They occur most frequently in obese, morbidly obese, and super obese patients during everyday activities, but they can be as severe or more severe than high-velocity knee dislocations. Ultra-low-velocity knee
OBJECTIVE
With rising rates of obesity in the United States, the burden of knee dislocations in this population remains unknown. This national epidemiologic study was designed to analyze the association of obesity with closed knee dislocation and vascular complications.
METHODS
Retrospective cohort
Avulsion fractures of the intercondylar eminence or tibial spine mostly occur in children and adolescents, and are extremely uncommon in adults. A type IIIB intercondylar eminence fracture (i.e. completely displaced and rotated tibial spine) associated with a complex knee dislocation is an extremely
Traumatic knee dislocation is a serious and potentially limb threatening injury that can be easily missed if meticulous history and examination have not been employed. Neurovascular injuries are common in this condition, and due diligence should be given to their thorough evaluation at time of
Complete knee dislocation is a rare and severe injury and usually follows high-energy trauma. Non-traumatic knee dislocations are exceedingly rare, while severe overweight appears to be the main cause of the knee dislocation. We here report on a spontaneous knee dislocation in a patient with severe
OBJECTIVE
Morbidly obese patients who sustained popliteal vascular injury after spontaneous knee dislocation (KD) were studied.
METHODS
Seven morbidly obese patients (body mass index [BMI] >35 kg/m2 and >100 lb over ideal body weight) who sustained spontaneous KD while upright were
