This study investigated the effects of seat-height settings of wheelchairs with alternating propulsion with both legs. Seven healthy individuals with no orthopedic disease participated. Flexion angles at initial contact (FA-IC) of each joint, range of motion during propulsion period (ROM-PP), and ground reaction force (GRF) were measured using a three dimensional motion capture system and force...

MacIntosh metallic tibial plateau prostheses have been used in the Nuffield Orthopaedic Centre since 1966 in the knees of patients with rheumatoid arthritis, following the description of the use of these prostheses for the relief of pain and the correction of deformity by MacIntosh (1966). Since that time thfre have been several reports of the use of these prostheses in both rheumatoid and oste...

Knee dislocation after revision total knee arthroplasty (TKA) is a dangerous, albeit rare, injury that can lead to neurovascular compromise and permanent disability. A paucity of peer-reviewed literature exists regarding this complication after revision TKA. Tibiofemoral dislocation commonly occurs with minimal trauma, such as rising from a seated position, and is commonly associated with a fle...

Introduction Congenital syphilis is still a public health issue worldwide. Beyond the neonatal period, clinical findings may be subtle and nonspecific. We report an unusual case of congenital syphilis with recurrent fever, knee pain and severe anemia in a 28 month-old boy, despite standard penicillin treatment early in life. Congenital syphilis should be considered throughout early childhood, e...

Two cases of dislocation of total knee arthroplasty presented to us within the same week. The first patient is a 71-year-old woman who underwent bilateral primary total knee arthroplasty. The left knee dislocated three weeks after the surgery. Due to failure of conservative measures, she underwent revision total knee arthroplasty. The other patient is a 72-year-old woman presenting ten years af...

Traumatic knee dislocation is a complex ligamentous injury that may be associated with simultaneous vascular and neurological injury.Although orthopaedic surgeons may consider CPN exploration at the time of ligament reconstruction, there is no standardised approach to the management of this complex and debilitating complication.This review focusses on published evidence of the outcomes of commo...

Complete dislocation of the knee is a relatively rare condition. When it occurs as a result of high-velocity injury, such as in a road traffic accident, associated vascular injury is generally suspected. In low-velocity injuries, however, distal pulses are often maintained throughout, and the possibility of vascular injury may erroneously be discounted. We report four cases of low-velocity disl...

multiplanar or global laxity in arthritic knee is rare , most of this patients have neuromuscular disorder (post poliomyelitis , spinal dystrophy) or history of knee trauma. ligament insufficiency and severe bone loss is significant in this patient. the estimated prevalence for the concurrence of charcot marie-tooth (cmt) with myasthenia gravis (mg) suggests an extremely rare event. we have pre...

Knee dislocations are uncommon as isolated orthopaedic injuries, but their prevalence is increased in the setting of high-energy multiple trauma. In these circumstances, it is important for the orthopaedic clinician to recognize and appropriately treat the knee dislocation in parallel with other significant injuries. We report the case of an 18-year-old woman who was involved in a motor vehicle...
