Osteomyelitis variolosa is an infection of bone and joints by smallpox virus variola major, most commonly in the elbows, wrists, ankles, hands, and feet. We report one such case in a 70-year-old woman who presented with deformities of the right knee, both elbows and ankles, and the left hand, and a history of childhood fever with rashes. Her lateral femoral condyle of the right knee was hypopla...

Total Knee Replacement is used to treat pain, stiffness and reduced range of movement. It has been estimated that a minimum of 90 degrees of range of motion in the knee is required for normal activities of daily living. In this article we demonstrate a technical note with a small patient series about the methods of treating knee stiffness after Total Knee Replacement.

A three-dimensional dynamic simulation of walking was used together with induced position analysis to determine how kinematic conditions at toe-off and muscle forces following toe-off affect peak knee flexion during the swing phase of normal gait. The flexion velocity of the swing-limb knee at toe-off contributed 30 degrees to the peak knee flexion angle; this was larger than any contribution f...

a month. Gradually the swelling subsided and he commenced to get about again. For some time, the knee swelled after walking for any length of time. This, too, had ceased to occur for perhaps three months before coming for recruitment. He passed the medical examination, and was duly sent to a depot for training, where he had been eleven weeks doing all that was demanded of him, when he noticed t...

Between 1987 and 2006 we performed a modified Thompson's quadricepsplasty on 40 fracture-related stiff knees and followed the patients for a mean of 7.9 years (2 to 11.1). The factors affecting the final gain of movement were investigated. A total of 15 knees required lengthening of the rectus femoris. The mean flexion gain was 70.2 degrees (42.3 degrees to 112.5 degrees ). According to Judet's...

Patients with weakness or paralysis of the extensors of the knee, espe­ cially when this is associated with weakness or paralysis of the hip extensors, have great difficulty standing and walking. Many devices have been de­ signed to support the knees, ranging from simple gutter splints, plaster splints, and nonjointed bars to jointed knee braces with knee locks. Am­ bulation with a stiff knee i...
