[Knee dislocation treatment with temporary tibio-patellar fixation (patellar olecranization)].

Four patients with traumatic dislocation of the knee has been treated with olecranization of the patella. Mean age was 44.4 years (range 27-75 years). Three of them were politrauma patients, but none had popliteal artery injury or peroneal nerve palsy. Olecranization of the patella was performed on the day of injury. Results were assessed according to the Marshall scale. Three results were rated excellent and good with near normal knee function. In one case result was rated fair since despite stable knee and full range of motion pain persisted and marked vascular changes, not related to the injury were present.

Total knee dislocation due to rotatory malalignment of tibial component: a case report.

Dislocation of a total condylar knee replacement occurred because of rotatory malposition of the tibial component. The dislocation was evaluated by open operation and in the laboratory. It can be prevented by: directing the tibial component at the tibial tubercle; not using the posterior edge of the tibia to align the tibial component; recognizing the "contradictory rotation" of the tibia. At operation the tibia externally rotates with flexion and lateral patellar dislocation for exposure. However, the screw-home mechanism in normal gait causes the tibia to internally rotate with flexion. This difference of rotation increases the likelihood of dislocation. Other problems caused by rotatory malposition of the tibial component are: patellar subluxation in a hinged knee prostheses; patellar malalignment, patellar pain and possible prosthetic patellar loosening; abnormal eccentric loading of the tibial component and subsequent tibial-component loosening in all knee prostheses.

[Ultrasound diagnosis of congenital knee dislocation].

Since 1990, more than 50 children with hyperextended knee joints have been treated based on sonographic assessment. Ultrasound imaging has been useful for primary diagnosis, classification, and follow-up of conservative treatment. The image quality of sonographic documentation more or less equates the more expensive magnetic resonance imaging (MRI) and has become the golden standard of imaging hyperextended knee joints. There is almost no more need for plain X-rays.

Congenital bilateral hip and knee dislocation treated without surgery: 18-year follow-up.

Report of an 18-year-old black girl successfully treated for congenital dislocation of the hips and knees is presented. Progress from date of birth, methods of treatment, and results are given. It is concluded that the condition is unusual, that dysplasia and intrauterine forces are the cause, that early treatment gives excellent results without surgery, and that follow-up through the entire growth period is essential.

[Treatment of knee dislocation after callus distraction of the femur--a case report].

We report on the therapy of a complete ventrocranial luxation of the knee joint with leg shortening of 20 cm, which had appeared after diaphyseal distraction osteogenesis in the left thigh at the age of 7 years. The patient presented herself in our clinic at the age of 14 years. After application of an llizarov external fixator,first the luxation was gradually repositioned and afterwards arthrodesis of the knee joint was carried out. After consolidation of the arthrodesis, we removed the external fixator and carried out a unilateral, diaphyseal callus distraction in the left femur. The consolidation of the distraction callus of 12 cm was completed after 9 months and the fixator was removed. At the age of 18 years, 2 years after the treatment was completed, the patient was free of pain and able to walk safely. The remaining shortening of the left leg amounted to 2.5 cm and was balanced in the shoe proportionately.
