OBJECTIVE To evaluate the approaches and procedures used by knee surgeons in Brazil for treating medial patellofemoral lesions (MPFL) of the knee in cases of acute traumatic dislocation of the patella. MATERIALS AND METHODS A questionnaire comprising 15 closed questions on topics relating to treating MPFL of the knee following acute dislocation of the patella was used. It was applied to Brazi...

Dislocation of revision total knee arthroplasty is a very rare, serious and difficult complication. Incidence of significant instability and dislocation following primary TKA ranged from 1% to 2% in the past ten years. This incidence has been lowered to 0.15% to 0.5% with the development of modern surgical techniques and posterior stabilized implants. It is very few reports have been published ...

In a chart review 31 traumatic knee dislocations were identified in 30 patients during an eight year period (1992-2000).Fifteen dislocations (48.4%) were posterior,seven anterior,eight occult and one medial.out of the five cases of vascular injuries three happened with posterior dislocations and in four patients associated ipsilateral limb injuries were present .the general incidence of simulta...

The umbilical cord was employed as a source of collagen in 10 children with congenital dislocation of hip. The amount of collagen and its solubility were measured in slices of the cords and in the umbilical veins and compared with the values in normal subjects. Both the amount of collagen and its solubility were decreased in children with congenital dislocation of the hip.

Congenital extensor tendon dislocation over the metacarpophalangeal joint is a rare condition. Here the author presents a patient with bilateral all fingers congenital extensor tendons dislocation over the metacarpophalangeal joints. A video demonstration and ultrasound images are shown to supplement this case.

We report a prospective study of the feasibility of employing specially trained physiotherapists to screen neonates for congenital dislocation of the hip. During ten years 42,241 babies were screened, using clinical tests; 255 were diagnosed and treated by a Pavlik harness. In the same period 13 children presented late with congenital dislocation of the hip which had not been detected by the sc...

Only two cases have been reported of congenital dislocation of the hip in infants born after extrauterine pregnancies. We report a further two and discuss the management and the variable outcome. These cases seem to confirm that congenital dislocation of the hip is associated with moulding forces rather than being a teratological abnormality.

Superior dislocation of the patella is a rare diagnosis. A 72 year old woman attended the accident and emergency department of the hospital with a painful right knee after a knock to the knee. Clinical examination and radiographs confirmed a superior dislocation of the patella, which was reduced and closed with the aid of simple analgesia. The authors present the case report and discuss the rel...

We are reporting a case of traumatic anterior dislocation of the left knee without any neurovascular complication. To our knowledge, such complete dislocation without involvement of popliteal artery and/or peroneal nerve has not been reported before however similar cases are reported after total knee replacement with and without neurovascular compromise. This injury was recognized and treated p...

Magnetic resonance imaging was used to analyse the patellofemoral relationships during the first 3O’ of knee fiexion in women with recurrent patellar dislocation. The patellofemoral joints were imaged both sagittally and axially with the knee flexed O , 1O , 200, and 3 O At the beginning of knee flexion the sulcus angle was greater than in unaffected women, the lateral patellofemoral angle was ...
