Congenital dislocation of the knee was described by Chatelaine in 1822 (quoted by Shattock 1891) and then by Bord in 1834 (quoted by Forgon and Szentp#{233}tery 1961). It was at first thought to be more common in girls, but in a review of a larger series of cases the sex distribution was found to be equal (Provenzano 1947). Kopits (1925) reviewed 2,393 patients with congenital anomalies and fou...

Objective The aim of this study was to ultrasonographically measure the dimensions proximal and distalpatellar fragments determine whether postoperative growth differences existbetween in children with congenital dislocation kneetreated by Niebauer Kings quadricepsplasty. Methods This retrospective included six congenitaldislocated knees four arthrogryposis multiplex congenita (AMC)(3 girls; me...

Correspondence to: Dr Parfitt. A 9 year old boy presented to the accident and emergency department with a painful, tender swollen right knee. He had fallen 4 feet from a wall and struck his knee on the edge of a kerb. On examination the knee was held in a 45 degrees of fixed flexion. A 10 cm horizontal laceration extending to deep fascia was evident. Radiography (see fig 1) revealed the patella...

Thirty-five patients with habitual dislocation of the patella in flexion were reviewed; eight were bilaterally affected. Each had undergone quadricepsplasty with an average follow-up of 6 years 9 months. Bands or contractures, most commonly in vastus lateralis, the iliotibial tract and rectus femoris were seen in each. Redislocation was seen in 12 knees. At review, 79% of the knees were normal....

BACKGROUND The treatment of acute patellar dislocation in children is controversial. Some investigators have advocated early repair of the medial structures, whereas others have treated this injury nonoperatively. The present report describes the long-term subjective and functional results of a randomized controlled trial of nonoperative and operative treatment of primary acute patellar disloca...

The implications of a diagnosis of congenital dislocation of the hip and the importance of the role of the family physician in early detection and treatment are identified.A review of the salient clinical features of congenital dislocation of the hip is undertaken. The results of a survey carried out in the author's practice on an unusual incidence of congenital dislocated hip are reviewed.

Small patella syndrome (SPS) is characterized by aplasia or hypoplasia of the patella and pelvic girdle abnormalities, including bilateral absence or delayed ossification of the ischiopubic junction and infra-acetabular axe-cut notches. Here, we report a case of SPS in a 26-year-old female. Magnetic resonance image (MRI) showed a small patella with thick eccentric non-ossified patellar cartilag...

The medial soft-tissue restraints of the patella, specifically the medial patellofemoral ligament and the vastus medialis obliquus muscle, are critical to patellofemoral joint stability. A reliable and inexpensive imaging technique would be clinically useful especially after acute patellar dislocation. The medial patellofemoral ligament and the vastus medialis obliquus muscle were identified in...

Removal of the patella has been recommended for recurrent dislocation, but it has not been emphasised that this operation has distinct advantages over “ realignment “ procedures. I now regard removal of the patella as essential. Unsuccessful results have been reported for the reason that the regenerated patella, or the fibrous tissue in which it forms, has continued to slip over the femoral con...
