Between 1999 and 2001 thirty knees underwent a semitendinosus tendon plasty to recreate the medial patellofemoral ligament for recurrent patellar dislocation. The mean follow-up was 38 months. The mean improvement of the patellofemoral congruence angle after surgery was 14 +/- 7 degrees. All patients ended up with a full range of motion, except one patient, whose flexion was limited to 120 degr...

Cathepsin K is a cysteine protease that plays an essential role in osteoclast function and in the degradation of protein components of the bone matrix by cleaving proteins such as collagen type I, collagen type II and osteonectin. Cathepsin K therefore plays a role in bone remodelling and resorption in diseases such as osteoporosis, osteolytic bone metastasis and rheumatoid arthritis. We examin...

OBJECTIVE To evaluate the nature of positional changes of humeroulnar (HU) and humeroradial (HR) joints in a cohort of 74 patients with seropositive and erosive rheumatoid arthritis (RA) followed up prospectively. METHODS At the 15 year follow up standard anteroposterior and lateral radiographs of 148 elbow joints were evaluated. The mediolateral HU angle of the elbow was measured from antero...

Larsen syndrome is characterised by congenital anterior dislocation of the knees, associated with other joint dislocations, and a characteristic facies. Autosomal recessive and dominant inheritance have been proposed. A brother and a sister with consanguineous parents, suggesting autosomal recessive inheritance, were found to have the typical features of Larsen syndrome. In addition, they had s...
