We treated 34 patients with recurrent dislocation of the hip with a constrained acetabular component. Roentgen stereophotogrammetric analysis was performed to assess migration of the prosthesis. The mean clinical follow-up was 3.0 years (2.2 to 4.8) and the radiological follow-up was 2.7 years (2.0 to 4.8). At the latest review six patients had died and none was lost to follow-up. There were fo...

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...

Dislocation of the patella may be congenital, it may be due to injury, or it may be simply habitual or recurrent, with some basic defect in the anatomy of the knee region. This review concerns the recurrent type, occurring either spontaneously or after minor injury. Patients with recurrent patellar dislocations may have any ofthe following abnormalities: I ) a high-riding patella with an elonga...

BACKGROUND The present study aimed to describe a new safe and economical technique for medial patellofemoral ligament (MPFL) reconstruction with satisfactory clinical outcomes, and present the results of a four-year follow-up. MATERIAL AND METHODS Thirty-two patients with recurrent patella dislocation, who underwent MPFL reconstruction with two semi-patellar tunnels and hardware-free patellar f...
