We report the dislocation of 6 liners out of the metal backing shells of Harris Galante II cementless total hip prostheses implanted between 1993 and 1996. The time between primary implantation and failure varied from 46 to 95 months. The dislocations were probably the result of suboptimal mechanical fixation of the polyethylene liner in the shell(More)
Fourteen patients were treated operatively for delayed union and nonunion of midshaft clavicular fractures from 1986 to 1994. Radiographically, nine nonunions were atrophic and five hypertrophic. The operative technique included opening the medullary canal, bone grafting, and fixation with an AO reconstruction plate. Postoperative mobilization started(More)
BACKGROUND Whether anterior cruciate ligament reconstruction retards the progression of osteoarthrosis is not established. Bone scintigraphy can be useful for monitoring the course of osteoarthrosis. Bone scan findings are abnormal in the majority of patients with anterior cruciate ligament deficiency. Three uptake patterns can be distinguished. (More)
A reattachment of the tibial remnant of the torn anterior cruciate ligament (ACL) to the posterior cruciate ligament is sometimes observed during surgery and apparently implies that the human ACL does have a healing response. The aim of this study was to investigate whether this reattachment tissue has similar histological characteristics of a healing(More)
Indications for total and unicondylar knee arthroplasty (KA) have expanded to younger patients, in which Patient-Reported Outcome Measures (PROMs) often show ceiling effects. This might be due to higher expectations. Our aims were to explore expectations of younger patients concerning activities in daily life, work and leisure time after KA and to assess to(More)
OBJECTIVE The objective of this study was to evaluate the incidence of radiographic osteoarthritis in the operated knee in comparison with the contralateral knee ten years after a bone-tendon bone patellar autograft ACL-reconstruction and to evaluate to which level patients regain activity ten years after reconstruction. METHODS Fifty-three patients with(More)
