Total knee joint transplantation has been performed in animal models and humans. This study investigates the impact of this operation on knee joint function in a dog model. Therefore, replantation was compared to transplantation during a 6-month follow-up period in four dogs in each group. ⋯ After 6 months, weight-bearing of all replant recipients was restored, but reduced in two transplant recipients with graft function. Full recovery after replantation, but impaired function after transplantation, was also reflected in the histological results: normal histological pictures of blood vessels, cartilage, bone and soft tissues were found in all replant recipients, but infiltrative vasculopathy indicating chronic rejection was found in the transplanted joints. The results of this animal study confirm that the procedure can lead to satisfactory functional results but also emphasize the need for perfect control of immunosuppression.

Case ReportsRotational acetabular osteotomy for severely dysplastic acetabulum.
The operative procedures chosen for arthrosis with severe acetabular dysplasia vary among orthopaedic surgeons. We operated on 250 hips using the rotational acetabular osteotomy (RAO) method of Ninomiya and Tagawa [8]. In this report, we describe the technique of RAO and the results of this procedure in patients with severely dysplastic hips. ⋯ After acetabular osteotomy with straight and curved osteotomes, smooth inferolateral rotation could be done in all cases. At the latest follow-up symptoms were improved remarkably, especially pain. Radiographically, adequate coverage of the femoral head was achieved and joint congruence improved in all 6 hips.

Case ReportsOperative treatment of mallet finger due to intra-articular fracture of the distal phalanx.
Treatment of a mallet finger due to an intra-articular fracture of the distal phalanx involving one-third or more of the articular surface is controversial. Thirty-three digits with such fractures were treated by open reduction and internal fixation with Kirschner wires. Of these 33 fractures, 13 were associated with subluxation of the distal phalanx. ⋯ Radiographs of the distal joint in 27 digits appeared normal, while in the remaining 6 digits, slight degenerative changes were noted. In one there was a minor surgical complication. By using the operative technique described, a congruous reduction of the inta-articular fracture and satisfactory function were achieved.

Case ReportsOperative treatment of destructive spondyloarthropathy of the lumbar spine in a patient on chronic dialysis.
We present a patient with end-stage renal disease treated by chronic dialysis, in whom progressive destructive spondyloarthropathy of the lumbar spine was successfully managed by fusion with internal fixation, resulting in relief of pain and restoration of activity.

This report presents the case of an 8-year-old boy who underwent a second clubfoot operation following early-stage reflex sympathetic dystrophy (RSD). After other conditions had been ruled out, the patient was submitted to physiotherapy supported by antiphlogistic and analgesic drugs as well as a partial immobilisation of the affected extremity. ⋯ RSD in children is not a well-recognised entity. This case of early-stage RSD illustrates the need to be aware of this possible complications after operation in the differential diagnosis of local pain and swelling of a limb.
