Total knee arthroplasty (TKA) is an effective treatment option for patients with end-stage haemophilic arthropathy of the knee. However, the procedure is technically challenging, as knee motion is often restricted before the operation and complication rates are then thought to be higher than for patients with a normal range of motion (ROM). There is very limited information on the outcome of TKA in haemophilic patients presenting with stiff knees. The objective of the present study was to retrospectively analyse and compare the clinical results after TKA in haemophiliacs with stiff and non-stiff knees. ⋯ TKA in haemophilic patients presenting with haemophilic arthropathy of the knee results in significant improvements in function and reduced pain. Although the ultimate clinical outcome in stiff knees is inferior to that with non-stiff knees, joint replacement surgery can be successfully performed in patients with restricted preoperative range of motion. Vy-quadricepsplasty for to facilitate exposure is associated with the development of a postoperative extensor lag and should therefore be performed restrictively. Patient satisfaction after TKA was equally high in the two groups.

In the late 1960s, the helicopter emergency medical service (HEMS) was established in Germany because of an increasing number of severe injuries in traffic accidents. To get a doctor quickly on scene was the initial intention, rather than transporting the patient. Today, rescue helicopters cover the entire field of emergency medicine and are an important transportation device for polytrauma patients. ⋯ For the multiply injured patient in particular, in over 40 % of the cases there is a joint patient care involving both helicopter- and ambulance-based emergency services. The HEMS undertakes especially the rapid, if necessary, even transregional transport to specialised trauma centres.

A sagittal spinal deformity can lead to a significant reduction in quality of life. A loss of lumbar lordosis, which may be degenerative or iatrogenic, is usually identified as the main driver for a sagittal imbalance. Re-lordosing the lumbar spine has the potential to correct a global sagittal imbalance. Different surgical techniques are available. The present video describes the pedicle subtraction osteotomy, which represents a powerful option for rigid and severe deformities. ⋯ The pedicle subtraction osteotomy represents a powerful surgical technique for correction of a sagittal spinal imbalance.
