Total knee arthroplasty not always necessary for severe knee osteoarthritis
Sometimes a partial prosthesis is sufficient for patients who need an artificial joint due to severe osteoarthritis of the knee. This is pointed out by the German Society for Endoprosthetics (AE). The prerequisite is that the cruciate ligaments remain intact and the cartilage damage is limited exclusively to one section...
How long do revised and multiply revised knee replacements last?
A retrospective observational study of the National Joint Registry Knee replacements are common and effective operations but patients that undergo this intervention are at risk of needing subsequent costly and often complex revision surgery with poorer outcomes than primary surgery. The treatment pathway over the life of the patient in...
Hip replacement: virtual surgical training with haptic technology (Interview)
Surgeons have only limited options to practice surgical techniques before they enter the operating room. The implantation of an endoprosthesis requires extensive practical training since it necessitates strength and utmost precision. The "Dynamic HIPS" project develops a virtual reality hip implant simulator that provides realistic haptic feedback. The project has been running...
Evidence- and consensus-based indication criteria for total hip arthroplasty for coxarthrosis
Implantation of a total hip arthroplasty (hip TEP) is the most common endoprosthetic procedure in Germany. However, there are significant regional differences in the frequency of treatment. Despite predominantly very good results, risks are also associated with this intervention. The correct indication is therefore of great importance for the individual...
Magnet-controlled bioelectronic implant could relieve pain
A team of Rice University engineers has introduced the first neural implant that can be both programmed and charged remotely with a magnetic field. The integrated microsystem, called MagNI (for magnetoelectric neural implant), incorporates magnetoelectric transducers. These allow the chip to harvest power from an alternating magnetic field outside the...
