Therapy & Investigation



Any kind of medical intervention crossing the borders of the human body, such as operations, for example knee surgery, may cause unwanted effects.


Hemarthrosis (Accumulation of blood in the joint): The joint becomes swollen and rigid after the operation. This state can be treated efficiently by elevating the extremity and cooling with an ice pack. Repeated surgical exposure of the joint and elimination of the source of bleeding are only rarely necessary.


Infection: In the course of any surgical intervention, like in cases of operations on the knee, pathogen microorganisms may penetrate into the wound. This occurs only in a negligibly small fraction of the cases, thanks to the closed operation technique, modern ways of sterilization and strictly adherence to the general rules of performing an operation.
Signs of infection are high fever and swelling 2-7 days after surgery. It is essential to contact your doctor immediately. In such cases, we perform aspiration of the joint and confirm the presence and type of infection. In case of purulent infection, immediate surgical intervention, rinsing of the joint is necessary. In the course of the operation, we introduce thin tubes (drainage tubes), which allow rinsing of the joint. Also immobilization of the joint is important.


Phlebitis, thrombosis: Phlebitis or thrombosis of the lower extremities occurs particularly in corpulent patients with dilated veins; this means the occlusion of the veins caused by a blood clot. This may result in swelling and pain of the lower leg or thigh. Also taking contraceptive pills and smoking increase the risk of this complication. In order to prevent this, all patients receive a preventive injection prior to each operation, which, after appropriate training should be administered daily by the patients themselves for a defined period.


Neural palsy: Bleeding is prevented by the use of an inflatable tourniquet applied around the extremity, thus providing good joint visibility during the course of the operation. If the operation takes longer than expected, this compression may suspend nerve conductivity, resulting in weakness of some muscles. In most cases, this disappears in a few days.
