Abstract
The number of hip and knee arthroplasty replacement surgeries is increasing steadily. In combination with demographic aging and the number of periprosthetic complications, this development has lead to the phenomenon where the need for revision surgery is rising. The problem is, that, while implantation procedures of hip arthroplasties are more or less standardized, explantation is a non-standardized task for experienced specialists, due to the unpredictability of the adequate loosening method. The surgeon often only gets to decide on which tools and methods may be applied to detach the prosthesis, only after getting access to the operation site. The time taken to detach the prosthesis is hardly predictable and mainly depends on the surgeons’ skills. To gain objective data on the mechanics of explantation, new measurement methods are required. One technical base for studies on revision procedures are standard force plates, available in biomechanics laboratories.
