Welche Aspekte sprechen für die Knieprothese bei der Gonarthrose?

Abstract

Arthritis of the knee joint is a widely spread degenerative disease, which as a rule progressively advances. The World Health Organization estimated that approximately 10 % of the world population over the age of 60 years suffer from symptomatic arthritis of the knee joint. The therapy options range from conservative treatment (e.g. physiotherapy, analgesics, weight reduction and joint injections) to surgery, such as total joint replacement. Total joint replacement is recommended if the patient suffers from nocturnal pain, pain at rest, immediately after weight bearing, if radiological signs of gonarthritis are visible and the clinical examination shows reduction of range of motion and instability of the ligaments. Depending of the degree of arthritis different types of protheses are available: unicompartimental, bicompartimental and if ligaments are unstable, constrained implants.
