Abstract

The successful pain-relieving treatment of highly symptomatic osteoarthritis in a national karate coach with Arthrosamid is described in this case report. This type of treatment had previously only been used in cases of gonarthrosis. The extensive conservative and arthroscopic treatment that had previously been carried out had not resulted in a sustained reduction in pain. A single off-label injection of 3 ml of a 2.5% polyacrylamide hydrogel (Arthrosamid) was administered. The injection was performed under CT guidance. A significant analgesic effect occurred rapidly and was long lasting. A follow-up MRI scan did not reveal any structural changes. If the manufacturer’s instructions are followed, Arthrosamid represents a therapeutic option for the treatment of advanced osteoarthritis. A prerequisite for the therapy is that the joint capsule and the rotator cuff are intact so that Arthrosamid can have an effect in the affected joint. A single course of oral antibiotics is a prophylactic measure immediately prior to injection.
