Osteoarthritis of the Acromioclavicular Joint

The acromioclavicular joint is the joint between the collarbone and the roof of the shoulder. Osteoarthritis of the acromioclavicular joint refers to the occurrence of joint wear in this area. In osteoarthritis of the acromioclavicular joint, there is a thinning of the cartilage tissue forming the joint. As the articular cartilage thins, movements in the joint become painful.

When is surgery needed?

Surgery is recommended if osteoarthritis leads to inflammatory changes in the acromioclavicular joint or if wear-related enlargement of the joint results in impingement syndrome of the underlying structures.

What happens during surgery?

Surgery on the acromioclavicular joint is performed using a minimally invasive technique via joint endoscopy (arthroscopy). During this procedure, the joint space is widened by removing bone and/or bony growths.

Aftercare

Immobilisation is not necessary following such an intervention. Physiotherapeutic exercises are carried out according to a post-treatment programme. Incapacity for work following such a procedure is approximately 10 to 14 days for desk-based activities, and 4 to 6 weeks for physical labour.
