About this trial

The goal of this clinical trial is to compare the effects of a surgical and a non-surgical treatment method in patients with osteoarthritis in the proximal interphalangeal (PIP) joint. The main questions it aims to answer are:

* Are the treatments effective? * Is the surgical treatment more effective than the non-surgical treatment? Participants will receive surgical treatment (PIP joint denervation) or non surgical treatment (patient education plus exercise).

Researchers will compare the non-surgical and surgical groups to see if pain, patient-reported function, quality of life, movement and grip strength differs between the groups.
