The primary objective of this study is to identify determinants of long-term patient satisfaction after hand reconstruction using silicone metacarpophalangeal arthroplasty (SMPA). The investigators hypothesize that appearance of the hand, ulnar drift, range of motion, pain, hand function and intake of the newer antirheumatic drugs (i.e. biologicals) influence patient satisfaction.
This is an ambidirectional, monocenter research project consisting of a retrospective chart review and a prospective cohort project.
Participants fulfilling all of the following inclusion criteria are eligible for the project:

| Satisfaction with the treatment result assessed on a 5-point Likert Scale | The primary outcome is the satisfaction with the treatment result at least one year after surgery and its determinants. It will be quantified using this question: How satisfied are you with the overall result of the SMPA surgery? The response options are: Very satisfied (score 1), somewhat satisfied (score 2), neither satisfied nor unsatisfied (score 3), somewhat unsatisfied (score 4), very unsatisfied (score 5). For further analyses, this question can be dichotomized into the categories of "satisfied patients" (very satisfied / satisfied) and "unsatisfied patients" (neither satisfied nor dissatisfied or worse). | at least one year after surgery |
