Background and purpose: Extensive damage to the wrist joint greatly impacts functionality and reduces quality of life, especially when accompanied by severe persistent pain. Debate is ongoing regarding the pros and cons of total wrist arthroplasty compared to wrist arthrodesis, and data regarding the results of wrist arthroplasty remains inconclusive. Current fourth-generation implants show considerably improved results, but few studies report on long-term results and fewer still compare these results with pre-operative assessments of function and pain. By evaluating the results of 60 Universal 2 and Freedom wrist implants and comparing pre- and postoperative scores this study aims to establish the long-term outcomes of these prostheses. Methods: This study is an observational prospective cohort study. Patients were assessed for pain levels, asked to fill in questionnaires (QuickDASH, PRWHE and GPE) and measurements of grip strength as well as range of motion were conducted, before and after surgery. Pre- and postoperative data were compared. Results: A significant reduction in pain was observed, p=0.035. Patient satisfaction was high, as 92% stated they would opt for the procedure again. QuickDASH and PRWHE scores improved significantly, and both exceeded the Minimal Clinically Important Difference. Grip strength did not exceed preoperative levels, and range of motion did not significantly improve though minimal functional range of motion was achieved in most cases. Prosthesis survival was calculated to be 95.6% at 5 years and 78.8% at 7.5 years. With 14 patients needing treatment for complications in the first 5 years after surgery, complication rate was high. Conclusion: The Universal 2 and Freedom prostheses offer reliable pain relief and preservation of functional range of motion and grip strength. Despite relatively high complication and revision rates, continued use of these prostheses is warranted.
