Abstract

Introduction  Surgical treatment of thumb trapeziometacarpal osteoarthritis usually involves 4 to 8 weeks of postoperative casting and splinting followed by varying mobilization protocols. Suspension arthroplasty has been described as an alternative to allow earlier range of motion exercises. The purpose of this study was to compare patient-reported outcomes (PRO) when adding a two-string suture-button suspension arthroplasty (Mini TightRope, MTR) to our usual procedure of ligament reconstruction and tendon interposition (LRTI), allowing early mobilization. Can we allow early mobilization using this technique without jeopardizing the PRO results at the 1 year follow-up and without an increased risk of complication? Materials and Methods  A prospective study using the MTR system (Arthrex) as a suture-button suspensionplasty was conducted. Twelve patients (MTR group) and 36 historical patients (LRTI alone) were included. Results  At 12 months, the median value for quick disabilities of the arm, shoulder, and hand was 11.3 (range, 0-43.2) in the MTR group and 13.6 (range, 0-88.6) in the LRTI group, resulting in similar improvements, p = 0.46. One in twelve patients in the MTR group was dissatisfied and 9 in 36 in the LRTI group were dissatisfied, p = 0.41. No complications were observed during the first year. Conclusion  Supplemental suture-button suspensionplasty can be utilized for high demand patients and patients who want to reduce immobilization time without major complications and with similar PRO as LRTI at 6 and 12 months. Level of evidence  Four case series.
