Ligament reconstruction tendon interposition (LRTI) and suture-button suspensionplasty (SBS) are both common treatment options for trapeziometacarpal osteoarthritis. The primary purpose of this systematic review was to compare the subjective improvement in patient-reported outcomes in regard to disability for patients undergoing LRTI and SBS for trapeziometacarpal osteoarthritis. A secondary purpose was to compare the subjective improvement, objective outcome scores, and complication rates following both procedures. We performed a systematic review using PubMed, Scopus, and Embase to compare the clinical outcomes of LRTI and SBS. Inclusion criteria were level I-IV evidence articles reporting postoperative Disabilities of the Arm, Shoulder, and Hand (DASH) or QuickDASH scores. Study methodological quality, risk of bias, and recommendation strength were assessed. This systematic review included 31 studies for final analysis with 1289 thumbs undergoing LRTI (25 studies) and 113 thumbs undergoing SBS (6 studies). Both procedures demonstrated similar improvement in DASH and/or QuickDASH scores, while key pinch and grip strength inconsistently improved following both procedures. Complication rate was similar between the 2 procedures; LRTI 12% and SBS 13%. Although both LRTI and SBS seem to provide improved short-term patient-reported functional improvement and objective strength, there was significant heterogeneity within the included studies, and those studies discussing SBS were of lower quality evidence than those of LRTI. Thus, to truly delineate whether a difference exists between these 2 techniques for the treatment of first carpometacarpal joint arthritis, larger prospectively designed studies of high-quality evidence are necessary.
