Background: The outcomes of trapeziectomy with ligament reconstruction and tendon interposition (LRTI) compared to the trapeziectomy (T) alone or in combination with tendon interposition (TIA) in the treatment of osteoarthritis (OA) of the carpometacarpal joint (CMCJ) of the thumb are still debated. The aim of this study is to conduct a meta-analysis to determine whether the outcomes of LRTI were better compared to T or TIA. Methods: A meta-analysis of randomised trials that included the outcomes of patients with thumb CMCJ OA that underwent LRTI, T or TIA with at least 1 year follow-up. The outcomes included number of patients with pain 1 year after surgery (NPP), Visual Analog Scale for Pain (VAS Pain), key pinch strength, patient reported outcome measurements (PROMs) and number of adverse effect (AEs). The effect was assessed using mean difference for quantitative variables (VAS pain and key pinch), standardised mean difference for PROMs and relative risk for binary variables (NPP and AEs). Results: Seven studies met the inclusion criteria (857 participants: 438 LRTI vs 419 T/TIA). We did not find significant differences between LRTI and T/TIA in NPP, VAS pain, key pinch at 1 year and 5 years or more, PROMs, and AEs at 1 year and at 5 years or more after surgery. Conclusions: The outcomes of LRTI are not superior to T or TIA in the treatment of OA of the thumb CMCJ. Level of Evidence: Level I (Therapeutic).
