Purpose: Thumb basal joint arthritis is a common degenerative condition of the hand that is often managed with thumb basal joint arthroplasty (BJA). This procedure generally results in a high level of patient satisfaction; however, the rate and cause of early unplanned reoperation after thumb BJA are not well-understood. Therefore, we performed a review to better understand the rate and cause of early reoperation. Methods: A retrospective review of all thumb BJA cases performed at a single private academic center between 2014 and 2016 yielded 637 patients and 686 primary thumb BJAs with a minimum 1-year follow-up (mean, 2.4 years). Data collection included patient demographics, surgical technique and type of thumb BJA performed, time to reoperation, reason for early reoperation (within 2 years), and type of reoperation. Results: Of 686 patients undergoing thumb BJAs, 10 had unplanned early reoperation (1.5%). Mean duration between the index procedure and reoperation was 5.2 months (range, 0.5–14.3 months). Of the 10 unplanned early reoperations, 4 thumbs in 4 patients required revision arthroplasties owing to persistent pain. Time to reoperation for revision arthroplasty was 9.6 months (range, 3.9–14.3 months). Three of 10 reoperations resulted from early infection, 2 from unplanned early removal of symptomatic K-wires, and one from radial sensory neuritis. Conclusions: In this series of nearly 700 consecutive cases, we identified an unexpected early reoperation rate of 1.5%, with only a 0.6% reoperation rate specifically for painful subsidence requiring a revision arthroplasty. Mean time to revision was 9.6 months. These rates are lower than those published previously and should be considered by patients and surgeons when planning thumb BJA.
