Differences in recovery time between trapeziectomy and carpometacarpal joint replacement: meta-analysis.
Synthesis in BJS open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThumb-base osteoarthritis is a common degenerative condition that produces symptoms including pain and reduced hand function. Trapeziectomy is the mainstay surgical intervention following failure of conservative management and steroid injection, with carpometacarpal (CMC) joint replacement anticipating faster recovery time and return to work. However, there is limited evidence on recovery following both surgeries, which affects patient counselling and future research design.
methodsA preregistered (CRD42023450865) systematic review of the literature was conducted according to the PRISMA guidelines. Disability of the Arm, Shoulder and Hand (DASH) questionnaire scores, grip strength, and key pinch strength scores were obtained at different timepoints during follow-up. Standardized mean changes (SMC) were calculated and pooled through random-effects meta-analysis before being plotted at monthly timepoints.
resultsOf 63 articles eligible for inclusion, 25 studies were included in the meta-analysis. Subgroup analyses were conducted comparing types of trapeziectomy, joint replacement implants, and immobilization protocols. At the 1-month follow-up, joint replacement was associated with a trend of improvement in the DASH score, whereas trapeziectomy was associated with a deterioration. At 12 months, joint replacement showed a trend of greater improvement in hand function than trapeziectomy. Key pinch strength returned to baseline function at 1.5 months after joint replacement, compared with 6 months after trapeziectomy. Newer dual-mobility implants were associated with a quicker trend of recovery in DASH and key pinch strength than single-mobility implants. However, confidence intervals overlapped considerably, and most study arms had a high risk of bias, so these findings should not be considered statistically significant.
conclusionThis study shows a trend towards faster early recovery after CMC joint replacement compared with trapeziectomy, although the evidence remains limited. Randomized clinical trials with systems to frequently capture patient-reported outcomes data are required to study the temporal course of recovery for both surgeries.
