The impact of COVID-19 on hip and knee arthroplasty surgical volume in China.
Article in International orthopaedics, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
purposeThe reduction of hip and knee arthroplasty surgical volume has been reported in many countries during the COVID-19 pandemic. In China, there is no national joint registry system and the impact of COVID-19 towards surgical volume remains unclear. The aim of this study was to investigate the hip and knee arthroplasty surgical volume in China during the pandemic and evaluate its change trends.
methodsAnnual sale numbers of prostheses used in total knee arthroplasty (TKA), total hip arthroplasty (THA), and femoral head replacement (FHR) from 2011 to 2021 was collected from providers registered in National Medical Products Administration (NMPA). Annual surgical volume of TKA, THA, FHR, unicompartmental knee arthroplasty (UKA), and revision of hip/knee arthroplasty (RJA) was collected from member hospitals of Beijing Joint Society (BJS). We used linear regression to estimate the loss of surgical volume. Annual surgical volume obtained from Britain and Australian joint registries were used to make comparison.
resultsIn China, the surgical volume of THA/FHR, TKA, and UKA in 2020 all decreased compared to the predicted value, with a reduction of 82,525 cases (13.46%), 165,178 cases (33.50%), and 151 cases (0.65%), respectively. All the three procedures showed significant recovery in 2021. The surgical volumes of THA/FHR and UKA were 68,813 and 9402 cases higher than predicted levels, respectively, while TKA volume remained slightly below the predicted level. The regional statistics in Beijing showed similar change mode. In 2020, the surgical volume of THA/FHR, TKA, FHR, and UKA all decreased compared to the predicted value, with a reduction of 5031 cases (43.37%), 5290 cases (40.69%), 620 cases (29.18%), and 925 cases (39.11%), respectively. In 2021, with the exception of FHR, the number of these procedures increased compared to 2020, but remained below the predicted value. Compared with the data from Britain and Australia, China experienced less reduction and faster recovery in the proportions of elderly people (> 65 years old) who undergo hip and knee arthroplasty during the COVID-19 pandemic.
conclusionDuring the COVID-19 pandemic, although hip and knee arthroplasty surgical volume in China showed a similar "restoration-recovery" change pattern with other countries, China took fewer losses in this field.
