| Abstract |
This meta-analysis compared infection and revision rates in patients with rheumatoid arthritis (RA) and osteoarthritis (OA) who underwent total knee arthroplasty (TKA). Rates of superficial wound and deep periprosthetic infections were compared in the groups, as were whether revision rates associated with infectious and noninfectious causes differed in the RA and OA groups. Studies were included in the meta-analysis if they (1) compared infection and revision rates after primary TKA in RA and OA patients; (2) directly compared superficial wound and deep periprosthetic infection rates in RA and OA patients who underwent primary TKA; and (3) reported the actual numbers of RA and OA patients who underwent TKA and developed postoperative infection and/or required revision. The rate of superficial wound infections after primary TKA was similar in the RA and OA groups (15/258 [5.8 %] vs. 77/1609 [4.7 %]; odds ratio [OR] 1.12, 95 % confidence interval [CI] 0.36-3.46; P = n.n.), but the deep infection rate was significantly higher in RA than in OA patients (229/7651 [3.0 %] vs. 642/68628 [0.9 %]; OR 2.04, 95 % CI 1.37-3.05; P < 0.001). The proportion of subjects who required revision resulting from infection after TKA was significantly higher in the RA than in the OA group (86/8201 [1.0 %] vs. 555/118755 [0.5 %]; OR 1.89, 95 % CI 1,34-2.66; P < 0.001), whereas the proportion of subjects requiring revision due to noninfectious causes did not differ significantly (46/594 [7.7 %] vs. 52/904 [5.7 %]; OR 1.22, 95 % CI 0.74-2.00; P = n.n.) CONCLUSION: Following primary TKA, RA patients had a significantly higher rate of deep periprosthetic infections than OA patients, but their superficial infection rates were similar. The revision rate due to infectious causes was significantly higher in RA than in OA patients, but their revision rates due to noninfectious causes did not differ. Therefore, the surgeon should fully explain to RA patients scheduled to undergo primary TKA that, compared to OA patients, they are more likely to experience a deep infection postsurgery.

Attention Score in Context
This research output has an Altmetric Attention Score of 6. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 01 June 2013.
All research outputs
#5,805,475
of 23,007,053 outputs
Outputs from Knee Surgery, Sports Traumatology, Arthroscopy
#717
of 2,675 outputs
Outputs of similar age
#90,315
of 335,555 outputs
Outputs of similar age from Knee Surgery, Sports Traumatology, Arthroscopy
#12
of 47 outputs
Altmetric has tracked 23,007,053 research outputs across all sources so far. This one has received more attention than most of these and is in the 74th percentile.
So far Altmetric has tracked 2,675 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.1. This one has gotten more attention than average, scoring higher than 73% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 335,555 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 72% of its contemporaries.
We're also able to compare this research output to 47 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 74% of its contemporaries.
