Longer operative times may be required in complex total knee arthroplasty (TKA), however little is known about outcomes in procedures performed rapidly. We analysed 58,009 primary TKAs from the New Zealand National Joint Registry. The mean surgical duration was 89 minutes, and 50% of procedures lasted between 60 and 89 minutes. There was no difference in adjusted revision rates for groups lasting between 40 and 120 minutes, however procedures lasting >120 minutes had significantly higher revision rates. There was a higher revision rate in TKAs lasting <40 minutes (0.71 vs 0.48 revisions per 100 component years) but this was not statistically significant (P = 0.1). For primary TKAs lasting less than 120 minutes, further shortening operative time did not improve outcome, and very rapid procedures (<40 minutes) may lead to an increased risk of revision.

Attention Score in Context
Attention Score in Context
This research output has an Altmetric Attention Score of 4. 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 04 July 2022.
All research outputs
#7,960,512
of 25,374,917 outputs
Outputs from The Journal of Arthroplasty
#1,947
of 4,623 outputs
Outputs of similar age
#71,692
of 235,687 outputs
Outputs of similar age from The Journal of Arthroplasty
#18
of 50 outputs
Altmetric has tracked 25,374,917 research outputs across all sources so far. This one has received more attention than most of these and is in the 67th percentile.
So far Altmetric has tracked 4,623 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 7.9. This one has gotten more attention than average, scoring higher than 56% 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 235,687 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 68% of its contemporaries.
We're also able to compare this research output to 50 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 62% of its contemporaries.
