Conflicting evidence exists regarding the ability of surgical helmet systems (SHSs) to reduce rates of infection after joint replacement. The purpose of this study was to investigate the use of SHS in…

Irrespective of surgical helmet system use, the surgical site infection and deep prosthetic joint infection rates were approximately 5% and 2.65% or so respectively, just like you just mentioned.

Perhaps the information is noted in the supplemental table one, but what was the most common organism identified in evaluating these infections?
In a total ankle arthroplasty infection cohort, Staph aureus was the most frequently isolated organism, which accounted for about 38% of the identified pathogens.
We also saw enterococcus and streptococcus species, along with a small number of polymicrobial infections.
Overall, the microbiologic profile is fairly consistent with what's been reported in both ankle arthroplasty and also larger joint arthroplasty literature.

Aside from surgical helmet systems, in over half of the cases, what other measures are routinely used at your institution to limit the risk of infection? You noted that the standardized perioperative infection prevention protocol included preoperative antimicrobial skin cleansing, nutritional and glycemic optimization, and anti-staphylococcal antibiotics within 60 minutes of incision.

Specific to my question, though, is does your group shave the lower extremity here from the operative extremity? And is an antibiotic typically mixed into the irrigation? And with regard to those two, do you think that these additional considerations even matter?
At our institution, the protocol is generally standardized across joint replacement procedures.
Hair at the operative site is trimmed in the preoperative holding area when necessary.
And typically, sterile saline is the most commonly used irrigation solution intraoperatively.
Because this was a retrospective study spanning multiple surgeons over more than a decade, we're not able to reliably capture every minor variation in operative techniques, such as irrigation practices and such.
My personal belief is that factors such as patient optimization, soft tissue management, periodic antibiotic administration, and adherence to standardized infection protocols likely plays a larger role as opposed to these individual factors.

I just was curious because we talked a lot about that in our home management meetings and trying to optimize patient care and limit infection.

In my opinion, your figure one complements the written text particularly well and is effective in displaying the study's total infections and management.

What is your team's protocol to ensure that a superficial infection is just that and does not extend to being a deep infection?
This is a critically important distinction, I think, in total ankle arthroplasty because management strategies differ substantially.
For patients with concern for deeper involvement, our institution maintains a relatively low threshold for aspiration, if possible, or just operative exploration because missing early prosthetic joint infection, as you know, can have significant consequences.
Ultimately, superficial infections in our cohort were limited to just the skin subcutaneous tissues without evidence of communication into the prosthesis.
