What did studies of Arthroplasty find?
2Studies of Arthroplasty measured 2 outcomes; the most studied are plasma amyloid-beta oligomers (1 study) and lateral stability (1).

Plasma amyloid-beta oligomers

Arthroplasty has no effect on plasma amyloid-beta oligomers in humans.
“There was no significant perioperative change in MDS-Oaβ, suggesting surgery or anesthesia did not alter the plasma Aβ oligomerization tendency.”

What is Arthroplasty linked with?
1Studies link Arthroplasty with 1 measure, most often frailty index (1 study).

Frailty index is associated with arthroplasty in humans (not significantly affect risk of experiencing KA/HA except in female participants undergoing HA (hazard ratio 1.29, 95% CI 1.04-1.61)).
“Regardless of surgical site, frailty index scores did not significantly affect risk of experiencing KA/HA except in female participants undergoing HA (hazard ratio 1.29, 95% CI 1.04-1.61, P = 0.02).”
