Preop PPI exposure linked to higher revision and PJI after primary total elbow arthroplasty

In a propensity-matched retrospective cohort of adults undergoing primary TEA, preoperative PPI exposure did not affect 90-day outcomes but increased later complications. By one year, PPI users had higher revision risk (HR 1.87) and higher PJI risk (HR 1.81). Within 5- and 10-year windows, PPI exposure was associated with higher hazards of revision, PJI, loosening, fracture, and VTE. The authors propose PPI use may mark elevated risk and recommend preoperative optimization and targeted postoperative surveillance. 1

Early-adopter surgeons report high perceived utility and manageable workload for Mako robotic rTSA

A cross-sectional survey of 14 limited-release surgeons found strong agreement that Mako rTSA improves positioning accuracy and plan fidelity. NASA-TLX scores indicated low mental demand and high self-rated performance, with moderate physical demand and temporal pressure. Temporal demand was higher for less experienced users and decreased with experience (Spearman ρ = -0.63, p = 0.016). Forty-three percent experienced at least one workflow conversion, all due to registration or coracoid array issues. 2

Multicomponent mHealth program increased sit-to-stand transitions but did not reduce overall sedentary time after TKR

In an RCT of adults within one year of TKR (N = 83), the NEAT!2 app plus coaching did not reduce total sedentary time or improve most outcomes at 2 or 5 months. At 5 months, the intervention increased sit-to-stand transitions compared with control (mean difference 4.06 transitions; P = .04). Greater app engagement correlated with higher moderate-to-vigorous activity (r = 0.335; P = .04). Retention was high (96% at 2 months), suggesting feasibility but limited clinical effect on overall activity levels. 3
