Bony coverage by the patellar button was inversely associated with shear strength. Surgeons should consider opting for a smaller size patella, which may improve the maximum shear strength of the patellar construct.

Timing of DAIR for acute TKA PJI within early windows did not significantly affect failure or complication rates, suggesting that urgent, rather than emergent, intervention is appropriate.

GLP-1RA use was associated with improved early surgical outcomes and decreased resource utilization following TJA. These findings suggest a potential benefit of GLP-1RA use for optimizing high-risk patients who have obesity or diabetes undergoing TJA.

Plasma bacteriophage cfDNA offers a promising approach to detect and monitor staph PJI. The persistence of these Staph bacteriophages in prior PJI may reflect subclinical infection or residual microbial DNA undetectable by standard diagnostics.

The ceramic-on-ceramic resurfacing at 2yr postop demonstrates promising results with satisfactory outcomes in all recorded PROMs. Further long-term data are needed to support the widespread adoption of this prosthesis as an alternative to other bearings.

In patients, >75yo, undergoing aseptic revision THA with modular fluted tapered stems, the cumulative incidence of reoperation was 6.1% at 2yr. The MFT stem remains an acceptable option in older patients undergoing aseptic revision THA.

Patients who had symmetric tibial augment constructs exhibited similar rates of radiolucency but higher survivorship compared to those with asymmetric constructs overall. However, when metaphyseal cones were utilized, survivorship was equivalent.

Precollapse AVN, core decompression combined with allograft-bone threaded cage or mineralized collagen threaded scaffold demonstrated comparable long-term survivorship and functional outcomes, though both their efficacy diminished in advanced stages.

A R-THA for instability presents ongoing challenges with high reoperation and rerevision rates. Patient optimization (e.g., smoking cessation), acetabular component revision when appropriate, and implantation of DM or CL should be considered.

There was a high rate of patients that demonstrated C acnes colonization prior to THA. Preop surgical prep was not effective at decreasing the burden of C acnes from the surgical site prior to THA, and different skin preparations should be considered.

The surgical complication risk of cementless HA for FNF is higher than cemented HA, with an 11-fold increased risk of ppfx compared to cemented HA.

At 15yr, patients ≤30yr undergoing modern THA showed high survivorship. Factors associated with increased complexity, such as the use of cemented stems, preop infection, and extended approaches, were associated with higher failure rates.
