Comparative Study
Subchondral Bone Marrow Edema Had Greater Effect on Postoperative Pain After Medial Unicompartmental Knee Arthroplasty Than Total Knee Arthroplasty.
Although the relationship between pain and bone marrow edema (BME) in the osteoarthritic knee has been established, little is known about the effect of preoperative BME on postoperative outcomes after knee arthroplasty or if the influence of BME on postoperative outcomes differs between medial unicompartmental knee arthroplasty (UKA) and total knee arthroplasty (TKA). The purpose of this study was to compare pain, patient satisfaction, and revision rates between medial UKA and TKA patients with and without magnetic resonance imaging evidence of BME in the proximal tibia. ⋯ Preoperative BME did not influence TKA outcomes; however, pain scores for UKA patients with BME were worse both before and after surgery and fewer UKA patients with preoperative tibial BME were satisfied with their surgery.

In total joint arthroplasty (TJA) literature, there is a paucity of large cohort studies comparing chronic kidney disease (CKD) and end-stage renal disease (ESRD) vs non-CKD/ESRD patients. Thus, the purposes of this study were (1) to identify inhospital complications and mortality in CKD/ESRD and non-CKD/ESRD patients and (2) compare inhospital complications and mortality between dialysis and renal transplantation patients undergoing TJA. ⋯ Chronic kidney disease/ESRD patients had a greater risk of SSIs and wound complications compared to those without renal disease, and the risk of these complications was even greater in CKD/ESRD patients receiving dialysis. These findings emphasize the importance of counseling CKD patients about higher potential complications after TJA, and dialysis patients may be encouraged to undergo renal transplantation before TJA.

We examined the efficacy of implementing a multimodal program aimed at reducing the incidence of periprosthetic joint infection (PJI) after total joint arthroplasty (TJA) in a mid-size community hospital. ⋯ We found that formation of an IRC focused on evaluating and implementing strategies to reduce PJI following TJA can be effective.
