Randomized Controlled Trial Comparative Study
Periarticular Injection After Total Knee Arthroplasty Using Liposomal Bupivacaine vs a Modified Ranawat Suspension: A Prospective, Randomized Study.
The purpose of this study is to compare liposomal bupivacaine to a modified (Ranawat) local injection for total knee arthroplasty (TKA). ⋯ Liposomal bupivacaine as a periarticular injection after TKA demonstrated similar pain levels, narcotic usage, and range of motion compared to a modified Ranawat suspension but improved walking distance.

How Much Do Adverse Event Rates Differ Between Primary and Revision Total Joint Arthroplasty?
It is not known which adverse events occur more commonly following revision than following primary total joint arthroplasty. ⋯ Public reporting of adverse events should be interpreted in the context of the differences between primary and revision procedures, and reimbursement systems should reflect the greater amount of postoperative care that patients undergoing revision procedures require.

Preoperative anemia is present in 20% of total joint arthroplasty patients. Current preoperative treatment options, including iron supplementation (FE) and erythropoietin (EPO), are expensive. Tranexamic acid (TXA) has been adopted as an intraoperative adjunct to decrease blood loss. Our hypothesis is that TXA is a cost-effective treatment compared to FE and EPO in anemic patients. ⋯ Tranexamic acid is significantly less expensive than FE or EPO as a treatment option for total joint arthroplasty patients presenting with preoperative anemia. It is a cost-effective adjunct for limiting transfusion rates in this patient population. We recommend that new preoperative anemia levels that necessitate preoperative intervention be established.
