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.
