Randomized Controlled Trial Multicenter Study Comparative Study
A randomized, double-blind, dose-ranging study comparing wound infiltration of DepoFoam bupivacaine, an extended-release liposomal bupivacaine, to bupivacaine HCl for postsurgical analgesia in total knee arthroplasty.
DepoFoam bupivacaine is a novel liposomal formulation of bupivacaine designed to provide prolonged postsurgical analgesia. This dose-ranging study evaluated extent and duration of analgesia following administration of DepoFoam bupivacaine in patients undergoing total knee arthroplasty (TKA). ⋯ Exposure to bupivacaine increased in a dose-related manner, as reflected by mean and maximum plasma bupivacaine concentrations, and AUC(0-∞). Treatment with DepoFoam bupivacaine 532 mg was associated with statistically significantly greater analgesia while patients were at rest after surgery compared with bupivacaine HCl.

Randomized Controlled Trial Comparative Study
Effects of knee bracing on postural control after anterior cruciate ligament rupture.
Randomized clinical trial. ⋯ Elastic knee braces increase postural stability by approximately 22% in patients with ACL rupture. There was no difference in postural stability between uninjured and injured legs in the braced condition. One possible explanation is that bracing improves both proprioception and postural control.
