A survey study was performed of individuals in an orthopedic clinic waiting room regarding their knowledge of Medicare reimbursement to orthopedic surgeons for primary THA and TKA. A total of 1200 surveys were submitted by individuals (median age 64 years, 61% female, 50% with Medicare as their primary insurance and 29% having had THA or TKA). ⋯ Most respondents were willing to wait 3-7 weeks for surgery to be performed. Participants tended to value THA and TKA more relative to Medicare payments and tended to overestimate Medicare reimbursement to surgeons for THA and TKA.

Randomized Controlled Trial
Dexamethasone reduces length of hospitalization and improves postoperative pain and nausea after total joint arthroplasty: a prospective, randomized controlled trial.
Controlling postoperative pain and nausea after total joint arthroplasty remains an important challenge. We conducted a prospective, randomized controlled trial with 120 patients to determine if the addition of perioperative dexamethasone to a multimodal regimen improves antiemetic and analgesic control, enhances mobility, and shortens hospital length of stay after total hip and knee arthroplasty. ⋯ A second, 24-hour postoperative dose of 10mg intravenous dexamethasone provided significant additional pain and nausea control and further reduced length of stay (P<0.05). No adverse events were detected with the administration of the intraoperative and/or postoperative dexamethasone.

Randomized Controlled Trial
A prospective double-blind placebo controlled trial of topical tranexamic acid in total knee arthroplasty.
Tranexamic acid (TNA) reduces postoperative blood loss in general and obstetrical surgery but there is limited orthopaedic literature regarding its use in the topical setting. To study the effect of topical TNA after primary total knee arthroplasty (TKA), 101 patients were randomized to topical administration of 2.0g TNA in 75mL of normal saline (50 patients) or placebo (51 patients). ⋯ Total blood loss was lower in the TNA group (940.2±327.1mL) than the placebo group (1293.1±532.7mL)(P<0.001), and four patients in the placebo group and none in the TNA group received postoperative transfusion (P=0.118). We recommend administration of topical TNA in primary TKA in healthy patients to decrease perioperative blood loss.

Randomized Controlled Trial
Effects of combined application of muscle relaxants and celecoxib administration after total knee arthroplasty (TKA) on early recovery: a randomized, double-blind, controlled study.
The purpose of this study was to evaluate the effectiveness of application of muscle relaxants and celecoxib in early recovery after total knee arthroplasty (TKA). One hundred and fifty patients were randomized 1:1:1 to receive either both of muscle relaxants and celecoxib or muscle relaxants alone or placebo for 2 weeks (50 patients in each group). ⋯ Group A improved better with reduced VAS pain scores compared with another two groups. These results demonstrated that application of muscle relaxants and celecoxib into patients undergoing TKA for 2 weeks postoperative consequently improved their convalescence.
