The merits of cell salvage in arthroplasty surgery: an overview.

Arthroplasty entails considerable exposure to allogenic blood transfusion. Cell salvage with washing is a contemporary strategy that is not universally used despite considerable potential benefits. We searched Embase and Medline to determine if blood salvage with washing during primary and/or revision hip and knee arthroplasty results in lower rates of transfusion and postoperative complications. We included 10 studies in our analysis, which we rated according to Downs and Black criteria. With primary knee arthroplasty, there was a reduction in transfusion rate from 22% to 76% and a 48% reduction in transfusion volume (n = 887). With primary hip arthroplasty, there was a reduction from 69% to 73% in transfusion rate and a 31% reduction in transfusion volume (n = 239). There was a significant decrease in length of hospital stay (9.6 v. 13.6 d). Studies of revision arthroplasty reported a 31%-59% reduction in transfusion volume (n = 241). The available evidence demonstrates reduced exposure to allogenic blood with the use of salvage systems. Studies have been underpowered to detect differences in infection rates and other postoperative complications. Future cost analysis is warranted.

Orthopedic surgeon perspectives on appropriate referral of trauma patients to physical therapy (PT).

OBJECTIVES: To evaluate orthopedic surgeon referral of trauma patients to PT. DESIGN: Cross-sectional survey. SETTING: Alberta, Canada. PARTICIPANTS: Orthopedic surgeons and residents. METHODS: A web-based survey was utilized to poll orthopedic surgeons and residents on referral practices. Statistical analysis using Kruskal-Wallis One-Way Analysis of Variance by Ranks; Post hoc analysis using the minimum significant difference method for multiple comparisons and nonparametric correlations using Spearman's rho. RESULTS: The overall response rate was 48 %. Key indications for referral were range of motion deficits, failure to progress, strength and gait training. Of those surveyed, 72.5 and 26.1 % felt that there was either moderate or significant improvement following PT, respectively. Years in practice had a significant effect on survey responses. Residents and surgeons in practice for >20 years viewed PT as being less important in orthopedic trauma (p < 0.05) and were less likely to refer orthopedic trauma patients to PT (p < 0.05). Residents were less likely to view PT in orthopedic trauma as evidence-based (0.05) and more likely to disagree with the statement that formalized PT results in better outcomes than a prescribed home exercise program (p < 0.05). CONCLUSIONS: There are potential differences in the referral practices of orthopedists of varying levels of experience. Although outcome is viewed as positive following PT, it appears that many orthopedists view a prescribed home exercise program as an acceptable equivalent to formalized PT in the setting of orthopedic trauma. Future research should be directed at determining indicators for formalized PT.
