Work satisfaction and retirement plans of orthopaedic surgeons 50 years of age and older.
Retirement age and practice patterns before retirement are important for making accurate workforce predictions for orthopaedic surgeons. A survey of orthopaedic surgeons 50 years of age and older therefore was conducted by the American Academy of Orthopaedic Surgeons in cooperation with the Association of American Medical Colleges Center for Workforce Studies. The survey focused on three questions: (1) At what age do orthopaedic surgeons retire? (2) Do they stop working abruptly or do they work part time before retirement? (3) What are the major factors that determine when an orthopaedic surgeon retires? According to the survey, the median retirement age for orthopaedic surgeons was 65 years. Nineteen percent of orthopaedic surgeons worked part time before retirement. Decreasing reimbursement and increasing malpractice costs were consistently cited as factors that strongly influenced retirement plans. Career satisfaction was high and was the strongest factor that kept the respondents in the workforce. The option to work part time would have the most impact on keeping orthopaedic surgeons working past the age of 65 years. ⋯ Level IV Economic and Decision Analyses.

Randomized Controlled Trial Multicenter StudyRandomized study of aprotinin effect on transfusions and blood loss in primary THA.
A projected increase in total hip arthroplasties, shortfalls in blood availability, and awareness of complications of transfusion make blood management in orthopaedic surgery important. In a multicenter, randomized, double-blind, placebo-controlled study, we hypothesized use of aprotinin would reduce blood transfusions (any and allogeneic) and blood loss in total hip arthroplasty. Using an intent-to-treat approach, we recruited 393 patients stratified by preoperative autologous blood donation or none and then randomized them to receive aprotinin (176 patients receiving a 10,000 kallikrein inhibitor units [KIU] test dose, 2 million KIU load, 0.5 million KIU per hour) or placebo (177 patients). ⋯ Aprotinin reduced the total number of any blood units and the number of allogeneic blood units transfused relative to placebo (48 versus 109 units and 30 versus 72 units, respectively). Serious complications were similar in the two groups (placebo, 11%; aprotinin, 10%). Our data suggest full-dose aprotinin is safe and effective in decreasing blood transfusion in total hip arthroplasty.

Factors affecting results of ulnar shortening for ulnar impaction syndrome.
Although ulnar shortening osteotomy is the most frequently performed operation for ulnar impaction syndrome, little attention has been given to detect certain preoperative factors affecting clinical outcomes of this procedure. We asked whether preoperative factors influenced the postoperative score of ulnar shortening osteotomy combined with arthroscopic debridement of the triangular fibrocartilage complex. We retrospectively reviewed 51 patients (53 wrists) with ulnar impaction syndrome treated with this procedure. ⋯ The clinical score ranged from 40 to 100 points (mean, 84.5 points). A long duration of symptoms and workers' compensation predicted worse clinical scores. We recommend considering these two factors when deciding whether to perform this procedure.

Clinical TrialPain and depression influence outcome 5 years after knee replacement surgery.
We previously reported preoperative depression, anxiety, and pain were associated with greater pain, more utilization of healthcare resources, and worse outcome 1 year after total knee arthroplasty. We asked whether these outcomes persisted over time and whether patients with unexplained heightened pain early after surgery were ultimately satisfied. We prospectively followed and evaluated 83 patients (109 TKAs) 5 years postoperative. The mean age was 66 years; 55% were women. Preoperative pain and depression predicted lower Knee Society score mostly related to lower function subscores. Although anxiety was associated with greater pain, worse function, and more use of resources in the first year after surgery, anxiety did not affect ultimate outcome. Most patients required a full year to recover from surgery but with negligible improvements in most parameters afterward. However, patients with heightened, unexplained pain at 1 year had progressive improvement in pain over several years. By 5 years, nearly all of these patients were satisfied. Therefore, assuming good range of motion and well-aligned implants, most patients with pain 1 year after surgery can be reassured pain ultimately improves. Depression drives long-term outcomes; the Knee Society score is influenced by psychologic variables and does not solely reflect issues related to the knee. Expansion of this tool to include measures sensitive to psychologic and other health factors should be considered. ⋯ Level I, prognostic study.
