Total Hip Replacement (THA) is one of the most successful and cost-effective operations. Despite its benefits, marked ethnic differences in the utilization of THA are well documented. However, very little has been published on the influence of ethnicity on outcome. We investigate whether the outcome-in terms of reoperation within 2 years or revision up to 14 years after the primary operation-varies depending on ethnic background. ⋯ We did not find any certain differences in reoperation within 2 years, or revision within 14 years, between patients born in Sweden and immigrants. Further studies are needed to determine whether our observations are biased by the attitude of health providers regarding performance of these procedures, or by a reluctance of certain patient groups to seek medical attention should any complications requiring reoperation or revision occur.

Randomized Controlled Trial Comparative Study
Evaluation of a single preoperative dose of etoricoxib for postoperative pain relief in therapeutic knee arthroscopy: a randomized trial.
BACKGROUND AND PURPOSE Analgesics can have undesirable effects. We assessed whether a single preoperative dose of 120 mg etoricoxib reduces the need for additional opioids after therapeutic arthroscopic knee surgery. METHODS A double-blind, placebo-controlled study was performed at a single center. 66 patients scheduled to undergo elective therapeutic knee arthroscopy were included. They were randomly selected to be given either 120 mg of etoricoxib (n = 33) or placebo (n = 33) 1 hour before induction of general anesthesia. A patient-controlled analgesia device was used postoperatively. We recorded total postoperative morphine consumption over 24 h, degree of pain as assessed with a visual analog scale, degree of satisfaction, and occurrence of adverse effects. RESULTS Mean total morphine consumption during the first 24 h was 24 (9-60) mg in the placebo group and 9 (0-34) mg in the etoricoxib group. In the etoricoxib group, pain intensity levels at rest were reduced and patient satisfaction with the analgesia provided was higher during the first postoperative day. There was no difference in the incidence of typical adverse effects of opioids in the 2 groups. ⋯ Etoricoxib is a suitable premedication to use before therapeutic arthroscopic knee surgery, as it reduced patients' morphine requirements.

Randomized Controlled Trial Comparative Study
Minimally invasive surgery did not improve outcome compared to conventional surgery following unicompartmental knee arthroplasty using local infiltration analgesia: a randomized controlled trial with 40 patients.
There has recently been interest in the advantages of minimally invasive surgery (MIS) over conventional surgery, and on local infiltration analgesia (LIA) during knee arthroplasty. In this randomized controlled trial, we investigated whether MIS would result in earlier home-readiness and reduced postoperative pain compared to conventional unicompartmental knee arthroplasty (UKA) where both groups received LIA. ⋯ Minimally invasive surgery did not improve outcome after unicompartmental knee arthroplasty compared to conventional surgery, when both groups received local infiltration analgesia. The surgical approach (MIS or conventional surgery) should be selected according to the surgeon's preferences and local hospital policies. ClinicalTrials.gov. (Identifier NCT00991445).

Revision total hip arthroplasty (THA) due to recurrent dislocations is associated with a high risk of persistent instability. We hypothesized that the use of dual-mobility cups would reduce the risk of re-revision due to dislocation after revision THA. ⋯ The risk of re-revision due to dislocation after insertion of dual-mobility cups during revision THA performed for recurrent dislocations appears to be low in the short term. Since most dislocations occur early after revision THA, we believe that this device adequately addresses the problem of recurrent instability. Younger age and prior hip revision surgery are risk factors for further revision surgery. However, problems such as potentially increased liner wear and subsequent aseptic loosening may be associated with the use of such devices in the long term.

Comparative Study
Is mortality after hip fracture associated with surgical delay or admission during weekends and public holidays? A retrospective study of 38,020 patients.
Hip fractures are associated with high mortality, but the cause of this is still not entirely clear. We investigated the effect of surgical delay, weekends, holidays, and time of day admission on mortality in hip fracture patients. ⋯ Minimizing surgical delay is the most important factor in reducing mortality in hip fracture patients.
