Randomized Controlled Trial
Prewarming operating rooms for prevention of intraoperative hypothermia during total knee and hip arthroplasties.
Prewarming operating rooms has been shown to limit hypothermia in pediatric surgical patients but may be associated with extreme discomfort for surgeons. We examined the effect of prewarming operating rooms on core temperatures during knee and hip arthroplasties. Sixty-six patients were randomized to the prewarmed group at 24 °C or control group at 17 °C. ⋯ By the start of surgery, the difference was 36.01 °C prewarmed vs 35.83 °C control, P = .038. There was no significant difference in the last recorded mean temperatures between groups: 36.35°C (prewarmed) vs 36.16 °C (control). A prewarmed operating room for adults undergoing knee or hip arthroplasty had minimal effect on preventing intraoperative hypothermia.

Randomized Controlled Trial
Anterolateral minimally invasive total hip arthroplasty: a prospective randomized controlled study with a follow-up of 1 year.
Anterolateral minimally invasive hip surgery (ALMIS) is a challenging procedure that is thought to offer a more expedient and a better functional outcome. Seventy-nine patients receiving primary hip arthroplasty were randomized. Röttinger ALMIS technique was used for 42 patients, whereas 41 received the standard lateral transgluteal Hardinge approach. ⋯ Computed tomographic analysis revealed no significant difference in implant position, heterotopic ossification, and loosening. Röttinger ALMIS is a valid approach for hip arthroplasty. However, it offers no advantages at 1 year.
