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.
