[Minimally invasive posterior approach in total hip arthroplasty. Prospective randomised trial].

Background: Our working hypothesis was that minimally invasive surgery was superior to conventional surgery for total hip arthroplasty procedure. We compared THR results in the minimally invasive posterior approach with THR results in the conventional posterior approach.

Methods: Prospective, randomised trial.

Minimally invasive subvastus approach: improving the results of total knee arthroplasty: a prospective, randomized trial.

Background: Minimally invasive knee arthroplasty seeks to diminish the problems of traditional extensile exposures aiming for more rapid rehabilitation of patients after surgery.

Questions/purposes: To determine if the subvastus approach results in less perioperative pain and blood loss, shorter hospital stay, and improved function at both early and long-term followup.

Methods: One hundred patients were enrolled in a prospective, randomized trial.
