About

This study involves comparing the outcomes after using the Direct Anterior Approach (DAA) and the Supercapsular Percutaneously Assisted Total Hip (SuperPATH) approach. These are two approaches to hip replacement that both replace hips without cutting any muscles. DAA approach has been used for many years, but it has a high learning curve and can be difficult for doctors to use, it is however linked with fewer complications when performed by an experienced doctor. SuperPATH is a newer technique which has been shown in studies to be adopted with less complications even during the learning phase. It also shows cost-saving results, showing a reduced length of stay for patients and better 30-day readmission rates. There is pressure on surgeons, from both patients and administration to use techniques that spare tissue, offer early functionality without compromising long-term outcomes. The SuperPATH can meet this benchmark but uptake has been slow, the investigators believe that it is due to the learning curve shown by this approach. The senior surgeon at The Ottawa Hospital is experienced in both techniques, using a trial the investigators can compare the two techniques and help encourage surgeons to change to a procedure that has demonstrated a low complication profile.
