Abstract

Total Hip Arthroplasty (THA) is considered the most successful treatment for advanced hip osteoarthritis. Different surgical approaches for THA are available and they have shown excellent outcomes in the long-term follow-ups. However, few studies have analyzed the functional outcomes in the first days after a THA surgery. The purpose of this study was to compare the early functional outcomes between two different surgical techniques: a minimally invasive direct anterior approach (mini-DAA) and a postero-lateral approach (PL). Twelve patients for each group were analyzed. Pre- and postoperative (3, 10, 30 and 90 days after surgery) Patient-Reported Outcome Measures (PROMs) were administered: HOOS, HHS, VAS and SF-12-v2 scores. Moreover, comparison between surgical operation time and blood loss were examined. PROMs showed a significant improvement in the SF-12-v2 in the mini-DAA group compared to the PL group at 3 days after surgery: this difference was maintained also after 10 and 30 days. In addition, HOOS and HHS were significantly ameliorated in the mini-DAA group starting 10 days from surgery. In both groups, a physiological pain reduction was observed in the first days after surgery; comparing it to the pre-surgical VAS values, we found a significant improvement in the scores for the mini-DAA group after 30 days. Moreover, we demonstrated a significant reduction in blood loss for the mini-DAA group. Surgical operation times were similar in the two groups; however, the duration of the mini-DAA procedure was shorter compared with the known literature. In this preliminary study, we demonstrated that the minimally invasive direct anterior approach for THA may lead to benefits in the early postoperative time, as it allows for an improvement in functional outcomes, a reduction of postoperative pain, a reduction of hospitalization time and consequent reduction of postoperative complications; therefore, this surgical approach may consent an early return to work and daily activities.
