A Randomized, Prospective Study of Three MIS Surgical Approaches in TH

Purported advantages of total hip arthroplasty (THA) performed with minimally invasive surgical (MIS) approaches are less muscle damage and faster recovery. Currently, there are little data that objectively and scientifically evaluate these claims. Comparative gait analysis was performed on patients who underwent THA using 1 of 3 different MIS approaches. All 3 surgical approach groups demonstrated overall improvements in measured gait parameters at the 6-week postoperative analysis. The results of this gait analysis fail to demonstrate any significant advantage of the 2-incision approach over the posterior approach in gait parameters and early functional recovery. Furthermore, the anterolateral approach demonstrates a gait pattern consistent with abductor muscle injury in the early recovery period, despite the use of a minimally invasive approach.
