Contrast-Enhanced Ultrasound Reveals Superior Gluteus Medius Muscle Vitality After Total Hip Arthroplasty in a Minimally Invasive Anterolateral Versus Lateral Surgical Approach.

Objective: Total hip arthroplasty (THA) is essential for treating severe osteoarthritis. With various surgical approaches available, there has been a shift toward techniques that offer quicker recovery and fewer complications. In this study, contrast-enhanced ultrasound was used to evaluate the impact of the minimally invasive anterolateral versus conventional lateral approach in THA on the gluteus medius muscle, focusing on muscle vitality and functional outcomes.
