Leg length and offset in short-stem total hip arthroplasty: is a single offset-implant sufficient to restore the hip rotation centre within a range of 5 mm?

Puntos clave

• Restoring the hip rotation center within 5 mm is crucial in total hip arthroplasty.
• Notably, variations in leg length can impact functional outcomes after surgery.
• Assessment of offset-implants reveals their significance in restoring leg alignment effectively.
• This highlights the need for careful selection of implant offsets in clinical practice.
