The two-incision total hip arthroplasty (THA) technique offers faster recovery and shorter hospital stays. However, it requires longer operation times and has a higher complication rate than the one-incision method.

Area of Science:

Orthopedic Surgery
Minimally Invasive Surgery

Background:

Evaluating the efficacy of minimally invasive surgery (MIS) total hip arthroplasty (THA).
Focusing on the Mears two-incision technique for THA.

Purpose of the Study:

Compare the one-incision and two-incision THA techniques.
Assess effectiveness, recovery, and complications.

Main Methods:

Retrospective study of 64 patients (2003-2006).
Group I: 34 hips (one-incision).
Group II: 30 hips (two-incision).
Evaluated operation time, blood loss, incision length, ambulation, hospital stay, and complications.

Main Results:

No significant difference in blood loss or clinical outcomes.

The Transition to an Anterior-Based Muscle Sparing Approach Improves Early Postoperative Function but is Associated with a Learning Curve

Published on: September 7, 2022

Two-incision THA showed earlier ambulation and shorter hospital stays.

Longer initial operation time for two-incision, but improved with experience.

Higher rate of intraoperative periprosthetic fracture (13.3%) in the two-incision group.

Conclusions:

Two-incision THA facilitates quicker patient recovery and reduced hospital stays.
Challenges include longer operative times and increased complication rates.
Further refinement needed to optimize the two-incision THA technique.
