Anterolateral mini-incision hip replacement surgery: a modified Watson-Jones approach

Area of Science:

• Orthopedic Surgery
• Minimally Invasive Procedures

Background:

• Traditional hip replacement approaches can lead to complications like abductor weakness and posterior dislocation.
• Previous anterolateral approaches often damaged gluteal muscles and nerves, impacting patient outcomes.
• Minimally invasive techniques aim to reduce surgical trauma and accelerate patient rehabilitation.

Purpose of the Study:

• To describe an innovative mini-incision total hip replacement technique.
• To preserve muscle integrity and the posterior capsule during hip arthroplasty.
• To facilitate faster patient rehabilitation and reduce dislocation risk.

Main Methods:

• A novel mini-incision approach utilizing the intermuscular plane between the gluteus medius and tensor fascia lata.
• Preservation of gluteal muscles and the superior gluteal nerve.
• Maintenance of the posterior capsule integrity.

Main Results:

• The described technique provides adequate surgical exposure for total hip replacement.
• Muscle integrity is preserved, supporting rapid rehabilitation.
• The intact posterior capsule minimizes the risk of posterior dislocation.

Conclusions:

• This mini-incision approach offers a viable alternative to traditional hip replacement methods.
• It effectively addresses complications associated with muscle damage and dislocation.
• The technique supports enhanced patient recovery and satisfaction.
