Puncture Capsulotomy Technique During Hip Arthroscopy.

Area of Science:

• Orthopedic Surgery
• Arthroscopy
• Hip Biomechanics

Background:

• Traditional hip arthroscopy techniques like interportal and T-capsulotomies can compromise hip stability by transecting the iliofemoral ligament.
• These methods are associated with complications including dislocation, pain, and heterotopic ossification.
• Preserving capsular integrity is crucial for optimal hip joint biomechanics and minimizing iatrogenic injury.

Purpose of the Study:

• To present and evaluate a minimally invasive puncture capsulotomy technique for hip arthroscopy.
• To assess the efficacy of this technique in preserving hip joint biomechanics and reducing complications.
• To compare outcomes with traditional capsulotomy methods.

Main Methods:

• A novel puncture capsulotomy technique involving the creation of four small, quadrilateral-arranged portals.
• The technique avoids transection of the iliofemoral ligament, maintaining capsular integrity.
• Patient positioning, fluid distention, and portal placement under fluoroscopic and arthroscopic guidance are detailed.

Main Results:

• Significant improvements in functional outcome scores (iHOT-33, HOS-ADL, HOS-SSS, mHHS) at a mean follow-up of 30.4 months.
• High rates of achieving minimal clinically important difference (81.0%) and patient acceptable symptom state (62.0%) for iHOT-33 at 2 years.
• Zero occurrences of infection, osteonecrosis, dislocation, instability, or femoral neck fracture.

Conclusions:

• The puncture capsulotomy technique is a safe and effective minimally invasive approach for hip arthroscopy.
• It preserves hip joint biomechanics by avoiding iliofemoral ligament disruption, leading to improved patient outcomes and reduced complication rates.
• This technique offers a preferable alternative to traditional capsulotomies, enhancing joint stability and patient recovery.
