The study aims to discuss the challenges associated with breakage or failure of the abductor mechanism after total hip arthroplasty, which can lead to gait issues, instability, and the need for revision surgery. Sutures play a crucial role in preventing these failures, with two main types: transosseous and tendon sutures. Transosseous suturing involves using non-absorbable threads anchored in the bone, while tendon suturing uses absorbable threads for layered closure.

Both techniques are commonly used, but there is a lack of evidence to determine which is more beneficial for patients. Current studies are limited and often focus on cases requiring revision surgery due to complications, with transosseous sutures generally being the preferred method.

A meta-analysis indicated that transosseous repair may result in lower dislocation rates and less postoperative pain, but further randomized clinical trials with long-term follow-up are necessary for definitive conclusions. The text proposes a prospective study to compare transosseous suturing with the common absorbable tendon suturing in primary hip surgeries.
