Background

Gluteus medius tears, particularly in the setting of THA, can contribute to persistent lateral hip pain and compromised function. This study examines short-term results of GM repair during THA using modern suture anchor techniques.

Methods

Patients undergoing primary THA with concomitant gluteus medius repair via either direct anterior or posterior approach were evaluated at a minimum of 24 months using validated PROMs.

Key Findings

• Patients demonstrated significant improvements in pain and function postoperatively.
• No notable differences were observed between anterior and posterior surgical approaches.
• The use of modern suture anchor fixation provided stable repair with favorable outcomes.

Conclusions

Addressing GM tears during THA using contemporary repair techniques is associated with reduced pain and improved function in the short term, regardless of surgical approach.

What Does This Mean for Providers?

• Consider routine intraoperative evaluation of the GM tendon in THA patients, particularly those with preoperative lateral hip pain or abductor weakness.
• Modern suture anchor repair techniques are effective when performed alongside THA and should be included in the surgeon's armamentarium.
• Surgical approach (anterior vs. posterior) may not significantly influence GM repair outcomes, allowing flexibility based on surgeon expertise and case context.
