Abstract:
Background Hip arthroscopic labral repair using suture anchors carries a relatively high risk of cartilage penetration. While computer navigation technology has the potential to enhance surgical precision and safety, reports on its application in hip arthroscopic labral suturing remain scarce. Objective To explore the clinical advantages of intelligent planning and navigation technology in assisting suture anchor placement during hip arthroscopy for labral repair, and evaluate its safety and accuracy. Methods In August 2025, a 28-year-old male patient with cam-type femoroacetabular impingement (FAI) accompanied by a labral tear (LT) and an acetabular cyst was admitted to the Department of Sports Medicine of the Fourth Medical Center of PLA General Hospital. A self-developed intelligent planning and navigation system was employed for preoperative three-dimensional planning and intraoperative real-time guidance. Postoperatively, CT was used to evaluate the position of the suture anchors, with "no anchor penetration into the subchondral bone of the joint or the pelvic side" adopted as the safety evaluation criterion, and "the consistency between the actual insertion distance and angle of the anchors and the preoperative plan" used as the accuracy evaluation criterion. Results The precise placement of the suture anchor and labral repair was successfully completed, effectively avoiding the intraosseous cyst within the acetabulum. A total of 4 anchor screws were placed, all within the safe angle range planned preoperatively. The average actual placement angle was (39.32±8.49)°. The average distance from the anchor insertion point to the subchondral bone of the joint (2.58±0.50) mm was close to the preoperative planning (average 2.05±0.14) mm. Conclusion Arthroscopic labral repair assisted by intelligent planning and navigation technology is safe and reliable especially in high-risk areas such as the anterior acetabular rim, which helps reduce the risk of perforation and has high clinical promotion value and patient benefit prospects.
