It is of great significance to explore the clinical efficacy of arthroscopic treatment of glenoid incision cysts and associated injuries under shoulder arthroscopy. This article retrospectively analyzed 11 patients with glenoid incisure cysts admitted from August 2016 to February 2022. Among them, 7 had symptoms of suprascapular nerve compression, and 5 had SLAP injury. The preoperative shoulder MRI confirmed the diagnosis of glenoid incisure cysts in the shoulder joint. All cysts were removed under arthroscopy and combined shoulder joint lesions such as SLAP injury and rotator cuff injury were treated. This paper evaluates shoulder joint function through VAS score, ASES score, Constant score, and MRI examination to assess whether the cyst relapses. The study found that all 11 patients were followed up for an average of 32 months. The VAS score, ASES score, and Constant score of the patients increased from preoperative (5 ± 1), (8 ± 3.2), and (61 ± 8.6) to (1 ± 0.5), (11 ± 1.2), and (83 ± 5.4), respectively. The differences between preoperative and postoperative were statistically significant (P<0.05). There were no postoperative complications, and the shoulder joint activity returned to normal. The abductor and supinator muscle strength of the shoulder joint returned to level V. MRI reexamination showed no recurrence of cysts. Research suggests that arthroscopic surgery on the shoulder has significant advantages and can achieve good early therapeutic effects for cysts of the glenoid notch, especially those with pelvic lip injury or rotator cuff injury.
