This study aims to compare the functional results of patients who underwent two different arthroscopic methods for the management of articular-sided partial-thickness rotator cuff tears (PT-RCTs).

The present study aims to compare the functional results following the repair of PT-RCTs using the conversion versus the trastendon techniques

This is a prospective randomized study carried out at a tertiary trauma center between October 2022 and June 2023. The research ethical Committee authorized this study protocol [(Institutional Review Board (IRB) number: N-383-2023)], and all participants signed an informed consent prior to joining the study. This study included 50 patients with PT-RCTs who underwent arthroscopic repair using either the conversion technique (25 patients) in group A or the transtendon technique (25 patients) in group B. The random assignment of all patients to enter either group was computerized using simple randomization.

The inclusion criteria were:

• Patients suffering symptomatic PT-RCTs exceeding 50% of the tendon thickness, documented by preoperative magnetic resonance imaging (MRI) and confirmed by arthroscopy intraoperative.
• Failure of nonoperative management for at least 3 months.

The exclusion criteria were:

• Prior shoulder surgery.
• Severe concomitant pathologies including glenohumeral arthritis, advanced subscapularis tear, and biceps tendon rupture.
• Associated Bankart lesion.
• Patients with uncontrolled Diabetes mellites.
