Objective: Rotator interval lesion (RIL) is a distinct rotator cuff (RC) injury patern consisting of subscapularis and supraspinatus tear with biceps problem. This pathology is an underdiagnosed RC entity and not studied in-depth. Aim of this study is to report the functional and radiological results of RIL surgeries performed. Methods: Surgeries performed in a single center, in a 7-yearperiod were retrospectively reviewed. Sixteen cases (n=16) who underwent arthroscopic RC repair including subscapularis with biceps tenodesis or tenotomy were called for an up-to-date assessment. Fourteen shoulders of 13 patients (3 females, 10 males) were included. Constant, disabilities of the arm shoulder and hand (DASH), standardized shoulder assessment form (ASES) scores, and RC thickness measurements with magnetic resonance imaging (MRI) were recorded. Preoperative and postoperative results were compared. Results: The average age of the patients were 60.6 (47-74), and follow-up period was 3.2±1.9 years. Average preoperative Constant, DASH and ASES scores were 44.43±15.4, 22.11±17.21 and 51.37±27.6, respectively. Postoperative values improved to 90.45±6.44, 6±13.68 and 95.82±7.82, respectively (p<0.05). Average subscapularis and supraspinatus thicknesses measured with MRI were 3.85±0.87 and 4.60±0.65 mm respectively. MRI revealed subscapular tendinitis in 1 patient. Re-tear was not observed in any patients. Conclusion: Arthroscopic subscapularis and supraspinatus repair with biceps tenodesis or tenotomy is an effective treatment method in RIL. No retar was observed with MRI. Clinical results are similar with other RC pathologies.
