Background: Intratendinous tears of the rotator cuff are rare, and little has been written about them.Purpose: To investigate the prevalence and clinical and radiological outcomes of arthroscopically confirmed intratendinous tearstreated with transtendon suture bridge repair.Study Design: Case series; Level of evidence, 4.Methods: Included in the study were 33 patients (16 male, 17 female; mean age, 53.4 years) with arthroscopically confirmed intratendinoustears treated with transtendon suture bridge repair from March 2006 to July 2012. A history of trauma was found in 10cases (30.3%). The dominant arm was involved in 26 cases (78.8%). The mean follow-up duration was 56 months. Preoperatively,a thorough physical examination was performed; at final follow-up, shoulder range of motion (ROM) in forward flexion, abduction,external rotation (ER) at the side, and internal rotation (IR) at the back was noted, and clinical outcomes (American Shoulder andElbow Surgeons [ASES] score; University of California, Los Angeles [UCLA] score; visual analog scale [VAS] for pain; and SimpleShoulder Test [SST]) were recorded and compared with the preoperative data. Postoperative magnetic resonance imaging (MRI)was performed at 6 months to investigate rotator cuff healing status and repair integrity.Results: The prevalence of arthroscopically confirmed intratendinous tears was 4.7% among all arthroscopically treated partialthicknessrotator cuff tears. Impingement signs were positive in most of the patients (positive Hawkins-Kennedy test result in78.8%, positive Neer sign in 66.7%, and either positive Hawkins-Kennedy test result or Neer sign in 84.8%). At final follow-up,mean ASES, UCLA, VAS, and SST scores improved significantly from a preoperative mean of 51.4, 18.9, 6.0, and 5.4, respectively,to a postoperative mean of 90.6, 32.9, 1.4, and 10.8, respectively (P\.001). According to the UCLA rating scale, outcomeswere excellent in 17, good in 13, and fair in 3 cases. Shoulder ROM in forward flexion, abduction, ER at the side, and IR at theback improved from a preoperative mean of 135, 129, 25, and L2, respectively, to a postoperative mean of 161, 160, 29, andT10, respectively (P \ .001 for all except ER). As per the Sugaya classification, on postoperative MRI, type I healing status wasfound in 10 (30.3%), type II in 18 (54.5%), and type III in 2 (6.1%) cases. None of the patients showed any evidence of retears.Conclusion: Transtendon suture bridge repair yielded satisfactory clinical and radiological outcomes in patients with intratendinousrotator cuff tears.
