Abstract
Rotator cuff pathology is extremely common and can be a significant cause of shoulder pain and functional limitations. Injuries include a spectrum of disease from partial-thickness tears to full-thickness massive tears. Although frequently asymptomatic, partial-thickness rotator cuff tears can become increasingly painful and functionally limiting with cumulative injuries and increasing age. Although many of these can be managed conservatively, a substantial number of partial-thickness tears will progress to requiring surgery, the technique for which is often dictated by the location and thickness of the tear. This chapter will provide a brief overview of the epidemiology and pathoanatomy of partial-thickness tears, followed by a step-by-step review of the clinical decision-making process including patient history, physical exam, imaging, and discussion of surgical techniques and indications, and lastly, a brief overview of clinical outcomes based on tear location and characteristics.

Arthroscopic video of a left shoulder demonstrating a high-grade partial-thickness articular-sided tear of the supraspinatus. Examination of the undersurface of the rotator cuff from within the joint demonstrates a high-grade articular-sided tear of the supraspinatus (0:00). Attention is then turned to the subacromial space. Following debridement and a thorough bursectomy, the bursal surface of the rotator cuff is interrogated and penetrated with an arthroscopic probe (0:12). An 11-blade is introduced through the lateral portal and used to complete the tear. The completed tear is debrided, and the tuberosity is prepared with a bone-cutting shaver (0:45). A single double-loaded suture anchor is placed centrally within the completed tear, approximately 5-mm lateral to the articular margin (1:10). A combination of a tissue penetrator and suture passing device are then used to complete the medial row of the repair (1:23). Two lateral anchors are then subsequently used to complete the double-row transosseous equivalent repair, placed approximately 5 mm from the lateral edge of the tuberosity (2:24) (MP4 151201 kb)
