Table 1

Outcomes of bursal-sided rotator cuff tears secondary to SC.

Authors, year	Site of RCT	Thickness/size of RCT	Open versus arthroscopic	Procedure	Follow-up (months)	Outcome
Milgram and Hadesman, 1988 [9]	Unspecified	Unspecified	Open (deltopectoral)	LBR, RCE, acromioplasty, DCE, and SAD	6	Recovered shoulder function over a two-month period
Ko et al., 1995 [12]	Supraspinatus, infraspinatus	4 full-thickness tears and multiple partial-thickness tears which were slit-like and perpendicular to axis of tendons	Open (Saber)	LBR, RCE with direct sutures, acromioplasty, and partial synovectomy	24	No symptoms, normal ROM, and radiographs without recurrence
Ogawa et al., 1999 [3]	Supraspinatus, bilateral	Bursal-sided, partial-thickness tear, 5 mm in depth	Arthroscopic	LBR, RCR, acromioplasty, and bursectomy	48	Only mild pain when engaging in sports and no radiographs reported
Horii et al., 2001 [11],; case 1	Unspecified	Partial-thickness, longitudinal tear	Unspecified	LBR, RCR with side-to-side suture, acromioplasty, and bursectomy	2	Returned to work without pain
Horii et al., 2001 [11],; case 2	Unspecified	Partial-thickness, longitudinal tear 1 cm in length	Unspecified	LBR, RCR with side-to-side suture, acromioplasty, and bursectomy	12	Little pain and slight limitation in passive abduction at 130°
Huang et al., 2004 [2]	Supraspinatus	Full-thickness tear about 1 cm at the critical zone	Unspecified	LBR, RCR, and acromioplasty	12	Painless; AROM FF 170°, ER 30°, and IR T12.; PROM FF 175°, ER 40°, and IR T10
