Background: Ongoing controversy surrounds the best treatment modality for partial-thickness rotator cuff tears. Purpose: To investigate the effects of atelocollagen injection in patients with small, symptomatic, intratendinous rotator cuff tears. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: From January 2014 to December 2017, 94 patients who had small, symptomatic, intratendinous rotator cuff tears were enrolled and randomly allocated to 1 of 3 groups: intratendinous injection with 0.5 mL of type I atelocollagen (group 1, n = 32), intratendinous injection with 1 mL of type I atelocollagen (group 2, n = 30), and no injection of type I atelocollagen (group 3, n = 32). American Shoulder and Elbow Surgeons score, Constant Shoulder Score, visual analog scale pain score, and range of motion were evaluated before injection; at 3, 6, and 12 months after injection; and at final follow-up. Magnetic resonance imaging (MRI) was performed at least 6 months after injection to evaluate rotator cuff integrity. Results: Demographic data did not differ significantly among the 3 groups before injection ( P > .05). The mean follow-up period was 24.7 months. The functional and pain scores in groups 1 and 2 were significantly improved at final follow-up ( P < .05). No significant improvement was seen in functional or pain scores at final follow-up in group 3 ( P > .05). Groups 1 and 2 had significantly better functional scores compared with group 3 at final follow-up ( P < .05). The proportion of patients with a decrease in size of the torn tendon on follow-up MRI at least 6 months after atelocollagen injection was significantly higher in group 1 (28.1%; P = .02) and group 2 (36.7%; P = .003) compared with group 3 (6.3%). Conclusion: Atelocollagen injection can improve the functional outcome and integrity of the tendon in intratendinous rotator cuff tears.

Background: High-grade partial-thickness rotator cuff tears (hPTRCTs) are frequently encountered in the shoulder. However, little information is available on the prevalence or timing of tear progression. Purpose/Hypothesis: The purpose was to prospectively evaluate the structural progression of hPTRCTs with a minimum follow-up of 1 year using magnetic resonance imaging (MRI). The hypothesis was that a substantial portion of hPTRCT patients would experience tear progression or evolution to a full-thickness rotator cuff tear. Study Design: Case series; Level of evidence, 4. Methods: Between May 2010 and December 2015, 362 patients were diagnosed with hPTRCT (tear involvement >50% of the mediolateral length of the footprint) of the supraspinatus and were treated nonoperatively. Among these patients, 81 underwent follow-up MRI at least 1 year after initial presentation, and these patients were included in the final analysis. Initial and follow-up MRIs were used to determine whether tears had improved, had not changed, or had progressed. A change in tear involvement of >20% was defined as a significant change. Patients were categorized as follows: (1) a decrease in tear involvement of >20% (improved), (2) an increase or decrease of ≤20% (no change), or (3) an increase in tear involvement of >20% (progressed). Demographic data and morphologic data were analyzed to identify variables related to tear progression. Among them, severity of tendinosis was graded using MRIs: grade 1 (mild tendinosis), mild focal increase in tendon signal; grade 2 (moderate tendinosis), moderate focal increase in tendon signal; and grade 3 (marked tendinosis), marked generalized increase in tendon signal. Results: At initial diagnosis, 23 were articular-side (28%) and 58 were bursal-side (72%) hPTRCTs. The study cohort was composed of 51 women and 30 men, and the mean patient age was 62.3 years (range, 41-77 years). Follow-up MRI was performed at a mean 19.9 ± 10.9 months (range, 12-52 months). A significant change in tear involvement was observed at follow-up. In 13 patients (16%, 2 articular-side and 11 bursal-side tears), tears were classified as progressed (the progressed group); in 48 patients (59%), tears exhibited no change (the unchanged group); and in 20 patients (25%, 9 articular-side and 11 bursal-side tears), tears were improved (the improved group). Univariate analysis showed initial tendinosis grade was significantly different in the 3 groups (grade 1, 2, and 3: 5, 4, and 4 in progressed; 36, 11, and 1 in unchanged; 10, 8, and 2 in improved group, respectively, P = .007). Conclusion: Although progression of hPTRCT in the long term is uncertain, after 1-year follow-up with MRI, tears progressed in 16% of the tears in this study. Furthermore, some tears were healed or reduced in size, which indicates that decisions to undertake surgical repair at time of presentation may be excessive.

Background: Partial-thickness articular-sided rotator cuff tears are a frequent source of shoulder pain. Despite conservative measures, some patients continue to be symptomatic and require surgical management. However, there is some controversy as to which surgical approach results in the best outcomes for grade 3 tears. Hypothesis/Purpose: The purpose of this study was to evaluate repair integrity and the clinical results of patients treated with transtendinous repair of high-grade partial-thickness articular-sided rotator cuff tears. Our hypothesis was that transtendinous repairs would result in reliable healing and acceptable functional outcomes. Study Design: Case series; Level of evidence, 4. Methods: Twenty patients with a minimum follow-up of 2 years were included in the study. All patients underwent arthroscopic repair of high-grade partial-thickness rotator cuff tears utilizing a transtendinous technique by a single surgeon. At latest follow-up, the repair integrity was evaluated using ultrasound imaging, and functional scores were calculated. Results: Ultrasound evaluation demonstrated that 18 of 20 patients had complete healing with a normal-appearing rotator cuff. Two patients had a minor residual partial tear. Sixteen of 20 patients had no pain on visual analog scale. Four patients complained of mild intermittent residual pain. All patients were rated as “excellent” by both the University of California at Los Angeles Shoulder Score and the Simple Shoulder Test. Conclusion: The transtendon technique for the repair of articular-sided high-grade partial rotator cuff tears results in reliable tendon healing and excellent functional outcomes.

Background: Optimal patient selection is key to the success of nonoperative treatment for rotator cuff tears. Purpose: To assess the predictors of pain and functional outcomes in a longitudinal cohort of patients undergoing nonoperative treatment. Study Design: Cohort study; Level of evidence, 2. Methods: A multicenter cohort of patients with rotator cuff tears undergoing nonoperative treatment was recruited from March 2011 to February 2015. Patients completed a detailed health questionnaire, completed standardized shoulder questionnaires including the Shoulder Pain and Disability Index (SPADI), and underwent magnetic resonance imaging. In addition to baseline assessments, patients received follow-up questionnaires at 3, 6, 12, and 18 months. Longitudinal mixed models were used to test predictors of the SPADI score, and interactions with time were assessed. Results: In our cohort of 70 patients, being married as compared with being single/divorced/widowed ( P = .02), a shorter duration of symptoms ( P = .02), daily shoulder use at work that included light or no manual labor versus moderate or heavy manual labor ( P = .04), alcohol use of 1 to 2 times per week or more as compared with 2 to 3 times per month or less ( P = .007), and absence of fatty infiltration ( P = .0009) were significantly associated with decreased SPADI scores (improved shoulder pain and disability) over time. When interactions with time were assessed, having a college level of education or higher compared with less than a college education showed a differential effect over time, with those with a college level of education or more having lower SPADI scores ( P = .004). Partial-thickness tear versus full-thickness tear also had an interaction with follow-up duration, such that those with a partial-thickness tear had lower SPADI scores ( P = .0002). Conclusion: Longitudinal predictors of better outcomes of the nonoperative treatment of rotator cuff tears included being married, having at least a college education, shorter duration of symptoms, light or manual labor in daily work, alcohol use of 1 to 2 times per week or more, partial-thickness tear, and absence of fatty infiltration of the rotator cuff. Our results suggest that nonoperative treatment should be performed early for optimal outcomes. These data can be used to select optimal candidates for the nonoperative treatment of rotator cuff tears and to assist with patient education and expectations before treatment.
