Abstract
Vitamin D deficiency is highly prevalent in the general population and is associated with various chronic health conditions. In addition to its role in bone mineralization, Vitamin D has various physiological effects that may impact the pathogenesis of shoulder pathologies. Vitamin D deficiency may also affect outcomes after shoulder surgeries, such as rotator cuff repair and total shoulder arthroplasty. Vitamin D plays a role in tissue healing, bone growth, and maintenance of homeostasis in skeletal muscle cells. Vitamin D also has anti-inflammatory effects that are important to rotator cuff health. Vitamin D deficiency is highly prevalent in patients with rotator cuff tears, suggesting its role as a potential risk factor. Vitamin D deficiency has been associated with decreased preoperative shoulder strength as well as increased re-tear rates, postoperative stiffness, and the need for revision surgery in patients who underwent rotator cuff repair. Studies have also demonstrated a potential association between vitamin D deficiency and increased risk of revision after total shoulder arthroplasty. Further research is necessary to elucidate the direct role of vitamin D in the pathogenesis of rotator cuff tears and its impact on clinical outcomes after rotator cuff surgery and total shoulder arthroplasty.

Abstract
Background This study aimed to characterize patient, imaging, and surgical factors associated with re-tear patterns after rotator cuff repair, as well as to identify predictors of type 2 failure in a large patient cohort. Methods A retrospective case-control study was performed at a single urban academic institution. All patients who underwent an arthroscopic rotator cuff repair by 2 fellowship-trained shoulder and elbow surgeons between 2005 and 2022 and were subsequently found to have a symptomatic re-tear on magnetic resonance imaging were included. Patients were characterized as either a type 1 (failure at bone-tendon interface) or type 2 (failure medial to the bone-tendon junction) re-tear based on the Cho classification. Chart review was performed to collect demographic, imaging, and intraoperative surgical factors. Multivariable analysis was performed to determine patient and imaging factors associated with type 2 failure. Results Fifty-seven patients were included in the study. Overall, 33 (57.9%) patients were classified as a Cho 1 re-tear and 24 (42.1%) were classified as Cho 2 re-tear. No differences in preoperative tear characteristics (tear width, tear retraction, and tendon length) or fatty infiltration were found between Cho 1 and Cho 2 re-tears. Bivariate analysis comparing Cho 1 vs. Cho 2 found male sex was associated with a higher incidence of a Cho 2 re-tear (79.2% vs. 20.8%; P = .033). No significant differences in repair construct (single row vs. double row) (P = .816), biceps treatment (P = .552), concomitant subscapularis repair (P = .306), number of medial anchors (P = .533), or number of lateral anchors (P = .776) were noted between re-tear types. After controlling for potential confounding factors, multivariable regression analysis demonstrated that male sex was predictive of developing a Cho 2 re-tear (odds ratio 3.8; 95% confidence interval 1.1-13.3; P = .039). Repair construct was not found to be predictive of re-tear pattern (P = .580). Conclusion Repair construct used during rotator cuff repair does not appear to influence re-tear pattern. Male sex was associated with a higher rate of type 2 failure.

Abstract
Rotator cuff tears are the most common upper extremity condition seen by primary care and orthopaedic surgeons, with a spectrum ranging from tendinopathy to full-thickness tears with arthritic change. Some tears are traumatic, but most rotator cuff problems are degenerative. Not all tears are symptomatic and not all progress, and many patients in whom tears become more extensive do not experience symptom worsening. Hence, a standard algorithm for managing patients is challenging. The pathophysiology of rotator cuff tears is complex and encompasses an interplay between the tendon, bone and muscle. Rotator cuff tears begin as degenerative changes within the tendon, with matrix disorganization and inflammatory changes. Subsequently, tears progress to partial-thickness and then full-thickness tears. Muscle quality, as evidenced by the overall size of the muscle and intramuscular fatty infiltration, also influences symptoms, tear progression and the outcomes of surgery. Treatment depends primarily on symptoms, with non-operative management sufficient for most patients with rotator cuff problems. Modern arthroscopic repair techniques have improved recovery, but outcomes are still limited by a lack of understanding of how to improve tendon to bone healing in many patients.
