Background and AimSeveral patient-related factors have been identified which are responsible for the development of rotator cuff tears. The purpose of the study was to assess various parameters which can be risk factors for the development of supraspinatus tendon tear.MethodsA total of 100 patients with symptomatic rotator cuff tear, aged > 18 years, of either gender, presenting to the outpatient department were included in this cross-sectional study. Magnetic resonance imaging was done and based on its results; patients were identified for the type of tear. Demographic, clinical, and biochemical factors affecting the tears were assessed using logistic regression analysis.ResultsFactors such as age, gender, pain radiation, night pain, and analgesic intake had significant association with supraspinatus tendon tears.Conclusion“Pain radiation” and “Analgesic intake” were two new parameters found associated with the supraspinatus tendon tears. New parameters that have been assessed as risk factors will help in better understanding of supraspinatus tendon tears.  相似文献

PurposeThis study aimed to evaluate the effects of not using a drain or placing a drain in the glenohumeral (GH) or subacromial (SA) joint spaces on fluid retention and pain in the early postoperative period and late clinical outcomes.MethodsPatients who underwent arthroscopic rotator cuff repair between 2018 and 2020 were included in the study. Before the operation, demographic data, range of motion (ROM), visual analog scale (VAS) scores, Constant–Murley scores has documented. Deltoid muscle diameter (DMD) were measured. The total amount of irrigation used during the surgery and the operation duration were recorded, and the active amount of fluid coming from the drain in patients with a drain was recorded. The first postoperative DMD measure was made in the operating room and accepted as day 0. DMD measurements repeated postoperative first and second day. VAS assessments were performed on the postoperative first and second days. At the outpatient clinic, these measurements were repeated on the first and second weeks after discharge. Functional evaluations were made with ROM and Constant–Murley scores at the final follow-up examination.ResultsThere was no difference in the amount of drainage between the two groups in which a drain was used. When the three groups were compared among themselves regarding preoperative and postoperative VAS scores, Constant–Murley scores, and DMD, no significant difference was found.ConclusionsWe do not recommend the routine use of drains after arthroscopic rotator cuff surgery in terms of cost-effectiveness.Level of evidenceLevel II: Prospective Cohort Study.  相似文献
