To compare the functional outcomes of traumatic and non-traumatic rotator cuff tears after arthroscopic repair.
Eighty-seven patients with rotator cuff tears following arthroscopic treatment were divided into traumatic and non-traumatic tear groups. Postoperative muscle strength and outcomes using the modified University of California, Los Angeles score were evaluated. Sex, age, affected limb and dominant limb were correlated between groups. Muscle strength of the repaired and unaffected shoulders was compared. Rotator cuff injury size was measured.
Of the 87 patients who underwent rotator cuff repairs, 35 had traumatic tears and 52 had non-traumatic tears. In patients with non-traumatic tears, the average age was 59 years, 74.5% were female, 96.1% were right-hand dominant and 92.3% had their dominant shoulder affected. Patients with traumatic tears were 59.5 years old on average, 51.4% were female, 91.4% were right-hand dominant and 88.5% had their dominant shoulder affected. No difference existed in the mean modified University of California, Los Angeles score between patients with traumatic tears (33.7) compared with those with non-traumatic tears (32.8). No strength differences were observed between groups: The strength difference between the non-affected and affected sides was 1.21 kg in the non-traumatic group and 1.39 kg in the traumatic group ( = 0.576), while the strength ratio between the non-affected/affected sides was 0.805 in the non-traumatic group and 0.729 in the traumatic group ( = 0.224).
The functional results of traumatic rotator cuff repairs are similar to non-traumatic tears. Both outcomes are satisfactory.
比较关节镜修复术后创伤性和非创伤性肩袖撕裂的功能结果。
87例接受关节镜治疗的肩袖撕裂患者被分为创伤性撕裂组和非创伤性撕裂组。使用改良的加州大学洛杉矶分校评分评估术后肌肉力量和结果。比较两组之间的性别、年龄、患侧肢体和优势肢体。比较修复侧和未受影响侧肩部的肌肉力量。测量肩袖损伤大小。
在87例行肩袖修复术的患者中，35例为创伤性撕裂，52例为非创伤性撕裂。非创伤性撕裂患者的平均年龄为59岁，74.5%为女性，96.1%为右利手，92.3%的优势肩受累。创伤性撕裂患者的平均年龄为59.5岁，51.4%为女性，91.4%为右利手，88.5%的优势肩受累。创伤性撕裂患者（33.7分）与非创伤性撕裂患者（32.8分）的平均改良加州大学洛杉矶分校评分无差异。两组之间未观察到力量差异：非创伤性组未受影响侧与受影响侧的力量差异为1.21kg，创伤性组为1.39kg（P = 0.576），而非创伤性组未受影响侧/受影响侧的力量比值为0.805，创伤性组为0.729（P = 0.224）。
创伤性肩袖修复的功能结果与非创伤性撕裂相似。两种结果均令人满意。
