RÉSUMÉ
Objective To evaluate the short-term clinical effect of arthroscopic repair of rotator cuff injury with all-suture anchor using a prospective and single-cohort clinical trial.Methods Twenty-five patients with rotator cuff injuries(1.5 cm<tear size<6 cm)and admitted to the Department of Sports Medicine and Ambulatory Surgery Centre of Jiangsu Provincial Subei People's Hospital between July and September 2022 were used as the study subjects.Two cases were excluded for not meeting the in-clusion criteria,while another one was withdrawn halfway due to inconvenience of follow-up.Finally,22 patients were included in the study,consisting of 8 males and 14 females,with the average age of 59.1±10.9 years and rotator cuff tear size of 3.2±1.2 cm of 10 left and 12 right shoulders.Be-fore as well as 3 and 6 months after operation,all patients were evaluated using the pain visual ana-logue scale(VAS),the American Shoulder and Elbow Surgeons(ASES)score,Constant-Murley Shoul-der Functional(Constant)Score,Simple Shoulder Test(SST),bilateral shoulder abduction muscle strength ratio(affected/healthy),and mobility of the affected shoulder joint.Six months after operation,the healing of rotator cuff and the formation of cyst around the all-suture anchor were evaluated by us-ing the magnetic resonance imaging(MRI).According to whether there was cysts around the all-suture anchor,the patients were divided into the cyst group and the cyst-free group.Their age,sex,the side affected,trauma history,course time,tear size and operation time of the two groups were com-pared and analyzed to find the correlated factors.The average VAS,ASES and Constant scores,and the range of motion of the affected shoulder joint and the healing grade of rotator cuff were compared between the two groups 6 months after operation.Results Twenty-two patients were granted 6.2±0.3 months of follow-up after surgery.Three and six months after the operation,their average VAS scores(1.3±1.2 and 0.7±0.4),ASES scores(79.7±12.3 and 88.9±6.5),Constant scores(65.4±12.4 and 73.7±9.6),SST scores(7.6±0.2 and 10.5±0.2)and bilateral shoulder abductor muscle strength ratio(affected side/healthy side)(71.3±9.6 and 90.3±5.9)were significantly higher than the values before the opration(4.2±1.1,51.5±11.2,46.2±12.8,3.5±0.3 and 21.9±15.8),respec-tively(P<0.05).There were also significant differences in the range of motion of shoulder joint 3 months and 6 months after surgery(P<0.05).Postoperative MRI revealed 1 patient with rotator cuff re-tear.There was significant difference in age between the cyst group and the cyst free group(P<0.05).However,there was no significant difference in VAS score,ASES score,Constant score,range of mo-tion of shoulder joint and healing grade of rotator cuff between the two groups 6 months after surgery(P>0.05).Conclusion Arthroscopic rotator cuff repair with all-suture anchor is feasible and safe,and has good short-term clinical effect.
RÉSUMÉ
Objective:To compare the clinical efficacy between reservation and sacrifice of remnants in the footprint area in arthroscopic repair of rotator cuff tear.Methods:A retrospective study was conducted to analyze the clinical data of 32 patients with rotator cuff tear plus remnants in the footprint area (2 cm < tear size <5 cm) who had been admitted to Department of Sports Medicine, The People's Hospital of Northern Jiangsu from May 2020 to July 2021. The patients were divided into 2 groups according to reservation or sacrifice of remnants in the footprint area in arthroscopic repair of rotator cuff tear. In the remnant-reservation group (16 cases): 5 males and 11 females with an age of (61.8±9.9) years, 9 left and 7 right shoulders affected, and (3.7±1.1) cm in size of rotator cuff tear; in the remnant-sacrifice group (16 cases): 4 males and 12 females with an age of (61.3±8.8) years, 8 left and 8 right shoulders affected, and (3.9±0.9) cm in size of rotator cuff tear. The 2 groups were compared in terms of visual analogue scale (VAS), American Shoulder and Elbow Surgeons (ASES) score, Constant-Murley shoulder function score (Constant score), and range of motion of the affected shoulder before surgery, 3 months after surgery and at the last follow-up. The ratio of bilateral abductor muscle strengths (affected side/healthy side) was analyzed and compared between the 2 groups, and the healing of the rotator cuff was evaluated by MRI at the last follow-up.Results:The 2 groups were comparable because there were no significant differences in all their preoperative demographic data ( P>0.05). The 32 patients were followed up for (14.3±3.5) months after surgery. At 3 months after surgery, the VAS score in the remnant-reservation group [1.0 (0.0,1.0) point] was significantly lower than that in the remnant-sacrifice group [1.0 (1.0,1.0) point] ( P<0.05), but there was no significant difference between the 2 groups in ASES score, Constant score or range of motion of the affected shoulder ( P>0.05). At the last follow-up, the ASES score, forward flexion, abduction and ratio of bilateral abductor muscle strengths (affected side/healthy side) in the remnant-reservation group [(96.1±4.8) points, 170.0 (170.0,170.0)°, 160.0 (160.0,170.0)°, and 85.5%±13.8%]were significantly better than those in the remnant-sacrifice group [(91.4±5.9) points, 160.0 (160.0,170.0)°, 150.0 (140.0,155.0)°, and 72.6%±16.9%] ( P < 0.05), but there were no statistically significant differences between the 2 groups in VAS score, Constant score, neutral external rotation angle, or body-side internal rotation ( P>0.05). The Sugaya grading for MRI rotator cuff healing was significantly different between the 2 groups at the last follow-up ( P<0.05). Conclusion:In arthroscopic repair of rotator cuff tear, reservation of remnants in the footprint area can significantly relieve postoperative shoulder pain, and has obvious advantages in restoration of shoulder forward flexion, abduction and abductor muscle strength, leading to better healing of the rotator cuff and the large nodule than the remnant-sacrifice technique.
