A Comparative Study of Arthroscopic Knotless Suture Bridge Fixation vs.Traditional Knot-tying Suture Bridge Fixation for the Treatment of Large Rotator Cuff Tear
Objective To compare the clinical efficacy of traditional knot-tying suture bridge fixation vs.knotless suture bridge fixation under arthroscopy in the treatment of large rotator cuff tears.Methods A total of 213 patients with large rotator cuff tears admitted to our hospital from January 2021 to December 2022 were selected and divided into two groups using a random number table method.The control group(106 cases)underwent traditional knot-tying suture bridge fixation under arthroscopy,and the study group(107 cases)underwent knotless suture bridge fixation under arthroscopy.The surgical time,pain level,shoulder joint range of motion,shoulder joint function score,imaging related indicators,quality of life score,re-tear rate,and complications were compared between the two groups.Results The surgical time in the study group was shorter than that in the control group[(74.85±5.22)min vs.(83.45±5.32)min],and the re-tear rate in the study group was lower than that in the control group(0.93％vs.7.55％).The incidence of complications was lower in the study group than that in the control group(2.80％vs.10.38％),and the difference was statistically significant(P＜0.05).The visual analogue scale(VAS)scores at each observation time point after surgery in both groups were lower than those before surgery in the same group.The American Society of Shoulder and Elbow Surgery(ASES),University of California Los Angeles(UCLA)Score,Constant-Murley shoulder function assessment scale scores,external rotation range of motion,forward flexion range of motion,and the MOS item short form health survey(SF)-36 scores were higher than those before surgery in the same group,and the differences were statistically significant(P＜0.05).Inter group comparison showed that the VAS scores of the study group were significantly lower than those of the control group at 7th day,3rd month,and 6th month after surgery.The UCLA,ASES,Constant-Murley scores,as well as external rotation range of motion,and forward flexion range of motion were significantly increased in the study group as compared with those of the control group at 6th month after surgery.The scores for each dimension of SF-36 at 12th month after surgery were significantly higher in the study group than those in the control group(P＜0.05).Conclusion Both traditional knot-tying suture bridge fixation and knotless suture bridge fixation under arthroscopy could achieve good therapeutic effects in the treatment of large rotator cuff tears.However,knotless suture bridge fixation surgery could significantly shorten the surgical time,alleviate postoperative pain in patients,promote shoulder joint function recovery,and reduce the incidence of rotator cuff tear and complications.
