Application of three-line anchors combined with modified Mason-Allen technique in repair of moderate to massive rotator cuff tear
Objective To investigate the therapeutic effect of three-line anchors combined with modified Mason-Allen technique in repair of moderate to massive rotator cuff tear under arthroscopy.Methods The clinical data of 48 patients(repair of moderate to massive rotator cuff tear using modi-fied Mason-Allen technique)were analyzed retrospectively.According to the anchors used,patients were divided into control group(double-wire anchors,n=23)and observation group(three-wire an-chors,n=25).Age,gender,operation time,the number of anchors used during operation and postop-erative complications were recorded in the two groups.American shoulder and elbow surgeon(ASES)scores,Constant-Murley shoulder function scores and Visual Analogue Scale(VAS)scores were com-pared between the two groups before and after surgery(last follow-up).During follow-up,magnetic resonance imaging(MRI)was used to evaluate rotator cuff retear.Results At the last follow-up,VAS score of the shoulder in the two groups was significantly lower than before surgery,constant-Mur-ley shoulder function score and ASES score were significantly higher than before surgery(P<0.05).The number of anchors used in the control group was significantly higher than that in the observation group(P<0.05).Conclusion The clinical effect of three-line anchor combined with the modified Mason-Allen technique in repair of moderate to massive rotator cuff tear is better,which is consistent with the traditional two-wire anchors,but the amount of anchors is less.
